To further enhance the theoretical knowledge and practical skills of frontline employees, and to strengthen quality control awareness, the company organized a specialized pipe straightening training yesterday. The training was co‑delivered by the workshop manager and technical experts, and was attended by operators of relevant processes and quality management personnel. The training systematically focused on the straightening process for the company's main products – stainless steel welded pipes, stainless steel seamless pipes, heat exchanger tubes, aerospace tubes, and bright annealing tubes – aiming to consolidate quality foundations starting from this critical step.
During the training, the instructors explained the working principle of the straightening machine in relation to the company's actual production equipment, detailing the equipment's structural composition, transmission methods, and functions of key components. This helped participants understand the straightening process from a theoretical perspective, laying a solid foundation for precise operation. The instructors particularly pointed out that stainless steel seamless pipes and bright annealing tubes have especially high straightening accuracy requirements – even slight deviations in equipment parameters could affect the straightness and surface quality of the tubes. Therefore, operators must have a thorough grasp of equipment performance, knowing not only "how" but also "why."
In the section on operational precautions, the instructors emphasized standardized operating procedures and safety rules. During straightening, it is strictly forbidden to touch the straightening rolls or moving tubes by hand, to prevent surface scratches and indentations – a requirement that is especially critical for high‑surface‑quality products like aerospace tubes and bright annealing tubes. In addition, operators must wear required protective gear as specified, ensuring both production safety and product safety.
Quality control was a key focus of the training. The instructors pointed out that the straightening process directly affects the final quality of the product, and every adjustment of process parameters must be handled with the utmost care. The training defined post‑straightening quality inspection standards, including straightness deviation control, outer diameter dimensional accuracy, and tube surface quality requirements. Specific inspection criteria were refined for stainless steel welded pipes and heat exchanger tubes, taking into account their different specifications and characteristics. Participants also engaged in in‑depth discussions on straightening operations and quality issues encountered in daily production, sharing practical problems related to stainless steel seamless pipes and aerospace tubes during the straightening process, and jointly exploring improvement measures, resulting in multiple actionable optimization suggestions.
This training combined theory with practice, effectively enhancing participants' professional skills and quality awareness. The company will take this training as an opportunity to continue promoting job skill improvement, vigorously advocate craftsmanship spirit, and strive for excellence in the manufacturing of its full range of special tubes – stainless steel welded pipes, stainless steel seamless pipes, heat exchanger tubes, aerospace tubes, and bright annealing tubes – thereby consolidating the talent foundation for high‑quality enterprise development.
