Spiral wound gasket manufacturers offer factory prices spiral wound gasket, spiral wound gasket manufacturers role of spiral wound gasket manufacturers offer factory prices spiral wound gasket, spiral wound gasket manufacturers role, spiral wound gasket for the semi-metallic resilient gasket in the best gaskets, V-shaped or W-shaped by a thin strip with a variety of filling materials (graphite, asbestos, PTFE) alternately entwined, its structure density can be based on different locking force required to produce and use both inside and outside steel ring to control its maximum compaction degree, gasket contact surface of flange sealing surface less precision. Especially suitable for uneven loads, easy to relax the engaging force, temperature and pressure changes periodically, where there is an impact or vibration. Are valves, pumps, heat exchangers, towers, manholes, hand holes and other static sealing flange connections originals widely used in petrochemical, machinery, electric power, metallurgy, shipbuilding, medicine, atomic energy and space sectors. Main use: Suitable for large diameter pressure vessel (such as heat exchangers, reactors, etc.) flange sealing a metal strip material A. 0.15mm ~ 0.25mm thickness using the 08F, 0Cr13, 0Cr18Ni19Ti, 0Cr18Ni9Ti, 00Cr18Ni10 , 0Cr18Ni12Mo2Ti, 00Cr17Ni14Mo2 such as cold-rolled steel strip, or negotiated by both parties. B. preformed metal strip is V-shaped or W-shaped narrow, the surface should be smooth. Clean, there should be rough, cracks, scratches. Defects such as pits and rust C. Stainless steel hardness value HV ≤ 200 D. General strip width is 3.2mm, 4.5mm.8mm 2. nonmetallic material A nonmetallic filled with special asbestos tape, flexible graphite tape, Teflon tape, non-asbestos fiber tape, ceramic fiber and mica, etc. . With a thickness of 0.3-1.0mm. B. Special asbestos LOI must be ≤ 25% C. metal straps ≤ 100PPM D. chloride ion content of various media and various non-metallic belt recommended temperature and pressure E. General of the strip width is 3.2mm , 4.5mm.8mm temperature: temperature graphite spiral wound gasket asbestos spiral wound gasket -200-850 ℃ temperature -200-500 ℃ PTFE spiral wound gasket temperature -200-260 ℃ mainly gaskets, PTFE products, graphite products, packing and so on. Such as gaskets categories: spiral wound gasket, graphite composite pad, graphite packing ring, metal coated pad (Pad ladle) PTFE pad, copper pads, tooth pads, octagonal pads, lens pad, Kevlar oil and rubber mats. Packing categories: graphite packing PTFE packing Aramid packing carbon packing high water based packing. PTFE categories: PTFE sheet, PTFE rod, PTFE elastic belt, PTFE soft stick wound pad special PTFE tape and other products. Spiral wound gasket is widely used in the petrochemical, oil refining, power, steel, shipbuilding, marine engineering, the industry not only solve many domestic power plants, gas plants, chemical plants, pumps, valves, pipes in various gas / chemical fluid transport in seal leakage, which has been designated for many well-known enterprises and selection and has been exported to Europe, the Middle East, South America and Southeast Asia and many other countries and regions. The company has advanced production and testing equipment, experienced, well-trained staff: Adequate inventory of raw materials and products to customers in a timely manner to provide sealing products provide protection to all products on the domestic and international industry standards such as GB, ASME-ANSIDINJIS , BS, ASTM and other norms manufacturing. And to develop various kinds of special specifications of seal products.
