1. Scope
1.1 This specification 2 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 diameter and average 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 of0.148 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. For small diameter and light wall tube (converter sizes), see Appendix X2. 1.4 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. 1.5 The following safety hazards caveat pertains only to the test method portion, Section 12, of this specification. This standard does not purport to address all ofthe safety concerns, ifany, associated with its use. It is the responsibility ofthe user ofthis standard to become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limi- tations prior to use. 1.6 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
4. Ordering Information
4.1 It is the responsibility of the purchaser to specify all requirements that are necessary for the safe and satisfactory performance of material ordered under this specification. Examples of such 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 and Appendix X2. 4.1.2.1 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: 4.1.5.1 Cold Bending or Coiling. 4.1.5.2 Packing. 4.1.5.3 Rolling or Expanding into Tube Sheets. 4.1.5.4 Welding or Brazing—Process to be employed. 4.1.5.5 Hydrostatic Test or Nondestructive Electric Test— Specify type of test (6.5). 4.1.5.6 Pressure Requirements—If other than required by 6.5. 4.1.5.7 Ends—Plain ends cut and deburred will be fur- nished. 4.1.6 Supplementary Requirements—State nature and de- tails. 4.1.7 Certification—State if 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 of material at place of manufacture, the purchase order must so state indicating which tests or inspec- tions are to be witnessed (Section 13). 4.1.10 Small-Diameter and Light-Wall Tube (Converter Sizes)—See Appendix X2.
6. Mechanical Properties and Other Requirements
6.1 Mechanical Properties—The material shall conform 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 offinished 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. 6.4 Grain Size—A transverse sample representing full-wall thickness of annealed alloys UNS N08120, UNS N08810 and UNS N08811 shall conform to an average grain size ofASTM No. 5 or coarser.
