Polypropylene PP pipes are produced according to the QB1929-93 standard, with specifications De20-De800mm and nominal pressure 0.4-1.6MPa. Polypropylene PP pipes are suitable for fields such as municipal water supply and drainage, agricultural irrigation, and corrosive liquid transportation (e.g., chemical and pharmaceutical industries).

1  Engineering Polyethylene pp pipe Standards
◇  PP pipes comply with the QB 1929-93 standard.
◇  PP pipes are produced using copolymer-grade PP polypropylene raw materials specifically for pipes, suitable for general-purpose pressure water conveyance and drinking water transportation.
◇  The hygienic performance of PP pipes for drinking water complies with GB/T17219 regulations.
2  Engineering Polyethylene pp pipe Features
◇  Rust-free: PP pipes can withstand pH values over a wide temperature range and resist corrosion from high concentrations of acids and alkalis ranging from 1 to 14.
◇  Wear-resistant and scale-free: The inner walls of PP pipes and fittings are uniformly smooth, offering low flow resistance and no scaling.
◇  Vibration and noise reduction: PP pipes possess excellent sound insulation performance, significantly reducing vibration and noise caused by liquid flow.
◇  Freeze-crack resistance: The excellent elasticity of PP material allows the cross-section of pipes and fittings to expand along with the freezing liquid without bursting.
◇  Anti-condensation and low heat loss: PP material is a poor thermal conductor, reducing condensation phenomena and minimizing heat loss.
◇  Simple installation: PP pipes are lightweight, easy to install and operate, and weldable.
◇  Long service life: The PP pipe system has a service life of up to 50 years under specified usage conditions.
