Key Selling Points
·Specifically addresses corrosion issues in closed-loop heating systems' metal fittings, meeting the long-term needs of overseas heating markets and reducing customer complaints.
·The green outer layer offers superior weather resistance compared to ordinary natural-colored PPR, suitable for ceilings, pipe wells, and underground installations (sheathing is recommended). For long-term outdoor installations, a sunshade/insulation sleeve is recommended.
·Pipes, all-plastic fittings, brass insert fittings, and valves are all self-produced, eliminating the need for customers to purchase from multiple sources and saving on procurement and logistics costs.
·The inner layer uses food-grade raw materials, suitable for both heating and domestic hot water, meeting drinking water safety standards in multiple countries.
Product Details
·Appearance Details: The outer wall of the pipe has a uniform matte dark green finish, free of scratches, shrinkage pits, and discoloration; the inner wall is pure white and smooth, free of black spots and impurities; the cross-section features three clearly defined layers: a green outer layer + an oxygen barrier layer + a white inner layer, with no delamination or peeling.
·Printing Details: The pipe body can be printed with brand logos, product models, pressure ratings, outer diameters, wall thicknesses, and applicable standards; the lettering is clear, abrasion-resistant, and will not fade even after long-term underground installation.
·Manufacturing Details: A three-layer co-extrusion process (PPR outer + EVOH oxygen barrier + food-grade PPR inner) is used, eliminating the need for post-installation bonding. Layer separation will not occur after bending or heat fusion. Matching pipe fittings are integrally injection molded with uniform wall thickness and no thin areas.

FAQ
Q: Which pressure specification should I choose for home underfloor heating?
A: Ordinary wall-hung boiler underfloor heating → S4 PN1.6; High-rise/Northern centralized heating → Recommended S2.5 PN2.5; Commercial shops → S2.5 PN2.5.
Q: Can it be used for domestic hot water simultaneously?
A: Inner layer is made of food-grade PPR material, suitable for both heating and domestic hot water use, with no harmful substances leaching out.
Q: What is the hot-melt application temperature? Do I need to peel off the outer green layer?
A: The hot-melt standard is 260℃. Grinding or peeling the outer layer and oxygen barrier layer is strictly prohibited. Only a complete weld can preserve the oxygen barrier properties.
Q: Can the entire heating system be supplied in one stop?
A: We can supply a complete set including PE-RT underfloor heating pipes, copper manifolds, and PPR copper valves from the same manufacturer, ensuring higher system compatibility.
