The most popular process for large diameter pipe uses a longitudinal seam weld. Seamless Pipe Plug Mill Process. This process is used to make larger sizes of seamless pipe, typically 6 to 16 inches (150 to 400 mm) diameter. The tube is rotated through 90 for each pass through the plug mill to ensure roundness. The tube is then passed

It worked by passing flat bars of iron in between a set of rolls to form a plate, then a set of grooved rolls to create slits. The slitting mill was later adapted to form roll hoops for barrels. The modern roll forming process came along in the late 1700s, when a man named Henry Cort patented his use of grooved rolls for forming iron bars.

This comes in two forms: structural and seamless. Structural extruded tube is made by the porthole process, and for that reason is sometimes referred to as "porthole.". Seamless is made by the seamless extrusion process. Generally speaking, seamless extruded tubes are a little more expensive, which might push you to specify structural.
