Carbon steel seamless pipe has, as its name implies, no longitudinal weld seam. It is, in essence, one solid homogeneous piece of steel. A solid billet is simply heated and then stretched over a series of mandrels until the pipe has achieved its desired diameter and wall thickness. Typically carbon steel seamless pipe of fourteen inches and greater in diameter are rolled from shells which expand the diameter and reduce the wall until the desired dimensions are achieved. Sizes smaller than fourteen inches in diameter are typically stretch reduced whereby the diameter is gradually reduced and the wall relatively increased via a series of rolls.  

 

A333 carbon steel seamless pipe is the part of standard covers wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures. A333 carbon steel seamless pipes shall be made by the seamless or welding process with the addition of no filler metal in the welding operation.

 

There is also a cold forming process for seamless pipe production, but such manufacturing processes are typically reserved for different alloys. Being that there is no seam, A333 carbon steel seamless pipes are typically used in high pressure applications.You may kindly float in your prestigious inquiry, so that we could try to immense business relations with your company or serve the most efficient or professional manner as we always do.
