PTFE ENVELOPED GASKETSAn insertion is made from a soft material, corrugated stainless steel or rubber and then enveloped with virgin PTFE. PTFE enveloped gaskets are used for flange joints where extreme chemical resistance is required. Gaskets have good pressure stability under different applications.
Flat-flange gaskets are produced in several sizes according to standard or customer design. Gaskets of up to 1,500 mm x 1,500 mm are made from one piece, while larger ones are assembled from segments. GASKET MATERIALS Most common used gasket materials are compressed fibre sheets, expanded graphite, PTFE, mica and elastomeric materials. GASKET SIZES AND DIMENSIONS Standard gaskets are mostly made according to EN 1514-1, ANSI B16.21 or other standards. Gaskets of dimensions up to 1.500 mm x 1.500 mm are made as one-piece, while larger ones are assembled from segments. There is no special limit for metal eyeleted gaskets. |
