Pressure test of PE steel mesh skeleton

23-02-27

When the equipment system for the pressure test of the PE steel wire mesh skeleton is stable, increase the pressure to 1.5 times the working pressure, stabilize the pressure for 1 hour, carefully observe the pressure gauge, and patrol along the line, if there is no visible leakage during the test or A significant pressure drop occurs. When welding the replaced electric fusion pipe fittings, be sur

Conventional temperature of PE pipe in building wa

23-02-22

The field of building water supply, especially home decoration, requires the use of hot water pipes. The heat-resistant temperature of conventional PE pipes is 60°C, and the conventional temperature of household water supply will be around 50°C. It will run at this temperature for a long time. The PE pipe should be laid below the freezing line. In residential quarters, industrial parks and industr

The aging speed of PE pipes will be greatly accelerated in high-temperature environments, not to mention that the dominant temperature will be far above 50°C, so PE pipes are not suitable for hot water transportation. Good heat dissipation means that the thermal insulation effect is also better, but it is used in Hot water piping. The temperature of the PE pipe is generally controlled between 80-1

What are the advantages of HDPE water supply pipes in pe drainage pipes? HDPE water supply pipes are widely used, mainly because they have advantages that other pipes cannot match: 1. It is easy to form a closed anti-seepage system by butt welding and electrofusion welding. When the hdpe water supply pipe is laid along the trench, it can reduce the excavation of the trench and reduce the amount

Trenchless pipe jacking construction: refers to the use of geotechnical drilling technology to lay, repair, and replace underground pipes without excavating the surface. Pipe jacking technology is not only a specific trenchless pipe laying method, but also a general term for some trenchless pipe laying technologies based on pipe jacking construction principles. It is called trenchless pipe jacking

The application of plastic pipes at home and abroad starts from a smaller diameter and gradually develops to a larger diameter. (There is no definition for the large diameter. The large diameter mentioned in this article refers to the diameter above 800mm.) It is worth noting that in recent years, there has been a general trend of developing large-diameter plastic pipes in the world. The root of t
