(Specification)Standard Specification for U-Bend Seamless Copper and Copper Alloy Heat Exchanger and Condenser Tubes
Standard Specification for U-Bend Seamless Copper and Copper Alloy Heat Exchanger and Condenser Tubes
ABSTRACT
This specification establishes the requirements for condenser, evaporator, and heat exchanger U-bends that are manufactured from seamless copper and copper alloy tube. The material of manufacture shall be of such quality and purity that the finished product shall have the properties and characteristics specified. The material shall conform to the chemical composition requirements specified. Tensile test, expansion test, flattening test, mercurous nitrate test or ammonia vapor test, nondestructive examination, hydrostatic test, and pneumatic test shall be made to conform to the requirements specified.
SIGNIFICANCE AND USE
18.1 For purpose of determining compliance with the specified limits for requirements of the properties listed in the following table, an observed value or a calculated value shall be rounded as indicated in accordance with the rounding method of Practice E29.
Property
Rounded Unit for Observed or
Calculated Value
Chemical composition
nearest unit in the last
right-hand significant
digit used in expressing
the limiting value
Tensile strength
nearest ksi [nearest 5 MPa]
Elongation
nearest 1 %
Expansion
nearest 1 %
Grain size
nearest multiple of 0.005 mm
SCOPE
1.1 This specification2 establishes the requirements for condenser, evaporator, and heat exchanger U-bend tubes that are manufactured from seamless copper and copper alloy tube.
1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.3 This specification is applicable to product 2 in. [50 mm] or less, inclusive, in diameter.
1.4 The product shall be produced from one of the following coppers or copper alloys, as specified in the ordering information:
