The PP flange is a part that connects the pipe to the pipe and is connected to the pipe end. In plumbing, flanges are primarily used for pipe connections. Different pressure flanges have different thicknesses, the number of screw holes and screw hole sizes are different, and different bolts are used. PP flanges, generally 1.0MPA pressure, the number and size of bolts, refer to HG20539-92 standard. When the water pump and the valve are connected to the pipeline, parts of these equipments are also made into corresponding flange shapes for easy connection, called flange connection. There are holes in the flange, and the bolts make the two flanges tightly connected.
PP flange classification:
Flat flange (socket flange, flange), with neck flange (butt weld flange), backing ring (flange, flange adapter), blind plate (blind flange, blocking plate).
PP flange application:
PP flanges generally refer to the opening of several fixed holes in the periphery of a disk-like plastic body for joining other things. This thing is widely used in pipes and machinery, so the flange is a disc-shaped part. It is more common in pipeline engineering, and flanges are used in pairs.
The PP flange is an accessory that connects the pipe to the pipe and is connected to the pipe end, also called a flange. Insert the pipe into the flange during installation and use a welding torch to melt the electrode to the seal joint. This type of welding is a socket type connection, and the advantage is quick and convenient. The disadvantage is that improper handling of the connector may easily open if subjected to external forces.
