DETAILS

3 Layer PE Steel Pipe Anti-Corrosion Coating Machinery

3LPE coating line is to make anti-corrosion of kinds of steel pipes, such as single layer FBE, double layer FBE, double layer PE, double layer PP and 3PE. Outer protective layer of coated pipe has a high mechanical strength, excellent electrical insulation performance. The merits includes high degree of mechanization, process parameters stable, not pollute the environmen. It is to prolong the pipeline life of use from 5-10years to 50-100years.

              

                                                    Application

The three-layer PE process, with the epoxy powder coating as bottom layer, binding and bundling through polyethylene PE and adhesive, is widely used in anticorrosion of steel pipes, and applied to the oil, natural gas, chemical material, water pipelines.

The thickness of the glue layer is greater than 85 mm, the transmission is stable and reliable,and the safety guarantee for the long-term operation of the equipment.      

Steel pipe heating equipment

Steel pipe heating equipment is used to heat pipes. It can preheat, heat and curing pipes with different technological requirements.It is used to heat the pipe from 40℃ to 60℃ before blasting, and to wipe off water, moisture and greasy dirt on the surface, which can meet the demands of rust removal.It includes intermediate burner heating and frequency heating (see intermediate frequency heating) form.The heating media of burner can be gas and diesel.Intermediate frequency heating system is mainly used to heat pipes to 180℃- 230℃ to meet the coating standard.

Steel pipe blow equipment

The internal blowing system is used to clean the dust, and sand inside the pipes by the draught fan, so that it can prevent the pollution when coating.The system includes pipe internal blowing carrier, dust collecting box, pulse back-blowing dust collector, live rotation roller, pipe stopper, etc. A set of filter-barrel type pulse back blowing dust collector is equipped on the dust collection box.

Dust treatment It is used to clean dust and abrasive on pipe surface after blasting and improve the adhesion of FBE.

Fusion Bonded Epoxy powder coating equipment and recovery system

The system includes stainless coating room, epoxy powder guns, powder coating controller, fluidization powder box,dual cyclone collecting structure,and pulse-blowback-cylinder dust catcher.

Extrusion system

It is used to extrude PE adhesive and PE protective coating, which are twined to the external wall of the pipes.The polyethylene protective coating can protect the epoxy powder coating.It can be divided into cladding type and twining type according to coating pattern and twining type can be divided into side type and upper type.

                                                

Steel pipe water spraying equipment

The water cooling system is used to cool heated piped rapidly to the temperature of 40℃-60℃, to protect its anticorrosion layer and protection layer.Water cooling system consists of water cooling room, water cooling tower, self-prime pump, centrifugal pump, pipeline, etc. There is a back water pond near cooling room.

Cutback machine

This device is used to remove pipe-end coating layer and then form a groove whose angle is below 30°, in order to joint easily.It is double-head high-efficient cutback machine. It is composed of steel brush, polishing motor, moving trolley, high efficiency dust collector etc.It is also equipped with lifting rotation roller, rocker arm etc.
