Description：
Consists of laminated V-shaped or W-shaped stainless steel tapes and soft non-metallic filler that are simultaneously wound on a rotating mandrel.
Application:
With perfect compression recovery, it provides longer and better sealing under heavily alternating temperature or pressure such as the static sealing at flanges of pipeline, valves, pumps, heat exchangers, columns, manhole and handhole. It has a wide application in petrochemical, mechanical, electric power, metallurgical, ship-building, pharmaceutical, nuclear power and aerospace industries.
