    Abstract

    This specification covers seamless pipe and tube of nickel and nickel-cobalt alloys. These alloys are classified into different grades according to chemical composition. Mechanical properties of the material like tensile strength, yield strength, and elongation shall be measured. Tension, hydrostatic, and nondestructive electric tests shall be done on each pipe or tube. The mass or weight of each pipe shall be calculated and the chemical composition of each pipe shall be determined.
