Painted Steel Pipe

Coated steel pipes use steel pipes as the base pipe, plastic powder (such as epoxy resin) as the coating material, a plastic layer on the inner surface, and a plastic layer or other material anti-corrosion layer on the outer surface. The steel pipe coated by the composite pipe is also called plastic-coated steel pipe.

In short, in addition to color, when purchasing plastic-coated steel pipes, you also need to pay attention to factors such as pipe size, material, thickness, and connection method. It is recommended to purchase products that have relevant production licenses, quality inspection reports and comply with national standards to ensure their quality and effectiveness.

Transportation and storage

Package

Each coated steel pipe should be covered with envelopes at both ends to prevent dust from entering the pipe. The coated steel pipes with envelopes should be packed in hexagonal bundles. The outer coating should be packed with a protective layer. When bundling, appropriate materials should be used to separate the coated steel pipes from the two bundled steel strips to prevent scratches on the coating. layer.

transportation

It should not be thrown or hit violently during transportation.

Storage

Coated steel pipes should be stacked upright in a cool place. When stored in the open air, it must be covered with a cover. It should not be stored outdoors in direct sunlight or cold places for a long time. The storage temperature is -15 ℃ ~ +40 ℃.
