Supply of internal and external reinforced graphite wrapped gaskets

Internally and externally reinforced graphite wrapped gasketsWrapped with stainless steel strip and flexible graphite strip, welded to form. The main purpose of metal graphite wrapped gaskets is to seal pipelines, valves, pump inlets and outlets, various heat exchangers, reaction towers, observation holes, handholes, and other parts that come into contact with steam, oil and gas, solvents, gases, heat transfer media, etc. Temperature for use of metal graphite wrapped gaskets; -200 ℃ to 650 ℃. Types and specifications of metal graphite wrapped gaskets: basic types, with inner ring, with outer ring, with inner and outer rings, special-shaped and other specifications. Size, thickness 3.2, 4.5mm. nominal diameter, ￠ 10- ￠ 2000mm

Internally and externally reinforced graphite wrapped gaskets

1、 Internally and externally reinforced graphite wrapped gasket structure
The spiral wound gasket is formed by overlapping a "V" - shaped (or "W" - shaped) metal strip and a non-metal strip, and continuously winding them. The metal strip is fixed at the beginning and end by spot welding.

2、 Performance and Characteristics
1. The applicable operating range is wide. Capable of withstanding high temperatures, high pressures, and adapting to usage conditions under ultra-low temperatures or vacuum. By changing the material combination of the gasket, the chemical corrosion problem of various media on the gasket can be solved.
2. Strong stress compensation capability. At workstations with frequent temperature and pressure fluctuations, the sealing performance is stable and reliable.
3. Excellent sealing performance.
4. The surface accuracy requirement for flange sealing in contact with gaskets is not high.
5. Easy to install, with low pre tightening pressure on the gasket.

3、 Types of gaskets
1 A、 There are four forms of wrapped gasket: basic type, with inner ring type, with outer ring type, and with inner and outer ring type.
B、 Spiral wound gaskets for heat exchangers are generally divided into basic types and types with inner and outer rings.
2. Commonly used materials:
A、 钢带： 08F、0Cr18Ni9（304）、0Cr18Ni9Ti、1Cr18Ni9Ti（321）、0Cr17Ni12、M02（316）、00Cr17Ni14M02（316L）
B、 Cold rolled steel for inner and outer rings
