HDPE Mining Pipe
Introduction to HDPE Mining Pipes
Mining pipes manufactured by SinoPipe Industries are made using a unique flame-proof and anti-static type of polyethylene. They are produced through the use of high temperature-based extrusion technologies. Our company goes by the national coal industry standard MT588.1-2005 (Part 1: PE pipe), MT181-88, AQ1071-2009 for safety regulations on plastic mining pipes. We display our mines with pride by exhibiting Coal Mine Safety Signs (MA) over our polyethylene mining pipe manufacturing outlet.
Advantages Of Pipe Mining
- It is perfect for use in flammable and explosive environments due to its flame-retardant qualities and electrostatic dissipation.
- Its mechanical properties are superior, including high strength, impact resistance, anti-aging, and crack resistance.
- The smooth interior of the pipes reduces fluid friction, which in turn can increase the flow rate by up to 30%.
- These products are environmentally friendly when it comes to their tightness against water.
- This type of product is both durable and lightweight hence very easy to install.
Applications of HDPE Pipes for Mining
- Water Supply and Drainage Systems: HDPE pipes are significant in the coal mining process primarily because they can provide an efficient water supply and drainage system.
- Ventilation Conduits: In mining operations, HDPE pipes serve as a main ventilation conduit enabling air to pass through either positively or negatively.
- Spray Systems: To meet varied operational needs effectively, HDPE tubes serve as spray conduits during mining processes.
- Gas Drainage Systems: These pipes are part of gas drainage systems used in mining thus ensuring that gases are safely released and managed.
