Flexitallic Sprial Wound Gaskets - .PDF file.

The Flexitallic Spiral Wound Gasket has been designed to meet exacting conditions of both temperature and pressure in flanged joints and similar assemblies.

It has also been designed to be against virtually every known corrosive and toxic media The concept of spiral wound gasket construction was originated by Flexitallic in 1912.

The primary purpose for this development was the increasingly severe temperatures and pressures used by US refinery operators in the first half of the century.

It is important for a gasket to have the ability to recover.

The effects of pressure and temperature fluctuations, temperature differential across the flange face, together with bolt stress relaxation and creep, demand a gasket with adequate flexibility and recovery to maintain a seal even under these varying service conditions.

The Flexitallic Group is the international market leader in the manufacture and supply of high quality, high value industrial static sealing products.

Developer of the spiral wound gasket in 1912 in the US, Flexitallic continues its legacy of innovation with product materials like Thermiculite and Sigma. In 1998 Flexitallic set a new standard for sealing technology with the introduction of Thermiculite gasket material. Thermiculite is now available as tanged sheet, filler material for spiral wound gaskets and as a facing on kammprofile gaskets. This material solves numerous end user problems, particularly those with high temperature processes where traditional sealing materials fail. Thermiculite Critical Service materials are rated for temperatures up to 1000C and pass the API 607 fire test.

Flexitallic's global customer service network of owned manufacturing facilities, licensees and global distribution network ensure local demand is met quickly, with a combination of the highest product quality and customer service. With a varied product offering that includes spiral wound gaskets, semi-metallic gaskets, RTJ gaskets, Kammprofile, sheet gaskets, and dynamic and static packings, The Flexitallic Group draws upon its storied past and present day mixture of leadership, quality, service and technology to develop sealing solutions for industry all around the world.
