Seamless steel pipe (SMLS) is formed by drawing a solid billet over a piercing rod to create the hollow shell, without welding or seam. It is suitable for bending and cutting. The advantage of seamless steel is the ability of withstanding higher pressure.
ASTM A106 is seamless steel pipe specification for high-temperature service. The pipe is commonly used in the construction of power plant, boiler, firefighting pipeline and ship where the piping must transport fluids and gases in higher temperatures and pressure levels.
