How steel pipe is made - material, manufacture, making seamless pipes manufacturing how to produce seamless

Design Raw Materials The Manufacturing Process Quality Control There are two types of steel pipe, one is seamless and another has a single welded seam along its length. Both have different uses. Seamless tubes are typically more light weight, and have thinner walls. They are used for bicycles and transporting liquids. Seamed tubes are heavier and more rigid. The have a better consistency and are typically straighter. They are used for things such as gas transportation, electrical conduit and plumbing. Typically, they are used in instance See more on madehow Production of Seamless Pipes IspatGuruThe manufacturing processes for seamless pipes were developed towards the end of the nineteenth century.
