Construction Features and Materials<\/h3>\n

Oleo Tecnica Butt-Weld Flanges for Metric Pipe with Cylindrical Bore<\/strong> are essential components for creating rigid and secure connections in high-pressure hydraulic systems. Designed to ensure leak-tight sealing and optimum mechanical strength, these flanges are manufactured from high-quality steel, ensuring durability and reliability even under demanding operating conditions. The design features a cylindrical bore optimised for precise coupling with metric-diameter pipes, simplifying butt-welding operations and minimising pressure losses within the hydraulic circuit.<\/p>\n

Operating Principle and Applications<\/h3>\n

The operating principle is based on a full-penetration welded connection between the metric pipe and the flange body. This configuration allows mechanical stresses and hydraulic pressures to be distributed evenly, preventing critical weak points. Oleo Tecnica Butt-Weld Flanges for Metric Pipe with Cylindrical Bore are ideal for applications in heavy industrial sectors and mobile automation, including hydraulic presses, earthmoving machinery, marine systems and agricultural machinery, where a permanent, secure connection resistant to severe vibrations and extreme pressure peaks is required.<\/p>\n

Technical Specifications and Compatibility<\/h3>\n

These flanges are designed to meet a wide range of dimensional and flow requirements. Precision machining of the cylindrical bore ensures perfect alignment with standard metric pipes. Maximum working pressures vary according to flange size and series, while maintaining high safety factors under all conditions to prevent structural failure. They are fully compatible with standard hydraulic fluids, mineral oils and lubricants typically used in the hydraulic sector.<\/p>\n
