Double Jacketed gaskets are one of the most important
semi-metallic gaskets that due to metallic material strength and ability of
filler compressibility are suitable for sealing in narrow flanges and complex
shape surfaces with high pressure.
The main use of this type is in heat exchangers and
valve’s caps. These gaskets include metallic shell (Soft Iron, SS304, SS316 and
SS321, …) and non-metallic filling material (ASB, GRPH, PTFE and CERAMIC). The
filling material causes flexibility and the metallic cover causes gasket to
resist against pressure, temperature and corrosion. The typical thickness of
these gaskets is 3.2 mm.
The common partitions of this gasket includes 2
Partition, 3 Partition, 4 Partition, Z Partition, Y Partition and … .
Behta Industrial Gasket Co. can produce these gaskets in
various forms and materials according to API 601, ASME B16.20 standards.
