End of pipe end
Plain Ends (PE)			The PE pipes will generally be used for the smaller diameters pipe systems and in combination with Slip On flanges and Socket Weld fittings and flanges.

Threaded Ends (TE)			The TE implementation speaks for itself, this performance will generally used for small diameters pipe systems, and the connections will be made with threaded flanges and threaded fittings.

Beveled Ends (BE)			The BE implementation is applied to all diameters of buttweld flanges or buttweld fittings, and will be directly welded (with a small gap 3-4 mm) to each other or to the pipe. Ends are mostly be beveled to angle 30° (+ 5° / -0°) with a root face of 1.6 mm (± 0.8 mm).


Grooved ends			(example Victaulic pipes): these are pipes that allow a quick connection, used for non-critical applications
Threaded and coupled ends			(T&C), generally used for gas distribution, Threaded connections are the most common pipe fittings used in oil and gas transportation systems. Due to external vibrations, cyclic loads, and pollution, the fitting parts may start getting loose, which could result in pipeline leaks and other environmental disasters. It is of great significance to develop a reliable technique that could provide…

Dimensions and Weights of Welded and Seamless Wrought Steel Pipe
Welded and Seamless Wrought Steel Pipe					ASME /ANSI B36.10M-2004
SCOPE This 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.					SIZE 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.









MATERIALS The dimensional standards for pipe described here are for products covered in ASTM specifications.					WALL THICKNESS The nominal wall thicknesses are given in Table 1.

WEIGHTS The nominal weights of steel pipe are calculated values and are tabulated in Table 1. The nominal plain end weight, in pounds per foot, is calculated using the following formula: W pe p 10.69(D − t)t where D p outside diameter to the nearest 0.001 in. (the symbol D is to be used for OD only in mathematical equations or formulas) W pe p nominal plain end mass, rounded to the nearest 0.01 lb/ft t p specified wall thickness, rounded to the nearest 0.001 in. The nominal plain end mass, in kilograms per meter, is calculated using the following formula: W pe p 0.0246615(D − t)t where D p outside diameter to the nearest 0.1 mm for outside diameters that are 16 in. (406.4 mm) and smaller and to the nearest 1.0 mm for outside diameters larger than 16 in. (406.4 mm) (the symbol D is to be used for OD only in mathematical equations or formulas) W pe p nominal plain end mass, rounded to the nearest 0.01 kg/m t p specified wall thickness, rounded to the nearest 0.01 mm					PERMISSIBLE VARIATIONS Variations in dimensions differ depending upon the method of manufacture employed in making the pipe to the various specifications available. Permissible variations for dimensions are indicated in each specification.




					PIPE THREADS Unless otherwise specified, the threads of threaded pipe shall conform to ANSI / ASME B1.20.1, Pipe Threads, General Purpose (Inch). Schedules 5 and 10 wall thicknesses do not permit threading in accordance with ANSI/ASME B1.20.1.





					WALL THICKNESS DESIGNATIONS The wall thickness designations Standard, ExtraStrong, and Double Extra-Strong have been commercially used designations for many years. As explained in the Foreword, the Schedule Numbers were subsequently added as a convenient designation for use in ordering pipe. Standard and Schedule 40 are identical for up to NPS 10 (DN 250), inclusive. All larger sizes of Standard have 3⁄8 in. (9.53 mm) wall thicknesses. Extra-Strong and Schedule 80 are identical for up to NPS 8 (DN 200), inclusive. All larger sizes of Extra-Strong have 1⁄2 in. (12.70 mm) wall thicknesses. Pipe of sizes and wall thicknesses other than those of Standard, Extra-Strong, and Double Extra-Strong, and Schedule Number were adopted from API Specification 5L. It was not considered practical to establish Schedule Numbers or new designations for them.















WALL THICKNESS SELECTION When the selection of wall thickness depends primarily upon capacity to resist internal pressure under given conditions, the designer shall compute the exact value of wall thickness suitable for conditions for which the pipe is required, as prescribed in detail in the ASME Boiler and Pressure Vessel Code, ASME B31 Code for Pressure Piping, or other similar codes, whichever governs the construction. A thickness shall be selected from Table 1 to suit the value computed to fulfill the conditions for which the pipe is desired.
