Spiral wound gasket has many excellent sealing performance.
- Mar 06, 2018 -

Spiral wound gasket has many excellent sealing performance, such as: thermal stability, self-lubricating, corrosion resistance, no aging, not brittle, in harsh conditions can be long-term stable use, very few need to maintain.

Spiral wound gasket (basic type) is the use of standard quality SUS304, SUS316 ("V" or "W") metal bands and other alloy materials with graphite, asbestos, PTFE, asbestos and other flexible materials overlapping spiral winding, and at the beginning and the end of a spot welding method to the metal belt fixed.

Performance: High temperature, high pressure, corrosion resistance, with good compression rate and rebound rate.

Applications: pipes, valves, pumps, manhole, pressure vessels and the like of the flange joints of petroleum, chemical, electric power, metallurgy, shipbuilding, papermaking, medicine, etc.

The sealing part of heat exchanging equipment is the ideal static sealing material.

Stainless steel with shape: "V" "W" "SUS" "U".

Stainless steel belt Material: A3, 304,304l,316,316l, Monel monel, Titanium ta.

Non-metal tape (filler): Special asbestos, asbestos-free, flexible graphite, PTFE and so on.

Adaptation temperature: -196--+870 (Flexible graphite)

≤+250 (PTFE)

≤+500 (Special Asbestos)

Medium: Suitable for high-temperature high-pressure vapor, oil, oil and gas, solvents, hot coal body oil.

Use pressure: ≤300mpa

Maximum processing size: 2800 mm; special specifications or various non-standard products can be produced according to your requirements.

Minimum preload pressure: Y=68mpa

Structure:

The inner Loop Metal wound gasket is composed of a basic type and an inner ring made of 304,304l,316,316l,321,ta Mon400 Inconel, which is used to strengthen the pressure.

Equipment:

Pipe, valve, pump, pressure vessel, condenser, tower, manhole, hand hole, such as the flange connection of the static sealing material.

Industry:

Spiral wound gasket  with inner ring can be used in petrochemical, machinery, electric power, metallurgy, shipbuilding, medicine, atomic energy and aerospace industries.

Medium: Suitable for high-temperature high-pressure vapor, oil, oil and gas, solvents, hot coal body oil.
