1. Scope
1.1 This specification contains various requirements that, with the exception of Sections 5 and 10, are mandatory requirements to the following ASTM nickel and nickel alloy, seamless pipe and tube specifications:1.2 One or more of the test requirements of Section 5 apply only if specifically stated in the product specification or in the purchase order. 1.3 In case of conflict between a requirement of the product specification and a requirement of this general specification, only the requirement of the product specification needs to be satisfied. 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 requirements portion, Section 5, 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.
3. Terminology
3.1 Definitions: 3.1.1 average diameter, n—the average ofthe maximum and minimum outside diameters, as determined at any one cross section of the pipe or tube. 3.1.2 nominal wall, n—a specified wall thickness with a plus or minus tolerance from the specified thickness. 3.1.3 seamless pipe, n—a round hollow produced with a continuous periphery in all stages of manufacture, and pro- duced to the particular dimensions commercially known as pipe sizes (NPS). 3.1.4 seamless tube, n—a tube produced with a continuous periphery in all stages of the operation. 3.1.5 thin wall tube, n—tube with specified wall thickness 3 % or less of the specified outside diameter.
5. Test Requirements
5.1 Flare Test—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.N OTE 1—Testing at a pressure greater than 1000 psi may be performed upon agreement between purchaser and manufacturer provided that the allowable fiber stress is not exceeded. 5.2.2 If any pipe or tube shows leaks during hydrostatic testing, it shall be rejected. 5.3 Nondestructive Electric Test: 5.3.1 Eddy Current Testing—Testing shall be conducted in accordance with Practices E426 or E571. The eddy current examination reference in this specification has the capability of detecting significant discontinuities, especially of the short, abrupt type. Unless otherwise specified by the purchaser, the calibration standard shall contain, at the option of the manufacturer, any one of the following discontinuities to establish a minimum sensitivity level for rejection. Drill Hole—A hole not larger than 0.031 in. (0.79 mm) diameter shall be drilled radially and completely through the wall, care being taken to avoid distortion of the material while drilling. Transverse Tangential Notch—Using a round file or tool with a 1 ⁄ 4 in. (6 mm) diameter, a notch shall be filed or milled on the tube or pipe outside diameter tangential to the surface and transverse to the longitudinal axis of the material. Said notch shall have a depth not exceeding 12.5 % of the specified wall thickness ofthe material, or 0.004 in. (0.10 mm), whichever is greater.
