6500AC

Compressed Non-Asbestos Sheet Anticorrosion Type

Version of No.6500 with anticorrosion treatment and antistick treatment.

Used as gasket for stainless steel pipe flange and as gasket for equipment joint, cover, etc. Stainless steel corrosion inhibition is expected.

Temperature range : -50 to +183℃

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
