Light Weight Steel Plastic Composite Pipe Strong Coating Adhesion For 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:HOSP-TEP(PE)-KW(-0.097)/101.6～1118
size:DN100mm～DN1000mm
Pressure Grade
Pipeline for gas drainage in underground coal mine, bearing pressure - 0.097 - 1.0 MPa.
Performance characteristics
1) Internal and external coatings can be made of different materials or colors according to customer's service environment and requirements.
2) 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.
