Technology Advantages

Wujin Stainless has led and participated to formulate and revise more than 20 national and industrial standards, and own 67 valid patents, including 23 invention patents and 44 utility model patents. These patents cover the product manufacturing and inspection process, demonstrating the company independent intellectual property.

Aiming at the domestic blank of stainless steel seamless pipe system for supercritical thermal power boiler, Wujin has carried out self-dependent innovation. It has formed core technologies and process products with independent intellectual property. It has passed appraisement of sci-tech achievement of China Machinery Industry Federation, the National Technical Committee of Standardization of Boiler and Pressure vessel, and China Electrical Engineering Society, which has reached the advanced level of similar products overseas, replaced imports. Other technical advantages include: cold rolling technique of large diameter thick wall seamless pipe with one time large deformation, which made the product has uniform grain size through the large deformation cold rolling to refining the internal grain.
