Butt-weld flanges are the preferred engineering solution for ensuring stable, leak-tight connections in hydraulic systems operating at high pressures and subject to strong mechanical vibrations. Designed for permanent structural integration with steel piping, these components ensure maximum flow continuity and high resistance to mechanical stress. Unlike threaded fittings, which may be vulnerable to cyclic loosening, welded technology eliminates the risk of leakage, making it essential in hydraulic presses, steel plants, earthmoving machinery and offshore applications.
The selection of the most suitable configuration depends on the system layout and the available installation space. For standard connection lines requiring direct, robust and linear fastening, Oleo Tecnica Butt-Weld Flanges for Metric Tube with Cylindrical Bore provide an extremely precise connection. To complete the flanged joint and ensure proper mechanical tightening of the hydraulic block, the corresponding Oleo Tecnica Butt-Weld Counterflanges for Metric Tube with Cylindrical Bore are required.
In layouts where space is limited or where the fluid flow needs to change direction without the addition of intermediate fittings, Oleo Tecnica 90° Butt-Weld Flanges provide an efficient solution, allowing sharp directional changes with minimal pressure losses. Finally, for more complex applications requiring parallel connections or the connection of supply and return lines positioned very close together, Oleo Tecnica Double Butt-Weld Flanges ensure maximum compactness, optimizing installation space and increasing the rigidity of the entire connection assembly.
