Plate Flanges — Cost-Effective & Reliable Piping Connections

Plate Flanges (also known as Flat Flanges) are designed to provide a strong, leak-proof connection between pipes, valves, pumps, and other equipment in a pipeline system. Manufactured from a flat steel plate, these flanges are welded directly to the end of the pipe, making them an economical and efficient choice for low-pressure applications across various industries.

Standards & Pressure Ratings

Plate flanges are produced according to international standards to ensure compatibility with a wide range of piping systems:

• ASME B16.5 — Class 150, 300 and higher upon request
• DIN / EN 1092-1 — PN6, PN10, PN16, PN25, PN40
• Available in Raised Face (RF) or Flat Face (FF) types depending on application

Key Features

• Simple & Economical Design — Manufactured from steel plates for cost-effective piping solutions.
• Easy Welding & Installation — Ideal for butt-weld or fillet-weld applications, ensuring quick setup.
• Standardized Dimensions — Matches international drilling patterns for seamless system integration.
• Good Structural Integrity — Provides a reliable sealing surface in low- to medium-pressure systems.
• Wide Material Range — Available in carbon steel, stainless steel, or special alloys to meet different operational needs.

Typical Dimensions

• Size Range: ½” to 24” (DN15–DN600) and above
• Pressure Ratings: ASME Class 150 / DIN PN6–PN40
• Facing Options: RF, FF
