A Ovality - The permissible variations in this table apply to individual measurements,
including out-ofroundness (ovality) except for the folloing:

For pipe and tube having a nominal wall thickness of 3% or less of the nominal outside diameter, the mean outside
diameter shall conform to the permissible variations of this table and individual measurments (including ovality) shall
conform to the plus and minus values of the table, with the values increased by 0.5% of the nominal outside diameter.
For pipe and tube over 4½ in. (114) mm) in outside diameter with a nominal wall thickness greater than 3% of the nominal
outside diameter, the mean outside diameter shall conform to the permissible variations of this table and individual
measurenents shall not exceed twice the permissible varations of the table.

B Eccentricity - The permissible variations in this table apply to individual measurements including eccentricity.

TABLE4 PERMISSIBLE VARIATIONS IN LENGTHA

2(50.8) and over	3/16(4.8)	0

A These permissible variations in length apply to pipe or tube in straight lengths.
They apply to cut lengths up to and including 24 ft (7.3 m).

For lengths over 24 ft an additional over-tolerance of 1/8 in. (3.2 mm) for each 10ft (3.0m) or fraction
there of shall be permissible up to a maximum additional over-tolerance of 1/2 in. (12.7mm).

Stress-Relieved:
All sizes	16 200 psi (110 MPa)	15 000 psi (105 MPa)

t = minimum wall thickness, in. (or mm), equal to the specified nominal wall minus the permissible minus wall tolerance,
or the specified minimum wall thickness, and,

D = outside diameter of the pipe or tube, in. (or mm).

Test	Rounded Unit for Observed or Calculated Value
Chemical composition and tolerances (when expressed in decimals)	nearest unit in the last right-hand place of figures of the specified limit. If two choices are possible, as when the digits dropped are exactly a 5 or a 5 followed only by zeros, choose the one ending in an even digit, with zero defined as an even digit.
Tensile strength, yield strength	nerest 1000 psi (6.9 MPa)
Elongation	nearest 1%

X1. PIPE SCHEDULES

X1.1 The schedules of pipe shown in Table X1.1 are regularly available. Other schedules may be furnished, and the manufacturer should be consulted. Table X1.1 is published for information only.

X2. CONDITIONS AND FINISHES NORMALLY SUPPLIED

X2.1 Scope
X2.1.1 This Appendix lists the conditions and finishes in which pipe and tube (other than converter sizes) are normally supplied.
These are subject to change, and the manufacturer should be confulted for the latest information avaible.

X2.2.1 Annealed - Soft, with a dull matte finish.
X2.2.2 Stress-Relieved - Themally treated below the annealing temperature to relieve the major portion of the internal stresses,
with a thin, to mediumdark surface.

X2.3 Low-Carbon Nickel (UNS N02201)
X2.3.1 Annealed - Similar to X2.2.1
X2.3.2 Stress-Relieved - Similar to X2.2.2
