The scope of application of PE mining pipe?
My air pipes; mine water pipes; mine shotcrete pipes; mine gas pipes.
PE biogas pipes are mainly used in agriculture, landfills, and biogas resource recovery industries. At present, the main biogas pipes produced by our company have a diameter of Φ25mm-Φ400mm (more than 400mm).
Our company supplies about 100,000 meters of PE landfill pipes all year round. Our company has 4 sets of PE landfill pipe production equipment, the independent workshop area is 1500 square meters, and the production diameter is Φ63mm-Φ800mm. Anti-oxidation, strong toughness, and strong adaptability. A significant advantage of plastic pipes compared to other materials is their lower environmental impact.
PE pipe uses and applications
PE pipe as a pipe material has obvious advantages:
3. Chemical resistance
4. Overall resilience
These advantages make PE pipe an ideal pipe material for a variety of applications, such as drinking water services, water treatment projects or projects such as waste treatment and landfills, and mining tailings. PE pipes are generally resistant to most common chemicals.
■ Good hygienic performance: no heavy metal salt stabilizer is added during the processing of PE pipe, the material is non-toxic, no scaling layer, and no bacteria grow, which solves the secondary pollution of urban drinking water well.
■ Excellent corrosion resistance: Except for a few strong oxidants, it can resist the erosion of various chemical media; no electrochemical corrosion.
■ Long service life: PE pipes can be safely used for more than 50 years under rated temperature and pressure conditions.
■ Good impact resistance: PE pipe has good toughness and high impact resistance, and heavy objects directly press through the pipe, which will not cause the pipe to rupture.
■ Reliable connection performance: The strength of the PE pipe hot-melt or electro-melt interface is higher than that of the pipe body, and the joint will not be disconnected due to soil movement or live load.
■ Good construction performance: the pipeline is light in weight, the welding process is simple, the construction is convenient, and the overall project cost is low.
■ Electrothermal fusion: A special electric fusion welding machine is used to connect straight pipes to straight pipes and straight pipes to pipe fittings. Generally used for pipes below 160mm.
■ Hot-melt butt connection: use a special butt welding machine to connect pipes, generally used for pipes above 160mm.
■ Steel-plastic connection: It can be connected by flange, screw thread, and other methods.
■ To facilitate construction and ensure construction quality, corresponding tools should also be prepared.
Such as rotary cutter-cutting pipes; rotary scraper – scraping off the oxide skin on the surface of the pipe; wall scraper – scraping off the scale on the surface of large-diameter pipes; gas cut-off tool – to realize on-site operation of gas cut-off.
PE pipe connection steps:
1. Clamp and clean the port
2. Adjust and smooth the port
3. Port alignment
4. Pressure welding
5. Pressure relief cooling
■ Gold mine, tailings, mine mortar transportation pipeline
■ Landfill, etc.
■ Gas pipelines such as biogas
■ Urban water pipe network system.
■ Urban and rural drinking water pipelines.
■ Material and liquid transportation pipelines in chemical, chemical fiber, food, forestry, printing and dyeing, pharmaceutical, light industry, papermaking, metallurgy, and other industries.
■ Agricultural irrigation pipes.
■ Posts and telecommunications lines, power wire protection casing.
A good pipeline should not only have a good economy but also have a series of advantages such as a stable and reliable interface, material impact resistance, crack resistance, aging resistance, corrosion resistance, etc. Compared with traditional pipes, the PE pipeline system has the following: Series of advantages:
(1) Reliable connection: The polyethylene pipe system is connected by electrothermal fusion, and the strength of the joint is higher than that of the pipe body.
(2) Good low-temperature impact resistance: The low-temperature embrittlement temperature of polyethylene is extremely low, and it can be used safely in the temperature range of -60-60 °C. During construction in winter, due to the good impact resistance of the material, the pipe will not be brittle.
(3) Good resistance to stress cracking: PE has low notch sensitivity, high shear strength, and excellent scratch resistance, and its resistance to environmental stress cracking is also very outstanding.
⑷Good chemical corrosion resistance: PE pipes are resistant to corrosion by a variety of chemical media, and chemical substances in the soil will not cause any degradation to the pipes. Polyethylene is an electrical insulator, so it does not rot, rust or electrochemically corrode; it also does not promote algae, bacterial or fungal growth.
⑸Aging resistance, long service life: polyethylene pipes containing 2-2.5% evenly distributed carbon black can be stored or used outdoors for 50 years without being damaged by ultraviolet radiation.
⑹ Good wear resistance: The comparison test of wear resistance between PE pipe and steel pipe shows that the wear resistance of PE pipe is 4 times that of steel pipe. In the field of mud transportation, compared with steel pipes, PE pipes have better wear resistance, which means that PE pipes have a longer service life and better economy.
⑺Good flexibility: The flexibility of the PE pipeline makes it easy to bend. In engineering, obstacles can be bypassed by changing the direction of the pipeline. In many occasions, the flexibility of the pipeline can reduce the number of pipe fittings and installation costs.
⑻ Small water flow resistance: PE pipe has a smooth inner surface, and its Manning coefficient is 0.009. The smooth performance and non-adhesive properties ensure that the PE pipe has a higher conveying capacity than traditional pipes, and also reduces the pressure loss of the pipeline and the energy consumption of water conveying.
⑼ Easy to handle: PE pipes are lighter than concrete pipes, galvanized pipes, and steel pipes. They are easy to handle and install, and lower manpower and equipment requirements mean that the installation cost of the project is greatly reduced.
⑽Various new construction methods: PE pipes have a variety of construction techniques. In addition to traditional excavation methods, various new trenchless techniques such as pipe jacking, directional drilling, lining, It is the only choice for some places where excavation is not allowed, so the application field of PE pipes is more extensive.
