FI60E Flange Facing Machine Restores Flange Integrity at Pressure Vessel Manufacturer

At the beginning of 2025, our team delivered a state-of-the-art FI60E flange facing machine to a customer based in Hangzhou, China. The customer specializes in pressure vessel manufacturing and was facing a critical challenge with flange welding distortion. This distortion had caused severe deviations in the flatness of the sealing faces, making it impossible to meet the required sealing standards for their pressure vessels. The customer urgently needed a solution to repair these flanges and restore their integrity.

The Challenge: Flange Distortion and Sealing Face Repair

The customer's pressure vessel production involved large, heavy-duty flanges, and during the welding process, certain flanges suffered from thermal distortion, resulting in misalignment and an unacceptable flatness of the sealing faces. These distortions posed a significant risk to the integrity and safety of the pressure vessels, and without the right equipment to correct the issue, production could be delayed.

After discussing the customer's needs with their technical team, our engineers identified that the flanges in question typically had sealing face diameters of 1.5 meters or smaller. Based on this, we recommended our FI60E flange facing machine, which is designed to repair sealing faces ranging from 320mm to 1500mm in diameter. The FI60E is particularly well-suited for their operation, as it can efficiently restore the sealing face flatness of smaller flanges—something the customer was experiencing on a regular basis.

Solution: Tailored Service with a Maintenance Contract

The customer required an immediate and cost-effective solution for routine flange repair. Given that they only occasionally required repairs for flanges with diameters larger than 1.5 meters, we proposed a framework agreement that would cover all their flange repair needs for an entire year. This included a guaranteed service response time of just three days for any large-diameter flange repairs. With this contract in place, the customer no longer had to worry about lengthy negotiations for each repair job. The fixed pricing ensured that any large-flange repairs would be completed promptly, allowing the customer to focus on their core manufacturing processes without delays.

This type of framework agreement has become increasingly popular among end-users, as it eliminates the need for time-consuming price discussions. Instead of worrying about potential cost overruns or project delays, customers can rest assured that the repair services will be carried out swiftly and at a predictable cost. This predictable service model not only speeds up the repair process but also helps prevent unforeseen maintenance delays that can disrupt production timelines.

FI60E Flange Facing Machine: A Reliable Tool for Flange Restoration

The FI60E flange facing machine is an advanced piece of equipment designed for the demanding conditions of on-site machining in industries such as pressure vessel manufacturing, petrochemical, and oil & gas. With its precision and portability, the FI60E is capable of restoring flanges to their original specifications, ensuring that sealing faces meet strict flatness and surface finish standards. This is essential for ensuring the safe and reliable operation of pressure vessels.

The FI60E’s versatility also makes it suitable for a wide range of applications beyond flange facing. It can be used for flange resurfacing, seal surface repairs, and other critical tasks that require accuracy and efficiency. Its compact design makes it easy to transport and set up on-site, reducing downtime and enhancing productivity.
