Standard Specification for Nickel-Iron-Chromium Alloy Seamless Pipe and Tube

ABSTRACT
This specification covers the standard requirements for nickel-iron-chromium alloy which include UNS N08120, UNS N08800, UNS N08801, UNS N08810, UNS N08811, UNS N08890, and UNS N06811 in the form of cold-worked and hot-finished annealed seamless pipe and tube. The materials shall be heat treated at certain annealing temperatures and shall conform to the chemical composition limits for nickel, chromium, iron, manganese, carbon, copper, silicon, sulfur, aluminum, titanium, columbium, molybdenum, niobium, tantalum, phosphorus, tungsten, cobalt, nitrogen, and boron. Planimetric method of measurement and tension test shall be conducted in full tubular size, longitudinal strip, or round specimens in the direction of fabrication to determine the grain size and mechanical properties, respectively. These materials shall conform to the specified grain size, yield strength, tensile strength, and elongation requirements. Each pipe or tube shall be subjected to hydrostatic or nondestructive eddy-current tests to determine the allowable fiber stress and to detect significant discontinuities such as drilled hole and transverse tangential notch. The cold-drawn material shall be commercially straight, uniform in quality and temper, smooth, and free of bends, kinks, and other injurious imperfections.
SCOPE
1.1 This specification2 covers UNS N08120, UNS N08800, UNS N08801, UNS N08810, UNS N08811, UNS N08890, and UNS N06811 in the form of cold-worked and hot-finished annealed seamless pipe and tube. Alloys UNS N08800 and UNS N06811 are normally employed in service temperatures up to and including 1100°F (593°C). Alloys UNS N08120, UNS N08810, UNS N08811, and UNS N08890 are normally employed in service temperatures above 1100°F (593°C) where resistance to creep and rupture is required, and they are annealed to develop controlled grain size for optimum properties in this temperature range.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 The following safety hazards caveat pertains only to the test method portion, Section 7, of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer, to establish appropriate safety and health practices, and determine the applicability of regulatory limitations.

2) Annealed Pipe and Tube Over 4 ⁄2 in. (114.3 mm) in Nominal Outside Diameter—For annealed pipe and tubing over 4 ⁄2 in. (114.3 mm) in nominal outside diameter
with a nominal wall thickness greater than 3 % of the nominal outside diameter, the mean outside diameter or mean inside diameter shall conform to the permissible
variations of this table, and individual measurements shall not exceed twice the permissible variations of this table.
B
For pipe and tube, in all tempers, with an inside diameter of less than ⁄2 in. (12.70 mm) which cannot be successfully drawn over a mandrel, the inside diameter shall
be governed by the outside diameter and the wall thickness variations.
C
For pipe and tube in all tempers with an inside diameter less than 50 % of the outside diameter, which cannot be successfully drawn over a mandrel, the inside diameter
may vary over or under by an amount equal to 10 % of the nominal wall thickness and the wall thickness may vary ±15 %.
D
Eccentricity—The variation in wall thickness in any one cross section of any one cold-finished pipe or tube shall not exceed ±10 % of the actual (measured) average
wall of that section (defined as the average of the thickest and the thinnest wall in that section).
E
For tube 5 in. (127.0 mm) and under in outside diameter the tolerance on the outside diameter applies for individual measurements and includes ovality. For tubes over
5 in. (127.0 mm) in outside diameter the mean outside diameter shall conform to the permissible variations of this table and individual measurements shall not exceed twice
the permissible variations of this table.

A
The permissible variations in this table apply to individual measurements, including out-of-roundness (ovality), except for the following conditions.
1) Thin-Wall Pipe and Tube—For thin-wall pipe and tube having a nominal wall thickness of 3 % or less of the nominal outside diameter, in all conditions (temper), the
mean outside diameter or mean inside diameter shall conform to the permissible variations of this table, and individual measurements (including ovality) shall conform to
the plus and minus values of this table, with the values increased by 0.5 % of the nominal outside diameter.
1 1
2) Annealed Pipe and Tube Over 4 ⁄2 in. (114.3 mm) in Nominal Outside Diameter—For annealed pipe and tubing over 4 ⁄2 in. (114.3 mm) in nominal outside diameter
with a nominal wall thickness greater than 3 % of the nominal outside diameter, the mean outside diameter or mean inside diameter shall conform to the permissible
variations of this table, and individual measurements shall not exceed twice the permissible variations of this table.
B
For pipe and tube, in all tempers, with an inside diameter of less than ⁄2 in. (12.70 mm) which cannot be successfully drawn over a mandrel, the inside diameter shall
be governed by the outside diameter and the wall thickness variations.
C
For pipe and tube in all tempers with an inside diameter less than 50 % of the outside diameter, which cannot be successfully drawn over a mandrel, the inside diameter
may vary over or under by an amount equal to 10 % of the nominal wall thickness and the wall thickness may vary ±15 %.
D
Eccentricity—The variation in wall thickness in any one cross section of any one cold-finished pipe or tube shall not exceed ±10 % of the actual (measured) average
wall of that section (defined as the average of the thickest and the thinnest wall in that section).
E
For tube 5 in. (127.0 mm) and under in outside diameter the tolerance on the outside diameter applies for individual measurements and includes ovality. For tubes over
5 in. (127.0 mm) in outside diameter the mean outside diameter shall conform to the permissible variations of this table and individual measurements shall not exceed twice
the permissible variations of this table.
F
The diameter tolerances for tube with machined outside and inside diameters shall be +0.031 in. (0.787 mm), −0 for the outside diameter and +0, − 0.062 in. (1.57 mm)
for the inside diameter.
G
If tube is specified as minimum wall, the tolerance shall be +28.5 %, −0.
H
The wall thickness tolerance includes eccentricity tolerance up to ±12.5 %.
