Coal Mine Steel Plastic Composite Pipe Internal EP External TPE GB T 6554
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).

SP(H)-TEP(PE)-KM 295/ DN 48.3～1118MM
Pressure Grade
suitable for Pipeline’s pressure not more than 10 MPa
Carried Standard
Inspection Code for Safety Performance of Plastic Pipe Used in Coal Mine
The properties of epoxy resin powder for coating meet the requirements of the following table:

Chemical corrosion resistance, weathering resistance and aging resistance are very high: the coating can prevent metal oxidation, and has the corrosion resistance of acid, alkali and salt. The product has excellent anti-aging performance, and its service life is much higher than other pipes. The product can be painted with flange to ensure the anticorrosion effect of the whole pipeline.
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.
