what we supply 

M/FM-concave convex sealing surface

The two sealing faces, Male Face and Female Face, are a pair, one female and one male, and must be used together. It is easy to align when installed and prevents the gasket from being squeezed out. Suitable for occasions with high pressure.

Sealing gaskets suitable for concave-convex sealing surfaces include: various non-metallic flat gaskets, coated gaskets; metal-clad gaskets; basic or inner ring-shaped winding dies.
T/G-Tongue groove connection sealing surface

Tongue Face and Groove Face are similar to the concave and convex surface, and are also a male and female matching sealing surface type. They are also used in pairs. The gasket is located in the annular groove, which is limited by the metal walls on both sides. It can prevent the gasket from being compressed and deformed into the pipeline. Because the gasket is not in direct contact with the fluid medium in the pipe, it is less eroded or corroded by the fluid medium, so it can be used in high pressure, flammable, explosive, and toxic media where strict sealing requirements are required. This kind of sealing surface gasket is good for installation, but the sealing surface is more difficult to process. It is easy to damage the sealing surface when replacing the gasket, and the flange must be separated in the axial direction during installation and disassembly. Therefore, consideration should be given to the pipeline design It is possible to separate the flange in the axial direction.

The gaskets suitable for the sealing surface of the tongue and groove surface are: various metal and non-metal flat gaskets, metal clad gaskets and basic spiral wound gaskets.

RF-raised face

The Raised Face type sealing surface is the most widely used among several types. The most commonly used one is the international standard, the European system and the domestic standard are all fixed height, but the American standard flange should pay attention to the height of high pressure will increase the sealing surface The height, the use of gaskets also have many types.

The gaskets suitable for flanges with raised sealing surfaces include various non-metallic flat gaskets and coated gaskets; metal-clad gaskets; wound gaskets (including outer rings or inner and outer rings), etc.
