SPIRAL WOUND GASKET

Spiral Wound Gasket

The spiral wound gasket was developed in the early 20th century to meet the increasingly demanding conditions encountered in oil refinery operations. This type of gasket is commonly used with flange surface finishes.Gaskets used in the gas,oil and petroleum industries need to be engineered to cope with high pressures, extreme temperatures and chemical attack. Fluctuations in the above, along with temperature differential across the flange face and bolt stress relaxation, demand a gasket with flexibility and recovery. The need for the gasket to recover from changing conditions cannot be over emphasized.

SPIRAL WOUND GASKET SUPPLIER FROM CHINA FOR OIL AND GAS INDUSTRY

Spiral Wound Gasket Construction

The spiral wound gasket is semi-metallic, comprising of a spirally wound v shaped stainless steel strip and a non-metallic filler material, such as graphite or PTFE. On the gasket, there is a solid outer ring used for centering and controlling compression. This minimizes the risk of material creep through over-tightening.For the toughest conditions, spiral wound gaskets are available with an additional inner ring. This protects the winding , from contamination, or attack by the product travelling past the pipeline joint.

Application of Spiral Wound Gasket

Spiral wound gaskets are particularly suitable for complex equipment in the petroleum, chemical and gas, industrial and marine industries. They can be used in water, steam, oil, solvents and other common industrial chemicals. Its excellent resistance to high temperatures and pressures mean it is ideal for pipe line flanges, heat exchanger, valve bonnets, boiler manholes, hand holes and tube caps. Our spiral wound gaskets can be tailor-made with almost any combination of metal or non-metal materials.
