External Thread Directy

PPR pipe with the traditional cast iron pipe, galvanized steel pipe, cement pipe, such as the energy-saving materials, environmental protection, light weight, high strength, corrosion resistance, smooth inner wall size, simple construction and maintenance, long life and other advantages, is widely used in building water supply and drainage, urban and rural water supply, drainage, city gas, agriculture, construction, industry and agriculture and other fields. 1:Anti-freeze cracking: the good elasticity of PP-R material enables the pipe and pipe section to expand together with the frozen swelling liquid without cracking. 2:Recyclable: PP-R pipes and fittings can be recycled and reused. 3:Long service life: the service life of the piping system under specified service conditions is up to 50 years 4:Anti-wear and no scaling: the inner wall of PP-R pipe and pipe fitting is uniformly smooth, with small flow resistance and no scaling.
