VALQUA No. 6500AC

 

Anti-corrosion Compressed Non-Asbestos Fiber Sheet

Compressed Non-Asbestos Fiber Sheets are rolled and vulcanized sheet type gasket materials, in which special rubber binders and a small amount of filler material are mixed with organic and inorganic fibers.

With reduced amounts of leachable chloride, these Compressed Fiber Sheets have corrosion suppression effect when stainless steel flanges are used for water or water solutions. Surface finishing reduces sticking to the flange.

 

Description

Unsuitable fluids Strong acid, strong alkali, and various solvents, inflammable gas, gas susceptible to burn and toxic gas
Applications Stainless steel pipe flanges, valve bonnets and other equipment used in various industries requiring corrosion resistance
Dimensions Width × Length (mm): 1270 × 1270、1270 × 3810、2540 × 3810
Thickness (mm): 1.0、1.5、2.0、3.0
Color type: blue
Print color: orange
