Product Description
Haokun's series of Socket Welding flange refers to the flange that the pipe end is inserted into the flange ring ladder and welded at the pipe end and outside. There are two kinds of neck. The flange with neck has good rigidity, small welding deformation and good sealing. It can be used in the pressure range of 1.0 ~ 10.0MPa. The type B flange for vessels is also a socket welding flange, which is used in occasions with high sealing requirements.Similar to a slip-on flange in design, but with a bore that is counter-bored to accept pipe. The diameter of the remaining bore is the same as the inside diameter of the pipe. A fillet weld around the hub of the flange attached the flange to the pipe. An optional interval weld may be applied in high stress applications. Its biggest use is in high pressure systems such as hydraulic and steam lines.
