Description
This Pre Insulated PP-R Pipe is one of the three types of corrugated pipes, also called random copolymer corrugated pipes, which are generally used in embedded walls or embedded pipes in deep wells. The pipe fitting is made by hot welding, which has corresponding plasticity and smooth wall. It is made of high-density foaming technology, which is uniform and dense, and the foaming rate of polyurethane is as high as 95%. This high-density foaming technology can make the pipe have better thermal insulation performance and better thermal insulation effect, thus effectively protecting the water temperature in the hot water pipeline, and the long-term temperature resistance can reach 80 degrees Celsius. In addition, the pipe is tightly bonded with the outer protective pipe, thus isolating the infiltration of air and water, which can play a good role in corrosion protection.
Features
1. Good insulation performance: The insulation layer of this Pre Insulated PP-R Pipe is a fully closed-cell foam structure, which makes it difficult for water in the outside air to penetrate into the material, and has excellent water seepage resistance, and will not be deformed by conveying hot water after long-term use.
2. Long service life: its service life can reach 30 years. Proper installation and use can make the maintenance cost of the pipe network extremely low. It also has good corrosion resistance and impact resistance at low temperature.
3. Good thermal insulation performance: through the design of three-layer thermal insulation layer and the selection of materials, it has good thermal insulation performance, which can ensure that the temperature of the conveying medium is not affected during transportation.
4. Convenient construction: The pipe can be made by prefabricating thermal insulation pipes or wrapping thermal insulation materials on site, which is convenient for engineering construction and will not be affected by the environment, and can ensure the accuracy of construction period and construction quality.
How to install
1. Connection of work pipes: Direct hot melt welding of both ends of PPR pipes.
2. Insulation layer: Using polyurethane tile shell, two pieces butt joint
3. Casing pipe: You can use heat shrink sleeves or electric melt sleeves to heat shrink and bond tightly.
