Weld Neck Flanges

These are mainly used for thermal coupling of pipes in the most difficult cases, that is, bending stresses at the coupling are expected due to cross-sectional expansion or other forces.

Slip-on flanges

These are used for fast assembly to save costs and the requirements for the length of the pipe section are not so strict.

Socket welding flanges

It is recommended for orifice flanges and can replace slip-on flanges when the pipe diameter is very small and the working pressure is very high.

Lap joint flanges

It is mainly used in cases where fast assembly and disassembly of pipe sections is required under limited working pressure.

Threaded Flanges

These flanges are used in special environments, working under high temperature and high pressure, ensuring no welded joints during assembly.
