PP-R Cold & Hot Water Pipe Fittings

PP-R hot and cold water pipe fittings are injection molded from high-quality random copolymerized polypropylene. They have the same material and performance matching as PP-R pipes. They are specially designed for use in building water supply, HVAC and conventional industrial fluid delivery systems. The product is heat-resistant, corrosion-resistant, has excellent hygiene, the material is pure and non-toxic, and no harmful substances are precipitated. It complies with civil drinking water standards and is suitable for various clean water delivery scenarios.

This series includes all types of pipe fittings such as elbows, tees, direct, variable diameter, internal and external wire joints, flanges, plugs, etc., with complete specifications and strong versatility. The inner wall of the pipe is smooth and has low fluid resistance. It will not scale or breed bacteria after long-term use, effectively ensuring water quality and efficiency. The product can withstand hot and cold water media of 70℃ for a long time and high temperature of 95℃ for a short time. It is suitable for various pipeline connection scenarios such as domestic hot and cold water supply, heating system, central air conditioning water circulation and so on.

The accessories adopt hot-melt connection technology and can be integrated with PP-R pipes of the same specifications. The interface is dense and firm, has good sealing performance, and is stronger than the pipe body, fundamentally eliminating leakage and shedding problems. The product is anti-aging, corrosion-resistant, and maintenance-free. The service life of the entire system can reach more than 50 years. It also has the advantages of light weight, easy installation, efficient construction, impact resistance, and green environmental protection.

With stable comprehensive performance, PP-R hot and cold water pipe fittings are widely used in hot and cold water supply, heating circulation, and pure water transportation projects in residences, hotels, hospitals, schools, factories, and various public buildings. They are safe, energy-saving, and durable core supporting pipe fittings for modern building water supply and drainage systems.

Performance
  • Excellent high temperature resistance, suitable for hot and cold water supply systems

    Made of random copolymer polypropylene, it is suitable for alternating hot and cold water supply conditions. The long-term hot water use temperature is 70°C, and the instantaneous high temperature resistance can reach 95°C. It is suitable for both hot and cold uses; it complies with GB/T 18742, ISO 15874, DIN 8077, DIN 8078, and ASTM F2389 standards.

  • Hygienic, safe and non-toxic, can be used for direct drinking water transportation

    Injection molded using food-grade PP‑R raw materials, it has no heavy metals, no harmful substances precipitated, and does not breed bacteria. It can be used for direct drinking water transportation to ensure water safety; it complies with GB 4806.7, NSF/ANSI 61, and KTW health standards.

  • Good thermal insulation performance, energy saving and consumption reduction

    The thermal conductivity of the material is low. The use of pipe fittings and pipes can greatly reduce heat loss in hot water transportation, reduce energy consumption, effectively avoid condensation and dripping problems at pipeline nodes, and have excellent energy-saving effects.

  • Corrosion-resistant and non-scaling, long-term stable water quality

    Resistant to acid and alkali, scale and microbial corrosion, the inner wall of the accessories is smooth, the water flow resistance is small, it is not easy to scale or shrink after long-term use, and the water quality and water flow are continuously stable; it complies with ISO 4433, EN 12573, and DIN 50929 standards.

  • The hot-melt connection is integrated and has zero leakage and no water leakage.

    It adopts standard hot-melt socket connection, and the pipe fittings and pipes are integrally welded and formed. The interface strength is higher than the pipe body, and the sealing is extremely strong, completely eliminating the risk of leakage; it complies with DVS 2207, EN 12814, and DIN 16928 process standards.

  • High toughness, impact resistance and water hammer resistance

    The accessories have sufficient toughness and strong impact resistance, can withstand water pressure fluctuations and water hammer damage, have excellent low-temperature toughness, can be used in normal construction at -20°C, and are not prone to cracking and bursting; they comply with EN 1046, ISO 13479, and DIN 8077 standards.

  • Complete specifications and categories to meet water supply requirements in multiple scenarios

    It has a full range of pressure levels of S5-S2.5, equipped with common categories such as elbows, tees, valves, etc., with complete specifications, suitable for hot and cold high-pressure water supply in home decoration, hotels, hospitals, floor heating, tooling and other scenarios; it complies with GB/T 18742, ISO 15874, and DIN 8078 standards.

  • Light weight, convenient and efficient home decoration construction

    The material is lightweight, easy to cut, easy to hot-melt butt, and is flexible and convenient to install. It is suitable for small construction spaces such as concealed burials, suspended ceilings, and tube wells, effectively improving construction efficiency.

  • Insulated and flame retardant, safe and reliable to use

    It has excellent insulation performance, is non-conductive and is safe to use; it supports flame retardant modification, complies with the fire protection regulations for indoor water supply in buildings, and is suitable for various types of civil and commercial building water supply systems.

  • Ultra-long service life and low operation and maintenance costs

    It is resistant to aging, high and low temperature alternating, and has stable performance. The service life of cold water pipes is ≥50 years, and the hot water pipes are ≥25 years. It is maintenance-free and has low operation and maintenance costs; it complies with GB 50235, AWWA C906, and DIN 4124 standards.
