Description

Spiral wound gaskets are special semi-metallic gaskets of great strength and resilience. Manufactured by spirally winding V-shaped metal strips and strips of non-metallic filler with good sealing characteristics, they are suitable for use under heavy operating conditions at high temperature and pressures. Applications include the sealing of flange joints, boilers, heat exchangers, valves and pressure vessels. Inner rings and outer rings may be added to reinforced the gasket. A range of metals and filler materials are available to suit different applications.

Spiral wound gaskets are special semi-metallic gaskets of great strength and resilience. Manufactured by spirally winding V-shaped metal strips and strips of non-metallic filler with good sealing characteristics, they are suitable for use under heavy operating conditions at high temperature and pressures. Applications include the sealing of flange joints, boilers, heat exchangers, valves and pressure vessels. Inner rings and outer rings may be added to reinforced the gasket. A range of metals and filler materials are available to suit different applications. Standard Tesitallic spiral wound gaskets are made to fit ANSI B 16.5 and BS 1560 flanges. Spiral wound conforming to ASME B16.20 specification on request. Colour coding to industry standard is available. Nominal thickness available is 4.5mm and 3.2mm. Special request is required for a nominal thickness of 6.4mm. Non standard spiral wound gaskets are available in various dimension and shapes for use as flange gasket, manhole gasket, handhole gasket or other applications. Spiral wound gaskets is only suitable for circular or moderately non-circular shapes.Limitations on size and shape largely depends on practical considerations in the manufacture of the gasket.
