Plastic Coated Pipe with Good Corrosion Resistance

Plastic coated steel pipe is also known as plastic coated pipe. It is a kind of composite pipe which is widely applied in many fields such as agriculture, mining and transportation. Plastic coated steel pipe is characterized by good corrosion resistance and excellent mechanical performance. This product is especially fit for transporting the fluid which contains corrosive chemical compositions. Plastic coated steel pipe is also suitable for the harsh using conditions of underground. We strongly recommend this product because it is much safer and more durable than the other pipelines.

Plastic coated steel pipe can be connected with flanges.

We have a large number of plastic coated pipes in stock.

Plastic coated steel pipe is available in various colors, such as yellow, black, green and blue.

Our company has the ability to produce various large diameter pipes.
