Weld Heat Treatment Process

Since the in-line heat treatment process of X42 ERW Steel Pipes has appeared since the 1960s, processes and technologies have been increasingly perfected to date. In general, the heating method is generally induction heating; in order to ensure the accuracy of the welding of the weld to the weld, the advanced units are mostly equipped with an automatic tracking system for photoelectric welds: in order to ensure the stability of the heating temperature, and with automatic temperature control In addition to the most commonly used weld seam normalizing and weld annealing processes, some manufacturers use a quenching and tempering heat treatment process for high-strength steel pipes to improve the weld toughness. Refinement improves the impact toughness of the SGP ERW Steel Pipe CS. In addition, there are normalizing and tempering, quenching and tempering, as well as the recent research and development of the deformation heat treatment process.
