PPR Water Pipe Copper Union 20 Outer Wire Union 1 Inch 32 Hot Melt Pipe Fittings For Water Supply And Drainage
----------------------------------------
Basic Info.
1. Compared with metal pipes, PP-R pipes have lower hardness and lower rigidity. They should be protected during transportation and construction to avoid mechanical damage caused by inappropriate external forces. Mark the location of the pipeline after the dark application, so as not to damage the pipeline during the second decoration.
2. There is a certain low temperature brittleness of PP-R pipe 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 if necessary, cover the parts that are vulnerable to external forces with protective materials.
3. The PP-R tube is prone to aging and degradation when exposed to ultraviolet rays for a long time. It must be covered with a dark protective layer when installed outdoors or in direct sunlight.
4. The PP-R pipe should be connected by hot melt, except that it is connected with metal pipes or water heaters using threaded inserts or flanges, and the rest should be connected by hot melt, so that the pipeline is integrated and there is no leakage point.
5. The linear expansion coefficient of the PP-R pipe is relatively large (0.15mm/m℃), and technical measures must be taken to prevent the expansion and deformation of the pipe when the pipe is exposed or not directly buried.
6. After the pipeline is installed, the pressure must be tested before sealing the pipe (direct burying) and covering the decorative layer (non-direct burying and concealing). The test pressure of the cold water pipe is 1.5 times the working pressure of the system, but not less than 1 MPa; the test pressure of the hot water pipe is 2 times the working pressure, but not less than 1.5 MPa. Pressure test time and method technical regulations stipulate.
7. When the PP-R tube is exposed or not directly buried, the support and hanger must be installed according to the regulations.
8. Cool down to the specified time and complete the connection.

Advantage
1. Non-toxic and hygienic. The raw material molecules of PP-R are only carbon and hydrogen elements, and there are no harmful and toxic elements. It is hygienic and reliable. It is not only used in cold and hot water pipelines, but also in pure drinking water systems.
2. Heat preservation and energy saving. The thermal conductivity of PP-R pipe is 0.21w/mk, which is only 1/200 of that of steel pipe.
3. Better heat resistance. The Vicat softening point of PP-R pipe is 131.5℃. The maximum working temperature can reach 95℃, which can meet the requirements of the hot water system in the building water supply and drainage code.
4. Long service life. PP-R pipe has a service life of more than 50 years under the conditions of working temperature of 70℃ and working pressure (PN) of 1.0MPa (provided that the pipe must be S3.2 and S2.5 series or above); under normal temperature (20℃) The service life can reach more than 100 years.
5. Easy installation and reliable connection. PP-R has good welding performance. The pipes and fittings can be connected by hot melt and electrofusion. The installation is convenient and the joints are reliable. The strength of the joint is greater than the strength of the pipe itself.
6. The materials can be recycled. The PP-R waste is cleaned, broken, and recycled for use in the production of pipes and fittings. The amount of recycled materials does not exceed 10% of the total amount and does not affect product quality.
