Project Description

C71500 (CuNi30Mn1Fe) Copper Nickel 70/30 Tubes -ASTM B111

ASTM B111 C71500 Copper Nickel Tube is the best resistance of any of the copper alloys to impingement attack and to corrosion from most acids and waters. It is being used in severe corrosive conditions in which service lives longer than those of other copper alloys are desired.

C68700 ASTM B 111/B 111M establishes the requirements for seamless tube and ferrule stock of copper and various copper alloys up to 3 Vs in. [80 mm] inclusive, in diameter, for use in surface condensers, evaporators, and heat exchangers.

Expansion Test

  • C71500 (CuNi30Mn1Fe) Copper Nickel Tube specimens selected for test shall withstand the expansion shown in standard when expanded in accordance with Test Method B 153. The expanded tube shall show no cracking or rupture visible to the unaided eye.
  • Hard-drawn tubes not end annealed are not subject to this test. When tubes are specified end annealed, this test is required and shall be performed on the annealed ends of the sampled tubes.
  • Tubes for ferrule stock are not subject to the expansion test.

Flattening Test

  • Test Method: Each test specimen shall be flattened in a press at three (3) places along the length, each new place to be rotated on its axis approximately one third turn from the last flattened area. Each flattened area shall be at least 2 in. in length. A flattened test-specimen shall allow a micrometer caliper set at three (3) times the wall thickness to pass freely over the flattened area. The flattened areas of the test specimen shall be inspected for surface defects.
  • During inspection, the flattened areas of the test- specimen shall be free of defects, but blemishes of a nature that do not interfere with the intended application are acceptable.
  • Tubes for ferrule stock are not subject to flattening test.

Residual Stress Test

  • A residual stress test is required to be performed only for Copper Alloy UNS Nos. C70600, C71500, C71640.
  • Unless otherwise specified, the producer shall have the option of testing the product to either the mercurous nitrate test, Test Method B 154, or the ammonia vapor test, Test Method B 858, as prescribed below.

Nondestructive Testing

Eddy-Current Test—Each C71500 (CuNi30Mn1Fe) Copper Nickel tube shall be passed through an eddy-current testing unit adjusted to provide information on the suitability of the tube for the intended application. Testing shall follow the procedures of Practice E 243.

Hydrostatic Test

Each Copper Nickel tube shall stand, without showing evidence of leakage, an internal hydrostatic pressure sufficient to subject the material to a fiber stress of 7000 psi [48 MPa] as determined by the following equation for thin hollow cylinders under tension. The tube need not be tested at a hydrostatic pressure of over 1000 psi [7.0 MPa] unless so specified.

P 5 2St/~D 2 0.8t

where:

P = hydrostatic pressure, psi [MPa];

t = thickness of tube wall, in. [mm];

D = outside diameter of the tube, in. [mm]; and S = allowable stress of the material, psi [MPa].

Materials and Manufacture:

  • When specified in the purchase order or contract, the purchaser shall be furnished certification that samples representing each lot have been either tested or inspected as directed in this specification and requirements have been met.
  • When identified in the ordering information that product is purchased for ASME Boiler and Pressure Vessel Code applications, certification to this specification is mandatory.

Note:

  • Mill test certificates will be issued EN10204 3.1 or 3.2
  • All tubes shall be supplied as per applicable ASTM B111 /B 111M Specification.
