Anotácia textu normy ASTM B366/B366M-23 :
This specification covers wrought welding fittings, including threaded fittings, for pressure piping, factory-made from nickel and nickel alloys. The term welding applies to butt-welding or socket-welding parts such as elbows, bends, caps, tees, reducers, lap-joint, and stub ends. This specification does not apply to cast welding fittings. Grades of nickel and nickel alloys included in this specification are designated with a prefix, WP or CR, based on dimensional and rating standards. WP grades have class designations (Class S, Class W, Class WX, and Class WU) to indicate whether seamless or welded construction is utilized and to indicate the nondestructive test method and extent of nondestructive examination (such as radiography and/or ultrasonic test). The material for wrought welding fittings may consist of forgings, rods, bars, plates, sheets, and seamless or welded pipe that conform to all the specified requirements. Forging or shaping operations may be performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, or fusion welding, or by a combination of two or more of these operations. Chemical and product analyses shall conform to the chemical composition prescribed. Requirements for tensile properties, heat treatment, tension test, and dimensions are detailed. Hydrostatic testing of wrought fittings is not required by this specification.

1.1?This specification covers wrought welding fittings for pressure piping, factory-made from nickel and nickel alloys. Threaded fittings as covered in ASME B16.11 are also covered by this specification. The term welding applies to butt-welding or socket-welding parts such as 45? and 90? elbows, 180? bends, caps, tees, reducers, lap-joint stub ends, and other types, as covered by ASME B16.9, ASME B16.11, MSS SP-43, MSS SP-95, and MSS SP-97. 1.1.1?Several grades of nickel and nickel alloys are included in this specification. Grades are designated with a prefix, WP or CR, based on the applicable ASME or MSS dimensional and rating standards. 1.1.2?Class WP fittings are those manufactured to the requirements of ASME B16.9, B16.11. 1.1.3?For each of the WP nickel and nickel alloy grades, several classes of fittings are covered to indicate whether seamless or welded construction was utilized. Class designations are also utilized to indicate the nondestructive test method and extent of nondestructive examination (NDE). Table 1 is general summary of the fitting classes applicable to all WP grades of nickel and nickel alloys covered by this specification. There are no classes for the CR grades. Specific requirements are covered elsewhere. 1.2?This specification does not apply to cast welding fittings. 1.3?Optional supplementary requirements are provided for fittings where a greater degree of examination is desired. These supplementary requirements call for additional tests. When desired, one or more of these may be specified in the order. 1.4?The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.5?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. |
