PE tube is currently applied in various fields, and can be said to be everywhere.
Then what should we pay attention to in the installation of PE pipe?
1. PE pipe has low hardness and poor rigidity compared with metal pipe. It should be protected in handling and construction to avoid mechanical damage caused by inappropriate external force. In the dark compress to mark the location of the pipeline, so as not to damage the pipeline second decoration.
2, in addition to the metal pipe or water device connection with threaded inserts or flanges and other mechanical connection, the rest should be hot melt connection, so that the pipeline integration, no leakage point.
3, PE pipe below 5℃ there is low temperature brittleness, winter construction should be careful, the pipe should be cut slowly with a sharp tool. The installed pipes should not be pressed or knocked, and the parts vulnerable to external forces should be covered with protective objects.
4, its linear expansion coefficient is large, in the open or not directly buried dark compress pipe must be taken to prevent the pipe expansion deformation of technical measures.
5. Pressure tests shall be conducted before sealing pipe and covering decorative layer after pipe installation. The test pressure of the cold water pipe shall be 1.5 times of the working pressure of the system, but shall not be less than 1MPa; the test pressure of the hot water pipe shall be 2 times the working pressure, but not less than 1.5MPa.
PE steel wire mesh skeleton pipe construction advantages
The rigidity, strength and impact resistance of PE steel wire mesh skeleton pipe are similar to the linear expansion coefficient and creep resistance of other steel pipes. Different from ordinary plastic pipes, the anticorrosion performance is different. Because of its superior anticorrosion performance, low thermal conductivity, excellent cost performance, health and non-toxic, the inner wall is smooth, no scaling, and the pipe head loss is 30% lower than that of the steel pipe.
China HDPE parts factory says PE wire mesh skeleton pipe is the best substitute for steel pipe, ductile pipe and pure plastic pipe.
The structure of the pipe is excellent, and the reinforced skeleton of the pipe and the inner and outer layer of plastic are mutually contained into a whole, without the worry of stripping the inner and outer layer of plastic and the reinforcement. Because the plastic is composed of the structure of two materials, it does not occur the rapid stress cracking phenomenon that plastic pipe is difficult to overcome.
Light weight, easy installation, pipe connection using electric hot melt joint, strong axial tensile resistance, connection technology is mature and reliable, pipe fittings, complete specifications, can be connected with different kinds of pipes, valves, equipment.
PE wire mesh skeleton pipe overall reliability is superior, and PE wire mesh skeleton pipe manufacturers, by adjusting wire diameter, wire root number, etc., can produce different pressure levels of products.
