Coal mine underground polyvinyl chloride (PVC) pipes are the company's own intellectual property products with national invention patents and have all obtained the National Mine Product Safety Mark Certificate (MA). The PVC pipes used underground in coal mines are a new type of pipes. The excellent impact resistance guarantees safe operation in underground coal mines, which fully embodies the advantages of “plastic-steel substitutes” for energy saving, environmental protection and green convenience.
Mine pvc methane drainage pipes’ features
The pvc gas drainage pipes for mining or coal mining are based on its excellent electric insulation performance because it is made of special polyethylene(PE) material, its antistatic elements are evenly distributed on the surface and inner layer of the pipes, and the national industrial standards of internal resistance composite. Its good thermal performance is due to its use of steel-plastic composite structure, gas pipe flame retardant performance is better than pure plastic pipes. It also has a good adsorption capacity because its inner wall coating should have a strong adhesion ability, and can reduce the deposition of deposit impurities in the tube by in-tube explosion and shot blasting.
applications
Application of PVC gas/methane drainage pipes for coal mine
How much do you know about the application of PVC gas/methane drainage pipes in coal mine? The use of gas/methane drainage pipes in underground coal mines is extremely extensive. The reasons for the widespread use of methane drainage pipes are as follows:
PVC pipes are the piping materials of choice for service in oil, oilfield water, brine water service, multiphase solutions and many other energy applications including non-federally regulated gas gathering, coal-bed methane, shale methane and landfill methane recovery applications.
01. Underground mines use PVC gas/methane drainage pipes for coal mines with reliable connection performance: The interface of PVC pipes for coal mines can be flanged or glued. If it is properly constructed, joints will not be disconnected due to the action of external forces.
02. Mine underground PVC gas/methane drainage pipes have more reliable safety performance: high crack resistance, pc, s4≥0.9Mpa. Excellent drainage performance of the gas drainage pipe - Yifeng brand coal mine PVC pipe with smooth inner wall, absolute roughness k = 0.01mm, and k value does not change with time.
03. Excellent anti-wear performance of mining PVC gas/methane drainage pipes for underground coal mines: Tests show that the anti-wear performance of PVC pipes is 4 times that of steel pipes. The wide temperature range of the gas drainage pipe , -20～+40°C is the safe use scope of PVC pipes
04. Excellent corrosion resistance of gas/methane drainage pipes for underground coal mines: Except for a few strong oxidants, it can resist the erosion of various chemical media.

advantages
Why do coal mines need gas/methane drainage?
What are the advantages of mining PVC gas/methane drainage pipe?
02. The outstanding corrosion resistance of the PVC gas/methane drainage pipe for mining is resistant to corrosion of various chemical media, except for a few strong oxidants. Flame-retardant anti-static functions are in line with national standards.
03. The superior construction features light pipe, simple welding process, convenient construction, and low construction cost. The superior sealing function is a good sealing material in itself, so it is not necessary to add a seal.
04. There are many aspects of metal pipe can not be replaced, in the functional advantages of the PVC gas/methane drainage pipe for mining
