Description: GOT-400 Spiral Wound Gasket is accumulated, hovered and wound, and spot welded beginning and end terminal by V-shaped or W-shaped stainless steel and non metal filler, which has good compression elasticity, and is suitable for the sealing parts with temperature and pressure altering violently. It is a static sealing parts used for such flange connecting joints as pipeline, valve, bump, heat exchanger, tower, manhole, and hand hole, etc. It is widely applied in departments as petrochemical, mechanical, electric power, metallurgy, boat building, medical, atomic energy, and aerospace, etc.
We can produce according to standards as ANSI B 16.20，MSS SP-44，API 605，DIN，JIS，JPI，BS 1560，JG/T，GB/T，HG，SH, etc. Or the demands can be designated in detail by clients. E.g. the gasket used for heat exchanger and with ribs, please provide the detailed drawings.

Generally the material of the inner ring is steel belt, to satisfy the medium and the working condition demands,
The outer ring material is the same as the pipe and the related equipment shell, the carbon steel outer ring is relatively economic.
The detailed order should indicate the detailed material, the used standard, the inside exhaust pipe nominal diameter DN, the pressure grade PN, or indicate the detailed size:
D1：inner diameter of the inner ring；D2: outer diameter of the inner ring；
D3：inner diameter of the outer ring；D4: outer diameter of the outer ring
The default thickness of the gasket is 4.5mm，and the ring 3mm
