What type of gasket should I use?

Assorted Gaskets Thumb

When faced with the task of selecting a gasket for any particular application, the amount of styles, materials, sizes and options on the market can make the job extremely difficult for the inexperienced of us. With gaskets being an essential component of all different types of equipment, vehicles and machinery the number of applications is literally endless and unfortunately there is no one-size-fits-all in the gasket game. But before we get into how best to narrow down the options on the market and select the best, lets quickly touch on why selecting the correct gasket is important.

Why is selecting the correct gasket important?

Incorrect gasket selection will obviously lead to leaks and blow-outs which may happen straight away or the gasket may not last as long as it should or could and will require replacing more regularly than necessary. In the worst instances leaking flange set-ups can also cause injury from contact with hot or toxic chemicals. Also, what most companies or businesses care about is their bottom line. Not using the correct gasket will cost you or your business money! So how can we try to mitigate this and select the correct gasket?

Learn every detail about your gaskets future environment.

The first step is to learn every detail about the gaskets future environment. This sounds like a daunting task, however there are really 3 main factors to assess and they are Temperature; what upper and lower limits will the gasket be required to handle? Pressure; how much pressure will be exerted on the gasket and Chemical Compatability; you need to consider what type of media the gasket be sealing, how corrosive is it? What is the level of ozone present?

temperature 900pressure 900Chemical 900

Evaluate the flange design and condition.

Once we know all we need to know about the environment that the gasket will live we need to know about where it will be housed which requires evaluating the flange design and it’s condition. There are about 7 different types of “normal” flanges that are displayed in the graphic below. As you can see in the graphic they all have a different construction and as a result, not all types of gaskets will work for each however the flange design will help to narrow down the list of possible gasket option so we need to take note of it.

Common Flange Types

We then need to check the condition of the flange and in particular the sealing surface. Some things to look out for are the presence of corrosion. Badly, corroded flanges are going to make it extremely difficult to achieve a good seal and may limit the range of styles available for use. Another detail to look out for are misaligned flanges. When flanges are misaligned flanges it is very difficult to achieve an even bolt load and eventually the gasket will fail even though it may not have been the gaskets fault.

Once we are happy with condition of the flange and we know what type of gasket options we are limited to because of a combination of the flange type and it’s future environmental factors, we are pretty much ready to select the style of gasket we will use.

Non-Metallic, Metallic or Semi-Metallic?

Now when selecting a gasket we have three different types that we can choose from and they are non-metallic which includes elastomeric materials (rubber’s) and compressed fibre, cellulose fibre, plastics and PTFE’s. Mostly these are materials that seal under relatively low bolt loads and although they can handle a fair amount of pressure in some cases, we are not talking anywhere near as much as gaskets that are reinforced with metal like those in our next style, semi-metallic.

As the name suggests, semi-metallic gaskets contain a mix of metallic and non-metallic materials and the most popular type in this range is by far the spiral wound gasket (SWG). In this segment alone there are so many different material combinations that you could almost construct a gasket for any application you can think of. The standard material combination for spirals utilizes steel reinforcing rings and winding combined with a graphite filler to seal, these spirals are mass produced and can be a very cost effective option for sealing in higher pressure environments. Other types of semi-metallics on the market are corrugated and metal jacketed gaskets which are both not as popular but have demonstrated superior performance in some individual applications and as such are still used.

Finally we have metallic gaskets. This category contains RTJ’s (Ring Type Joints) and Kammprofile gaskets. These are generally used for very high pressure applications and require a higher amount of bolt load to seal. They are often found in critical service applications such as oil and gas pipelines and refineries. Metallic gaskets are not cheap, but the applications that require them are generally not either.

C4430 Gaskets Stack

Gasket Sizing: Standard or Custom?

At this point we have by now selected the type of gasket we are going to use and what it will be made from which means all that is left is to determine what size it needs to be. In most applications the size will be determined by the nominal bore of the pipe and flange used. These are usually manufactured to a certain standard which may vary because of the country the equipment was manufactured or a range of other factors. Some of the most common standards encountered are:

  • ANSI (American National Standards Institute)
  • ASME (American Society of Mechanical Engineers)
  • DIN (German Institute for Standardization)
  • BS (British Standard)

These standards stipulate the size of the pipe, flange and therefore also the size of the gasket, how many holes it is to have, the size of the holes and location of the bolt circle (PCD). These gaskets are often known as “table gaskets” and sizing information for the most popular standards can be found by clicking this link.

Table Gasket Dimensions

In some instances, there may be cases where a standard has not been used and the gasket is completely custom. In these cases, it is up to the design engineer to determine the necessary size and thickness of the gasket.

What can I do if I am still not sure I have selected the correct gasket?

Talk to a gasket design expert! This is very important. If you are unsure about any of the previous steps or simply don’t have enough information you should not hesitate to talk to a gasket design engineer. In the sealing game there really is no substitute for experience and we have years and years of that here at AG. It’s not worth taking risks that may turn out to be extremely costly.

Dealing with Abrasion – Impact and Wear Protection Epoxies

Plastic Metal Ceramic BL being painted on to a centrex cone

Abrasion – An unavoidable nuisance

In the mechanical world, Abrasion is an often unavoidable occurrence that can cause headaches for owners, repairers and operators of all forms of plant equipment, vehicles and machinery. Abrasion may occur for many reasons including constant wear, erosion, scraping, rubbing, stripping or any other action that breaks down a surface over time.
Dealing with the effects of abrasion is a constant battle for mechanical engineers, who are tasked with getting the longest working life out of their plant infrastructure. The problem is particularly prevalent within industries involved in the processing of abrasive substances such as rocks, sand, slurry, ore and bitumen. So what is the best solution?

Ceramic BL Newsletter Image

An impact and wear-resistant protective coating.

The best way to protect from abrasion is by applying a wear and impact resistant coating such as Weicon Plastic Metal Ceramic BL. When mixed together and applied to a surface, this 2-Part epoxy compound creates an ultra-durable wear and impact resistant coating that is designed to withstand the effects of repeated abrasion and protect the underlying surface.

Weicon Plastic Metal - Epoxy Repair and Wear Protection Compounds

It works because of it’s formulated from an epoxy resin inbuilt with hard mineral reinforcing fillers. Once dry it forms an extremely hard surface layer that is blue in colour, glossy and smooth. Best of all, using an epoxy based wear compound such as Ceramic BL saves time and is generally cheaper than traditional methods of surface repair such as welding or replacement.

Because Ceramic BL bonds well to a wide range of materials, it can be used almost anywhere a protective coating is required. It adheres well to metals including steel, iron, aluminium, brass and copper as well as glass, ceramics, concrete, wood and many plastics. As such it is used heavily for protecting equipment such as pumps, chutes, hoppers, slides, pipes & augers on which the protective coating is applied and then re-applied once worn away, keeping the equipment’s original surface in tact. these are just a few applications however as the product literally has thousands of uses.

Pipe before coating with Weicon Plastic Metal Ceramic BlPipe after coating with Weicon Plastic Metal Ceramic Bl

Extremely easy to use.

German Engineering is known for it’s efficiency, which is why Weicon have made this product extremely easy to both prepare and apply. The pack even comes with a spatula and gloves – everything you need to get the job going. First, simply clean the Surface that you wish to coat as best you can (we recommend using a cleaner like Weicon Cleaner S or Surface Cleaner). Then mix the two components together (they are already in the correct ratio) and thoroughly stir. You can then pour, brush, trowel or dip to apply the epoxy mixture. Once it is completely dry, your coating is ready to protect.

Need to coat a large area? It’s also spray-able

That’s right! If you have a large area that needs covering, Ceramic BL can also be applied with an industrial pump spray applicator. The video below gives a better explanation of how this is achieved allowing large areas to be coated with ease and minimal wastage.

Other Styles Available

There are many more grades available in the Plastic Metal range that may better suit your application. These include grades for high temperature applications, anti-magnetic applications as well as grades that set underwater and provide superior resistance to chemical attack. For more information on the entire range, we recommend heading over to our Plastic Metal range comparison page.

Reduce Friction, Corrosion and Wear with our Anti-Seize Lubrication Pastes and Sprays

Weicon Anti-Seize Range Image Banner Image - Available from Associated Gaskets

Moisture, friction and all kinds of other influences can lead to damage such as corrosion, wear and even the seizure of machines and installations. Extensive repair and maintenance work, at considerable cost, is the result.

These problems are even more pronounced when the application conditions feature one (or more) of the following:

♦  High operating temperatures.
♦  High pressure loads.
♦  Exposure to the weather.
♦  Aggressive chemicals.
♦  The influence of other media.

Our Weicon range of Anti-Seize Assembly Pastes have been specially developed for these requirements. They are used as protecting and separating agents (and lubricants) for highly stressed parts, especially at high temperatures.

Anti-Seize Stops Corrosion and Seizing on a bolt

In many demanding industrial applications, convention separating agents or lubricants (such as mineral oils and greases) cannot provide sufficient lubrication and protection. Since they are based on optimally balanced solids and specially selected additives, the Weicon Anti-Seize range can be used in these extreme environments, and provide long lasting performance.

The basic components in our Anti-Seize solutions are made from synthetic oils. These have a considerably lower sulphur content than products containing mineral oil. A residue-free vaporisation of the oil at temperatures between +200°C and +250°C is therefore possible.

This is particularly important in the case of stainless steels (e.g. for VA material) to prevent stress-corrosion cracking.

Due to the special formulation and the very fine grinding of the solids contained in Weicon Anti-Seize, irregularities in the surface being protected are completely filled – even to a layer thickness of only 12 μm. Only a perfectly sealed surface guarantees a reliable protection against corrosion. An additional sealing effect thus results for special applications, such as flange connections.

Weicon Anti-Seize Lubricating and Assembly Pastes protect against the following:

♦  Corrosion, seizure and wear.
♦  Stick-slip phenomena.
♦  Oxidation and fretting corrosion.
♦  Electrolytic reactions (aka cold welding).

All grades of Weicon Anti-Seize are free of sulphurous additives and halogens. They have good adhesion characteristics and are abrasion proof. They are also resistant to hot, cold and salt water. Their extremely low friction also allows for easy disassembly of treated components when it is required.

Anti-Seize Spray being applied to a flange face

In addition, Weicon Anti-Seize assembly pastes are excellent lubrication for statically high-stressed parts and slowly rotating machines (as long as corresponding re-lubrication intervals are observed).

With their dual capabilities as lubricants and corrosion protection agents, Weicon Anti-Seize offer the benefit of rationalisation; in terms of saving time, reducing the need for multiple maintenance products, and reducing costs.

These products are used quite sparingly. At a layer thickness of 0.01mm, 1kg of Anti-Seize is enough to cover a surface area of approximately 45m².

Our 4 Types of Anti-Seize Assembly Lubricants.

To suit the needs of different applications we are pleased to offer four different types of Anti-Seize. These are high quality, long lasting and effective lubrication and protection products but their composition and performance capabilities differ.

Together the four different grades cover everything from common marine, automotive and facility maintenance work, to demanding food grade, high temp or aggressive chemical applications. All are available in a range of sizes and container styles and the differences between each is summarised below:

VKA Welding Load Test: 2000 N (DIN 51350)

The assembly paste was developed to resist extreme conditions. It is highly sticky, water repellent and resistant to sweet, salt and hot water as well as steam. The high nickel component furthermore provides protection against corroding and corrosive solvents which are contained in diluted hydrochloric acid, sulphur or nitric acid, among others. Anti-Seize Nickel can be applied at a large temperature range between -30°C to +1,450°C.

Anti-Seize Nickel serves as corrosion protection and high-performance fitting grease for static and dynamically extremely stressed screw connections and installation parts and the application at slowly rotating system in the high-temperature range.

The paste protects against corrosion, seizing, wear, stick-slip effects, oxidation and friction corrosion as well as electrolytic reactions, the so-called cold-sealing. For example, Anti-Seize Nickel can be used on seals, valves, screw connections, gear wheels, bearings, jets, conveyor belts, studs, tools or cylinders.

Could Ceramic Insulation Paper Solve Your Temperature Woes?

Ceramic Fibre Paper Glass; Thermal Insulation;

One of the main problems generally encountered when searching for a high temperature insulation material is that in order to withstand elevated temperatures, a trade-off is usually made with mechanical strength resulting in materials that are brittle, porous, fibrous and generally difficult to handle. If these properties are what are causing trouble in your high temperature insulation application, then you may want to read on and find out more about AG’s Lytherm Ceramic Insulation Paper.

Really, a heat resistant paper?

We know it sounds strange but Lytherm isn’t your normal paper manufactured from organic tree wood. It’s actually manufactured from high purity alumina-silicate fibres. These are ceramic-based inorganic fibres that are often used as a refractory material in many high temperature industrial applications and processes where temperatures reach over 1000ºC.

The fibres are washed and spun in a special process to remove foreign particles and to control the content of unfiberized shot. The resulting product is a thin, white sheet material that is lightweight but strong.

Lytherm Ceramic Insulation Paper Close-Up

 

What are the advantages of ceramic fiber paper?

Ceramic Insulation Papers offer many advantages over other forms of insulation. They are thin, flexible and lightweight while still able to remain extremely stable and easy to handle. Lytherm is so stable that even when exposed to water, steam or oil it will return to its original thermal and physical properties upon drying!

Lytherm also exhibits extremely low thermal conductivity and heat storage. This makes it particularly useful for heat containment in tight places or where a uniform thickness material is required. It is also resistant to a wide range of chemicals meaning it can be used in a diverse range of applications.

Other benefits include:

♦ Excellent compression recovery (very important for sealing).
♦ Good dielectric strength.
♦ Low heat storage.
♦ Very little shrinkage. Even at extreme temperatures.

Best of all it can be cut into shapes, wrapped, formed or slit into rolls without falling to pieces. This means you can achieve the exact shape of insulator that you require.

Lytherm Cermic Fiber Paper Compressed

 

Where is ceramic insulation paper typically used?

Ceramic insulation papers are mainly used as lining materials, for high temperature seals, primary insulation or as a filler. Within these broad descriptions, there’s a lot of specific uses. Just some of them include:

♦ Lining of doors and walls for furnaces and kilns.
♦ Insulation for wood-fired pizza ovens.
♦ Lining and insulation for glass making.
♦ Making high temperature gaskets and seals.
♦ Insulation around engines and exhaust systems in the marine and automotive sectors.
♦ Pump insulation.
♦ As a filler for insulation batts and blankets.

These really are just some of the countless applications we’ve seen for Lytherm ceramic paper over the years. If you think Lytherm might be suitable for your application, it’s worth speaking to one of our experienced customer service team members. They’ll be happy to help with information on sizes, fabrication options and anything else you need to know.

Ceramic Fibre Paper Glass

Is there anything to be aware of?

Most grades of Lytherm Ceramic Insulation Paper contain a low percentage of organic binder that may burn off when initially exposed to elevated temperatures. In most applications, this should not be a concern – merely something to be aware of.

In applications where this could be an issue, AG can also supply a completely inorganic binderless grade. This specialised type is able to handle temperatures up to 1650ºC whereas the standard grade is rated to a (still fairly impressive) 1260°C.

To find out more about this product including what thicknesses and sizes are available we suggest heading over to the product page on our website where you will be able to find all the technical data. Alternatively, to learn more about all the fabrication options we offer for our Lytherm paper, you can get the details of your local AG branch here.

New Video on our Flange Spray Shields for Plant and Personnel Protection

Leaking Flange with Spray

AG’s Flange Spray Shields are safety devices that are designed to prevent hot, caustic or toxic chemicals from making contact with plant equipment or personnel and causing injury or harm. They wrap around the flange, effectively stopping wayward spray that can occur in the event of a gasket leak or blow-out.

If your workplace is serious about preventing accidents at work, then the use of flange spray shields is a must. To find out more about these simple to install, effective and long lasting safety guards watch the video below….

 

Vinyl Flange Spray Shields

Our Vinyl Flange Safety Spray Shields are made from a yellow re-enforced polyvinyl chloride fabric. Fabricated with 3-Ply multi layers and utilizing a tough polyester thread and draw cords. They have a maximum operating temperature of 76ºC and are UV stabilised whilst being resilient against the external elements such as rain, emissions and sunlight.

Each cover comes with a pre-installed bleed hole that is covered by a PH indicator, providing easy identification as to if a leak is present. This patch is replaceable meaning that the spray shield is suitable for use again, if it has been exchanged. They are available in ANSI, DIN and PN flange sizes and are easily installed by a single person whilst at the same time ensuring that the safety of others is kept. Use of our Spray Shields also assist organisations meet new regulations set by agencies such as OSHA, EPA, MSHA, SOLAS, ABS and DNV.

PTFE Flange Spray Shields

AG’s PTFE Flange Spray Shields are manufactured with a high quality PTFE coated fibreglass cloth and an easy-view PTFE central strip. Fabricated utilising either a PTFE coated fibreglass or Nomex® thread and draw cords, they have a maximum operating temperature of 204ºC. The Spray Shields are UV stabilised and are resilient against the external elements such as rain, various emissions and sunlight.

Super-Tack – Fast, Strong Adhesive Demonstrated in our New Video

Weicon Flex 310 M Super-Tack is a fast, strong adhesive sealant. Made from MS Polymers, it is completely free of silicone and works well on most materials including metal, ceramics, wood, glass, stone and many types of plastic.

It’s real claim to fame though is its very high initial bond strength. Super-Tack has a skin-over time of just 10 minutes but it’s adhesive effect is almost instant. This makes it ideal for bonding vertical surfaces and allows it to be used to replace screws, pegs, rivets and other traditional types of fastener.

The video below shows just how easy it is to use and then puts it to the test by having it support the towing of a car.
