PVC pipes and fittings according to DIN 8061 - 8062 are used in the discharge of municipal, sanitary and rainwater. Pipes and fittings of this category are provided for underground water installations and generally for water transport with or without pressure. The joint is made with glass and adhesive material. Simple and fast coupling reduces assembly costs and ensures full leakage at the coupling sites. It is not deformed and damaged due to its chemical resistance, in most cases acids, salts etc. It is transported and mounted easily and quickly due to its low weight. and of the chemical composition of their material. They have very high mechanical resistance to superconductors (hydraulic punches). They have very long service life.
