Product Description

Expanded Graphite Filled Spiral Wound Gasket

This is a spiral wound gasket that uses expanded graphite in the filler strip. It has excellent sealing performance even under severe conditions such as high temperature and high pressure, low temperature, thermal cycle, and temperature cycle.

Features:

1. Compared with non-asbestos gaskets, the sealing performance is better (especially the air-tightness)
2. The filler strip is not easy to age at high temperature, and it can have excellent sealing performance for a long time even under high temperature and high pressure conditions.
3. It can have excellent sealing performance even under harsh conditions of pressure changes and high and low temperature cycles.
4. It has excellent corrosion resistance, so as long as the appropriate metal strip material is selected, it can be used for various corrosive fluids that cannot use asbestos gaskets.
5. Excellent sealing performance under low temperature conditions.

Applications:

Suitable for flanges of various industrial pipelines, pressure vessels, heat exchangers, valve covers, etc., especially used as gaskets in high-temperature and high-pressure steam, low-temperature applications such as LNG.

Unusable scenarios:
Classification	Fluid Name
strong acid	Nitric acid, concentrated sulfuric acid, hot sulfuric acid, chromic acid, mixed acid, etc.
Easily oxidizable salt	Nitrate, chlorate, hypochlorite, etc.
Halogen compounds	Bromine, fluorine, iodine, chlorine dioxide, etc.
Combustion-supporting gas	Oxygen (pure oxygen)

Scope of use:
Fluid	Maximum working temperature	Maximum working pressure
Water-like fluid	450 (650)	class 2500
Oil fluid	450 (800)	class 1500
Gaseous fluid	450 (800)	class 1500
Cryogenic fluid	-240 (minimum working temperature)	20MPa
Note 1. ( ) Inside the brackets indicates the maximum working temperature when not used in oxidizing systems. The maximum temperature for raised face flanges in atmospheric environments is 450°C.
Note 2. The maximum working temperature varies depending on the type of metal strip and inner and outer ring materials. Do not apply gasket adhesive.
