We are proud to announce the official launch of our Custom Non-Standard Special-Shaped SAE Adapter Flange Service. Tailored for special hydraulic valve block renovation scenarios where standard flanges fail to fit, we provide one-stop solutions covering drawing analysis, material selection, precision machining and finished product testing. This service effectively solves the pipeline docking bottlenecks in hydraulic system upgrading and old equipment reconstruction, delivering reliable high-pressure fluid connection solutions for engineering machinery, marine offshore equipment, tunnel boring machines, die-casting equipment, wind power hydraulic stations and other industrial fields.

In hydraulic equipment technical renovation and old valve block upgrade projects, most on-site working conditions face common challenges including special valve block mounting hole positions, limited installation space and offset multi-oil circuit docking. Standard SAE flanges with fixed specifications often result in mismatched hole spacing, installation interference and unreasonable pipeline routing. In this case, customers have to reprocess or even replace the original valve block, leading to higher renovation costs, longer project cycles and potential risks to the overall pressure resistance and operational safety of hydraulic equipment.

To address these industry-wide pain points, our newly launched non-standard special-shaped SAE adapter flange service adopts standard SAE connection benchmarks while supporting fully customized structural optimization. According to customers’ 2D/3D drawings, physical samples or on-site measured data, we can produce special-shaped SAE adapter flanges with irregular outlines, non-standard hole spacing, multi-pass transition, eccentric transition and reducing conversion structures. The products comply with Code 62, 3000PSI/6000PSI high-pressure standards, with optional materials including carbon steel, 304/316 stainless steel and duplex stainless steel, adapting to harsh working conditions of high pressure, corrosion resistance and heavy load.

As a transitional connecting fitting, our special-shaped SAE adapter flange perfectly compensates for the size difference between the original valve block interface and the new pipeline. There is no need to modify or remake the valve block body, which greatly reduces secondary processing costs and shortens the overall equipment renovation cycle.

The sealing surface and oil port dimensions strictly follow SAE industrial standards. Only the external outline and installation structure are customized, ensuring stable sealing performance under high pressure and eliminating hydraulic oil leakage risks. We can provide EN10204 3.1 material certification to guarantee product quality and industrial compliance.

We support customized production of various complex structures, including eccentric flanges, unequal-spacing multi-hole flanges, special-shaped avoidance notches, integrated reducing joints and multi-oil circuit integrated adapter flanges. We accommodate small-batch prototype trial production and large-scale mass production with controllable delivery cycles.

All finished products undergo full-dimensional inspection and high-pressure pressure resistance testing. The customized SAE adapter flanges are widely applicable to hydraulic system renovation projects for TBM tunnel boring machines, mining machinery, die-casting & extrusion machines, marine offshore equipment, new energy wind power hydraulic stations and other high-end hydraulic equipment.

Customer provides drawings / physical samples / on-site dimension data → Technical team evaluates feasibility, confirms material selection and customized scheme → CNC precision machining → Non-destructive testing & dimensional inspection → Surface treatment → Factory delivery & after-sales technical support. Our professional technical team provides whole-process docking service to assist customers in verifying installation interference, sealing matching and pressure resistance parameters.

The launch of our non-standard special-shaped SAE adapter flange customization service fills the market gap of standard SAE flanges in special hydraulic valve block retrofit scenarios. We continue to focus on the R&D and customization of high-pressure hydraulic fluid connectors, providing supporting products including SAE split flanges, hydraulic joints, three-way pipe fittings and various non-standard hydraulic flanges. We welcome global hydraulic engineering contractors, equipment renovation enterprises and hydraulic system supporting manufacturers to consult for professional technical solutions and quotations.
