Shandong PE pipe manufacturersTell me about the characteristics of PE pipe
PE pipe is a common kind of pipeline. The pipeline covers every corner of the city. In order to make people's life more comfortable, the company has been improving the processing technology and use experience of PE water supply pipe from many aspects.
PE pipe, is the use of PE (high pressure polyethylene) raw materials made out of the water supply pipe, because of its strength, corrosion resistance, non-toxic and other advantages, widely used in water supply pipe manufacturing industry. At the same time, because the PE water supply pipe is not easy to rust, it is a pipe fitting that replaces the general iron water supply pipe.
Shandong PE pipe manufacturersStorage and service life of PE pipe
PE pipe has an application date. Generally, it cannot be stored for more than 2 years. In order to ensure the use experience of new products, it must be checked before use, so as not to cause normal start-up in the later period.
After the PE pipe is filled with water, the air in the pipe is first discharged. The pressure change duration shall not be less than 10min, and the pressure should be filled with a manual pump. 1h after the surge tube exceeds the required test pressure, the test gas pressure shall not exceed 0.06MPa. It uses a PE pipe to charge compressed gas, the pipe is additionally equipped with a refrigeration shaping sleeve, so that the surface of the pipe fitting is pasted in the shaping sleeve to quickly refrigerate and harden the bottom and set the external specifications. The pipe fitting is evenly drawn out by the traction device.
When connecting PE pipe piles, the left and right section piles shall be kept flat, and the displacement error is not suitable to exceed 2mm. When carrying out prefabricated pile patchwork for PE pipe, corresponding anti-corrosion measures shall be taken for the connector of prefabricated pile according to the above regulations according to the engineering geological conditions. If the surface of the pipe is favorable, remove and smooth the wavy lines below 50mm around the damaged position, and save them in the same way as above. When the damage exceeds 1/12 of the pipe diameter, the damaged pipe or the whole pipe shall be replaced and paved again.
The daily storage and service life of PE pipes will also store them in multiple areas such as warehouses, and then take them out during use. The relative height of the pipe fittings is not suitable for more than 1.5 meters. If it is too high, the safety factor is not too high. Because the inner cavity of PE pipe is smooth, the friction resistance of liquid transportation is significantly lower than that of cast iron drainage pipe. The unsmooth rate of the inner cavity of the pipe is 0.001, while the cast iron drain pipe is 0.013, so under the same scope of application, the water delivery capacity of the previous one is 30% higher than that of the cast iron drain pipe.
The storage and service life of PE pipes in winter should be backfilled to the top of the pipe for more than double the pipe diameter. When the soil is not returned at the end of the pipeline construction, in case of small blisters, the pipe separation line and pipe bottom elevation shall be re-measured and visual inspection shall be carried out.
