Trends To Seamless Steel Pipes

Manufacturing and applications:

Seamless pipes can be manufactured using various different methods, which is very much dependent on the diameter required, or the ratio of the diameter to the thickness of the wall. In general, the manufacturing process of seamless pipe starts with raw steel being cast into a more workable format – a hot solid billet. This is then stretched out and pushed or pulled over a form. This hollow pipe then undergoes an extrusion process whereby it is forced through a die and mandrel. This works to increase the inside diameter and reduce the outside diameter.

Seamless steel pipe is regularly used in the transportation of fluids such as water, natural gas, waste and air. It is also regularly required in many high-pressure, high-corrosive environments such as in the oil & gas, power generation and pharmaceutical industries.

Advantages:

Strength: Seamless pipes come with the obvious advantage of having no seam and therefore no chance of a weak seam. This means that typically, seamless pipe can withstand 20% more working pressure than welded ones of the same material grade and size.

Resistance: The lack of seam means that seamless pipe can offer higher resistance to corrosion because there is less opportunity for things like impurities and defects that can more commonly occur along a weld.

Less Testing: It goes without saying that seamless pipes don’t require testing for weld integrity – no weld means no test!

What are the expected trends related to seamless steel pipes?

Seamless steel pipes are omnipresent and can be located under and inside a residential complex, laboratory, commercial complex, and industrial walls. Fluids such as water, natural gas, etc., are transported utilizing these pipes.

Growing carbon emission has been a major concern for manufacturing industries. As a solution to reduce these emissions, sequesteration technology has been adopted, where carbon emissions are stored underground.

These specifications have been drawing attention towards seamless steel pipes, which possess all these properties. Demand for seamless pipes is expected to surge for use in underground storage systems.
