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

Connection modes are diversified and easy to construct: Flange
connection, fast joint connection, socket connection, bimetal
connection and butt welding connection can be adopted for the
products. Connection modes are diversified and installation is
convenient.
Internal and external coatings can be made of different materials
or colors according to customer's environment and requirements.
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.
