Steel Pipes Application » Sewage Pipes

A hollow cylinder or tube for transporting liquid wastages is called sewage or sewer pipe. Sewage system cleans water containing various waste, thus the sewage pipes are exposed to continuous corrosion and pressure. Steel pipes can resist to various chemical effects and is the most universally used pipes available in market. Since the pipes are coated with sturdy metals, these pipes are best suitable for sewerage application. Such pipes are available in a range of proven external coatings to suit all types of ground conditions and above ground applications. They can be also used in pumping stations and treatment works.

Why steel sewage pipes?
Sewage pipes made of steel sustain gravity or high pressure, are corrosion resistant and minimizes embedded requirements. These pipes are available in full range of diameters and fittings, to suit different ground conditions and pressure ratings. Simple and quick to install, high strength allows these pipes to cope with uneven longitudinal loading and make them resistant to damage and disruption.
