The strength of spiral steel pipe is generally higher than that of straight welded pipe. It can produce welded pipe with larger diameter with narrow blank and different diameter with the same width blank. The double-sided submerged arc welding technology is adopted for the large-diameter spiral steel pipe.
Carbon steel pipe starts out by arriving at the pipe mill in the form of either a billet (basically a large solid steel bar) or a coil (imagine a roll of toilet paper made out of steel). Depending on the manufacturing method used by the mill, these billets or coils will be processed to yield the finished end product.
Carbon Steel Pipe Omega SteelTypically seamless carbon steel pipe 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.

Spiral welded pipe is manufactured from steel coil. The coil is unwound and then welded while it is being turned into the shape of the pipe. Changing the angle of the spiral and the thickness of the coil is all that is needed to change from one pipe size to another. The two sides of the double submerged arc weld penetrate the full thickness of the steel to ensure the strength of the finished pipe.

When the large diameter spiral steel pipe weld defects corresponding parallel exists, its extended risk is also smaller because of the smaller spiral weld force. This has proved superior to plastic deformation capacity of spiral welded longitudinally welded pipes, blasting mouth is generally confined to a pitch, which is the extension of spiral

Steel Pipe Dimensions large diameter spiral steel pipe steelsamp; Sizes Chart (Schedule 40, 80 Pipe In this standard, the pipe Outer Diameter smaller than 12.75 in (NPS 12, DN 300), pipe actual diameters is larger than NPS (Nominal Pipe Size)or DN (Nominal Diameter). On the hand, for steel tube dimensions, the actual outside diameter same with pipe number for all sizes.
If straight seam steel pipes are used, general large pipes are rolled up with steel plates and welded directly. A larger steel plate is needed. This greatly increases the manufacturing difficulty. Therefore, spiral pipes will be used for larger pipe diameters. The above is some knowledge about straight seam steel pipes and spiral steel pipes.
