Seamless pipe
Seamless tubes are made of solid steel in the form of sheets or rods, forming a solid round shape called a "billet", which is then heated and cast on a shape such as a perforated rod to form a hollow tube or shell. Compared to other pipe manufacturing process methods, such pipes are known for their ability to withstand pressure more efficiently, as well as being fast and cost-effective. Seamless pipes are commonly used in natural gas pipelines as well as in pipelines transporting liquids. Because seamless tubes can withstand high pressures, they are also widely used in high-pressure applications, including refineries, hydraulic cylinders, the hydrocarbon industry, and oil and gas infrastructure.
In contrast to other types of pipes, seamless pipes do not require any welding or joints and are simply formed from solid billets, which increases their strength and other characteristics including corrosion resistance. According to ASME, these pipes can withstand mechanical stress more efficiently than welded pipes, known as non-seamless pipes, and have higher working pressures.
In general, the application of seamless pipe depends on the thickness of the pipe wall. Producing pipes with thicker walls requires higher temperatures, which reduces deformation resistance and leads to greater deflection.
