The use range of butt welded flanges is relatively broad, and the requirements for installation will also be relatively high. The following also introduces the installation sequence and precautions for butt welded flanges
The first step is to organize the inner and outer sides of the connected stainless steel butt welded pipe fittings before connecting the welding flange.
The second step is to install the flange plates with groove rings on the pipes that need to be connected.
Then, the port of the pipe needs to be processed with a 90 degree flanging process, and the plane of the processed pipe port needs to be polished. After polishing, it should be vertical and flat, and there should be no burrs, concavities, or deformations, and the pipe mouth needs to be rounded with special tools.
In fact, there is also a simple method of using finished products to flange short pipes and then welding them onto the pipes.
Next, insert the O-ring and stainless steel sealing ring installed on both sides into the flange with groove ring. The inner hole of the sealing ring is the same as the inner diameter of the pipe.
Then connect the flange holes with bolts, and tighten the bolt components symmetrically.
Finally, when tightening the butt welding flange, it is important to ensure that all joints are tightened to the required specifications.
