Internal Epoxy Resin Steel Plastic Composite Pipe Antistatic Corrosion Resistance
Description of Composite Steel Pipe with internal Epoxy Resin (EP) and Polyethylene (TPE) for external 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
