Spiral Welded Steel Plastic Composite Pipe Epoxy Resin Powder Coated GB T 2914
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).
size:HOSP-TEP(PE)-KW(-0.097)/101.6～1118
size:DN100mm～DN1000mm
Pressure Grade
Pipeline for gas drainage in underground coal mine, bearing pressure - 0.097 - 1.0 MPa.
Performance characteristics
1) 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
2) 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.
3) Connection modes are diversified and easy to construct: Flange connection and butt welding connection can be used for products. Connection modes are diversified and installation is convenient.
