ASME B16.20 Spiral Wound Gasket,UNS N06625 SWG,Inconel 625 Spiral Wound Gaskets,
Description:Alloy 625 (UNS N06625) is an austenitic nickel base superalloy possessing excellent resistance to oxidation and corrosion over a broad range of corrosive conditions. Even temperature to 1100 degree C, alloy 625 also has exceptional fatigue resistance.
The material possesses a high degree of formability and shows better weldability than many highly nickel-base alloys.The alloy is resistant to intergranular corosion even in the welded condition.

Corrosion and Oxidation Resistance:
The high level of chromium and molybdenum in Alloy 625 provides a high level of pitting and crevice corrosion resistance to chloride contaminated media, such as seawater, neutral salts, and brines;
Tests in geothermal brines indicate Alloy 625 is highly resistant to hot geothermal fluids comparable to Titanium Grade 2;
Tests in simulated flue gas desulfurization environments show Alloy 625 highly resistant to the environment in comparison to a

Spiral Wound Gasket is Filler materials used are Graphite, Non asbestos material, PTFE..Inner & Outer Rings are also used as per customer specifications.
ASME B16.20 Spirak Wound Gasket, which is sophistically made by spirally winding a pre-formed metal strip and stuffing on the external periphery of metal winding mandrels. Moreover, our gaskets find extensive application in oil refineries power plants, petro chemical industries and marine fertilizer industries. Further, these spiral wound metallic gaskets are well known for its strength and brilliant performance.
