Quantity
Jiangsu SAE Flange products are precision-engineered hydraulic flanges manufactured in strict accordance with SAE J518 and ISO 6162 Part 2 standards. Available in sizes from 1/2 inch to 4 inches, these butt weld flanges are crafted from premium SS304 stainless steel, offering exceptional corrosion resistance and mechanical strength. With a maximum working pressure of 6,000 psi, they are built for extreme operating conditions. The butt weld connection ensures weld integrity equal to the base material, delivering a reliable, leak-free seal that outperforms threaded or slip-on alternatives.
Design Standards and Technical Compliance
The Jiangsu SAE Flange series fully complies with both SAE J518 and ISO 6162 Part 2, the globally recognized benchmarks for hydraulic flange connections. These standards guarantee dimensional interchangeability, rigorous material certification, and verified pressure ratings. For instance, a 1-inch SAE butt weld flange features a bolt circle diameter of 2.75 inches (69.85 mm) with four bolt holes, ensuring seamless compatibility across manufacturers worldwide. Every flange undergoes factory pressure testing at 1.5 times the working pressure—up to 9,000 psi for 6,000 psi rated units—to verify sealing performance and structural integrity under real-world conditions.

Material and Performance Advantages
The use of SS304 stainless steel provides superior resistance to oxidation, chemical attack, and thermal stress, making these flanges ideal for corrosive or high-temperature environments. The butt weld design eliminates potential leak paths and reduces stress concentration points, significantly enhancing fatigue life compared to socket weld or threaded connections. This combination of material quality and connection technology ensures long-term reliability, minimizing system downtime and maintenance costs.

Application Scenarios
Jiangsu SAE Flanges are widely deployed in hydraulic power units, mobile equipment, industrial machinery, petrochemical processing, offshore platforms, and energy transmission systems. They are particularly valued in applications requiring high-cycle fatigue resistance, vibration tolerance, and absolute sealing integrity—such as injection molding machines, steel mill hydraulic circuits, and subsea control lines. Their standard compliance also makes them a preferred choice for OEMs exporting equipment to North American, European, and Asian markets.

Jiangsu’s Flange Manufacturing Industry
Jiangsu Province, particularly the Yangtze River Delta region, stands as a cornerstone of China’s flange and pipe fitting industry. With decades of manufacturing history, cities like Wuxi, Changzhou, and Nantong host hundreds of specialized foundries, forging plants, and CNC machining workshops. The local supply chain—from raw material sourcing (including domestic and imported stainless steel coils) to heat treatment, precision machining, and surface finishing—is remarkably integrated. Many Jiangsu-based factories hold ISO 9001, PED, and API certifications, and have accumulated extensive experience in exporting SAE J518 flanges to the U.S., Europe, and the Middle East. The region’s competitive advantages lie in cost-effective production, fast lead times (often 15–30 days for standard sizes), and flexible customization for non-standard patterns or special coatings. Ongoing investments in automated forging lines and digital inspection systems have further elevated product consistency, making Jiangsu a recognized hub for high-quality SAE hydraulic flanges worldwide.
