Metallic Gasket WrapAs a sealing gasket for static seals, widely used,
Its features include easy installation, high-temperature resistance, high-pressure resistance, corrosion resistance, and oil resistance.
How to Choose a Gasket: Mainly Based on the Flange, as the Gasket is Designed to Fit the Flange.
Firstly, the standard is crucial. The flange standard is ANSI for American standards; the gasket should be selected accordingly. For Chinese standards, choose the Chinese standard gasket. It's important to select the correct standard, as choosing the wrong one can cause trouble during installation. The size of the gasket varies with different standards. Next, consider the sealing surface: for RF, choose the inner and outer rings; for MFM, select the one with the inner ring.
TG chose the basic model, while FF selected the outer ring model.
Additionally, for gasket materials, if there are corrosive substances inside the pipeline, the inner ring should be made of corrosion-resistant materials such as 304, 316L, etc.
For high corrosiveness or high temperatures, select special materials such as titanium alloys, Inconel, and Monel.
If the sealing is not involved in the outer ring, and the conditions are generally standard, galvanized carbon steel would suffice. The choice mainly depends on the owner's design and usage requirements.
