A threaded flange is a type of pipe flange with internal threads on its bore, allowing it to be screwed onto a pipe with corresponding external threads, eliminating the need for welding for connection.
In 2023, Wenzhou Shuangneng Stainless Steel Flange and Pipe Fitting Manufacturer in Zhejiang Wenzhou pioneered a high-demand project, crafting corrosion-resistant stainless steel flanges for offshore oil rigs. Faced with rising industry needs for durable marine components, the team employed advanced forging techniques and rigorous pressure testing, delivering 5,000 units within 8 weeks, ensuring compliance with international safety standards and reinforcing their leadership in precision manufacturing.
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.
