  • Q What is the definition of Heat Number and Test Number in Tubing Coupling?

    A In Tubing Coupling, Heat Number is that Metal produced during a single cycle of feeding and smelting. Test Number is that A limited quantity of products produced under the condition of consistent attributes to be inspected .
  • Q What is the importance of Heat Number and Test Number in Tubing Coupling?

    A In Tubing Coupling, Heat Number is used to control the traceability of the chemical composition of steel grades. Test Number is is used to control the traceability of the physical, chemical, and structural properties of steel grades (such as tensile properties, impact properties, metallographic properties, etc.)
