What are the plastic pipes that can be welded?
What plastic material can be welded? What's the question? - ah, a little dizzy, not plastic. What is it? Generally weldable plastic pipes are PPR tubes and PE pipes.
General PP, PE pipe can be used hot melt welding, using PVC glue adhesive.
PE is the most basic plastic of polyethylene plastics, plastic bags, plastic film and so on are PE, HDPE is a high crystallinity, non-polar thermoplastic resin. The appearance of the native HDPE is milky white and is somewhat translucent in the narrow cross section. PE has excellent properties that are resistant to most life and industrial chemicals.
1, general welding of plastic pipe is PPR pipe, PE pipe.2, PP-R (polypropylene random) tube called type three polypropylene pipe and is also called the PP-R pipe or PPR pipe, with energy saving, environmental protection, high strength, corrosion resistance, with smooth inner wall has the advantages of scale, construction and easy maintenance, long service life, widely used in building water supply and drainage, urban and rural areas city water supply and drainage, gas, electricity and cable sheath, industrial fluid transportation, agricultural irrigation construction, municipal, industrial and agricultural fields. The PP-R pipe is made of random copolymerized polypropylene and is extruded into tubes to be molded into tubes.
