Welded steel pipes are pipes that have seams visible on the surface and are welded after being bent into round and square shapes by grappling and stretching steel strips or plates. Welded piping made from steel blanks is either steel plate or strip steel.
The Evolution of the concept of welded steel pipe stems from its origin in the 1930s, where it stayed as a typical boast due to improvement in the quality of strip, continuous rolling production and a substantial advancement in welding and inspection technology. Moreover, the number and design of welded steel pipes developed, while the seamless ones were replaced by welded pipes in numerous fields. The weld pipe of low-cost and high productivity can be substituted by the length of seamless pipe.
These find application in three situations; the pipe being welded on the surface, the pipe being welded inside, or the pipe being weld from both sides. The element here is the spot where they all get out of seam.
- Different than standard carbon steel, the welded version of super duplex pipe has a superb resistance to corrosion and wear and tear in severe chemical environments.
- Rotate less Through-Sleeved Pipe with Welded Fitting and Stainless Steel Movable yoke
- The temperature resistance of the welded nickel alloy tubing is suitable for high and mid-temperature applications.
Use of Welded Pipes
Today we can see welded pipes everywhere! Just name an industry and they would most likely use welded pipes. Due to welded pipes useful abilities to have broader dimensional opportunities than seamless steel pipe, they then are able to fit in situations where corrosion resistance is more of a requirement than pressure minimization.
- The coiled welds and joints of the tubes and pipes provide a better cost-effectiveness as compared to the same sizes of seamless versions.
- Welding pipes is the leading sensed sort of utilized in leading pipeline projects, and they can be applied in the most number of infrastructures for water and sewerage lines.
- The pipeline work is quite of a challenge in particular for oil and gas trades – they are used to ship the oil and gas from oil fields to overseas terminals and in refineries.
- With the option of welded pipes for example, scaffolding, street poles and glass facade in building structures can be created, such as stadium roofs, metro and railway stations.
- The chemical application of welded steel pipe which is an important end-user utility where they can construct chemical processing lines, industrial sheds and mechanical structures. In other sectors, they are automotive industry, machine-building, metallurgical centers, shipbuilding and energy sector.
Advantages of Pipes
- Cost: Piping welded is the lowest cost pipe type among all of them.
- Availability: The manufacture of welded pipe by modern technologies is simpler ,an institution may have already it in stock and they don’t require long procurement periods for this now.
- Consistency: Due to the fact that welded pipes tend to have thinner sides as compared to the seamless versions, the thickness remains much the same which is a better feature. This is because the starting of welded pipe is industrial process and it is based on annihilation with flat sheet of steel and this step is rather critical.
- Surface quality: In most cases, the surface a welded pipe connects is usually very smooth hence the chance of corrosion is greatly limited.
