Seamless steel pipe is primarily used for which type of service?

Seamless steel pipe is primarily used for higher pressure service due to its structural integrity and strength. The manufacturing process for seamless pipes involves extrusion or rotary piercing, which creates a pipe without any welded joints. This characteristic makes seamless pipes particularly well-suited for applications where high pressure could lead to failure in welded joints.

In high-pressure environments, the risk of stress concentration at welds in welded pipes can pose a failure risk. Therefore, seamless pipes provide greater assurance that the material will withstand higher pressure conditions. They are commonly utilized in industries such as oil and gas, chemical processing, and power generation, where the pipes must handle fluids or gases under high pressure.

Other options may refer to different attributes or applications, but they do not reflect the primary purpose of seamless steel pipes, which is to cater to high-pressure scenarios effectively and safely.
