Dimensions	- Outer Diameter: Available in various sizes, e.g., 1/2", 3/4", 1", etc. - Wall Thickness: Ranges from 0.035" to 0.125" depending on the application and pipe size
Mechanical Properties	- Tensile Strength: Minimum 30,000 psi (annealed condition) - Yield Strength: Minimum 10,000 psi (annealed condition) - Elongation: Minimum 35% in 2 inches (annealed condition)
Manufacturing Process	- The tubes are produced by extrusion, drawing, and annealing processes to ensure high quality and dimensional accuracy.
Surface Finish	- The surface of the copper tubes is smooth and clean, free from defects such as scratches, pits, and oxides.
Applications	- Widely used in refrigeration and air - conditioning systems, plumbing, electrical wiring, and heat exchangers.
Standards	- Complies with ASTM B88 (Standard Specification for Seamless Copper Water Tube), and other relevant international standards.

 

Expansion Test

• 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. C23000, C28000, C44300, C44400, C44500, C60800, C61300, C61400, and C68700.
• 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 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 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.
