Product Description

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).
