The advantages and disadvantages of seamless steel pipe

Seamless pipe is a steel, which is hollow, there are many different shapes, to facilitate the selection and use. Seamless steel tube is made of steel ingots or solid tube through the perforation of capillary, and then through a series of industrial production processes to complete. Seamless steel pipe with a hollow section, so that can flow into a lot of water and the like liquid, steel and round steel and other solid steel is not only very hard, King Penguin material is relatively light, is an economic section steel, In many aspects can be used, such as oil drill pipe, car drive shaft, bicycle frame and construction of steel scaffolding. Seamless steel pipe has the advantage of high pressure, good toughness, pipe length and interface less. But the general price of such steel is relatively high, it is easy to corrosion, to be ah yo regular replacement. Seamless steel tube under the same weight light weight. Seamless steel pipe manufacturing ring parts, can improve material utilization, simplify the manufacturing process, saving materials and processing time advantages.

Welded Pipe vs. Seamless Pipe

Welded vs. seamless. It’s a debate that’s been around for a long time, and it’s still going strong today.

So when your next project arrives, what side of the debate will you fall on? Will you choose a welded steel pipe, a welded carbon pipe? Or will you go with one of their seamless counterparts?

Here are some of the advantages of both types of pipes to help you make your decision.

Advantages Of Welded

  • Welded pipes are typically more cost effective than their seamless equivalents.
  • Welded pipes are usually more readily available than seamless. The longer lead time required for seamless pipes can not only make timing problematic, but it also allows more time for the price of the materials to fluctuate.
  • The wall thickness of welded pipes is generally more consistent than that of seamless pipes.
  • The internal surface of welded tubes can be checked before manufacturing, which isn’t possible with seamless.

Advantages Of Seamless

  • The main perceived advantage of seamless pipes is that they don’t have a weld seam. Traditionally, the seam of welded pipes has been viewed as a weak spot, vulnerable to failure and corrosion. For many years, this fear was probably justified. However, in recent years improvements in the manufacturing process for welded steel pipes and other welded pipes have boosted the strength and performance of the weld seam to levels indistinguishable from that of the rest of the pipe.
  • Seamless pipes provide peace of mind. Although there should be no issues with the seams of welded pipes supplied by reputable manufacturers, seamless pipes prevent any possibility of a weak seam.
  • Seamless pipes have better ovality, or roundness, than welded pipes.
