Description
Oleo Tecnica Socket-Weld Flanges for Metric Pipe are high-precision technical components designed for hydraulic professionals who require reliable, robust connections that fully comply with industrial fluid contamination control requirements. This type of fitting is specifically engineered to withstand demanding duty cycles and maintain the integrity of fluid power transmission in modern high-pressure circuits.
Series 3000: Working Specifications
Series 3000 offers a range of flanges suitable for hydraulic systems with medium- and high-pressure requirements. Depending on the selected size, the maximum recommended working pressure varies to ensure consistent structural safety. For 1/2″, 3/4″ and 1″ sizes, the flanges provide maximum resistance up to 345 Kg/cm2. As the nominal size increases to 1″1/4, the recommended pressure limit is 276 Kg/cm2, while for the 1″1/2 size the maximum permitted working pressure is 207 Kg/cm2.
Series 6000: Performance for Heavy-Duty Applications
For applications requiring significantly higher pressure tolerances, Series 6000 offers enhanced specifications for installation in highly stressed circuits. Models in this series, in 1/2″, 3/4″ and 1″ versions, operate with complete stability up to 414 Kg/cm2. For larger diameters, the 1″1/4 flange has a recommended operating limit of 276 Kg/cm2, while the 1″1/2 version is engineered to withstand operating peaks up to 320 Kg/cm2.
Material Composition and Supply Variants
From a materials perspective, the ordering designation makes it possible to identify the most suitable metal alloy for the operating environment. The flanges are manufactured in S355 carbon steel (AFS base code) or, alternatively, in AISI 316L stainless steel (AFX base code).
To simplify assembly, the components can be supplied in three different configurations:
- Flange only (identified by the SA suffix).
- Flange supplied complete with metric screws, spring washers and O-ring (SMA suffix).
- Flange supplied complete with UNC screws, spring washers and O-ring (SUA suffix).
During system design, it is essential to note that configurations equipped with UNC screws are available exclusively in carbon steel.
System Sizing Rules
A crucial technical aspect concerns the evaluation of assembly safety limits: the maximum recommended working pressure stated in the technical data sheets refers strictly to the sealing performance of the flange itself. The maximum working pressure of the complete system will instead be determined, and potentially limited, by the wall thickness and construction material of the metric steel pipe used in the connection.
