The difference between plastic-lined steel pipe and steel-plastic composite pipe

The difference between plastic-lined steel pipe and steel-plastic composite pipe

1. Toxicity

The steel-plastic composite pipe is a five-layer composite pipe. The inner layer is non-toxic and non-polluting, but the main material of the inner layer of the plastic-lined steel pipe is epoxy resin powder or PE powder, which contains harmful ingredients.

2. Use environment

Steel-plastic composite pipes are smooth and not easy to scale, and can be used not only in cold water but also in hot water. However, the inner wall of the plastic-lined steel pipe is uneven and not smooth, which causes the scale to accumulate, which breeds bacteria. It will be thermally expanded when used in hot water systems. Its outer wall does not have an anti-corrosion layer, and it is more likely to rust. Thus affecting the service life.

3. Price

The price of steel-plastic composite pipes will be slightly more affordable, because the workmanship of plastic-lined steel pipes is complicated, so the overall price will be higher than that of steel-plastic composite pipes.
