Standard Specification for Seamless Nickel and Nickel Alloy Condenser and Heat-Exchanger Tubes
Abstract
This specification covers seamless tubes of nickel and nickel alloy for use in condenser and heat-exchanger service. This covers outside diameter and average wall, or outside diameter and minimum wall tube. Tube shall be furnished in the alloys and conditions defined by this specification. The material shall conform to the composition limits of nickel, copper, molybdenum, iron, manganese, carbon, silicon, chromium, aluminium, titanium, phosphorus, cerium, zirconium, yttrium, born, cobalt, columblum, tungsten, and nitrogen specified. Tensile strength, yield strength, elongation, and Rockwell hardness of the material shall conform to the required mechanical properties set by this specification. Test methods such as chemical analysis, tension, rounding procedure, Rockwell hardness, grain size and hardness conversion shall be performed.
Scope
1.1 This specification2 covers seamless tubes of nickel and nickel alloys, as shown in Table 1, for use in condenser and heat-exchanger service.
