Improvement of quality through changes in the longitudinal and circumferential weld preparation instructions for pressure vessels and tanks.
By changing to outside corner welding, stable product production becomes possible!
We would like to introduce examples of our stainless steel tank and filter housing manufacturing. When designing stainless steel pressure vessels or tanks with a diameter of φ500 or less, if the specifications of the pressure vessel or tank allow, stable manufacturing can be achieved by instructing the bevel of the weld joint on the outside. By stabilizing the welding position and conditions, we can ensure consistent manufacturing of pressure vessels and tanks, which leads to stable product quality and reduced production lead times. [Key Points of the Case] - By understanding the processes involved in actual manufacturing and designing accordingly, high-quality products can be obtained. - Especially for small-diameter (up to φ500) stainless steel pressure vessels and tanks, where quality defects are more likely to occur, changing to outside bevel welding allows for stable product production. *For more details, please refer to the PDF document or feel free to contact us.
