Oleo Tecnica Flat Socket-Weld Counter Flanges

Description

Oleo Tecnica Flat Socket-Weld Counter Flanges represent an essential engineering solution for the hydraulic components sector and for Fluid Contamination Control. Included within the specific Series 3000 of the LTH catalogue, these components are designed to enable extremely precise coupling in systems requiring the socket-weld technique. The construction architecture and machining tolerances of the flat flange are specifically designed to optimise structural load distribution and withstand the continuous mechanical stresses typical of complex industrial hydraulic circuits.

Working Pressure and Operating Parameters

A critical technical parameter for system sizing and safety is the working pressure. All models belonging to this specific range of Series 3000 counter flanges are rigorously calibrated to operate safely with a maximum recommended working pressure of 40 Kg/cm². This specification applies to the entire product range, regardless of the nominal size selected for installation, thus ensuring a constant and uniform performance standard throughout the circuit in which the components are integrated.

Construction Materials: S355 Steel and AISI 316L

The correct selection of materials is essential for the durability and reliability of the hydraulic component. The ordering designations highlight two distinct metallurgical options for the manufacture of the flange body. The standard configuration uses S355 steel, a structural steel with a high yield strength that is ideal for the vast majority of conventional hydraulic applications (identified by the code GFC). For operating environments characterised by high corrosiveness or for industrial sectors requiring strict chemical standards, the counter flanges are also available in AISI 316L stainless steel (easily identifiable by the presence of the letter “X” in the designation code, for example GFCX).

Threads and Fastening Options

To ensure full compatibility with different international mechanical assembly standards, Series 3000 counter flanges are available with different drilling configurations. Fastening is securely achieved through four dedicated perimeter holes. The designer or installer can select models equipped with metric threaded fastening holes (ranging from M8 for smaller sizes up to M16 for larger diameters) or choose versions fitted with standard UNC threaded holes (from 5/16″ up to 5/8″). Versions with UNC standard threads are immediately identifiable by the suffix “SU” in the final ordering code (for example GFC…SU for S355 steel variants or GFCX…SU for the corresponding AISI 316L stainless steel versions).

Dimensions, Sizes and Weights

The available dimensional range is highly scalable and has been structured to meet every potential hydraulic piping requirement. Nominal sizes (Size) start from the most compact 1/2″ format and extend up to the maximum size of 5″. As the size progressively increases, all the main geometric dimensions required for installation (identified in the technical drawing by the letters A, B, C, D, E, F, H, I) and the thread diameter (M) vary proportionally. By way of example, the most compact 1/2″ model (GFC080S) has an extremely low weight of just 0.12 Kg, while the larger 5″ model (GFC118S), engineered to handle considerable fluid flow rates, reaches a total weight of 3.00 Kg. The overall thickness (H) and all related centre distances (C and E) are rigorously calibrated to ensure perfect, leak-free mechanical coupling.
