Flange Facing Machine Solves Challenging Pipe Beveling Task for Nuclear Industry

In the world of on-site machining, the job is always full of challenges. Tight timelines, limited space, tough-to-machine materials, and stringent accuracy requirements make completing the task even more difficult. However, the satisfaction that comes from solving a customer’s problem with portable machining equipment is unmatched. This is especially true when working with industries that require high precision and demanding standards, such as the nuclear sector.

As a leading supplier of portable machining equipment, MT Portable Machine has been called upon again by a client in the nuclear power industry. Their request was specific: to machine a bevel with extremely high surface finish and tight dimensional tolerances on a thick-walled pipe. Traditional beveling machines were simply unable to meet the challenge, particularly when it came to machining thick-walled pipes made of tough materials like stainless steel.

In response to this demand, MT Portable Machine extended the capabilities of its FI60E Flange Facing Machine by adding a bevel extension tool holder. This enhancement allowed the machine to carry out bevel cutting with a vertical automatic feed function from the flange facing machine's tool post. While the process is slower than conventional methods, it provides an exceptional surface finish—reaching a roughness value of Ra1.6 or even higher. This high surface quality is especially crucial in industries such as nuclear power, where precision is critical.

The client sent a sample of the pipe, made of 316L stainless steel, to MT Portable Machine for testing. After extensive testing and adjustment, the team successfully completed the bevel machining. The results exceeded the client’s expectations, proving that the combination of the extended tool holder and the FI60E Flange Facing Machine was the perfect solution for this complex task.

Not only does the FI60E Flange Facing Machine excel in flange surface repair, but it is also versatile enough to handle beveling and chamfering tasks. Its ability to provide precision machining in challenging on-site conditions has made it a valuable asset in industries where high-quality standards are paramount.

This case is just one example of how MT Portable Machine continues to innovate and support its clients by offering practical solutions that meet real-world machining challenges.
