As a pipeline of oil and natural gas, spiral pipe has its own characteristics: 1. The amount of use is large, because the specifications of SA573 Grade 65 bulb flat, spiral pipe used in a project are often diversified. During the forming process of the spiral pipe, the steel plate deforms evenly, the residual stress is small, and the surface does not occure scratches. 2. The spiral pipe is used in a complex environment, and the quality must be guaranteed, otherwise it will delay the follow-up project progress.

SA573 Grade 65 bulb flat annealing is to heat the steel to 30 ~ 50℃ above the critical temperature, keep it in the heat treatment furnace for a period of time, and then cool it down to room temperature with the furnace. The purpose of SA573 Grade 65 bulb flat annealing is to refine the grain of steel, eliminate internal stress and reduce hardness, improve cutting performance, increase toughness and plasticity, and facilitate welding and rolling processes. SA573 Grade 65 bulb flat annealing can be complete annealing, incomplete annealing, stress relief annealing, isothermal annealing and spheroidizing annealing.
