FI80 ID Mount Flange Facer for On-Site Heat Exchanger Repair
Projects
CASE INTRODUCTION
Zhejiang Petrochemical (ZPC) is one of China’s largest integrated
refining and chemical enterprises, specializing in petroleum
refining, advanced chemical materials, and specialty products. Its
large-scale production facilities and complex process equipment
demand high safety standards, reliability, and sustainable
operation. In the heat exchanger industry, equipment continuously
operates under high temperature, high pressure, and corrosive
chemical environments, which over time can cause sealing surface
wear, leakage, and failures. These issues not only result in
production losses and safety risks but also lead to costly
unplanned downtime.
To address this challenge, on July 7, 2025, Zhejiang Petrochemical
applied the FI80E Flange Facing Machine (ID Mount Flange Facer)
from MT Portable Machine on-site in Zhejiang Province. The
machine’s modular design and portability enabled rapid setup,
precise machining, and efficient maintenance directly at the site,
without removing large equipment. This solution ensured safe,
stable, and efficient operations.
