Many people affirm the use of seamless pipes, which are often used to transport gases and chemical liquids. But many people don’t know how it is made. And what should we pay attention to when the factory purchases seamless steel pipes.
Seamless piping starts with a solid cylindrical chunk of steel called a billet. While still hot, run the billet through the middle with the mandrel. The next step is to roll and stretch the hollow billet. The billets are rolled and drawn to the length, diameter and wall thickness specified by the user.
An important thing to note when specifying piping products for a project is that the codebooks that engineers use to guide customer-written specifications (such as those provided by ASTM, ASME, ANSI, and API, etc.) only list piping grades without reference to Whether they are produced by ERW or seamless tube manufacturing. Not all grades can be produced in either way.
The above are the manufacturing and purchasing habits of seamless steel pipes. If you want to know more, please contact us.
