Pipes and tubes are tubular structures, which are designed to transmit fluids and gases over long distances. They are both similar products but, pipes can be utilized in high-pressure applications while the latter is preferred for moderate to low-pressure systems. Both these two specifications has its own advantages, and flaws which gives consumers a diverse choice to select the product suitable for them.
A seamless pipe is produced utilizing a single piece of sheet metal. This range of components are very strong and diverse due to the unique raw materials used while producing them. They don’t require any welds or joints which, enables them to have enhanced tolerances. They are formed by placing a hot billet over the steel, which pierces it and forms, an opening creating a unique design. This product range can be utilized in stress-induced environments where corrosion levels are at the highest. Apart from this, they perform well under extreme pressures and elevated temperature systems where other pipes wouldn’t readily suffice. Each of these modules can be availed in different shapes, namely square, circular, rectangular, and hydraulic. All these different shapes come with unique properties and can be used across different applications.
There are some key differences, which help in differentiating the two pipes.
Different quality of steel is utilized to produce these marvelous structures. Since they don’t possess any welds or joints, they are formed utilizing billets. These billets are heated at high temperatures, which form into shells. The shells are later rolled on a mandrel and pushed onto the steel. In the reducing mill, the tube is customized giving, it different dimensions and wall thickness. After they are cooled, they are cut into fixed lengths and later furnished to give it enhanced mechanical properties and enhanced connection systems.
A seamless pipe is produced utilizing a unique process while the cold forming of a sheet into a tubular structure produces electric resistance welded pipe. Both these pipes can be utilized in different applications however the ERW pipe is more susceptible to intergranular corrosion due to welds used while producing them. Furthermore, they are not preferred in high-pressure applications compared to the single sheet pipe ranges. An ERW pipe is, however, very economical compared to an extruded.
Yes, they are stronger than welded sections making them more expensive. The overall quality of the pipe far exceeds the quality of the seam joint modules. This allows them to be used in high-pressure applications in different industries. Their ability to withstand harsher environmental conditions also gives them enhanced strength making them highly desirable. Furthermore, their availability in the market is low as they are produced using high-quality raw material.
A welded pipe has seams or welds which, make them considerably weak. These joints have the potential to collapse and subsequently lead to leakage and failure of the system. This structural flaw, however, has been rectified and improved over the years, which has allowed them to be used in higher-pressure applications. However, to be on the safer side many high-risk industries prefer not to use a seam joint pipe within their operation.
