The spiral wound gaskets TR/TAC/TAI/TACI are composed of a sealing element which combines a metal strip and a strip of softer material (FM, PTFE, Graphite, Mica, etc.) wrapping both strips in concentric spirals with a DC voltage. The spiral wound gaskets are indicated in flanges and joints valve bodies, in the sealing doors of boilers registration and inspection, shutters (manhole and handhole), heads, heat exchangers, autoclaves and engine exhausts.

The manufacturing is based on the standard ASME B16. kockás nyerögépes játékok ingyen letöltés 20 and can be manufactured under plane, with different materials as AISI 304, 316L, 321, 347, INCOLOY 800, INCONEL 600, MONEL 400, etc.

The Spiral wound gaskets are manufactured with or without ring; the inner ring avoids direct contact flow with the sealing element, besides avoid the flow’s process accumulation on the flanges, decreases the corrosion risk and reduce the turbulences.

TR type: Without ring

TAC type: With external ring

TAI type: With internal ring

TACI type: With internal and external ring
