Product Description

Product Description

 

Reinforced Graphite composite Sheet( With Stainless Steel)

Graphite composite gaskets, also known as reinforced graphite gaskets or high-strength graphite gaskets, are made by punching or cutting reinforced graphite plates. They have good corrosion resistance, high/low-temperature resistance, good compression resilience, and high strength.

Material:

The commonly used inner layer reinforcement materials for reinforced graphite gaskets include SS304, SS316, or sheet iron, with a thickness of 0.1-0.127mm. They come in the form of punching plate reinforcement, mesh plate reinforcement, and flat plate reinforcement. The commonly used material is 304-reinforced graphite.

 

Product Parameters

 

High-strength graphite gaskets can be processed into the following forms according to usage needs:

1. Basic graphite composite gasket

2. Graphite composite gasket inside the package

3. Wrap the outer graphite composite gasket

4. Graphite composite gasket with inner and outer edges.

 

The edge wrapping form of graphite composite gasket not only maintains the excellent performance of the original gasket, but also facilitates installation and disassembly, is not easily damaged, and can prevent medium erosion of the gasket, improving pressure resistance. The commonly used edging material is 304 or 316 stainless steel.

Our Advantages

 

Application

Various circular geometric gaskets can be made and are widely used in pipelines, valves, pumps, pressure vessels, heat exchangers, condensers, generators, air compressors, exhaust pipes, refrigerators, etc.

Graphite-reinforced gaskets can also be cut into complex-shaped gaskets, such as water-level gauge gaskets, punched flange gaskets, and cylinder gaskets for automotive diesel engines.
