Although the advanced technology and equipment are a prerequisite for the product quality, the operators’ ideological standards and skill levels must be raised in order to get high-quality products. Every operator shall set up the ideas of “quality first” and shall have high sense of responsibility for quality. Therefore, we often provide on-the-job training to make the operators have a better understanding of theoretical knowledge of production, operating skills, quality control, technological changes and technical standards, thus ensuring that the production can be organized in accordance with the specified requirements and that the product quality can be improved in a steady way.
Quality Inspection and Control
Raw material Inspection includes:
visual inspection, dimensional check, physical & chemical experiments;
Internal inspection and external inspection includes:
dimensional check of steel pipe, visual inspection of welds and the
inspection of other technical requirements;
Non-Destructive Examination includes:
on-line ultrasonic inspection, manual ultrasonic inspection, real-time image formation X-ray test, and X-ray test;
Final inspection:
includes final check of the steel pipe, the review of all the results of the previous inspections.
We evaluate and record all inspections in accordance with the testing results and product specifications to ensure the quality of finished products. All records are maintained in accordance with the specified requirements to look up them in the future.
