Underground Steel Plastic Composite Pipe Extruded Polyethylene Coating

Underground Steel Plastic Composite Pipe Extruded Polyethylene Coating

Description of Long service life Polyethylene/ (PE) steel Plastic Composite Pipe for underground coal mine strong coating adhesion

Mine pipe refers to a product specially developed for special underground environmental conditions, which has the advantages of flame retardant, antistatic, corrosion resistance, long service life and strong safety. It is mainly used in five systems: mine drainage pipe (KS), mine grouting pipe (KJ), mine positive pressure air pipe (KFZ), mine negative pressure air pipe (KFF), mine gas drainage pipe (KW).

Properties of Polyethylene powder

Coating adhesion is strong: physical method is used for advanced treatment of the base pipe. The pretreatment meets Sa2.5 standard. Microcomputer is used for automatic preheating control and production. Coating adhesion is higher than national standard.

Flame retardant and antistatic performance is good: flame retardant and antistatic indicators meet the requirements of underground gas drainage pipe indicators. Flame retardant: The arithmetic average of flameless combustion time is less than 3S and the maximum is less than 10s; the arithmetic average of flameless combustion time is less than 20s and the maximum is less than 60s. Antistatic: internal and external surface resistance ≤1.0×106Ω

Good hygienic performance, low fluid resistance: in line with the drinking water standards of the Ministry of Health, no fouling, no breeding of microorganisms, no secondary pollution of fluids. The inner wall is smooth and the conveying efficiency is high.
