Flange Gasket
Flange gaskets are divided into asbestos gaskets, rubber gaskets, graphite gaskets, metal winding gaskets (basic type) are made of standard high quality SS304, SS316 (“V”-shaped or “W”-shaped) metal bands and other alloy materials with graphite, asbestos, PTFE, Flexible materials such as graphite, asbestos, PTFE, non-asbestos, etc. overlap each other and spiral winding, and at the beginning and the end of the spot welding method to fix the metal belt and become. Its role is to be placed in the middle of the two flanges to play the role of sealing.
Overview
Introduction:
Performance: high temperature, high pressure, corrosion resistance, with good compression and resilience.
Application: Petroleum, chemical, electric power, metallurgy, shipping and other connections of the pipe, valve, pump and other pressure vessels and heat exchange equipment sealing parts is the ideal static sealing material.
Stainless steel belt shape: “V” “W” “SUS” “U”. Stainless steel strip material: A3, 304, 304L, 316, 316L, Monel Monel, Titanium Ta.
Non-metallic belt (filler): special asbestos, non-asbestos, flexible graphite, PTFE, etc.
Adaptable temperature: -196℃--+870℃ (flexible graphite) ≤ +250℃ (PTFE) ≤ +500℃ (special asbestos)
Medium: Suitable for high temperature and high pressure vapor, oil, oil and gas, solvent, hot kerosene, etc.
Using pressure: ≤ 300Mpa Maximum processing size: 2800 mm;
Special specifications or all kinds of non-standard products can be made and produced according to your requirements.
Minimum preload ratio pressure: y=68 MPa
