Overview
Metal wound gasket is a widely used sealing gasket, which is the most elastic gasket among semi metal sealing gaskets. The wound gasket is made of high-quality SUS304, SUS316 "V" - or "W" - shaped metal strips and other alloy materials such as graphite, asbestos, polytetrafluoroethylene, asbestos free and other soft materials that alternate and overlap each other in a spiral winding manner. Depending on its formula, process, performance, and usage,
Product Details
Mechanical seal gasket, metal wrapped gasket
Metal wrapped gasketTypes of:
（1） Basic metal wrap pad
（2） Metal wrapped pad with outer ring
（3） Metal wrapped pad with inner ring
（4） Metal wrapped pads with inner and outer rings
（5） For heat exchangers (with ribs)
（6） Alien metal winding pad
Metal wrapped gasket(Basic type) Using high-quality SUS304, SUS316 "V" - or "W" - shaped metal strips and other alloy materials with asbestos, flexible graphite, polytetrafluoroethylene, non asbestos fibers[1]Soft materials are overlapped and spiral wound together, and the metal strip is fixed by spot welding at the beginning and end.
1. Metal strip material
A. Cold rolled steel strips such as 08F, 0Cr13, 0Cr18Ni19Ti, 0Cr18Ni9Ti, 00Cr18Ni10, 0Cr18Ni12Mo2Ti, 00Cr17Ni14Mo2201304316 with a thickness of 0.15mm~0.25mm shall be used, or determined through negotiation between the supply and demand parties.
B. The metal strip should be a pre formed V-shaped or W-shaped narrow strip with a smooth surface Clean, there should be no roughness or unevenness crackle. Scratches Defects such as dents and rust spots
C. The hardness value of stainless steel HV ≤ 200
D. The width of a typical steel strip is 3.2mm, 4.5mm, 8mm, and W-shaped steel strips can be thicker.
E. Stainless steel strip shape: "V", "W", "SUS", "U".
Stainless steel strip material: A3304304L, 316316L, Monel, titanium Ta.
2. Non metallic strip materials
A non-metallic filling includes specially made asbestos tape, flexible graphite tape, polytetrafluoroethylene tape, non asbestos fiber tape, ceramic fiber and mica tape, etc. The thickness of the tape is 0.3-1.0mm.
B. The burning loss of special asbestos must be ≤ 25%
C. The chloride ion content of non-metallic strips is ≤ 100PPM
D. Recommended operating temperatures and pressures for various media and non-metallic tapes
E. The width of a typical steel strip is 3.2mm, 4.5mm, and 8mm
F. Suitable temperature: -196 ℃+870 ℃ (flexible graphite)
≤+250 ℃ (PTFE)
≤+500 ℃ (special asbestos)
3. Inner and outer ring materials
Commonly used materials include 304SS, 316LSS, 321SS, 347SS, carbon steel, titanium, and copper
