Materials and Manufacture
Manufacture—At the manufacturer’s option, pipe may
be either hot finished or cold finished, with a suitable finishing
treatment, where necessary.
Heat Treatment:
All pipe shall be furnished in the heat-treated condition unless the order specifically states that no final heat
treatment shall be applied. When the order is furnished without
final heat treatment, each pipe shall be stenciled “HT-O.”
As an alternate to final heat treatment in a continuous
furnace or batch-type furnace, immediately following hot
forming while the temperature of the pipes is not less than the
specified minimum solution treatment temperature, pipes may
be individually quenched in water or rapidly cooled by other
means.
Grades TP304, TP304N, TP304LN, TP316, TP316N,
TP316LN, TP321, TP347, TP348, 16-8-2H, S 31725, and
S 31726 —Unless otherwise stated in the order, heat treatment
shall consist of heating to a minimum temperature of 1900 °F
[1040 °C] and quenching in water or rapidly cooling by other
means.
The purchaser may specify controlled structural or
special service characteristics which shall be used as a guide
for the most suitable heat treatment. If the final heat treatment
is at a temperature under 1900 °F [1040 °C], each pipe shall be
stenciled with the final heat treatment temperature in degrees
Fahrenheit or Celsius after the suffix “HT.”
Grades TP304H, TP316H, TP321H, TP347H,
TP348H, and 16-8-2H—If cold working is involved in pro
cessing, the minimum solution-treating temperature for Grades
TP321H, TP347H, and TP348H shall be 2000 °F [1100 °C], for
Grades TP304H and TP316H, 1900 °F [1040 °C], and for
Grade 16-8-2H, 1800 °F [980 °C]. If the material is hot-rolled,
the minimum solution-treating temperatures for Grades
TP321H, TP347H, and TP348H shall be 1925 °F [1050 °C],
for Grades TP304H and TP316H, 1900 °F [1040 °C], and for
Grade 16-8-2H, 1800 °F [980 °C].
 Grade S34565—Heat treatment shall consist of heating to a temperature in the range of 2050 °F [1120 °C]
minimum and 2140 °F [1170 °C] maximum, and quenching in
water or rapidly cooling by other means.
A solution annealing temperature above 1950 °F [1065
°C] may impair the resistance to intergranular corrosion after
subsequent exposure to sensitizing conditions in TP321,
TP321H, TP347, TP347H, TP348, and TP348H. When specified by the purchaser, a lower temperature stabilization or resolution anneal shall be used subsequent to the initial high
temperature solution anneal (see Supplementary Requirement
S9).
The grain size of grades 304H, 316H, 321H, 347H, and
348H as determined in accordance with Test Methods E 112,
shall be No. 7 or coarser.

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 of Welded and Seamless Stainless Steel Pipe and Nominal Weights of Steel Pipe
Stainless steel pipe ASME B36.19M
SCOPE
This Standard covers the standardization of dimensions of welded and seamless wrought stainless 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. Pipes 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 wall thicknesses for NPS 14 through 22, inclusive (DN 350–550, inclusive), of Schedule 10S; NPS 12 (DN
300) of Schedule 40S; and NPS 10 and 12 (DN 250 and 300) of Schedule 80S are not the same as those of ASME
B36.10M. The suffix “S” in the schedule number is used to differentiate B36.19M pipe from B36.10M pipe. ASME
B36.10M includes other pipe thicknesses that are also commercially available with stainless steel material.
SIZE
The size of all pipe in Table 1 is identified by the nominal pipe size. The manufacture of pipe NPS 1⁄8 (DN 6) through 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 thicknesses — 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.
5 WEIGHTS
The nominal weights1 of steel pipe are calculated values and are tabulated in Table 1.
(a) 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 used for OD only in mathematical
equations or formulas)
W
pe p nominal plain end weight, rounded to the
nearest 0.01 lb/ft
t p specified wall thickness, rounded to the nearest 0.001 in.
(b) 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 1.0 mm for outside diameters
larger than 16 in. (the symbol D is 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 5S and 10S wall thicknesses do not permit
threading in accordance with ANSI/ASME B1.20.1.
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 code, whichever governs the construction. A thickness shall be selected from
the schedules of nominal thickness contained in Table
1 to suit the value computed to fulfill the conditions for
which the pipe is desired.

Dimensions and Weights of Welded and Seamless Wrought Steel Pipe
Welded and Seamless Wrought Steel Pipe ASME 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.
