Municipal pipeline laying method – overhead laying

● Introduction:

Laying above the ground is generally called overhead laying, which is mostly used in urban edges, areas without residential buildings and industrial plants.

● Advantages and disadvantages:

Overhead pipelines are not corroded by groundwater, have a long service life, are easy to ensure the slope of the pipeline, and have a small amount of earthwork, making maintenance and management convenient.

However, since the pipeline is exposed on the surface, it is easy to oxidize and corrode, and is vulnerable to natural disasters such as ice and snow, floods, and even human activities.

● Suitable pipeline types:

gas pipelines, thermal pipelines, etc.
