How do PPR and flange bond
The Flange is also called a Flange or Flange dish. The flange is the part of the pipe that connects the pipe to the pipe. Flange connection or flange connection, it is to point to by the flanges, gaskets and bolts are mutually connected as a set of sealing structure detachable connection, pipe flange refers to the plumbing for piping flange, used in equipment refers to the import and export of the flange of the equipment. There are holes in the flanges, and bolts make two flanges. The flange is sealed with gasket. Flange threaded connection (wire) flange and welding flange.
The material of the flange. In the PPR pipe flange is mainly composed of PVC materials, mainly used for PPR pipe joint gasket flange (flange, be) by a flange, a gasket and a number of bolt and nut. The gasket in between the two flange sealing surface and tighten nut, washer on the surface of a pressure deformation after reaching a certain value, fill and seal surface uneven, not connected closely. Flange connection is a removable connection. The connected parts can be divided into container flanges and tubes; According to the structural type, there are integral flange, living flange and threaded flange. The common flange has flat welding flange and welding flange. The stiffness of flat welding flanges is poor, applied to the situation of pressure p is not equal to 4MPa. The welding flange is also known as the high neck flange, which is rigid and applied to high pressure temperature
There are PPR loose flanges, PPR tube preheated fusion welding.
The hot melt and welding method can be done, but the strength of the fusion will be better.
