Installation instructions for PPR pipe and fitting

When handling PPR pipe and fittings, throwing, falling, rolling and dragging are strictly prohibited in order to avoid damage to the ppr pipe and fittings.

Before joining PPR pipe and fittings, two ports should be checked. If there is damage, they must be cut off. Hot melt connection should be adopted. If there are bad phenomena such as decomposition, discoloration, burning and smoking at the interface, the welder must be replaced. When connecting threaded pipe fittings with other fittings, attention should not be paid to tightening too tightly to avoid damage to threaded pipe fittings. When connecting with water heater, it is advisable to adopt metal pipe or hose transition connection, the length should not be less than 300 mm, while outdoor open-packed pipes should adopt measures of heat preservation, sun protection and freeze protection. When the temperature is close to 5 degrees Celsius in winter, the pipes and fittings should be strictly prevented from accidental damage during handling and construction, and the water should be released in time after test pressure is completed; if there is no reliable heat preservation measures in winter, water should be used for a long time. The water in the pipeline is emptied to prevent expansion of the pipeline.

After the installation of the pipeline, hydraulic test must be done to determine whether the pipeline can be closed or landfill without leakage. If waterproofing works are being done, do not coat paint, asphalt and other odorous materials on the surface of the pipeline, in order to avoid the odor of water quality.

Shijiazhuang Xingyin Import & Export Trading Co., Ltd. is one of the largest suppliers and manufacturers of PPR pipes and fittings in China.
