What is the difference between PE pipe and other plastic pipes?
1. PB tube PB pipe (polybutene) is a high molecular inert polymer, it has high temperature resistance, durability, chemical stability and plasticity, odorless, non-toxic, the temperature range is -30 ℃ to 100 ℃, Has a variety of structures and properties and a variety of uses. 2. PE pipe The raw material of PE pipe is polyethylene plastic, which is produced by a variety of process methods, is non-toxic and tasteless, does not breed bacteria, has cold resistance, heat resistance, pressure resistance, no rust, no corrosion, no scaling, and long life. , and has the characteristics of long-term aging resistance. Compared with steel pipes, the construction process is simple, and it has a certain flexibility. More importantly, it is not used for anti-corrosion treatment, which will save a lot of processes. 1. Environmental protection and hygiene: no scaling, no bacteria breeding, which solves the secondary pollution of drinking water.

Before using the PE pipe, it should be fully prepared
PE pipe fittings are widely used in the construction industry. This is because of the good advantages of PE pipe fittings. However, before using PE pipe fittings, adequate preparations should be made to avoid any problems in the later stage. Before installing PE pipe fittings, it is necessary to dig trenches, and digging trenches means that the excavated soil should have a reasonable stacking place, and the trenches should not be too close, and there should be a distance of more than two meters. The excavated soil should be transported to the outside in time, so as not to affect the future work. During the construction of PE pipe fittings, mechanical operation must be used, and the machine can be used to dig to 20 cm above the level of the bottom of the designed trench, and workers can be invited to dig the rest of the part. In order to ensure the safety of construction, construction period and construction quality, it is necessary to fully understand and investigate the soil quality and groundwater level of the construction site before construction, so as to ensure that there will be no accidents during construction!

What types of PE pipe fittings can be divided into?
PE pipes and fittings are widely used in urban and rural water supply, building drainage, ground source heat pumps and other fields. The following editor will introduce the classification knowledge of PE pipes and fittings: First of all, according to the use, it can be divided into building and municipal water supply and drainage pipes, outdoor gas pipes, agricultural irrigation pipes, threading pipes, sewage pipes, etc. Secondly, according to the quality and structure of the pipe, PE pipes can be divided into ordinary PE pipes, aluminum-plastic composite pipes, steel-plastic composite pipes, steel-plastic composite pipes, double-wall corrugated pipes, spiral pipes, silicon core pipes for optical cables, etc. Again, according to the density of raw materials, it can also be divided into high-density tubes, low-density tubes and medium-density tubes. The above is an introduction to the classification knowledge of PE pipes and fittings. Customers are welcome to come to our company for business negotiation.

How to conduct water tightness test for PE pipe fittings
PE pipe fittings can be used in water supply pipes, in addition to UPV-C pipes, steel pipes, gray cast iron pipes, glass fiber reinforced plastic sand pipes and ductile pipes, etc. The test pressure of the water tightness test of PE pipe fittings shall not exceed the pressure rating of the pipe, or 1.5 times the lowest pressure rating of the fittings in the system. When the pipeline pressure reaches the test pressure, it should be kept for a certain period of time to make the temperature of the test medium in the pipeline consistent with the ambient temperature of the pipeline. After the temperature and pressure are both stable, start timing. Under normal circumstances, the water tightness test should be stabilized for 24 hours. After the test, if there is no obvious leakage or pressure drop, the test is passed. PE pipe fittings have become the ideal pipes for water supply projects due to the advantages of low cost, convenient construction, good hydraulic conditions, non-toxicity, corrosion resistance, low temperature resistance and mechanical vibration resistance.
