GB T 6554 Steel Plastic Composite Pipe Underground Steel Pipe Coating Anti Aging

Description of Internal Epoxy Resin (EP) and Polyethylene (TPE) for external for Steel Plastic Composite Pipe for Coal Mine

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

Inspection Code for Safety Performance of Plastic Pipe Used in Coal Mine

GB T 6554 Steel Plastic Composite Pipe Underground Steel Pipe Coating Anti Aging

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, impact, bending, pressure and strength and other external forces have a strong bearing capacity.

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.

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.
