PVC wire skeleton pipes use a new type of PVC reinforced material, which has a very good improvement in compressive strength and hardness. In the PVC wire skeleton pipes, there are multiple production methods in the market, includes high-pressure steel wire skeleton pipes, low-pressure steel wire skeleton pipes, steel wire frame pipes, and transparent steel wire skeleton pipes, which are used in different environments. The PVC steel wire skeleton pipe are the most widely used product for today markets.
PVC steel wire hoses can be classified into industrial grades (specialized for industrial water, oil, sewage, powder, chemical raw materials, etc.) and food grades according to their use (food plants conveying juice, milk, drinking water, wineries conveying liquor, beer, etc.), No matter what kinds of use, the material itself must be "non-corrosive" and "low-concentration chemical". The PVC steel skeleton hose produced by our company is mainly used for coal mine gas drainage or coal mine ventilation.
PVC steel wire skeleton pipe is a PVC hose with a built-in steel skeleton. Inside and outside the tube wall is transparent, smooth, no bubbles, fluid transmission is clearly visible; resistant to low concentrations of acid and alkali, high elasticity, not easy aging, long service life; anti-high pressure, can maintain the original state under high pressure and vacuum.
Coal Mine gas drainage PVC steel fiber composite high pressure hose is our company's patented products, has obtained the national utility model patent. This product uses high-strength fiber and high-quality galvanized spring steel wire as reinforcement material, which combines the characteristics of PVC steel spiral-enhanced hose and PVC fiber-reinforced hose, and combines the advantages of the two to make it bear positive pressure-resistant and negative pressure at the same time. Which is a composite high pressure pipe. The original shape can be maintained during the discharge process, which greatly enhances the compressive performance of the product. The pressure resistance can reach 2-4 times than the steel wire spiral reinforced hose and 1-2 times than the fiber reinforced hose. At the same time, color marking lines can be added on the pipes surface to make the products more beautiful, which greatly expands the use of PVC hose products.
Mine use steel wire skeleton hose is used to extract out the gas/methane that is rich in coal seams. It is the most effective measure to remove the threat of gas accidents and ensure the safety of coal mines. Gas drainage is the fundamental measure and the main approach for the management of coal mine gas, which can make gas change into a treasure (power generation, supply gas company, automobile fuel, etc.), which is of great significance for coal mine safety, environmental protection, and resource utilization. The sealing hole pipes is the terminal technology of the extraction gas projects. The sealing hole pipes' quality directly affects the extraction concentration and extraction efficiency.
Coal Mine gas/methane drainage PVC hose connection hose adopts double-sided anti-corrosion material, has good impact strength and flexibility, and can withstand the impact of external forces without leakage. The gas connection hose has good fluid performance, no scale formation, high gas drainage rate, and environmental protection.
1. Easy installation and construction, reduce labor intensity, increase working efficiency; corrosion resistance, greatly reduce loss for the pipeline.
2. wall is smooth, low fluid resistance; flame retardant anti-static, cutting or collision does not produce sparks
3. can be used in coal mines, chemical industry, gas, mines and other flammable, explosive and other specific places
4. corrosion resistance, chemical stability, no need for anti-corrosion treatment, greatly increasing the life of the gas pipelines.
5. When in the process of installation and transportation, handle gently, avoid throwing and dragging. Strong impact is strictly prohibited.
6. When the temperature have large difference between the storage location of the pipe fittings and the construction site, before the connection, pipes and fittings should be placed on the construction site for a certain time to bring the temperature close to the construction site temperature.
7. When the pipes are transported into a wall, it should be prevented from scratching, twisting, or excessive stretching and bending.
