Abstract

This specification establishes the requirements for threadless, seamless, and deoxidized copper pipes in straight lengths, in all nominal or standard pipe sizes, for piping systems that are assembled with brazed-joint pipe fittings. The pipe shall be produced from coppers with either UNS No. C10300 or C12200. The materials for manufacture shall be cast billets, bars, or tubes of such purity and soundness as to be suitable for processing by hot extrusion or piercing, and subsequent cold working to produce a uniform wrought structure in the finished product. Products shall be produced in the H58 (drawn general purpose) temper. Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (outer and inner diameters, wall thickness, cross-sectional area, theoretical weight, mass, length, and roundness or squareness), mechanical (tensile strength and Rockwell hardness), and chemical composition requirements. Products shall also meet performance requirements under microscopical examination, electromagnetic (eddy-current) test, hydrostatic test, and pneumatic test.

Scope

1.1 This specification establishes the requirements for copper-nickel alloy castings with nominal compositions shown in Table 1. These are as follows:2

Copper Alloy UNS No.2

Previous Designation

 

C96200

Alloy A

C96400

Alloy B

1.2 Castings of these alloys are used primarily for corrosion-resistance applications such as in construction and for pressure vessels, particularly in marine pumps, valves, and fittings.

1.3 These alloys are considered weldable, but they may be ordered with a weld test to ensure weldability. When extensive welding is to be performed on the casting, weldability tests should be specified in the ordering information (5.2.6) to ensure proper welding characteristics.

1.4 Units—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 hazard statement applies only to Section 8, Weldability Test, 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 establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
