ASTM B730-08(R2018) pdf free download.Standard Speci fication for Welded Nickel (UNS N02200/UNS N02201 ) and Nickel Copper Alloy (UNS N04400) Tube
1. Scope
1.1 This specification covers nickel (UNS N02200), low- carbon nickel (UNS N02201), and nickel copper alloy (UNS N04400) in the form of welded and annealed or welded and stress-relieved tube intended for general corrosive service and for mechanical applications. 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 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 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 limitations prior to use. 1.4 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. Ordering Information
3.1 Orders for material under this specification shall include the following information:3.1.1 Alloy name or UNS number. 3.1.2 ASTM designation and year of issue. 3.1.3 Condition (Temper) (Table 1). 3.1.4 Dimensions: Outside diameter and nominal wall thickness. N OTE 1—Tube produced to outside diameter and minimum wall thickness may be furnished upon agreement between the manufacturer and the purchaser. Length (specific or random). 3.1.5 Quantity (feet or metres, or number of pieces). 3.1.6 Certification—State if certification is required. 3.1.7 Samples for Product (Check) Analysis—State whether samples for product (check) analysis should be furnished. 3.1.8 Purchaser Inspection—If the purchaser wishes to witness tests or inspection of material at the place of manufacture, the purchase order must so state indicating which tests or inspections are to be witnessed. 3.1.9 Nondestructive Tests—Specify either Test Category 1 or 2. If Test Category 1 is required, specify if either a hydrostatic, eddy-current or ultrasonic test is to apply. If Test Category 2 is required, specify which two tests are required. 3.1.10 Supplementary Requirements.
4. Materials and Manufacture
4.1 Tubes shall be made from flat-rolled material by an automatic welding process with no addition of filler metal. Subsequent to welding, and prior to heat treatment, the tubes shall be cold worked to assure that optimum corrosion resis- tance in the weld area and base metal will be developed during heat treatment. 4.2 Tubes shall be furnished with a scale-free finish. When bright annealing is used, descaling is not necessary.
