Description
Introduction to CETOP Flanges
Oleo Tecnica CETOP Flanges fall within the category of hydraulic components designed for fluid contamination control and high-pressure management. The rigorous design of these technical components focuses on providing the product in the “flange only” configuration, ensuring maximum dimensional precision for seamless integration into hydraulic systems and complex industrial circuits.
Working Pressures: Series 250 and Series 400
The reliability of the hydraulic system depends on selecting the correct component according to the maximum recommended working pressure. Oleo Tecnica CETOP Flanges are carefully classified into two distinct performance families:
- Series 250: Designed to withstand a maximum recommended working pressure of 250 Bar. This series covers the full range of sizes available in the catalogue, ensuring optimal sealing performance and complete structural stability in medium- and high-pressure circuits.
- Series 400: Developed for significantly more demanding applications, this version supports a maximum recommended working pressure of up to 400 Bar. Despite the considerable increase in pressure resistance, the component maintains the same connection dimensional standards for the corresponding sizes, facilitating system upgrade operations.
Construction Materials
The mechanical strength, structural integrity and durability of the component under severe operating loads are ensured by the rigorous selection of materials. Oleo Tecnica CETOP Flanges are manufactured and supplied in two different material versions:
- S355 Steel: Standard structural material selected to ensure excellent mechanical performance in conventional and heavy-duty hydraulic applications.
- AISI 316L Stainless Steel: A variant specified to ensure optimal performance under specific environmental or operating conditions. The ordering designation for stainless steel models follows the dedicated CETX…ST coding.
Dimensions, Overall Sizes and Available Sizes
The dimensional range of Oleo Tecnica CETOP Flanges is extremely broad in order to suit virtually any system configuration. The nominal sizes available for both pressure series include: 3/8″, 1/2″, 3/4″, 1″, 1″1/4, 1″1/2, 2″, 2″1/2, 3″, 3″1/2 and 4″.
The reference dimensions provided for correct installation include parameters A, B, C, D, H and L. These define the overall dimensions precisely. For example, for the 1″ size in Series 250 (model CET1ST250), dimension A is 45,3, dimension C is 38,5, and thickness L is 11. The overall weight (K) varies significantly depending on size and series, starting from a minimum of 0,13 Kg for the 3/8″ flange (Series 250) and reaching up to 5,70 Kg for the largest 4″ model in both pressure series.
Ordering Designation
For correct identification and supply of the “flange only” component, the ordering designation follows a precise and unambiguous coding system. Standard models are identified by the prefix “CET”, followed by the size, the code “ST”, and finally the numerical value of the pressure series (e.g. CET…ST…). As mentioned above, for specific versions manufactured from stainless steel, the coding follows the format “CETX…ST”. This unique classification eliminates the margin for error during procurement, ensuring exact technical correspondence with project requirements.
