O-type Extrusion Type Anti-Corrosion Coating Production Line for 3LPE Steel Pipe
Product Description
The 3LPE (Three-Layer Polyethylene) coated anti-corrosion production line has good chemical corrosion resistance: it can resist the erosion of various chemical media, such as acid, alkali, salt, oxidant, etc. It is suitable for media transportation in different environments and prolongs the service life of the steel pipe.
O-type Extrusion Type 3LPE anti-corrosion coated steel pipe has good chemical resistance: it can resist the erosion of a variety of chemical media,,such as acids, bases, salts, oxidants, etc,suitable for medium transportation in different environments,prolong the service life of steel pipe. This kind of anti corrosive steel pipe is widely used in oil, natural gas transmission pipelines, water supply and drainage pipelines and many other fields.
Technological processes:
Upload pipes→pipes screw conveyor→rust removal→intermediate frequency heating→Epoxy powder coating→outer layer adhesive polyethylene coating→cooling spray→pipes screw conveyor→grinding pipe ends→unload pipes
