Professional Stainless Steel Flange Manufacturer in China | Strict Quality & Factory Direct Supply

In the global piping and fluid control industry, high-precision and high-stability steel flanges are the core guarantee for the safe operation of industrial pipeline systems. As a professional Chinese manufacturer and exporter of stainless steel flanges and pipe fittings, we have been focusing on the R&D, production and processing of various standard and non-standard flange products for many years, serving engineering contractors, trading companies and industrial purchasers from all over the world.

Our factory covers a complete production and processing system, including raw material screening, CNC precision machining, surface polishing, pressure testing, dimensional inspection and finished product packaging. We mainly produce 304 and 316 stainless steel flanges, covering plate flat flanges, weld neck flanges, slip-on flanges, blind flanges, threaded flanges and socket weld flanges. All products are manufactured in strict accordance with ANSI, DIN, JIS, GB and other international mainstream standards, fully meeting the construction requirements of petrochemical, water treatment, natural gas, electric power, pharmaceutical and food processing projects.

Different from ordinary small processing factories, we implement a full-process quality control system. Each batch of raw materials is inspected for material composition before entering production. During processing, our technical staff strictly controls the flatness of the sealing surface, pipe diameter tolerance and welding groove accuracy. After production is completed, all finished products will undergo hydraulic pressure resistance test, air tightness test and dimensional re-inspection to eliminate defective products fundamentally.

Factory direct sales is our core advantage. Without any middlemen markup, we can provide customers with cost-effective flange products while ensuring stable product quality. At the same time, we support full customization services, including special size processing, non-standard shape customization, surface treatment customization and laser marking according to customer drawings and project requirements.

Adhering to the service concept of "quality first, customer foremost", we have established long-term stable cooperative relations with customers in Southeast Asia, Europe, America, the Middle East and other regions. We not only provide high-quality flange products, but also provide professional pre-sales selection guidance and after-sales technical support to solve various procurement and engineering matching problems for global customers.
