How much do you know about the correct installation process of butt welding flanges?
The correct installation sequence of the butt welding flange: first, before connecting the butt welding flange, the inner and outer sides of the connected stainless steel pipe fittings should be checked. Separately install the flange with grooved ring on the pipe to be connected. The port of the pipe needs to be processed by a 90-degree flanging process. After the treatment, the port plane of the pipe needs to be ground. After grinding, it should be straight and flat, and there is no doubt about burrs, bumps and deformation, and the nozzle needs to be rounded with a special tool.
Another simple way is to use the product to flange the short pipe and then weld it on the pipe. Embed the O-ring rubber sealing ring stainless steel sealing ring installed on both sides in the flange with grooved ring. The inner hole of the sealing ring is the same as the inner diameter of the pipe, and then the flange holes are connected with bolts, and the bolt components need to be tightened symmetrically. When tightening the butt welding flange, attention should be paid to the tightness of each joint to meet the required specifications.
Butt welding flange is a kind of pipe fitting, which refers to the flange with neck and round pipe transition and connected with pipe butt welding. The butt welding flange is not easy to deform, well sealed and used, suitable for pipelines with greatly unstable pressure or temperature or high temperature, high pressure and low temperature pipelines. The advantage is that the quotation is relatively cheap, and the nominal pressure does not exceed 2.5MPa; it is also used for transportation quotations On the pipeline of precious, flammable and explosive medium, the nominal pressure is about PN16MPa.
