Product Advantage
1. High Strength & Durability
Flanges are manufactured from high-quality materials such as carbon steel, stainless steel, and alloy steel, ensuring excellent mechanical strength and durability. With advanced heat treatment and precision machining, they can withstand high pressure, heavy loads, and long-term operation in harsh industrial environments.
2. Precise Machining Accuracy
Produced with advanced CNC machining and strict quality control, our flanges feature superior dimensional accuracy and smooth surface finishing. This guarantees reliable sealing performance and perfect compatibility with international standards, reducing the risk of leakage and ensuring system stability.
3. Corrosion & Pressure Resistance
Special surface treatments, such as anti-rust coatings or polishing, enhance resistance to corrosion, oxidation, and wear. Combined with strong pressure-bearing capability, our flanges are suitable for demanding industries such as oil & gas, petrochemical, and marine engineering.
4. Customization & Standards Compliance
All flanges can be customized according to client drawings, sizes, and technical standards (ANSI, DIN, JIS, EN, GB). This ensures seamless integration with global equipment and piping systems, meeting diverse project requirements with precision.

Product Uses
1. Oil & Gas Industry
Flanges are extensively used in oil and gas pipelines for connecting pipes, valves, and pumps. Their strong pressure resistance and reliable sealing ensure safe transportation of crude oil, natural gas, and refined products, even in high-pressure and offshore environments.
2. Machinery & Marine Engineering
In heavy machinery and marine engineering, flanges provide stable joints for hydraulic, cooling, and exhaust systems. Their robustness ensures reliable performance under vibration, seawater exposure, and other challenging conditions.
3. Petrochemical Plants
In petrochemical facilities, flanges are used to assemble complex piping systems that carry chemicals, acids, and gases. With corrosion-resistant materials and precise connections, they provide long-term stability, minimizing risks of leakage and system downtime.
Product Operate Guide
When installing flanges, first clean the sealing surfaces and align the pipes correctly. Place the gasket between the flanges, then insert and tighten the bolts gradually in a diagonal sequence to ensure uniform pressure. Avoid over-tightening to prevent damage. Regular inspection and maintenance will help extend service life and ensure safe operation.
