Spiral Wound Gasket Filled With Main Applications
Excellent elastic recovery of metal spiral wound gaskets can pressure thermal cycling and vibration of piping system
Automatic adjustment, especially for uneven load, engaging force relaxation and cyclic variation of temperature and pressure, a shock or vibration occasions. Valves, pumps, heat exchangers, towers, manholes, hand holes static sealing of flange joints such as original, widely used in petrochemical, machinery, electric power, metallurgy, shipbuilding, medicine, Atomic Energy and aerospace sectors.
Flange cushion design for ease of installation, according to gasket size in the gasket on the perimeter weld 2~8 positioning, positioning the buckle on the hole in the flange to prevent install gasket when shifting or shedding, auxiliary materials and conservation work. is generally divided into the following types:
Spiral wound gasket filled with high quality SUS304, SUS316 ("v" or "w" shaped) metal belt and other metal materials and graphite, asbestos, PTFE gasket, non-asbestos and other soft materials alternating overlapping spiral-wound, and at the beginning and end of spot weld the metal band. Spiral wound gasket filled with elastic back for half a metal seal gasket best gasket, metal spiral wound gaskets density can be produced according to the locking force requirements to, and using the inner and outer steel ring to control the maximum pressure tightness, spiral wound gasket flange seal surface of contact surface accuracy requirements are not high. Spiral wound gasket applied to uneven load, engaging force relaxation and cyclic variation of temperature and pressure, a shock or vibration occasions. Spiral wound gaskets are valves, pumps, heat exchangers, towers, manholes, hand hole original flange connection suitable for static sealing.
