Spiral Wound Gasket

详情

Spiral Wound Gasket  -  WFY****0:
===========================
CONSTRUCTION:
WFY SW***0 Spiral-Wound gasket is formed of V-shaped metallic stripe and soft non-metallic filler by means of piled, spiral wound and connected its and beginning by dot welded. Depend on its excellent compression resilience it is suitable for sealing spots where the alteration of temperature and pressure ae frequent. It can be used as the static sealing element of pipe, valve, pump, thermal exchange, condensing tower, plain hole and man hole of flange, etc. It has been widely applied in the fields of petrochemical , mechanical manufactory, power station, metallurgry, shipbuilding, medical and pharmaceutical nuclear power station and navigation, etc.
=======================================================

Metallic flake and filling material role:

Spiral wound gaskets metal and packing by alternating winding and become, section a "V" shaped, has the extremely compressed recovery
****************************************************************************-

Outer ring role:

Install gaskets, has focused on the correct position will shim the function

Reinforcement/protection gaskets block

Prevent locked up for gaskets greatly too forcibly damage (prevent spin twist overtighten)

*****************************************************************************-

Circuit.and the role:

Internal fluid pressure, temperature is high

Internal fluid causing corrosion and erosion

Should avoid internal fluid residue YuFaLan when the space between

Packing materials for ptfe, graphite (prevent gaskets of clamping force when dimension to block deformation) pads
