What is ppr pipes and fittings?

In the industrial manufacturing field, especially in industries such as chemical processing, food, pharmaceuticals, electronics, and mechanical manufacturing, these pipes also play an important role. They are particularly suitable for industrial piping systems with high requirements for water purity, corrosion resistance, and system stability. PPR pipes, made of polypropylene, are therefore highly suitable for use in the above-mentioned industrial environments.

What Is PPR Pipes and Fittings?

PPR pipes and fittings, also known as polypropylene random copolymer pipes, are a type of plastic pipe used in hot and cold water supply and heating systems.

PPR pipes are high-performance plastic pipes made primarily from random copolymer polypropylene (PPR) through an extrusion molding process. They feature safety, heat resistance, pressure resistance, non-toxicity, and corrosion resistance, and are mainly used for the transportation of drinking water and domestic hot water. PPR pipes are widely applied in modern building water supply systems.

PPR is a high-performance pipe-grade material obtained by copolymer modification of polypropylene (PP). It is suitable for a wide range of residential and industrial applications, including hot and cold water supply systems in buildings, drinking water distribution systems, and the conveyance of non-corrosive fluids such as weak acids and weak alkalis in industrial applications.

Main Features of PPR Pipes

PPR is made of polypropylene random copolymer, which significantly improves its heat resistance and impact strength compared to PP pipes.

Excellent heat resistance

Long-term operating temperature up to 70°C

Short-term temperature resistance up to 95°C

Stable pressure resistance

Suitable for the long-term pressure requirements of building water supply systems

Hygienic and non-toxic

Does not release harmful substances and is suitable for drinking water transportation

Corrosion-resistant and scale-free

Does not rust or form scale, ensuring cleaner water quality

Heat fusion connection with reliable sealing

Pipes and fittings are fused into an integral system, virtually eliminating the risk of leakage

Main Functions of PPR Pipes

◆ Safe conveyance of hot and cold water

◆ Ensuring drinking water hygiene

◆ Withstanding long-term temperature and pressure variations

◆ Providing a stable and durable piping system solution

◆ Reducing maintenance and replacement costs

Comparison of PP and PPR Pipes

There are significant differences in material structure and performance between PP pipes and PPR pipes. The following is a detailed comparative analysis.

Key Points for Using PPR Pipe Fittings

◆ Fitting material must match the pipe material

◆ PPR pipe fittings should be made from the same grade of PPR material as the pipe.

◆ The melting temperature, thermal expansion coefficient, and pressure rating of the pipe and fittings must be consistent.

◆ Do not use other plastic fittings such as PP or PVC as a substitute.
