How can we get a perfect alternatives of steel pipes to build our society? This means what kind of pipe has all good futures of steel pipe. Besides that, it should also have its own advantages which the steel pipe can not compare with.

A corrugated pipe is a tube that is completely surrounded by parallel ridges and grooves. The ridges and grooves on the surface of it is perpendicular to the centerline of the pipe and are equally divided. In the case of non-excavation, the raw material of the bellows may be iron steel or high density polyethylene (HDPE) plastic.

Plastic containers contain many chemicals, some of which have been identified as potentially hazardous. High density polyethylene, which is also known as HDPE, is a tougher and more durable plastic than many other polymers. This durable plastic is used in a variety of applications.

There are two types of plastics, thermoplastic and thermoset polymers. Thermoset polymers can only be melted and molded once and remain solid once cooled. Thermoplastics can be repeatedly melted and shaped to be recycled. Both PVC and HDPE are thermoplastics that have much in common.
