Core Product Features and Technical Advantages
Material and Performance
Adopting high-quality PPR raw materials such as those from South Korea's Hyosung, it complies with the GB/T 18742.3-2002 standard for polypropylene fittings for cold and hot water use. It is hygienic and non-toxic, and can be directly used for drinking water transportation.
It has a wide temperature resistance range, with a long-term working temperature of up to 70℃ and a short-term tolerance of 95℃ high temperature. Its service life at room temperature exceeds 50 years.
The all-plastic structure avoids the risk of metal corrosion, is light in weight, and has excellent impact resistance, making it suitable for long-term underground or exposed installation.
Optimized Hydrodynamic Design
The large-radius streamlined Y-shaped structure can reduce water flow resistance by more than 50% and improve the uniformity of flow splitting. It is especially suitable for scenarios with high water flow requirements (such as simultaneous water use in multiple bathrooms).
Some products have built-in cylindrical nets and porous ceramic balls, which can filter impurities in water, buffer water hammer effects, and reduce the risk of pipe vibration and blockage.
Ease of Installation
It adopts hot-melt connection technology, and the pipe fitting and pipe are welded into one piece by special tools, which has strong sealing performance and no leakage risk.
The installation steps include pipe cutting, cleaning, hot melting, and butt jointing. Attention should be paid to the hot melting time and depth to ensure strength.
Application Scenarios and Selection Suggestions
Typical Applications
Home Water Supply: Split the water from the main pipeline to branch pipelines in the kitchen, bathroom, etc.
Floor Heating System: Distribute hot water to different coil circuits to balance the temperature in various areas.
Commercial Buildings: Used in central air-conditioning water circulation or multi-floor water supply and drainage systems.
Specification Matching
Common sizes include DN20, DN25, DN32, etc. The corresponding specifications should be selected according to the outer diameter of the pipe.
It is recommended to choose a pressure rating of 1.6MPa or 2.0MPa to meet the needs of home and general engineering.
Precautions and Maintenance
Anti-Freezing Measures
PPR pipes may freeze and crack below -20℃, but no special protection is required for regular use. In extreme low temperatures, thermal insulation cotton can be added or water in the pipes can be drained.
Quality Identification
Check whether the appearance is smooth, without bubbles or cracks, and the welding surface should be flat and not deformed.
Installation Specifications
Hot-melt operation must be carried out by professional personnel to avoid insufficient interface strength due to improper operation.
Expansion space should be reserved for pipe laying to avoid stress cracking caused by thermal expansion and contraction.
