Quality control
The company continuously integrates quality control into all life cycles of WSA wet acid production projects by establishing a three-dimensional quality control system of «system certification + qualification assurance + whole process control»:
Authoritative system certification: The company has successively obtained ISO9001 quality management system, ISO14001 environmental management system and ISO45001 occupational health and safety management system certification, ensuring the standardization of product quality and project services at the management process level:
Key Certifications and Competencies:We hold a category B certificate for design in the chemical, petrochemical and pharmaceutical industries, a category one certificate for environmental projects, as well as licenses for A2 class pressure vessel fabrication, GC2 class pressure piping design and installation. All WSA sulfuric acid plants and associated equipment are designed, manufactured and installed in strict compliance with national safety regulations for specialty equipment and industry standards.
Full cycle of quality control:A quality control mechanism has been established for the entire cycle from raw material procurement to project acceptance - at the raw material stage, incoming inspection of key materials (titanium alloys, fiberglass, etc.) is performed to ensure that the material meets the requirements for corrosion resistance and strength; at the production stage, real-time monitoring of automated production line data is combined with manual patrolling to control the accuracy of machining at critical operations; at the assembly stage, special tests are performed to ensure that the material meets the requirements for corrosion resistance and strength; at the production stage, real-time monitoring of automated production line data is combined with manual patrolling to control the accuracy of machining at critical operations.
Due to the strict quality control system, the single acceptance rate of the company's WSA wet process acid recovery plants is 100%. The average uptime after putting the projects into operation exceeds 8000 hours. The product quality and engineering services have been widely recognized by customers at home and abroad. The company has already provided stable and reliable WSA wet acid technology solutions for hundreds of enterprises in Russia and abroad.
