Spiral Wound Gasket for Sealing

Spiral Wound Gaskets are made of a preformed thin metallic strip combined with a soft sealing composite material, wound together under pressure to energize the sealing element to act like a spring when compressed between two flange faces. The sealing element can be used stand-alone or in conjunction with inner and/or outer rings depending on the application.It is the precision-engineered solution for flanged joints, heat exchangers, boiler handholes, manholes, and other high-temperature, high-pressure applications—providing resistance to virtually every known corrosive and toxic element.

Spiral wounds are available in a full range of styles and materials and are manufactured in accordance with ASME B16.20 for use in all industry flanges, including ASME/ANSI B16.5, ASME B 16.47, Series A & B.

Many pieces of spiral wound gasket are piled together in the ground.
Various kinds of spiral wound gasket are on the pallet in the warehouse.

Various kinds of spiral wound gasket are designed to fit all kinds of industry flanges.

Small size wound spiral gasket can be put inside the big size in transportation.

In order to saving space during transportation, we can put the small size spiral inside the big size spiral.

Wound spiral gaskets are well packages.

We stick the sponge in the spiral wound gasket to avoid breaking caused by collision.
