What Are Compression Controlled Gaskets?02 November 2016
Gasket fabrication technology produces reams of high-quality joint seals, but they’re not exactly designed to be dimensionally precise. After all, their primary function is to create an unbreakable seal, not to advance some difficult-to-achieve structural ideal. Of course, this idealised form is available, but only compression controlled gaskets can properly foster such accurate outlines when extreme tightening forces are doing their utmost to corrupt a gasket’s dimensionally assured outlines.
What are Compression Controlled Gaskets?
This sealing medium compresses intelligently when fastening forces exert great force on a joint. In other words, the gasket spreads smartly when it’s sandwiched between two sealing faces. Imagine the benefits of this non-compressible material. It won’t spread beyond the boundaries of delineated gasket space, so no untidy edges are exposed to the internal or external pipe joint. This is an especially handy feature when internal flow conditions are sensitive to material interference.
Flush Unions Support Sensitive Fluid Conditions
As the gasket lays flush at the joint union point, no “dead spots” will form. Instead, the fluid is conducted smoothly from one pipe section to the next. This singular flow-smoothening characteristic is viewed as highly important in certain applications. Subsequently, the food and pharmaceutical industry both employ compression controlled gaskets because system engineers are upholding a regulated hygiene methodology. Basically, the addition of an intersection aid that creates a seamless seal serves to reinforce hygiene-centric design practices.
Creates Extrusion-Free Unions
A vulcanised Ultem resin regulates the compression force applied by mechanical fasteners. The gasket material within the ring of non-compressible resin then conforms to the ferrules of the mechanical bore juncture to form a flush interface, an uninterruptible bridge between system-critical fluid channels. The design is recognized as a perfect fit for sanitary-sensitive applications, so it’s found in conduits that carry foodstuffs and beverages. Likewise, many chemical and medical fields employ the gasket when seeking to eliminate the inline dead spots that could provide shelter for bio-contaminants. Interestingly, the lifespan of this sealing product is also extended by its flattened profile, for no stray edges are protruding into the flow, so the gasket doesn’t wear as quickly as general-purpose sealing products.
These are specialised gaskets. They’re designed to excel in situations where dimensional accuracy is a major asset. A tabbed kit takes sanitary considerations to the next logical feature plateau by ensuring finger contact is minimised. All handling and installation work is done via the tabs, all so that a hygiene-oriented union is fully realised.
