Internal Epoxy Resin Steel Plastic Composite Pipe External Polyethylene
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 this 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).
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
Size:SP(W)-TEP(PE)-KM 295/ DN 48～1016MM
SP(H)-TEP(PE)-KM 295/ DN 48.3～1118MM
