Corrugated Metal Gasket consists of a metal core with concentric grooves on both sides, coated with expanded graphite or PTFE layer. The thickness of metal can be thinner, e.g. 3mm, 2mm, 1mm, 0.5mm, compared with Kammprofile gasket, and the corrugation pitch is 3mm, 4mm or 6mm depending on the width of the sealing face.
APPLICATION:
have been proven to be both reliable and cost-effective for flange and heat exchange application, especially used in low-pressure applications in large diameter flue gas ducts at high temperature, also suitable for uneven or distorted sealing surfaces. It eliminates the problem of difficult handing with large non-metal gaskets used in those applications.
ADVANTAGES:
◆Outstanding mechanical strength and thermal conductivity
◆Capable of withstanding high temperature
◆There are almost no limitations regarding size
◆Choice of insert metals easier
◆Trouble-free for handling and installation even for large size
