AS2129 AS4087 Flanges Manufacturer in JiangSu, China

Short Description:

A threaded flange is a type of flange that is threaded to the pipe. Designed with a loose flange. The advantage is that no welding is required and the additional torque generated on the cylinder or pipe when the flange is deformed is small. The disadvantage is that the flange is thick and the cost is high. Suitable for connection to high pressure pipes.
