Shanxi Jianing Forging can process 304, 304L, 316, 316L stainless steel forgings, with a complete range of real-world cases of stainless steel flanges, shafts, and ring forgings, offering excellent corrosion resistance and suitable for chemical and seawater corrosion protection conditions.
A seawater desalination plant in Baoji, Shaanxi, selected stainless steel forgings among key equipment for the connection between high-pressure pumps and pipelines. The factory has long faced the corrosive environment of seawater with high chloride ions, placing strict requirements on the corrosion resistance and sealing of metal components. Jianing Forging provides the plant with customized stainless steel forgings, effectively supporting its daily freshwater production capacity of tens of thousands of tons.
The seawater desalination process involves high pressure, high salinity, and high humidity conditions. Traditional castings or ordinary stainless steel parts experience pitting, crevice corrosion, and stress corrosion cracking during use, with an average replacement cycle of less than 6 months. At the same time, insufficient machining accuracy of components leads to seal failure, increasing downtime maintenance costs. Customers urgently need a forging solution with stable overall performance and long service life to reduce operating costs throughout the entire lifecycle.
To address these pain points, Jianing Forging uses duplex stainless steel materials and refines grains through multi-directional forging processes, resulting in dense forgings and improved corrosion resistance. Combined with fine turning and non-destructive testing, dimensional tolerances are kept within ±0.05mm, and the sealing surface roughness reaches Ra0.4μm. The product has operated continuously and stably for over 18 months without any corrosion or leakage issues, helping customers reduce maintenance frequency by more than 70%.
