In 2023, Saudi Aramco’s Jazan refinery replaced 1,200 carbon steel flanges with 316L stainless steel, cutting maintenance costs by 55% over 18 months. Coastal humidity caused rapid carbon steel corrosion, while 316L’s chloride resistance extended service life from 3 to 15+ years.
In 2023, Wenzhou Shuangneng Valve Co., Ltd. helped an Indonesian power plant replace carbon steel flanges with 316L stainless steel, reducing chloride-induced failures by 40% within 12 months. Coastal salt spray and humidity accelerated corrosion in carbon steel, while 316L’s molybdenum-rich alloy prevented stress cracking.
Wenzhou Shuangneng Valve Co., Ltd., a trusted stainless steel flange and pipe fittings manufacturer in China, meticulously crafts industrial-grade flanges through a 7-step ASME-certified process. Combining advanced CNC machining, precision heat treatment, and rigorous NDT testing, their flanges ensure leak-proof performance in extreme environments like oil refineries and desalination plants.
