. Scope 1.1 This specification covers seamless tubes of nickel and nickel alloys, as shown in Table 1, for use in condenser and heat-exchanger service. 1.2 This specification covers outside diameterand aver- age wall, or outside diameter and minimum wall tube. 1.2.1 The sizes covered by this specification are 3 in. (76.2 mm) and under in outside diameter with minimum wall thicknesses of 0.148 in. (3.76 mm) and under, and with average wall thicknesses of 0.165 in. (4.19 mm) and under. 1.3 Tube shall be furnished in the alloys and conditions as shown in Table 2. 1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 The following safety hazards caveat pertains only to the test method portion, Section 12, ofthis specification. This standard does not purport to address all ofthe safety concerns, ifany, associated with its use. It is the responsi- bility ofthe user ofthis standard to become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet for this product/material as provided by the manufacturer, to establish appropriate safety andhealth practices, anddetermine the applicability ofregulatory limitations prior to use. 2.

Terminology 3.1 Definitions: 3.1.1 average diameter, n—average ofthe maximum and minimum outside diameters, as determined at any one cross section of the tube. 3.1.2 tube, n—hollow product of round or any other cross section having a continuous periphery. 4. Ordering Information 4.1 It is the responsibility ofthe purchaser to specify all requirements thatare necessary forthe safe andsatisfactory performance of material ordered under this specification. Examples ofsuch requirements include, but are not limited to, the following: 4.1.1 Alloy (Table 1). 4.1.2 Condition (Temper) Table 3 and Appendix X1. If annealed ends for stress relieved tubing are desired, state length of end to be annealed and whether or not one end or both ends are to be annealed. 4.1.3 Finish. 4.1.4 Dimensions—Outside diameter, minimum or average wall thickness (in inches, not gage number), and length. 4.1.5 Fabrication Operations: Cold Bending or Coiling. Packing. Rolling or Expanding into Tube Sheets. Welding or Brazing—Process to be employed. Hydrostatic Test or Nondestructive Elec- tric Test—Specify type of test (6.5). Pressure Requirements—If other than required by 6.5. Ends—Plain ends cut and deburred will be furnished. 4.1.6 Supplementary Requirements—State nature and details. 4.1.7 Certification—Certification is required (Sec- tion 15). 4.1.8 Samples for Product (Check) Analysis— Whether samples for product (check) analysis shall be furnished. 4.1.9 Purchaser Inspection—If purchaser wishes to witness tests or inspection ofmaterial at place ofmanufac- ture, the purchase order must so state indicating which tests or inspections are to be witnessed (Section 13). 4.1.10 DELETED 5. Chemical Composition 5.1 The material shall conform to the composition lim- its specified in Table 1. 5.2 If a product (check) analysis is performed by the purchaser, thematerialshall conformto the product(check) analysis per Specification B 880. 6. Mechanical Properties and Other Requirements 6.1 Mechanical Properties—The material shall con- form to the mechanical properties specified in Table 3. 6.2 Hardness—When annealed ends are specified for tubing in the stress-relieved condition (see Table 3), the hardness of the ends after annealing shall not exceed the values specified in Table 3. 6.3 Flare—A flare test shall be made on one end of 1% of the number of finished tube lengths from each lot. For less than 100 tubes in a lot, a flare test shall be made on one end of one tube length in the lot. In the case of stress relieved tubing with annealed ends, the test shall be made prior to, or subsequent to, annealing of the ends at the option of the manufacturer. 6.3.1 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.
