Anti-stick compounds coat gaskets so that maintenance techs can easily remove aging ring seals. If fibre or polymer reinforced gaskets didn’t include non-stick plating, how could a tech remove a used seal? Remember, when it was installed, torque-tensioned bolts crushed the material against two flange faces. Sure, that action does prevent pressurized fluids from creating […]
Constant seating stress gaskets function as flange-interface fulcrums. That’s a difficult term to interpret, especially for non-engineering types. Picture a gasket with a uniform carrier ring. This incompressible metal annulus absorbs the bulk of sealing stress as a ring of pattern-tightened bolts pulls two flange faces together. Cleverly placed at a stress-neutral location on the […]
Polyurethane is a remarkable material. Used in gaskets, the infinitely adaptable polymer takes advantage of its resilient molecular structure to create a whole range of industry-leading products. Adhesive substrates and industry foams have drafted in many different urethane enhanced products. Similarly beguiled by the polymer’s application resistive properties, the gasketing sector hasn’t been slow in […]
Polytetrafluoroethylene, which is also known by abbreviation aficionados as PTFE, is a versatile gasket material. It’s a fluoroelastomer, a synthetic compound that’s available in many forms. On switching over to ePTFE (Expanded PTFE), the carbon-fluorine compound gains new mechanical properties. Classed as a popular sealing material because of a talent for resisting chemical attacks, ePTFE […]
Once upon a time, so the story goes, asbestos gaskets were commonly in-use because they provided exceptional thermal strength. The fibrous, silicate-based mineral obviously still exhibits superior heat-resistance fortitude, but asbestos is now recognized as an environmentally hazardous material, too. Known for some time now, the tiny fibres cause life-threatening lung diseases. No matter, a […]
