Description
The Oleo Tecnica CETOP Flange Assembly with Butt-Weld Stub and Metric Screw Set is a key component for creating safe and stable connections in industrial hydraulic systems. This preassembled kit provides engineers and technicians with all the elements required for proper installation, ensuring maximum hydraulic sealing in compliance with industry specifications. The use of high-quality materials and precision machining ensures high resistance to mechanical stress and pressure peaks.
Assembly Composition and Construction Materials
Each ordering designation of the Oleo Tecnica CETOP Flange Assembly with Butt-Weld Stub and Metric Screw Set includes a complete kit ready for installation. Specifically, the package includes:
- A solid CETOP flange manufactured from S355 steel.
- A stub with O-ring seat specifically designed for butt welding, available in A105 steel or AISI316L stainless steel.
- Four metric socket head cap screws (TCE).
- Four Grower-type spring lock washers.
- One O-ring sized to ensure fluid leak tightness.
It is important to note that, for applications in particularly aggressive or corrosive environments, the entire CETOP flange can be supplied in AISI316L stainless steel (or equivalent) upon request, thereby ensuring a significantly longer operational service life.
Pressure Specifications and Series Variants
The assembly is engineered and divided into two primary categories according to pressure resistance performance:
- Series 250: Designed for a maximum recommended working pressure of 250 Bar. This series covers all operating sizes from 3/8 inch up to 4 inches, with weights ranging from a minimum of 0.20 Kg for the smallest size up to 11.30 Kg for the heavy-duty 4-inch version.
- Series 400: Intended for systems requiring even higher performance, supporting a maximum recommended working pressure of 400 Bar. Available sizes mirror the previous series (from 3/8″ to 4″), but the reinforced structure increases the weight of the largest flange up to 13.00 Kg.
The technical documentation clearly specifies that the maximum recommended working pressure is based exclusively on flange performance. Consequently, the maximum working pressure of the entire system is determined by two factors external to the component: the thickness of the pipe used and the type of material (steel grade) of the pipe itself.
