The global market for SAE J518 standard hydraulic flanges achieved stable and robust growth in the first half of 2026, with the overall market volume registering a year-on-year increase of 7%–9%. As the core connecting component of high-pressure hydraulic systems, SAE flanges are widely applied in construction machinery, oil & gas, mining equipment, and industrial hydraulic facilities. Among all downstream sectors, construction machinery dominated the market as the largest end-user, accounting for 42% of the total consumption volume, followed by the oil & gas and mining industries.

In terms of regional performance, Southeast Asia emerged as the fastest-growing market with a 13% year-on-year growth rate, primarily fueled by booming local infrastructure construction and the strong export momentum of Chinese construction machinery. The North American market maintained steady growth of 8%, supported by rebounding regional energy investment and equipment renewal demands. The European market saw moderate growth at 4%, with overall demand remaining stable amid slow manufacturing recovery across the region.

From the product structure perspective, Code 62 (6000PSI) high-pressure SAE flanges outperformed Code 61 (3000PSI) standard-pressure products in market demand growth, reflecting the global industry’s upgrading trend toward high-load and high-pressure hydraulic systems. In addition, stainless steel and alloy steel flanges have gained increasing market traction, as they perfectly meet the stringent durability and corrosion resistance requirements of harsh working conditions in offshore, mining and chemical scenarios.

Looking ahead to the second half of 2026, sustained global infrastructure development and continuous energy capital expenditure will provide solid support for the steady expansion of the SAE flange market. Benefiting from complete industrial chain advantages, reliable product quality, flexible delivery cycles and customized service capabilities, Chinese SAE flange manufacturers are poised to further expand their global market share and strengthen their competitiveness in the international hydraulic fluid connection industry.
