ASME SB163:2015 pdf free download – SPECIFICATION FOR SEAMLESS NICKEL AND NICKEL ALLOY CONDENSER AND HEAT-EXCHANGER TUBES
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.
11.1.2 Whenever possible, all tubes shall be tested in full tubular size. When testing in full tubular size is not possible, longitudinal strip specimens, or the largest possible round specimen, shall be used. In the event of disagreement when full tubular testing is not possible, a longitudinal strip specimen with reduced gage length as contained in Test Methods E 8 shall be used.
11.1.3 In the case of stress-relieved tubes furnished with annealed ends, the tension test shall be made on the stress-relieved tubes prior to annealing the ends.
11.2 Hardness Test:
11.2.1 Stress-RelievedTubing with AnnealedEnds— The hardness test may be made on the inside of the tube near the end or on a specimen cut from the end, at the option of the manufacturer. The test shall be made on the inside of the specimen.
12. Test Methods
12.1 The chemical composition, mechanical, and other properties of the material as enumerated in this specifica- tion shall be determined, in case ofdisagreement, in accor- dance with the following methods:
13.1 Inspection ofthe material shall be made as agreed upon between the manufacturer and the purchaser as part of the purchase contract.
14. Rejection and Rehearing
14.1 Material not conforming to this specification or to authorized modifications will be subject to rejection.
14.2 Samples tested in accordance with this specifica- tion that represent rejected material shall be preserved for not less than three weeks from the date of the test report. In case of dissatisfaction with the results of the tests, the manufacturer may make claim for a rehearing within that time.
15. Certification
15.1 A manufacturer’s certificationshallbefurnishedto the purchaser stating that material has been manufactured, tested, and inspected in accordance with this specification, and that the test results on representative samples meet specification requirements. A report ofthe test results shall be furnished.
