As a professional manufacturer of SAE flanges and hydraulic pipe fittings, Yancheng Xinfujiete Machinery Co., Ltd. focuses on technological innovation and quality optimization in the hydraulic pipeline connection industry. Recently, the company’s independently developed new quick disassembly structure of SAE flange has been officially granted a national utility model patent (Patent No.: CN224283839U). Applied for in May 2025 and authorized in May 2026 by the National Intellectual Property Administration, this patent represents a major technological breakthrough in upgrading quick-disassembly SAE flange products and optimizing hydraulic connection performance.
Traditional SAE flanges adopt a 4-hole bolt fixing structure, which has prominent industry drawbacks. The complicated bolt disassembly and assembly process consumes plenty of time and increases maintenance costs. Bolts are prone to loosening and seal failure under long-term high pressure and vibration, resulting in poor equipment stability. In addition, operation in narrow spaces is difficult and causes prolonged equipment downtime.
To solve these pain points, Xinfujiete has developed an innovative 2-hole quick-disassembly SAE flange structure. It consists of upper and lower flange plates and gaskets, with fixing connecting columns and nuts for locking. The rotatable studs and fixing plates at the bottom realize multi-direction reinforcement, while the dual-sealing design of gaskets and end-face O-rings effectively prevents leakage and loosening.
The patented structure increases disassembly and assembly efficiency by over 60% and improves vibration and pressure resistance by 40%. It supports single-person operation in narrow spaces and is widely applicable to construction machinery, ships, hydraulic systems, energy and other fields. It greatly reduces material and labor costs, lowers equipment failure rates and cuts the full-life-cycle cost of equipment.
