Process:

The production steps of the 3LPE coating line mainly include the following steps:

Pretreatment: Pretreatment operations such as cleaning, rust removal and drying are performed on the steel pipe to increase the adhesion of the coating. These operations can be carried out in pre-treatment devices, such as pickling, sandblasting, mechanical rust removal and other methods.

Spraying: Spray PE anti-corrosion material on the pre-treated steel pipe. Spraying can adopt electrostatic spraying, fluidized bed spraying, mechanical spraying and other methods to achieve uniform and continuous coating.

Curing: The sprayed steel pipe enters the curing device for heating, melting and solidification. This can take the form of hot air circulation, radiant heating, etc., to form a tight combination between the PE anti-corrosion layer and the surface of the steel pipe.

Cooling: The solidified steel pipe is cooled so that it gradually cools from the molten state and returns to room temperature. This can take the form of natural cooling, water cooling, etc.

Cutting: Cut the cooled steel pipe to the required length. Cutting can be done by mechanical cutting, laser cutting, etc. to obtain the steel pipe of the required length.

Inspection: Conduct quality inspection on the cut steel pipes to check whether there are any defects or problems in the coating. This can be done through visual inspection, instrumental testing, etc.

Packaging: Pack the inspected steel pipes for subsequent use or transportation. This can take the form of manual packaging or automated packaging.

Product Features:

Efficiency: Using advanced production technology, continuous and efficient pipeline production can be achieved.

High degree of automation: Equipped with an automated control system, it can automatically control spraying, curing, traction, cutting and other links, reducing manual operations and improving production efficiency and product quality.

Good coating quality: Using electrostatic spraying technology, the thickness and uniformity of the coating can be accurately controlled. At the same time, three layers of PE anti-corrosion coating can be sprayed, which improves the anti-corrosion performance and life of the pipeline.

Strong adaptability: Suitable for steel pipes of different specifications and materials. In addition, it can be customized according to customer needs.

Environmental protection and energy saving: The pollution and energy consumption generated during the production process are low, which meets the requirements of environmental protection and energy saving.

High safety: Safety protection measures are adopted during the production process to ensure the personal safety of workers and the safety of equipment.
