China Manufactory Aluminum Hot Water Fitting Durable Insulation PPR Pipe Fittings For NET/OA/AMS 30 Days
1. ppr elbow is a pipe fitting that changes the direction of the pipeline
2. ppr union and pipe sleeve are used for the connection between ppr pipe and metal pipe
3. The ppr tee and spool are used to change the direction of the fluid
4. The ppr cap and plug are used to seal the reserved tube
5. The holding card, high card and low card of Ppr pipe fittings are used to fix the pipe
6. Ball valve: The main feature is its compact structure, easy operation and maintenance.
7. The opening and closing parts of the globe valve are plug-shaped discs, the sealing surface is flat or conical, and the discs move linearly along the center line of the fluid.
8. Y-type filter is an indispensable filter device for the pipeline system of conveying medium.
9. The valve magnetic lock relies on the force of the magnetic force to control the opening and closing of the closing member in the valve.
10. The quick-open ball valve is evolved from the plug valve. Its opening and closing part is a sphere, and the sphere is rotated 90° around the axis of the valve stem to achieve the purpose of opening and closing.

Good corrosion resistance: Except for a few oxidants, it is resistant to erosion by various chemical media, will not rust, will not corrode, will not breed bacteria, and has no electrochemical corrosion.
Good heat resistance: when the working water temperature is 70 ℃, it can be used for a long time, the short-term use water temperature reaches 95 ℃, the softening temperature is 140 ℃, and the weight is light. The density is 0.89~0.9g/cm3, which is only one-ninth of the steel pipe and one-tenth of the copper pipe. Due to the light weight, the transportation cost and the construction strength of the installation can be greatly reduced.
Hygienic and non-toxic: PP-R material is completely composed of carbon and hydrogen, without adding any toxic heavy metal salt stabilizer, and the hygienic performance of the material has been tested by the national authoritative department.
Long service life PPR pipes have a service life of more than 50 years under the rated operating temperature and pressure.
Small water flow resistance: The inner wall of the pipe is smooth and will not scale. The friction coefficient is only 0.007, which is much lower than that of metal pipes. The water passing capacity is more than 30% higher than that of metal pipes of the same specification.
Good thermal insulation performance: Due to the low thermal conductivity of PP-R material, the thermal conductivity at 20 ℃ is 0.21 ~ 0.24W/mk, which is much smaller than that of steel pipe, so PP-R pipe has good thermal insulation performance.
Small expansion force: Due to the small elastic modulus of PP-R material, the expansion force caused by temperature changes is small, and it is suitable for direct burial and concealed laying in embedded walls and floor surfaces.
System connection is firm: PP-R pipes are connected by hot melt connection, connecting pipes and fittings of the same material into a whole, and the tensile, bending and impact strength of the interface are higher than the strength of the pipe body, thus preventing water leakage hazard.
1. PP-R pipe has lower hardness and poorer rigidity than metal pipe. It should be protected during handling and construction to avoid mechanical damage caused by improper external force. The location of the pipeline should be marked after the dark application, so as to avoid damage to the pipeline due to the second decoration.
2. PP-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 press or knock the installed pipeline, and cover the parts susceptible to external force with protective materials if necessary.
3. PP-R pipes are prone to aging and degradation after long-term exposure to ultraviolet rays, and must be wrapped with a dark protective layer when installed outdoors or in direct sunlight.
4. PP-R pipes should be connected by hot-melt connection except that they are connected with metal pipes or water appliances using mechanical connection methods such as threaded inserts or flanges, so that the pipes are integrated and there is no leakage point.
The coefficient of linear expansion of the
5. PP-R pipe is relatively large (0.15mm/m°C), and technical measures to prevent the expansion and deformation of the pipe must be taken when laying the pipe in the open or non-direct burial.
6. After the pipeline is installed, the pressure must be tested before sealing (direct burial) and covering the decorative layer (non-direct burial). The test pressure of the cold water pipe is 1.5 times the working pressure of the system, but not less than 1MPa; the test pressure of the hot water pipe is 2 times the working pressure, but not less than 1.5MPa. The pressure test time and method are specified in the technical regulations. regulations.
