Quality assurance measures

 

1, technology and process:

My company's steel production and inspection process is in accordance with the requirements of API 5L and GB/T9711.1, and according to the standard gas pipeline at a higher level of technology transformation, from the tube and the two aspects of inspection equipment are capable of producing high quality of delivery pipe. In each batch of steel production, we have assessed according to the standard requirements for process of strict test, according to the evaluation results, to determine the technical parameters of steel tube production through optimization, to ensure the production of quality products. Then according to the process of decomposition to the production, inspection of each post, the post process parameters and operation method, so as to guide production. In the process of steel production, we perform the process discipline is strict supervision and inspection, to discover problems and take corrective and preventive measures, and assessment according to the system of quality assessment, to ensure strict enforcement of discipline, to ensure product quality.

2, inspection to ensure:

Our company established a full-time inspection agency, responsible for the raw materials into the factory to the product in the whole process of quality inspection. Steel pipe produced by our company have been examined 100% weld in the examination, 100%X ray inspection (pipe end there is no blind area); 100% water pressure test (hydraulic test was used to seal, pipe end blind area is reduced to the minimum 100%); visual inspection (including inside and outside the weld and base material surface). Our laboratory is equipped with advanced testing equipment, such as imported esparkle direct-reading spectrometer, digital tensile testing machine for mechanical properties testing, accurate chemical analysis of product; on-line automatic ultrasonic testing device and X ray industrial flaw detection device, can be non-destructive testing for 100% to the product, the hydraulic pressure test instrument can ensure automatic discipline pressure test and pressure of each pipe, in accordance with the provisions of the pressure of time. The product and the inspection process is responsible engineers responsible for and guidance, inspection personnel are all professional and technical training, non-destructive personnel holding NDT certificates. From the personnel to the equipment, can ensure the products according to the standard through strict quality inspection, the factory to ensure that the quality of products meet the standard requirements.

3, to ensure the quality system:

Our company actively the implementation of total quality management, according to the GB/T19001-ISO9001 and the American Petroleum Institute API Q1 standard established a quality system, person in charge until each production workers are exposed in the quality assurance system from general manager to each department. The company quality manual, strictly control the management responsibility, quality system, procurement, process control, inspection and test for more than 20 process, and made clear, so that each quality activities are in accordance with the provisions of the program, each job according to the standard of work. In quality management and inspection mainly adopt the principle of combining prevention, attach importance to and take preventive measures to avoid problems, not ignored in response to the event of problems timely, correct. The company planned arrangements at all levels of staff training, staff quality activities each, according to the education, training and appraisal of the situation, according to the release of the qualifications, certificates, and issued a certificate. Our company has passed GB/T19001-ISO9001 quality inspection, tracking control of a steel tube with a summons, make inspection record of the entire production process has good traceability.
