Product Introduction
The PPR all-plastic reducing elbow is a core pipe fitting specially designed for building water supply and drainage systems. It is integrally injection-molded using random copolymer polypropylene (PPR) material to achieve smooth transition and redirection between pipes of different diameters. This type of pipe fitting realizes the sealing of the pipeline system through hot-melt connection, avoiding the risk of corrosion of metal components. It is suitable for multi-specification reducing requirements from DN20 to DN160, such as combinations like 25×20 and 63×50.
Product Definition
Essential Attribute:
It is a thermoplastic pipe fitting made of 100% imported Borealis PPR resin. It has passed international standard certification and implements the latest building drainage standards to ensure pressure resistance, temperature resistance, and hygienic performance. Its core function is to realize ±90° redirection and diameter conversion from DN16 to DN160 while maintaining the continuity of the pipeline, avoiding the electrochemical corrosion problem of traditional metal pipe fittings.
Structural Characteristics:
Homogeneous Fusion: After hot-melting with PPR pipes, a molecular-level bond is formed, and the sealing life is consistent with that of the pipes (≥50 years).
Streamlined Inner Wall: The roughness is ≤0.01mm, and the water flow resistance is 30% lower than that of metal pipe fittings.
Product Applications
Core Application Scenarios
1.Connection of cold and hot water pipes in kitchens/bathrooms (brands such as Lisui and Weixing account for 65% of the market share).
2.90° corners in floor heating coil systems (need to match PN20 high-pressure grade).
3.Reducing nodes for zoned water supply in high-rise buildings.
4.Clean water pipelines in food processing enterprises.
Product Advantages
(I) Material Performance Advantages
All-Plastic Corrosion Resistance
1.No metal components to avoid electrochemical corrosion, with a service life of more than 30 years in an acid-base environment with pH 2-12.
2.A nano-scale hydrophobic layer is formed on the surface, and the scaling rate is 80% lower than that of metal pipe fittings.
Mechanical Performance Breakthrough
1.The modified PPR material has an impact strength of 28kJ/m² at -20°C, which is 120% higher than traditional PPR.
2.Long-term pressure resistance tests show that PN16 grade pipe fittings have no 破裂 time for more than 10,000 hours under the condition of 80°C/1.2MPa.
(II) Installation Economy
Hot-Melt Construction Efficiency
1.Hot-melting at 260±10°C only takes 5-10 seconds, and the daily installation volume per person can reach 3 times that of traditional threaded connection.
2.No sealant or raw material tape is needed, and the comprehensive installation cost is reduced by 25%.
Maintenance Cost Advantage
1.There is no risk of leakage within the 50-year warranty period, and the after-sales repair rate is less than 0.3%.
2.It has strong repairability, and the local replacement cost is only 1/5 of that of metal pipe fittings.
With material innovation and installation convenience, this type of pipe fitting has become the mainstream choice to replace metal pipe fittings, especially showing significant advantages in green buildings and intelligent water conservancy fields.
