PPR Water Supply Pipe System
Product Introduction
PP-R water supply pipe series products are manufactured in strict accordance with ISO9001 quality system standards. The products fully comply with GB/T18742.1-2007, GB/T18742.2-2007, GB/T18742.3, GB/T17219 sanitary standards and relevant national health safety evaluation regulations.
We have long been committed to improving product performance and customer experience, integrating European industrial technology with domestic user habits. Using unique processing technology, PP-R pipes, as a typical representative of new plastic pipe products, offer advantages such as energy efficiency, environmental protection, light weight, corrosion resistance, non-scaling, easy installation, and long service life. Compared with traditional cast iron pipes and galvanized pipes, they have higher comprehensive technical performance and economic indicators, making them the leading product for hot and cold water delivery pipelines, widely used in building, municipal, industrial, and agricultural water supply fields.
Product Features
Light WeightOnly one-ninth the weight of steel pipes and one-tenth of copper pipes. |
Secure System ConnectionPP-R pipes are connected by heat fusion welding method. |
Thermal Insulation & Energy SavingThermal conductivity of 0.24W/m·K, only one two-hundredth of metal pipes; minimal heat loss for hot water pipelines. |
Excellent Corrosion ResistanceExcept for a few oxidants, resistant to various chemical media; no rust, no corrosion, no bacteria growth, no chemical corrosion. |
Low Flow ResistanceSmooth inner wall, no scaling; water flow capacity exceeds metal pipes of the same specification by over 30%. |
Good Heat ResistanceCan be used long-term at 70°C working water temperature; short-term use up to 95°C; softening temperature of 140°C. |
Long Service LifeUnder rated service temperature and pressure, PP-R pipe service life exceeds 50 years. |
Low Expansion ForcePP-R material has low elastic modulus; expansion force generated by temperature changes is relatively small. |
Green & Eco-FriendlyNo pollution issues; classified as a green product. |
Complete SystemPP-R piping system has complete fittings to meet general engineering requirements. |
Cost-EffectivePP-R pipe prices are comparable to galvanized pipes; convenient construction with lower overall cost. |
Easy ConstructionLight weight, easy to transport and install. |
Product Advantages
| Premium Raw MaterialsPPR plastic pipe fittings use imported raw materials to avoid secondary water pollution. Brass fittings are made of HPb59-1 copper material, manufactured by stamping process with dense internal structure, ensuring sufficient strength and service life. High-grade copper material and professional fitting structure design; under hammer impact, the fitting will only deform without cracking. Advanced ProcessUnique processing technology completely solves the brittleness problem commonly found in PP-R industry; effectively addresses PPR hidden crack leakage issues; will not shatter when struck above 10°C. Unique DesignProfessional brass fitting structure design with G-type and R-type threads; excellent compatibility with no leakage; convenient installation saving time and effort with fewer turns of PTFE tape; brass fittings adopt special dovetail groove structure to prevent separation from plastic parts. |
