What is welded seamless wrought steel pipe

DataTime:[2016-10-18]

The welded seamless wrought steel pipe confirms to the standardization of dimensions ASME B36.10M-2004 standards for high or low temperature. The wrought pipe distinguished from steel tube, is applied for pipeline and piping system with tubular products of dimensions. The pipe DN300 has outside diameters numerically larger than corresponding sizes. Oppositely, the tube outside diameter is numerically identical to the size number for all sizes.

Welded Seamless Wrought Steel Pipe

The pipe size is identified by the nominal pipe size. So the manufacturers of seamless wrought steel pipe are based on the standardized outside diameter. The outside diameter is originally selected so that the pipes would have an inside diameter approximately equal to the normal size with a standard OD and wall thickness. Though there is little relation between standard thickness OD and nominal size, the pipe manufacturer proceeds on the basis of an OD corresponding to the nominal size.

ASME B36.10M-2004 Standard covers the standardization of dimensions of welded and seamless wrought steel pipe for high or low temperatures and pressures.

The word pipe is used, as distinguished from tube, to apply to tubular products of dimensions commonly used for pipeline and piping systems. Pipe NPS 12 (DN 300) and smaller have outside diameters numerically larger than their corresponding sizes. In contrast, the outside diameters of tubes are numerically identical to the size number for all sizes.

The size of all pipe is identified by the nominal pipe size.The manufacture of pipe NPS 1/8 (DN 6) to NPS 12 (DN 300), inclusive, is based on a standardized outside diameter (OD). This OD was originally selected so that pipe with a standard OD and having a wall thickness that was typical of the period would have an inside diameter (ID) approximately equal to the nominal size. Although there is no such relation between the existing standard thickness — OD and nominal size — these nominal sizes and standard ODs continue in use as "standard", The manufacture of pipe NPS 14 (DN 350) and larger proceeds on the basis of an OD corresponding to the nominal size.
