Oleo Tecnica 90° Socket-Weld Flanges

Description

Oleo Tecnica 90° Socket-Weld Flanges represent a precision-engineered mechanical solution developed specifically for integration into hydraulic circuits requiring highly reliable angled connections. These components are manufactured using high-quality materials, including S355 carbon steel and AISI 316L stainless steel, ensuring high structural strength and compatibility with demanding industrial environments.

Ordering designations allow the product to be configured according to specific installation requirements. The base series (AFS…90S and AFX…90S) identify the flange only. To simplify installation, complete kits are available: the “SM” suffix (AFS…90SM, AFX…90SM) indicates a flange supplied complete with metric screws, spring washers and sealing O-ring. The “SU” suffix (AFS…90SU, AFX…90SU) instead indicates a configuration with UNC screws. It is important to note that UNC screw sets are available exclusively in carbon steel.

Series 3000 and Series 6000: Pressure Specifications and Sizes

The range is divided into two main performance categories, designed to meet different load conditions. Series 3000 covers sizes from 1/2″ up to 2″1/2, handling maximum recommended working pressures that vary according to size: from 345 Kg/cm² for the most compact dimensions (up to 1″), progressively decreasing to 276 Kg/cm², 207 Kg/cm² and finally 172 Kg/cm² for the largest 2″1/2 size.

Series 6000 is engineered for heavy-duty applications. It covers sizes from 1/2″ to 2″, offering significantly higher maximum working pressures: starting from 414 Kg/cm² for sizes from 1/2″ to 1″, then decreasing to 375 Kg/cm², 320 Kg/cm² and 250 Kg/cm² as the nominal diameter increases.

Installation Guidelines and Technical Notes

Correct installation of Oleo Tecnica 90° Socket-Weld Flanges requires careful attention to system specifications. The manufacturer specifies that the maximum recommended working pressure stated in the technical tables is based exclusively on the structural limits of the flange itself. The actual maximum working pressure of the complete system will be determined by the wall thickness and steel quality of the pipe used for welding.

During ordering or maintenance, attention must also be paid to certain construction exceptions. For example, for specific special models (as indicated for certain larger sizes), the component is machined directly from bar stock, and in these cases the fastening hardware is not supplied by the manufacturer. O-ring seals vary according to flange size, ranging from type 4075 for 1/2″ sizes up to type 4275 for 2″1/2 versions, always ensuring reliable hydraulic sealing of the 90° connection.
