As we know maximum diameters for ERW pipe usually is 457 mm 16 inch, so we can say the pipe diameters is larger than this OD are known to be large diameters pipes. For LSAW and SSAW large steel pipe:From 508 mm 20 inch to 2540 mm 100 inch. For large diameter seamless pipe also refer to the pipe that more than 16 inch or 20 inch.

We provide high-quality, leading-edge analysis of international trade issues to the President and the Congress. The Commission is a highly regarded forum for the adjudication of intellectual property and trade disputes.
Large-Diameter Welded Steel PipeLarge-Diameter Welded Steel Pipe. The large-diameter welded pipe is manufactured at the Kashima Steel Works. The steel plates are first bent into U-shapes, formed into round shapes by the O-ing press, and then have their seams submerged-arc welded. With over 90 percent of these large pipes used in energy fields such as oil and natural gas

The difference is the coil is wound at an angle, so the weld runs around the outside of the pipe in the shape of a helix. This allows for a lot more variation in diameter and thickness than ERW pipe. Spiralweld pipe is most commonly used for pipe diameters between 24 in. and 120 in. and for thicknesses of 1.0 in. or less. Manufacturing Process
Steel Pipe Dimensions & 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.

Welding performance:Average Welded Pipe and seamless steel pipe the chemical composition has a certain difference. The production of seamless steel component is only astm the basic requirements. Wall thickness and diameter:Small thin-walled pipe preferably by welding production. Large thick-walled pipe is best made with the seamless method.
