Description   Gaskets are used to prevent fluid or gas leaks by providing a barrier between two mating surfaces. The gasket must be able to maintain a seal under pressure and temperature changes. A number of different gaskets are available: pre-cut compression (flat or extruded style), formed-in-place, and cured-in-place. Some gaskets and gasketing can also be used to shield against electromagnetic and radio frequency interference (EMI/RFI).    Types Common types of gaskets...

Design TrendsTop

Q:
What new technologies are influencing gasket and gasketing design?
18 answers
Answers:
Some of the new technologies that currently have major influence are : Spiral would gaskets are being replaced with steel trap / self locator gaskets - that can be used across the various pressure ratings. Kammprofile Gaskets - that features excellent anti-blowout properties together with the reliability of a solid metal-to-metal seal combined with a soft sealing face to provide a perfect joint - now being used with heat exchangers, vessels and reactors and various flanged connections. Rubber steel ring gaskets = Rubber steel gasket with vulcanized steel ring for safe centering and perfect sealing according to DIN EN 1514-1.

Products for high temperature. Ease of use. ASME B31.1 & B31.3 piping flange gaskets that are one style fits as many applications as possible (e.g., same gasket for pressure & vacuum service) so we can eliminate installation errors.
~Dave M., Design Engineer, Sarnia, Canada
New development in materials has a very important influence in gasketing design like, grafoil, Teflon insert, rubber gaskets

Q:
From your perspective, which companies are creating the most innovative gaskets and gasketing?
21 answers
Answers:
It greatly depends on the equipment manufacturers, we have local manufacturers like: Al Iman in KSA.
~KSKABEER K, PLANNING ENGINEER, KUTTIADY, INDIA
Flexitallic and Lamons are probably the ones leading the pack in gasket innovations.
~Marketing/Sales, Scarborough, Canada
We have standardized on Flexitallic, JM Clipper, and Klinger gaskets.

Applications and UseTop

Q:
What are some of the applications you have used gaskets and gasketing for?
37 answers
Answers:
Used in some high temperature, high pressure as well as critical service applications. Some of the common applications that I have used gaskets are for pipe flange, heat exchanger, compressor and bonnet valves. Some of the other applications are valves and pipework assemblies, along with some high integrity pressure vessel joints.
~Marketing/Sales, Scarborough, Canada
Sealing underwater battery pods, diving habitat doors & windows. Also for sealing the heat exchanger in a diver's hot water unit.
~Engineering, Design, Singapore, Singapore
A high temperature steam generator, and a very high temperature small lab scale gasification furnace etc.

Q:
Please share with us any “non-standard” applications that gaskets and gasketing have been used for.
10 answers
Answers:
All of the heat exchanger assemblies with double gasket assembly and leak of lines are non-standard, the valve bonnet and the pump bolted joint assemblies as well, self energized manways on the tanks, the boiler manways, etc. True and real technical support have been constantly increasing reliability of those assemblies.
~Art S, Design Engineer, Bowmanville, ON., Canada
Used one piece for sealing a gap between a tube and a thermocouple inserted in it. The gasket material was flexible and served well.
~Sameep D, Student working as Research Assistant, Laramie, WY
Non-standard applications that I can think of are: Acoustic sealing cryogenic applications reactor vessels

Q:
Do you know of any disastrous mistakes that occurred due to the incorrect usage of gaskets and gasketing?
10 answers
Answers:
If you do not put in the proper size, material and pressure class of gasket and you do not properly install and torque the gasket you could have a catastrophic failure where there could be injury, or even death due to improper application.
~Joe P, Technical Sales Rep., Vandergrift, PA
Wrong selection of gasket resulted in process gas leaking to the atmosphere and fire.
~KSKABEER K, PLANNING ENGINEER, KUTTIADY, INDIA
Teflon grooved gaskets creeped under Metane high pressure resulting in a dangerous leak.

FeaturesTop

Q:
What would your design or feature "wish list" be for this product?
15 answers
Answers:
An effective and cheaper alternative for Ceramic fiber material for high temperature applications. A good rubber material that could answer both high temperature requirements & resistance to chemicals & strong acids ( something better than Viton in maximum temperature limit ).
~Marketing/Sales, Scarborough, Canada
High temperature capability, high pressure, chemically inert, ease of installation, but must be cost effective.
~Joe P, Technical Sales Rep., Vandergrift, PA
Soft, something that can be cut/extruded in a shape we need. Again, high temperature application is the point.

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using gaskets and gasketing?
15 answers
Answers:
Make sure that your supplier knows gasketing and applications, have your people trained in the installation and handling of gaskets. A good supplier should be able to ask the right questions before supplying a gasket for your application. Just because you have used a certain gasket before does not mean that it is the best one for your application.
~Joe P, Technical Sales Rep., Vandergrift, PA
Don't get driven by the gasket price and don't blame the gasket for failure of the assembly. Somebody has decided to use certain gasket there and somebody was trying to install it there to maintain the seal; was the joint designed for maintenance or for the assembly?
~Art S, Design Engineer, Bowmanville, ON., Canada
To verify the material offered, quality of the products and of course pricing & delivery time.

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of gaskets and gasketing?
13 answers
Answers:
Just because there was a certain type of gasket in the application does not mean that this is the best material and type of gasket for your application. Ask questions of your supplier and do not let price drive the purchase, cheap is not the best way to go to achieve reliability and leak free installation; a good supplier should have the ability to be cost effective yet give you the best material for your application. Proper sizing of gaskets and proper thickness is imperative for leak free application; there is a huge misconception that thicker is better and that is not the truth, in most applications where the flanges are in good condition and not warped, pitted, corroded or clean of debris, the thinner the gasket the better it will seal. It takes less load and torque to seal a thinner gasket than a thick one.
~Joe P, Technical Sales Rep., Vandergrift, PA
Make sure you understand your application. Choose a supplier who has engineering service backing him up. Give the supplier's engineer ALL the info you know about the installation, ESPECIALLY what hasn't worked in the past.
~Dave M., Design Engineer, Sarnia, Canada
Recognize the fluid conditions, the design of the assembly, the time in between failures, access to the assembly and the control of the clamping forces maintaining the seal; use thin gaskets.
