Tubes for high pressure service are usually made with which type of construction?

For high-pressure service, tubes are typically made using seamless construction. This method of fabrication involves forming the tube from a solid round billet that is heated and pierced to create a hollow cylinder. The seamless design eliminates the presence of welds, which can be potential points of weakness under high pressure. As a result, seamless tubes provide enhanced structural integrity and reliability in high-pressure applications.

Seamless construction is particularly advantageous in industries where the pipes must withstand high levels of stress and pressure, such as in oil and gas, chemical processing, and power generation. The absence of seams reduces the risk of failure due to weld defects and enhances the overall safety and performance of the piping system. This is why seamless construction is the preferred choice for high-pressure service compared to other designs.
