Kencotube is a leading manufacturer & trader of Plate Raised Face Flanges, which has grooves cut into their faces that accept steel Ring Gaskets. The seal when tightened bolts compress the gasket between Stainless Steel Plate Raised Face Flanges into the grooves, deforming the gasket to make Intimate Contact inside the grooves, creating a metal to metal seal. Carbon Steel Plate Raised Face Flanges may have a raised face with a ring groove machined into it, where this raised face does not serve as any part of the sealing means. Alloy Steel Plate Raised Face Flanges seal with a flat gasket, formerly made of asbestos but now made of more environmentally friendly material, designed for installation between the raised faces of two mating flanges. Alloy 20 Plate Raised Face Flanges have a prescribed texture to increase their gripping and retaining force on this flat gasket.
Meanwhile, some users of Duplex Steel Plate Raised Face Flanges specify the use of spiral wound gaskets. The feature of Super Duplex Steel Plate Raised Face Flanges will hold the gasket concentric with the bolt circle and bore to make precise assembly easier with the gasket centered on the flange sealing surfaces. In this case the already coined gasket in Monel Plate Raised Face Flanges will not bear additional load beyond the bolt tension, vibration and movement cannot further crush the gasket and lessen the connecting tension. Kencotube as well offer these flanges at finest rates in different sizes to our clients.
