Epoxy Coated Carbon Steel Pipe For Special Underground Environmental Conditions
Description of Good hygienic performance Epoxy resin (EP) coated composite steel pipe for underground coal mine low fluid resistance
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:SP(W)-TEP(PE)-KM 295/ DN 48～1016MM
SP(H)-TEP(PE)-KM 295/ DN 48.3～1118MM
Pressure Grade
suitable for Pipeline’s pressure not more than 10 MPa
Carried Standard

Performance characteristi
aracteristi
High pressure, good mechanical properties: the base pipe is reinforced welded steel pipe or high pressure seamless steel pipe, the inner and outer surface of polyethylene or epoxy resin anticorrosive treatment, the perfect combination of steel pipe and plastic pipe. Continued the advantages of steel pipe, its mechanical strength is very high,
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
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.
