Heating the steel pipe above the critical temperature, and cooled in the air.(pipe) Heat Treatment Of Steel -Tempering, Hardening, (steel) In the case of Hot Finished Pipe, no heat treatment is required. As during the manufacturing process, the pipe temperature remains in the range of heat treatment temperature till the final size and thickness are achieved. Whereas in the case of Cold Finished Pipe, heat treatment is required as per applicable ASTM standard. As the pipe is either cold drawn or temperature is not maintained in the hot finish range.

Heat Treatment- Annealing, Normalizing, Hardening The API Steel Pipe Normalizing Heat Treatment

Normalizing is a heat treatment process similar to annealing in which the Steel is heated to about 50 degree Celsius above the upper critical temperature followed by air cooling. This results in a softer state which will be lesser soft than that produced by annealing.(pipe) Heat-treating line pipe weld seams - The Fabricator(steel) Why Heat-Treat Weld Seams?2D Numerical AnalysisLine Layout and Seam TrackingSimulation VerificationDuring high-frequency welding, the outer and inner sides of the pipe wall experience the highest temperatures. This creates a heat-affected zone (HAZ) with a characteristic hour-glass shape. The heat also changes the tensile properties of the HAZ, reducing its toughness (its ability to absorb an impact without rupturing). Weld-seam heat treatment re-establishes the tensile properties of theHAZ, bringing them back to levels equal to those of the base material.
