In the petrochemical equipment industry, precision and reliability are critical for maintaining operational safety and plant efficiency. Recently, MT Portable Machine successfully completed an on-site flange repair project for one of its long-term partners — a leading petrochemical equipment enterprise. The repair was executed using the FI40E Flange Facing Machine, a high-performance portable machining solution designed for precision flange resurfacing in demanding industrial environments.
The client, a reputable company in the petrochemical sector, has maintained a long-term partnership with MT Portable Machine. Given the complexity of refinery operations, regular maintenance and flange surface refurbishment are essential to ensure leak-free connections and extend the service life of process piping systems. Over time, factors such as thermal expansion, corrosion, and gasket wear can cause flange surface deformation and sealing failure. To resolve these challenges efficiently, the client once again relied on MT’s experienced on-site machining team.

The MT Portable Machine service engineers arrived at the site equipped with the FI40E Flange Facing Machine, well known for its compact design, structural rigidity, and high cutting precision. After a detailed assessment and quick setup, the team performed accurate re-facing of several damaged flanges, restoring them to standard sealing surface conditions compliant with ANSI B16.5 / ASME requirements.
Before delivery, every MT flange facing machine undergoes rigorous factory testing to ensure precision, stability, and performance reliability. The FI40E model features an electric drive system that allows smooth speed control and consistent cutting performance, making it an ideal choice for on-site flange facing tasks in refineries, power plants, and chemical processing units. The outstanding performance of the FI40E once again demonstrated MT Portable Machine’s dedication to quality, innovation, and field reliability.
This successful project further reinforces MT Portable Machine’s reputation as a trusted partner in the petrochemical industry, providing customers with not only durable and efficient equipment but also professional on-site technical support. The company’s skilled engineers are fully capable of handling complex machining challenges such as flange facing, groove cutting, and sealing surface restoration under various operating conditions.
