Oil Pipeline 3LPE External Coating Plant Equipments Powder Coating Production Line

3PE anti-corrosion production line as a high technical barriers to high-end equipment, and bending 3PE anti-corrosion production line because of the particularity of bending processing technology, the current domestic enterprises have the ability to produce, or have the ability to make technological breakthroughs fewer enterprises, of which Qingdao Huashi Machine Co., Ltd. and other manufacturers, can be said to be the leader in this industry. The bending pipe winding 3PE anti-corrosion production line manufactured by the company also has its advantages beyond the general.

Huashida 3PE anticorrosive production line adopts the most advanced anticorrosive treatment technology and spraying process to ensure that product quality reaches the international leading level. 3PE anti-corrosion layer is composed of epoxy powder primer (FBE), adhesive layer and polyethylene layer, this structure can not only provide excellent mechanical properties and anti-corrosion properties, but also extend the service life of the pipeline, suitable for a variety of complex working environments. Walstar constantly innovates in technology research and development, and strives to provide customers with the best quality anti-corrosion solutions.

The outer anti-corrosion layer of 3PE steel pipe in this production line is a kind of anti-corrosion structure composed of the bottom epoxy powder, the middle layer adhesive and the outer layer polyethylene composite. It has the advantages of high mechanical strength, excellent electrical insulation performance, high mechanization degree of production line, relatively stable process parameters, no pollution to the environment, etc., to ensure the corrosion resistance of the steel pipe during use. This technology has a wide range of applications in the field of pipeline transportation, which can extend the service life of steel pipes and improve the reliability of pipeline systems.

Automatic steel pipe bends fittings 3LPE coating line

is an advanced solution to apply 3LPE/FBE external coating on steel pipe bends, which are widely used in pipeline systems for the transmission of oil, gas, water and other fluids.They have highly resistance to corrosive from chemicals, moisture, harmful environment etc.

Winding anticorrosive steel pipe parameters

Curvature radius: 4-6 times D
Elbow angle: 15-90 degrees.
Steel tube wall thickness: 8 mm -12 mm
Epoxy powder thickness: greater than 170 um
AD copolymer adhesive thickness: 170-250 um
PE layer thickness: 2.5 - 3.7 mm

Russian SPV Steel pipe company, originally a steel pipe only business, because the Russian market has a large number of anti-corrosion steel pipe demand, they decided to invest in the construction of a production line for pipeline anti-corrosion. After signing the order with Walstad last year, Walstad prepared its production equipment for shipment according to the schedule requirements.

Other manufacturers of bending pipe winding 3PE anti-corrosion production lines, some processing range between Φ630-820mm, must have manual assistance on the line, flame secondary baking, PE strip has warped edge, low production efficiency; Although some processing range sheath to Φ630-1220mm between, but need to use bending waste heat for winding operation, the use of rotary center type push head, replacement of pipe diameter is complicated, push head cantilever is too long walking instability; Although some use mechanical electrostatic spraying, a high degree of automation, but the range of machined pipe diameter is really small, can only be between Φ300-800mm. The pros and cons are obvious.

The traditional 3pe anti-corrosion production line generally has three forms, whether it is the double-layer epoxy powder Ownchart operation method, or the manual heating installation method of polyethylene heat shrink sleeve, there are obvious defects to a certain extent. How to avoid all the above defects has become the direction of technological development, and it is the purpose of achieving high-quality anticorrosion in the real sense.
