Grafton Pipe Fittings is a trusted manufacturer and global supplier of premium Reducing Flanges, designed to offer smooth and efficient pipe connections of different diameters. Our reducing flanges are highly demanded across various industrial sectors such as petrochemical, oil and gas, chemical processing, power generation, and marine applications. These flanges are manufactured in compliance with the highest international standards to ensure durability, dimensional accuracy, and leak-free connections in high-pressure environments.

Our Reducing Flanges are engineered from ASTM A105 material, a carbon steel forging material used for high-temperature service in pressure systems. The corresponding UNS number is K03504, and the universal standard designation includes ASME B16.5 and ANSI B16.5. These standards specify dimensions, tolerances, materials, and testing procedures to maintain quality and performance consistency. Each flange we manufacture undergoes rigorous quality checks, including hydrostatic testing, ultrasonic inspections, and PMI testing, before it reaches our clients.

The primary purpose of a reducing flange is to connect two pipes of different diameters without the need for separate reducers or other fittings. Grafton Pipe Fittings' ASTM A105 reducing flanges are ideal for space-constrained areas where the installation of a conventional reducer is not feasible. These flanges also offer enhanced flow efficiency and reduced turbulence, thereby improving the overall performance of your piping system. They are available in pressure classes ranging from 150 to 2500 and in different face types such as Raised Face (RF), Flat Face (FF), and Ring Type Joint (RTJ).

We provide custom sizes and finishes to accommodate specific client requirements. Whether you're working with a high-pressure steam system or an offshore oil rig, Grafton Pipe Fittings delivers reliable Reducing Flanges built to perform. Our manufacturing capabilities support global projects with on-time delivery, competitive pricing, and technical support.
