Description:
Qingdao Huashida Machinery Co., LTD. Steel elbow 3PE anticorrosive production line, mainly used in the manufacture and processing of oil and gas transportation, water supply transportation, sewage transportation, chemical transportation for 3PE anticorrosive bend (arc pipeline).
At least 16 groups of bending pipe conveying structure are arranged, the bending pipe is placed on the bending pipe conveying structure, the rotating shaft of the driving mechanism is driven by the rotating motor, and the rotating power is driven by the driving mechanism as the center. The center height of different pipe diameters is unified by the lifting device of the bending pipe conveying structure to adjust the height of the hanging roller.

Huashida outside PE inside epoxy anticorrosive pipe production equipment basic introduction
The anti-corrosion layer is crucial to the life of the buried pipeline, the same material of the pipeline, some buried in the ground for decades without corrosion, and some leakage occurs in a few years, so the need for higher anti-corrosion technology for pipeline anti-corrosion.
Pipeline anticorrosion production line composition
Huashida steel pipe anticorrosion production line is mainly composed of loading bench, rust removal transmission line, steel pipe preheating device, steel pipe shot blasting rust removal equipment, intermediate bench, rust inspection platform, return track, steel pipe internal purging device, coating transmission line, pickling equipment, medium frequency heating equipment, epoxy powder spraying device, polyethylene extruder, adhesive extruder, centralized feeding system, water cooling system, and prevention The rotten layer inspection platform, pipe end grinding equipment, pipe exit table, linear roller table, automatic coding equipment and the whole production line and corresponding equipment pneumatic, hydraulic control system, electrical control system and safety facilities.

Technological processes:
Upload pipes→pipes screw conveyor→rust removal of intermediate frequency heating→Epoxy powder coating→outer layer soli quid & polyethylene coating→cooling spray→pipes screw conveyor→grinding pipes, send→unload pipes

Huashida outside PE inside epoxy anticorrosive pipe production equipment effect
PE inside the epoxy anti-corrosion equipment, the inner layer of epoxy powder, fundamentally ensure the anti-corrosion effect of the anti-corrosion steel pipe, and then carry out the next process: The adhesive three-layer structure polyethylene anticorrosion layer combines the excellent properties of fused epoxy powder coating and extruded polyethylene anticorrosion layer, and combines the interface characteristics and chemical resistance characteristics of fused epoxy powder coating with the mechanical protection characteristics of extruded polyethylene anticorrosion layer to improve their respective properties. Therefore, it is very superior as the outer protective layer of the buried pipeline.

advantage

1, 3pe anticorrosive steel pipe has very high sealing, long-term operation can greatly save energy, reduce costs, protect the environment.
2, the construction is simple and fast, and the service life can reach 30-50 years.
3, also has good impact resistance under low temperature conditions, PE water absorption is low.
4, at the same time with high epoxy strength, PE low water absorption and hot melt adhesive softness, has a high anti-corrosion reliability, this anti-corrosion is characterized by simple production process, good anti-corrosion effect, low price, is the pipeline manufacturing industry generally recognized anti-corrosion method 2, oil and gas with three layers of polyethylene (3PE) steel pipe anti-corrosion, two layers of polyethylene (2PE) steel pipe anti-corrosion.
