PPR outer wire reducing coupling is a type of pipe fitting used to connect PPR pipes of different diameters. It can achieve a smooth transition of pipes of different diameters in the pipeline system, ensuring smooth water flow and reducing energy loss. One end of the variable diameter PPR pipe fittings is connected to PPR water pipe or other pipes using hot melt, and the other end is connected to pipelines or valves using stainless steel structure threads. At the same time, PPR pipes are widely used in household and industrial water systems due to their high temperature resistance, corrosion resistance, and durability.

Installation steps

1. Preparation stage: Before installation, first ensure the cleanliness of PPR pipe and fittings, remove burrs and dust from the pipe mouth.
2. Welding process: Place the connection parts of PPR pipe and fittings into the heating sleeves of the welding machine, heat them to the appropriate temperature, and quickly and evenly insert them into the required depth without rotation, forming a uniform flange.
3. Cooling solidification: After welding is completed, maintain sufficient cooling time to ensure the solidification of the connection area and achieve the desired connection effect.

Matters needing attention

1. The welding temperature and time should be strictly controlled, as being too high or too low can affect the welding quality.
2. During installation, avoid rotating to avoid damaging the welded joint.
3. After welding, a pressure test is required to ensure that there is no water leakage at the connection.

Application scope
PPR outer wire diameter reduction is widely used in fields such as construction, water supply and drainage, HVAC, industrial pipelines, etc. Its diverse specifications and models can adapt to the special needs of various pipeline systems, providing more choices and flexibility for the design and construction of pipeline systems.
