5.1 Flare Test—The flare test shall consist of flaring a test specimen with an expanding tool having an included angle of 60°
until the specified outside diameter has been increased by 30 %. The flared specimen shall not exhibit cracking through the wall.
5.2 Hydrostatic Test—Each pipe or tube shall be tested by the manufacturer to an internal hydrostatic pressure of 1000 psi (6.9
MPa) provided that the fiber stress, calculated from the following equation, does not exceed the allowable fiber stress for the
material:

B829 – 04a (2009)
where:
P = hydrostatic test pressure, psi (MPa),
S = allowable fiber stress, for material in the condition (temper) furnished as specified in the product specification (S is
2 1
calculated as the lower of ⁄3 of the specified minimum 0.2 % offset yield strength or ⁄4 of the specified minimum ultimate
strength for the material),
t = minimum wall thickness permitted, in. (mm), including minus tolerance, if any, and
D = nominal outside diameter of the pipe or tube, in. (mm).
5.2.1 The test pressure must be held for a minimum of 5 s.
NOTE 1—Testing at a pressure greater than 1000 psi may be performed upon agreement between purchaser and manufacturer provided that the
allowable fiber stress is not exceeded.
5.2.2 If any pipe or tube shows leaks during hydrostatic testing, it shall be rejected.
5.3 Nondestructive Electric Test:
5.3.1 Eddy Current Testing—Testing shall be conducted in accordance with Practices E 426 or E 571E426 or E571. The eddy
current examination reference in this specification has the capability of detecting significant discontinuities, especially of the short,
abrupt type.
5.3.1.1 Unlessotherwisespecifiedbythepurchaser,thecalibrationstandardshallcontain,attheoptionofthemanufacturer,any
one of the following discontinuities to establish a minimum sensitivity level for rejection.
5.3.1.2 Drill Hole—A hole not larger than 0.031 in. (0.79 mm) diameter shall be drilled radially and completely through the
wall, care being taken to avoid distortion of the material while drilling.
5.3.1.3 Transverse Tangential Notch—Using a round file or tool with a ⁄4 in. (6 mm) diameter, a notch shall be filed or milled
on the tube or pipe outside diameter tangential to the surface and transverse to the longitudinal axis of the material. Said notch
shall have a depth not exceeding 12.5 % of the specified wall thickness of the material, or 0.004 in. (0.10 mm), whichever is
greater.
5.3.2 Ultrasonic Testing—Testing shall be conducted in accordance with Practice E 213E213. The ultrasonic examination
referred to in this specification is intended to detect longitudinal discontinuities having a reflective area similar to or larger than
the calibration reference notches specified in 5.3.2.1. The examination may not detect circumferentially oriented imperfections or
short, deep defects.
5.3.2.1 For ultrasonic testing, longitudinal calibration notches shall be machined on the outside and inside diameter surfaces.
The depth of the notches shall not exceed 12.5 % of the specified wall thickness or 0.004 in. (0.10 mm), whichever is greater.
5.3.3 Calibration Frequency—The frequency of calibration checks shall be as follows:
5.3.3.1 At the beginning of each production run or lot.
5.3.3.2 At least every four hours during testing.
5.3.3.3 At the end of each production run or lot.
5.3.3.4 After any suspected equipment malfunction or work stoppage.
5.3.3.5 If, during any check, the equipment fails to detect the calibration defects, the instrument must be recalibrated and all
material tested since the last satisfactory check shall be retested.
5.3.4 Acceptance and Rejection—Material producing a signal equal to or greater than the calibration defect shall be subject to
rejection.
5.3.4.1 Test signals produced by imperfections that cannot be identified or produced by cracks or crack-like imperfections shall
result in rejection of the pipe or tube, subject to rework and retest.
5.3.4.2 Iftheimperfectionisjudgedasnotfitforuse,thetubeshallberejected,butmaybereconditionedandretestedproviding
the wall thickness requirements are met. To be accepted, retested material shall meet the original electric test requirements.
5.3.4.3 If the imperfection is explored to the extent that it can be identified, and the pipe or tube is determined to be fit for use,
the material may be accepted without further testing, providing the imperfection does not encroach on minimum wall thickness
requirements.
5.4 When specified by the purchaser, a nondestructive electric test, in accordance with Practices E 213E213, E 426E426, or E
571E571, may be used for seamless pipe or tube, instead of the hydrostatic test.
5.5 Tension Test—Tension testing shall be conducted in accordance with Test Methods E 8E 8E8/E8M.
5.5.1 The material shall conform to the tensile properties prescribed in the individual product specification.
5.6 Hardness Test—Hardness testing shall be conducted in accordance with Test Methods E 18E18.
5.7 Grain Size—The measurement of average grain size may be carried out by the planimetric method, the comparison method,
or the intercept method described in Test Methods E 112E112. In case of dispute, the “referee” method for determining average
grain size shall be the intercept method.
5.8 For purposes of determining compliance with the specified limits for requirements of the properties listed in the following
table, an observed value or a calculated value shall be rounded in accordance with the rounding method of Practice E 29E29:
Requirements Rounded Unit for Observed
or Calculated Value
B829 – 04a (2009)
Chemical composition and nearest unit in the last right-hand place
tolerances of figures of the specified limit
Tensile strength and yield strength nearest 1000 psi (7 MPa)
Elongation nearest 1 %
Grain size
0.0024 in. (0.060 mm) or larger nearest multiple of 0.0002 in. (0.005 mm)
Less than 0.0024 in. (0.060 mm) nearest multiple of 0.0001 in. (0.002 mm)
6. Dimensions and Permissible Variations
6.1 Dimensions of pipe are shown in Table 1.
6.1.1 Permissible variations in outside diameter and wall thickness are shown in Table 2, Table 3, and Table 4.
6.2 Length—When material is ordered as cut-to-length, the length shall conform to the permissible variations prescribed in
Table 5. When material is ordered to random lengths, the lengths and variations shall be agreed upon between the manufacturer
and purchaser.
6.3 Straightness—Material shall be reasonably straight and free of bends and kinks.
6.4 Ends—Ends shall be plain cut and deburred.
7. Workmanship, Finish,Finish and Appearance
7.1 The material shall be uniform in quality and temper, smooth, and free from imperfections that would render it unfit for use.
8. Sampling
8.1 Lot Definition:
8.1.1 A lot for chemical analysis shall consist of one heat.
8.1.2 A lot for all other testing shall consist of all material from the same heat, nominal size (excepting length), and condition
(temper). When final heat treatment is in a batch-type furnace, a lot shall include only those pipes or tubes of the same size and
the same heat that are heat-treated in the same furnace charge. When heat treatment is in a continuous furnace, a lot shall include
all pipes or tubes of the same size and heat, heat-treated in the same furnace at the same temperature, time at
