7 The general stock range for seamless and welded carbon STEEL pipes is8mm to 600mm nominal WELDED AND SEAMLESS WROUGHT STEEL PIPEASME covers the standardization of dimensions of welded and seamless wrought STEEL shows both imperial and metric units, the metric units being soft conversionsof the imperial pages 12 and 13 we have shown only metric dimensions to ASME for the more popular size have also included inside diameter ( ) and metric nominal size (DN) which are not shown in ASME NOMINAL SIZE May be expressed in metric (mm) or imperial (inch) OUTSIDE DIAMETER is shown to the nearest for outside diameters which are andsmaller, and to the nearest for outside diameters larger than We have shown the equivalentinch size underneath in brackets ( ).3. WALL THICKNESS is shown rounded to the nearest INSIDE DIAMETER is not shown in ASME , however, by using the inch measurements in ASME ,we have calculated the inside diameter( ) in inches and used the factor to convert to millimetres to the MASS (WEIGHT) is shown in kilograms per meter (kg/m) for plain end pipes.

8 These are calculated valuesusing the formula shown at the bottom of page 13 (taken from ).6. WALL THICKNESS DESIGNATIONS The wall thickness designations Standard WT , Extra Strong and Double Extra-Strong , have been commercially used designations for many years. Schedule numbers were added asa convenient designation for use in ordering pipe . Standard WT and Schedule 40 are identical for sizes up to NPS 10inclusive. All larger sizes of Standard WT have wall thickness. Extra-Strong and Schedule 80 are identical forsizes up to NPS 8inclusive. All larger sizes of Extra-Strong have wall pipe ENDS Unless otherwise specified pipe ends are normally supplied as below:-(a) Up to and including size are supplied with plain ends cut square.(b) Above sizes (except for Double Extra-Strong pipe ) are supplied with plain ends bevelled.(c) All Double Extra-Strong pipe is supplied with plain ends cut END PREPARATION(a) Bevelled ends for API STEEL linepipe are normally to API specification Angle 30 +5 -0 (b) Bevelled ends for STEEL pipe to ASTM specifications are normally to ASME Angle 30 +5 -0 METRIC CONVERSION TERMINOLOGYSoft conversionis an exact mathematical equivalent using known conversion factors from imperial to Inch to millimetres (mm) = 1 x Therefore 123/4inch x = conversion can only be applied to actual measurement, it cannot be applied to nominal conversionis where pipe manufactured to imperial sizes ( x WT in actual inches) is replaced by pipemanufactured to metric sizes ( x WT in actual millimetres [mm] ).

9 pipe is only quoted as a typical material OF MANUFACTUREMETHODS OF MANUFACTURE11 SEAMLESS PIPEIn the seamless pipe -making process tube rounds are heated in a furnace, after whichthey are pierced, then rolled by the Mandrel or Plug-Mill process into pipes and tubesof specified diameters and wall tubular products are generally hot-rolled, but can also be supplied cold-drawn(up to 273mm ) when Push-Bench process can also be used in the manufacture of seamless pipe . In thisprocess, a STEEL billet is furnace heated to the plastic state and partly punched at one endto take a mandrel. The billet is then forced by the mandrel through a series of graduallyreducing dies, until the required outside diameter has been attained, the beingdetermined by the size of the plates are first U-shaped then O-formed by ahydraulic press. The seam is welded from inside andoutside automatically by the submerged-arc expansion gives the pipe precise diameter androundness and relieves residual stresses caused byforming and WELDED pipe ( )In Australia, as in modern installations overseas, ERW Linepipe has gained increased acceptance, where Seamless Pipewas once considered essential, because of its uniform quality and dimensions, and its cost ERW manufacturing process is described below:At the pipe mill the strip is uncoiled, levelled and crop-sheared.

10 It is then trimmed on both sides simultaneously to correctwidth and immediately fed into the forming and welding line. During the process, the strip is closely checked forsurface series of cold forming rolls changes the strip progressively into tubular form with abutting edges on top. The longitudinaledges are joined by high frequency electric resistance welding. The weld is then heat treated electrically. Special devicesremove inside and outside flash from the weld to give uniform wall thickness of the welded part is then heat-treated by post annealing to ensure adequate ductility at theweld and adjacent zone. The pipe is passed through a series of cold sizing rolls toprogressively reduce the diameter to accurate size. This operation also increases strengthand improves surface pipe is then cut to specified length by a flying cut-off machine. After the straighteningoperation, ends of the pipe are cropped, then squared or bevelled depending on endfinish requirements.
