What should be paid attention to when welding PE pipes in summer

1. Check whether the parts of the welding machine are working normally, especially pay attention to whether the temperature of the heating plate of the welding machine is within the standard temperature range (220℃±10℃) before use. 2. The adjustment of the temperature of the heating plate should consider the influence of the surface temperature and the ambient temperature on the actual temperature of the heating plate, to prevent the actual temperature of the heating plate (surface temperature + ambient temperature + heating plate display temperature) > 230 ℃. When the ambient temperature is above 38°C and construction is carried out on the asphalt road, the temperature of the heating plate can be adjusted to between 190°C and 200°C; when the ambient temperature is below 38°C and the construction is carried out in the field, the temperature of the heating plate can be adjusted to 200°C -210℃. 3. Check the misalignment rate before the pipes are connected, and the misalignment rate is not more than 10% of the wall thickness of the pipe. If the misalignment rate exceeds 10% of the wall thickness of the pipe, the contact surface of the weld will be smaller than the wall thickness of the pipe, which will affect the welding effect.

The difference between PE water supply pipe and PE drainage pipe

Jun 30,2022

1. Pressure PE water supply pipes are used to transport tap water, and generally need to pump water from the ground to the ground and residents' homes. Since the PE water supply pipe needs to bear the pumping pressure, the water supply pipe is generally divided into five levels according to the pressure, namely 0.6 MPa, 0.8 MPa, 1.0 MPa, 1.25 MPa, and they bear 6 kg pressure, 8 kg pressure, 10 kg pressure , 12.5kg pressure and 16KG pressure. The higher the pumping pressure, the higher the pressure level requirements for the PE water supply pipe. Polyethylene drainage pipes are generally used to discharge sewage and flow from top to bottom, so polyethylene drainage pipes generally do not need to consider the pressure level.

Matters needing attention in PE drainage pipe construction

Jun 30,2022

1. Before installing the pipe: Carefully check whether there is any damage in the process of loading, unloading, transportation and stacking. If any defective pipes such as damaged cracks and deformation are found, they should be removed in time. 2. Inspection well and pipeline connection: The flexible joint sealed with flexible packing should be adopted, and the specific structure shall be carried out according to the design requirements. 3. When excavating trenches and making foundations, attention should be paid to: (1) The net width of the groove bottom should be used according to the outer diameter of the pipe plus 0.6m; (2) Drainage measures should be taken during trench excavation to prevent the bottom of the trench from being soaked in water;

Before using the PE pipe, it should be fully prepared

Oct 15,2018

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!

How to conduct water tightness test for PE pipe fittings

Oct 15,2018

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.

PE pipe: high availability

Jun 30,2022

PE pipe is beautiful and hygienic, easy to install, safe and reliable, and the price is favorable. It is suitable for laying in urban water supply pipes, green irrigation pipes, and some places that need to withstand high pressure, and has become a mainstream product in the water supply industry. The common nominal diameters are printed on the PE pipes, and the letters represent 'dn', such as dn110, dn315, indicating that the nominal diameters of the pipes are 110mm and 315mm; some pipes will also be printed with de90, de160, which means that the pipe outer diameter. PE pipe: beautiful and hygienic, easy to install, safe and reliable The flexibility of the PE pipe makes it easy to bend, and the engineering can bypass obstacles by changing the direction of the pipe. In many occasions, the flexibility of the pipe can reduce the amount of pipe fittings and installation costs.

PE pipes do not need anti-corrosion treatment and maintenance

Jun 30,2022

E pipe does not need anti-corrosion treatment, maintenance-free, and has a lifespan equivalent to that of a building. It solves the problems of traditional pipe products, such as corrosion, aging, water leakage, and unsanitary in a short time. PE pipe effectively eliminates product maintenance and renewal costs. PE pipes do not need anti-corrosion treatment and maintenance The PE pipe manufacturer points out that the expansion volume needs to be larger than the storage volume required for the instantaneous flow of the transverse branch pipe. The discharge status of the outlet pipe is mainly to avoid burying, which leads to the decrease of the flow of the entire drainage system; this echoes the rational planning of the drainage project of the whole project. PE pipelines have a variety of construction techniques. In addition to traditional excavation methods, various new trenchless techniques such as pipe jacking, directional drilling, lining pipes, and cracking pipes can be used for construction. PE has excellent resistance to most household and industrial chemicals. Certain types of chemicals are chemically aggressive, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene), and halogenated hydrocarbons (carbon tetrachloride).

What should I do if the wall thickness of the pe pipe manufacturer is uneven?

Jun 30,2022

1. Check whether the temperature of the downstairs mouth is stable, the hand feeling is not hot, and whether the water in and out is enough (for a pipe that is uneven before and after) 2. Adjust the wall thickness on the mold, and adjust the size of the gap around the mold. The small diameter is always around, and the large diameter is always up and down. 3. Adjust the angle of the vacuum forming machine and the nozzle in the spray box to make the pipe cool evenly 4. Adjust the water outlet of the sizing sleeve (ditch tip water hole) to make the water outlet evenly 5. The caliber can adjust the wall thickness drawing ratio to reduce the influence of the melting hammer on the tube wall thickness 6. The pe pipe manufacturer disassembles the mold, checks whether the screws inside the mold are loose, and re-tighten them
