【国外标准】 Standard Specification for General Requirements for Nickel and Nickel Alloys Seamless Pipe and Tube

This general specification contains the mandatory requirements to the ASTM standards listed herein for seamless pipes and tubes made from nickel and nickel alloys. In case of conflict, the requirements listed in the particular product specification takes precedence over those listed here.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:Title of Specification ASTMDesignation2Nickel Seamless Pipe and Tube B161Seamless Nickel and Nickel Alloy, Condenser and Heat Exchanger Tubes B163Nickel-Copper Alloy (UNS N04400) Seamless Pipe and Tube B165Nickel-Chromium-Aluminum Alloys (UNS N06699), Nickel-Chromium-Iron Alloys (UNS N06600, N06601, N06603, N06690, N06693, N06025, N06045, and N06696), Nickel-Chromium-Cobalt-Molybdenum Alloy (UNS N06617), Nickel-Iron-Chromium-Tungsten Alloy (UNS N06674), and Nickel-Chromium-Molybdenum-Copper Alloy (UNS N06235) Seamless Pipe and Tube B167Nickel-Iron-Chromium Alloy Seamless Pipe and Tube B407Nickel-Iron-Chromium-Molybdenum-Copper Alloy (UNS N08825, N08221, and N06845) Seamless Pipe and Tube B423Nickel-Chromium-Molybdenum-Columbium Alloys (UNS N06625 and N06852) and Nickel-Chromium-Molybdenum-Silicon Alloy (UNS N06219) Pipe and Tube B444Nickel-Iron-Chromium-Silicon Alloys (UNS N08330 and UNS N08332) Seamless Pipe B535Copper-Beryllium Alloy (UNS Nos.

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 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.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
