Metal spiral wound gasket:

Kun Yongjia County of valve parts plant (Www.kundamfj.com) metal spiral wound flange gasket: Zhejiang Kun of seals - metal graphite spiral wound gasket semi-metal gasket of resilient gasket HG 20610-1997 best steel pipe flanges with wound Gasket (European system), the V-shaped or W-shaped thin steel strip with a variety of fillers (graphite; asbestos; tetrafluoroethylene) alternately wound from its structural density can be based on different locking force requirement to produce and use inside and outside the steel ring to control the maximum degree of compaction, less precision gaskets in contact with the surface of the flange sealing surfaces. Especially suitable for uneven load, easy to relax bonding force, temperature and pressure changes periodically, there is shock or vibration occasion.

Zhejiang Kun of sealing - spiral wound gasket Category: Basic belong wound gasket; wound gasket with outer ring; with inner ring spiral wound gasket; wound gasket with inner and outer ring; the heat exchanger (with gluten), shaped spiral wound gasket Kun up. brand metal spiral wound gasket made of high quality SUS304, SUS316 ('V' shape or 'W' shaped) metal band and other alloy materials and graphite, asbestos, PTFE, non-asbestos and other soft materials overlapping spiral wound together, At the beginning and end of the metal strip by spot welding fixed Editors: Helin Ming 13,968,952,360 technical QQ1932722133

Metal strip with a thickness of 0.15mm ~ 0.25mm of 08F, 0Cr13, 0Cr18Ni19Ti, 0Cr18Ni9Ti, 00Cr18Ni10, 0Cr18Ni12Mo2Ti, 00Cr17Ni14Mo2 cold rolled strip.

The metal strip is preformed V-shaped or W-shaped narrow.

Stainless steel hardness values ​​HV≤200. Usually the width of the steel strip is 3.2mm, 4.5mm. 8mm nonmetallic filled with a special non-metallic materials with asbestos, flexible graphite tape, Teflon tape, non-asbestos fiber tape ceramic fiber and mica, etc. with a thickness of 0.3-1.0mm.. special loss on ignition of asbestos must be ≤25% non-metallic chloride ion content ≤100PPM belt. Recommended temperature of various types of media and various non-metallic belt . and the pressure is generally the width of the strip is 3.2mm, 4.5mm 8mm temperature: graphite spiral wound gasket temperature -200-850 ℃ asbestos spiral wound gasket temperature -200-500 ℃ tetrafluoroethylene metal spiral wound gasket temperature -200-260 ℃ with inner and outer ring, edging spiral wound gasket, sub-four basic forms for tenon slot flange gasket, with inner ring, for embedded convex surface flange gasket Gasket Gasket sheet, with inner ring for smooth Flat welding flanges, with inner and outer ring for smooth style welded flange back fine elastic metal spiral wound gasket pressure piping system capable of thermal cycling and vibration automatic adjustment.

Pad on the flange design for ease of installation, according to the gasket aperture size, the peripheral welding on the spacer 2 to 8 positioning belt, so buckle positioned on the flange hole when installing the gasket to prevent displacement or loss , saving auxiliary materials and working hours are generally divided into the following types:

Metal spiral wound gasket made of high quality SUS304, SUS316 ('V' shape or 'W' shaped) metal band and other alloy materials and graphite, PTFE, non-asbestos and other soft materials are alternately overlapping spiral wound made at the beginning and ends with a spot welding metal straps. metal spiral wound gasket for the semi-metallic gasket in the best resilient gasket, spiral wound gasket structure density requirements based on different locking force to make and use inside and outside steel ring to control the maximum degree of compaction, less precision wound gasket contact surface of the flange sealing surface. metal spiral wound gasket is particularly suitable for uneven load, easy to relax bonding force, temperature and pressure changes, has an impact or vibration of the occasion. wound gaskets are valves, pumps, heat exchangers, towers, manholes, hand holes and other flange connections for static sealing process want the original.
