50mm Hot And Cold Pipe PPR Pipe Hot Melt Pp-R Tap Water Pipe For Water Supply And Drainage
PPR is the abbreviation of type three polypropylene, also called random copolymer polypropylene pipe. It adopts heat welding method, has special welding and cutting tools, and has high plasticity. The price is also very economical. With an external insulation layer, the insulation performance is better, and the pipe wall is also very smooth, excluding the inner and outer wire joints. Generally used in embedded walls or deep well embedded pipes. PPR pipes are moderately priced, stable in performance, heat-resistant, heat-insulated, corrosion-resistant, smooth and non-scaling, the piping system is safe and reliable, impermeable, and has a service life of up to 50 years.

1. Sanitation, health and environmental protection. Polypropylene is an environmentally friendly material and can be used for drinking water transportation.
2. The joints are connected by hot melt to form a whole body without leakage. Other materials are connected with silk ports, which is less impermeable and avoids the toxicity of glue bonding.
3. The conveying resistance is small.
4. The price is cheap and moderate.
5. Long service life, it can be used for 50 years.
1PP-R pipe has lower hardness and lower rigidity than metal pipe, so it should be protected during transportation and construction to avoid mechanical damage caused by inappropriate external force. Mark the location of the pipeline after the dark application, so as not to damage the pipeline during the second decoration.
2PP-R pipe has a certain low temperature brittleness below 5℃. Be careful in winter construction. When cutting the pipe, use a sharp knife to cut slowly. Do not place heavy pressure or knock on the installed pipeline, and cover the parts vulnerable to external forces with protective materials if necessary.
3PP-R tube is prone to aging and degradation by long-term exposure to ultraviolet rays. It must be covered with a dark protective layer when installed outdoors or in direct sunlight.
4PP-R pipe is connected with metal pipe or water appliance using threaded inserts and other mechanical connection methods, and the rest should be connected by hot melt, so that the pipeline is integrated and there is no leakage point.
The 5PP-R pipe has a relatively large linear expansion coefficient (0.15mm/m℃). When the pipe is exposed or buried in a dark place, technical measures must be taken to prevent the expansion and deformation of the pipe.
6 After the pipeline is installed, pressure test must be performed before sealing the pipe (direct burying) and covering the decorative layer (non-direct burying and concealing).
The pressure test of the cold water pipe shall be 1.5 times of the working pressure of the system, but shall not be less than 0.6MPa;
The test pressure of the hot water pipe is twice the working pressure, but not less than 1.5MPa.
Pressure test time and method technical regulations
7 When the PP-R tube is open or not directly buried, the support and hanger must be installed in accordance with the regulations.
