Dn100 Cl150 Astm A182 304L weld neck flange raised face forged flange
Flange, also known as flange plate or flange. Flange is a part connected between shafts, which is used for the connection between pipe ends; The flange on the equipment inlet and outlet is also used for the connection between two equipment, such as reducer flange. Pipe flange refers to the flange used for piping in the pipeline device, and the flange used on the equipment refers to the inlet and outlet flange of the equipment. The flange is divided into threaded connection (threaded connection) flange, welding flange and clamp flange. Flanges are used in pairs. Threaded flanges can be used for low-pressure pipelines, and welded flanges can be used for pressures above 4kg.
Butt welding flange with neck refers to a flange with cone neck and butt welded with cylinder or pipeline. It is an integral flange. Due to the transition structure of cone neck and butt welding connection, the strength and stiffness of flange are strengthened, and the tightness is better than that of flat welded flange. The disadvantage is that it consumes a lot of materials and has a high manufacturing cost. It is suitable for occasions with high pressure and temperature or high sealing requirements.
It is made of stainless steel and carbon steel.
