Production Description
Steel Flanges are used to connect pipes, valves, fittings, or other equipment.
The EN 1092 standard is a European standard that specifies the requirements for circular flanges made of steel, stainless steel, or aluminum alloy, used in various industrial applications.
It specifies requirements for dimensions, materials, pressure ratings (PN), flange types (like slip-on, welding neck, or blind flanges), joint face finishes, and marking for various applications, covering a wide range of sizes from DN 10 to DN 4000.
Flange Types: It specifies different types of steel flanges, such as:
Type 01: Plate (slip-on) flanges for welding.
Type 05: Blank (blind) flanges to close off pipe ends.
Type 11: Welding neck flanges, known for high-strength connections.
Dimensions & Tolerances: The standard provides precise specifications for flange dimensions and tolerances to ensure proper fit and performance.
Marking: Flanges must be marked according to the standard, often including the nominal size (DN).
Applications: EN 1092-1 flanges are widely used in industries such as oil and gas, mining, and general manufacturing for connecting pipes, pumps, and vessels.
