PE mining pipes have both the characteristics of general polyethylene pipes and their own features: light weight, long service life, and fast construction; Strong corrosion resistance and superior mechanical properties; Low noise level; Easy installation and good sealing performance; The flame retardancy and anti-static performance meet national standards. Universal pipe products can be used for water supply, drainage, spraying, positive pressure ventilation, negative pressure ventilation, and gas extraction in underground mines. The pressure used for universal pipes cannot exceed 1.6MPa.

• Has excellent conductivity and flame retardancy.

• The small coefficient of thermal expansion greatly improves the stability and reliability of pipeline operation.

• High toughness is a type of pipeline with excellent impact resistance and seismic performance.

• Good sealing performance.

• It has good flexibility, can be laid in a winding manner, has few pipeline connections, is easy and reliable to install, and can save a lot of construction costs.

HDPE mining pipes are mainly used for underground water supply and drainage, ventilation, coal slurry transportation, and gas drainage in coal mines.

• flange connection

  According to the standard working pressure, there is no need for rubber gasket sealing. When connecting, tighten the bolts evenly to ensure that the pipeline is fully in contact and tightened. Flange connection is suitable for places with high gas concentration, and must strictly comply with the safety operation regulations on the construction site.

• Hot melt docking

  Before welding, use a special tool to clean the pipe mouth, heat and melt the pipe mouth, and apply pressure to the pipe mouth to make it straight and form a uniform flange at the joint. Suitable for pipes of equal caliber.

• Socket connection

  Before welding, clean, dry, and oil-free the end faces of the pipes and fittings. Use hot melt welding tools to heat the pipes and fittings simultaneously, and then quickly and evenly insert them into each other without rotation, forming a uniform flange at the joint.

• Attention

  Hot melt welding should be completed above the well and is prohibited from being carried out underground in coal mines!
