Shandong PE pipe manufacturers to identify the good or bad method of PE pipe
Shandong PE pipe manufacturers to identify the good or bad method of PE pipe PE pipe specifications are all refers to the diameter, matching the difference in pressure level, the thickness of the water supply pipe may be different. Users can choose their own interface mode according to the pipe diameter, pressure, application site and other places. In the underground environment of PE pipe, due to the influence of underground movement and end load, the water supply pipe buried in the soil must have good flexibility.
Shandong PE pipe manufacturersIntroduce the method of distinguishing the good and bad of PE pipe
how to learn some methods to distinguish the good and bad of pe tube. how good pe pipe, how bad pe pipe. Let's talk about a good PE pipe, using PE water supply pipe. The surface of PE tube is smooth and bright, with some chromaticity. The second pipeline is darker, and the darker it is, the larger the pure raw material used in the pipeline.
PE pipe is not easy to rust, can replace the general iron water supply pipe fittings. Due to the limitations of other pipe fittings, many PE pipes are now used to replace the previous pipes. Because of the friction resistance of PE pipe and the superior performance of the insulation layer, coupled with its own resistance to gas pressure and good pull and push, now in many power engineering assembly line construction process, often used.
PE pipe specifications are all refers to the diameter, matching the difference in pressure level, the thickness of the water supply pipe may be different. Users can choose their own interface mode according to the pipe diameter, pressure, application site and other places. In the underground environment of PE pipe, due to the influence of underground movement and end load, it is necessary for the water supply pipe buried in the soil to have good flexibility.
The same is true for distinguishing the quality of pe gas pipes. According to similar pe gas specifications, natural gas is generally introduced with a small diameter of dn500 or more, and then natural gas is pulled to different places through various pipelines. Because PE pipe is a new type of water supply pipe, pipe material is relatively light and strong corrosion resistance and other advantages, its engineering construction and general water supply pipe has a very big difference. The hand feels that there is a kind of grinding yarn, the ductility of the pipeline is also weak, and the pressure is not enough.
Shandong PE pipe manufacturers: PE pipe can prevent pipe fittings from resilience
PE pipe can prevent the pipe fittings from resilience, so that the pipe fittings are tightly attached to the heating plate, thus improving the actual heating effect and reducing the heating duration. The time of the heating period is related to the cross-sectional area of the welded pipe, the ambient temperature of the heating plate and the working temperature. PE pipe is a kind of high toughness material, which has strong adaptability to subgrade foundation settlement. This characteristic makes it a telescopic pipeline that can resist earthquake disaster, concrete crack and temperature difference. There is no certain on-line control method for pipe production, so it is impossible to guarantee the thickness and symmetry.
PE water supply pipe has a good pressure, so that the original lining of the pipeline after repair to withstand the pressure has been greatly improved. The experimental results show that the seamless steel pipe lined with 8mm thick HDPE pipe can withstand the working pressure of 7Pa, while the seamless steel pipe without HDPE pipe can only withstand the working pressure of 5Pa. Here, it is also necessary for the manufacturer to do a lot of experimental pipe fitting resilience and choose the appropriate pipe fitting blocks to produce and manufacture. According to the harm of compressed gas to the quality of pipe fittings, pe pipe manufacturers make the pipeline shape and maintain a certain concentricity.
