Generally, the type of steel pipe is larger than that of ppr pipe. Generally, pipe 16 corresponds to ppr20, steel pipe 20 corresponds to ppr25, and steel pipe 25 corresponds to ppr32.
Pipe fittings can be divided into four types according to the connection method: socket pipe fittings, threaded pipe fittings, flange pipe fittings and welded pipe fittings. It is made of the same material as the pipe. There are elbow (elbow), flange, tee, cross pipe (cross head) and reducer (size head).
The elbow is used to rotate the pipe; the flange is used to connect the pipe and the pipe to the end of the pipe, the tee is used to collect three pipes; the four-way pipe is used to collect four pipes; the diameter pipe is used to connect two different pipe diameters Pipeline.
The green PPR pipe fittings are called three-type polypropylene pipe fittings, which are extruded into pipes by random copolymerization of polypropylene and injection molded into pipe fittings; PPR is a gas phase copolymerization process that randomly polymerizes about 5% in the PP (random copolymerization) molecular chain PE has become a new generation of pipes. It has good impact resistance and long-term creep properties.
