PPR copper fittings usually refer to PPR pipe fittings with copper inserts. In piping systems, they are mainly used for the connection and functional expansion of PPR (random copolymer polypropylene) pipes. Copper inserts can serve as a connection bridge between PPR pipes and metals (such as copper pipes, stainless steel pipes) or pipes made of other materials, solving the sealing problem caused by the difference in thermal expansion coefficients of different materials. In addition, PPR copper inserts offer internal or external thread interfaces, enabling PPR pipe fittings to be directly tightened with threaded metal fittings such as faucets and Angle valves, thus avoiding the problem of easy wear of pure plastic threads. PPR pipe fittings reinforced with copper parts are more suitable for high-pressure and high-temperature environments (such as hot water systems).<\/p>\n

\u25cf The advantages of PPR copper pipe fittings
\n<\/strong>\u27a8Material characteristics: Outer layer PPR+ embedded copper core, combining the corrosion resistance of plastic pipes with the strength of metal pipes
\n\u27a8Natural antibacterial property: Copper ions inhibit bacterial growth (antibacterial rate > 99%)
\n\u27a8Good sealing performance: Copper and PPR are combined through hot melt or injection molding, providing strong leak-proof performance.
\n\u27a8Anti-freezing crack design: No deformation in a low-temperature environment of 30\u2103
\n\u27a8Durability: Copper is resistant to rust, extending the service life of pipe fittings
\n\u27a8Flexible installation: It retains the convenience of PPR\u2019s hot-melt connection while being compatible with the mechanical connection of metal parts.<\/p>\n

\u25cf\u00a0Application scenarios:
\n<\/strong>1. Hot and cold water systems: Water supply pipes for households and commercial buildings, especially hot water pipes (copper is heat-resistant, PPR is corrosion-resistant).
\n2. HVAC system: Connection of floor heating and radiators. Copper parts can withstand long-term thermal expansion and contraction.
\n3. Industrial pipelines: In situations where mixed material connections are required, such as in chemical and food processing equipment (PPR is corrosion-resistant, while copper parts provide strength).<\/p>\n

\u25cf Comparison table of technical parameters of different Pipe fittings
\n<\/strong>| Indicators | PPR Copper Fittings | Common PPR Fittings | Metal Fittings |
\n| Working pressure | PN2.5MPa | PN2.0MPa | PN3.2MPa |
\n| Antibacterial performance | 99% antibacterial | None | Effective in some copper tubes |
\n| Coefficient of thermal expansion | 0.12mm\/m\u00b7K | 0.15mm\/m\u00b7K | 0.02mm\/m\u00b7K |
\n| Connection method | Hot melt + copper locking | Pure hot melt | Threaded\/Welded |<\/p>\n

\u25cf Installation precautions for PPR copper pipe fittings
\n<\/strong>1. Special tool requirements:
\n1) Special hot melt die heads for copper tubes (with limit slots) must be used.
\n2) The welding temperature is 10\u2103 lower than that of ordinary PPR pipes (250\u2103 is recommended).<\/p>\n

2. Key Points of construction
\nAfter cutting, the cross-section of the copper layer needs to be treated with a deburring tool
\n2) After hot melting, it needs to be left to stand and cool for 30 seconds (ordinary PPR only requires 15 seconds).<\/p>\n

\u25cf\u00a0<\/strong><\/b>Precautions for the use of PPR copper fittings:
\n<\/b><\/strong>1. Avoid electrochemical corrosion: In a humid environment, direct contact between copper and certain metals (such as steel) may cause galvanic corrosion, and insulating gaskets should be used for isolation.
\n2. Choose high-quality products: Inferior copper inserts may cause the PPR to bond poorly with the copper, leading to water leakage.<\/p>\n
