Description:
Spiral wound gasket Is formed by the V-shaped or W-shaped stainless steel belt and non-metallic filler through lamination, spiral winding, and spot welding of the tops and ends. With good compression elasticity, it is applicable to the sealing parts under the intense alternating temperature and pressure, as the static sealing elements at the flange joints of pipelines, valves, pumps, heat exchangers, towers, manholes, handholes, etc. Its widely used in petrochemical, machinery, electric power, metallurgy, shipbuilding, medicine, atomic energy, aerospace and other fields.
Standards:
Products are manufactured in accordance with all relevant gasket standards to suit flange designations: ASME B 16.20, ASME B 16.5, BS1560, ASME B 16.47 A (B), BS EN 1092, DIN, JIS, and NF, etc.
Color cord as ASME B 16.20 on request.
