Quality appraisal of PPR pipe production equipment

PPR pipe, officially called random copolymer polypropylene pipe, is currently the most commonly used water supply pipe in home improvement projects. Hot-melt connection technology is used during construction to achieve seamless welding and avoid the risk of water leakage, replacing aluminum-plastic pipe materials that are prone to aging and leakage with ferrule-type joints. It has the advantages of energy saving and material saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall and no scaling, easy construction and maintenance, and long service life.

PPR pipe is widely used in building water supply and drainage, urban and rural water supply and drainage, urban gas, electric power and optical cable sheathing, industrial fluid transportation, agricultural irrigation and other construction, municipal, industrial and agricultural fields.
