What is Flange Resurfacing?

Flange resurfacing, also known as flange facing, is a critical step in the process of ensuring a proper seal with a gasket or other sealing material. This process involves the removal of corrosion, scratches, build-up, and many other imperfections from the face of the flange.

Why is Flange Resurfacing Important?

Flange resurfacing is essential because it ensures a proper seal between flanged connections, preventing leaks in critical systems. A properly prepared flange face allows gaskets to fit securely, which is crucial in maintaining system integrity and safety, particularly in high-pressure or hazardous environments.

By restoring damaged or worn flanges, flange facing not only improves sealing performance but also helps to extend the lifespan of equipment, reduce maintenance costs, and prevent costly downtime or potential accidents. Ultimately, it’s a cost-effective solution for ensuring leak-free, efficient operations in various industries.

How Flange Resurfacing Works

Flange resurfacing typically begins with thoroughly inspecting the flange to assess the type and extent of damage. This includes checking for pitting, warping, corrosion, or deep scratches. Once assessed, the area is carefully cleaned to remove any dirt, grease, or corrosion that may interfere with the resurfacing process.

Using a specialized portable flange resurfacing tool, technicians are able to remove a thin layer of material from the flange surface. The goal is to recreate the original serrated finish pattern, depending on the specifications of the flange type. Technicians must follow industry standards (like ASME or ANSI) to meet the required surface finish and dimensional tolerances.

Once resurfacing is complete, the flange is inspected again to confirm that the surface finish and flatness are within specification. This step ensures the flange is ready for safe and reliable sealing when reassembled for operation.
