Our SWG character:
1,good compression elasticity
2, high temperature and pressure resistance
3,Acid and alkali resistance
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.
If the gasket is used for heat exchanger, generally we recommend the one with φ3.2mm stainless steel inner ring.
The narrow-band form is divided into sticking type and covering type.
Steel belt and the inner and outer ring profile
General thickness mm
V-shape Gasket / Ring
W-shape Gasket / Ring
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:
D1inner diameter of the inner ringD2: outer diameter of the inner ring
D3inner diameter of the outer ringD4: outer diameter of the outer ring.
