Carbon Steel Pipes

Carbon steel pipes include seamless and welded constructure. Seamless steel pipes are mainly used for liquid transport, and are applicable to transport liquid, gas, oil, and mechanical propose. Welded pipes are lower production cost and raw materials availability. The common carbon steel pipes are ASTM or API 5L seamless steel pipes, SSAW pipes, ERW steel pipes, and LSAW pipes.

Carbon Steel Pipes FAQs

Q 1. How Are Carbon Steel Pipes Made?

A.

Carbon steel pipes include seamless and welded pipes.

Seamless steel pipes are made from a round and robust piece of steel known as a billet. The billet has to be heated first, then stretched and finally pushed or rolled over a frame or form until the pipe is hollow.

Welded steel pipes are made from steel plates and steel strips. These strips and plates are made by moving steel loops and coils with a proper thickness gauge to form a leveled material. The flat leveled material is then measured and cut to the desired lengths.

Q 2. What's The Difference In Applications Of Seamless And Welded Steel Pipes?

A.

Seamless steel pipes are used for specific applications because of their unique properties such as uniform strength distribution, non-welded joints, and their ability to withstand high temperatures, pressure capacity, high quality, better weight limit, and many more.

Welded steel pipes are widely used in several industries because they are cost-effective. They can also be manufactured in different lengths and welded from different tubing shapes. Application is entirely dependent on the use and other related factors.

Q 3. How To Choose Pipes, Seamless Or Welded?

A.

With the insight provided here, you now have the relevant knowledge to help you settle for the right pipe. It is also imperative to remember that quality overrides quantity, so plan and purchase seamless steel pipe if required and consider welded pipes if all factors favor it. In a nutshell, environmental factors and the intended use determine the best pipe.
