A turbine casing stud that has not moved in 15 years can derail a planned shutdown fast.
Industrial Bolting uses
induction bolt heating to expand fasteners from the inside out, without hammering, torching, or putting nearby components at risk. Our crew brings portable equipment directly to your outage or maintenance site. The work stays controlled, and your repair can move to its next step.
We Heat Fasteners From the Inside
On a large flange, open flame can spread heat well beyond the bolt that needs to come out. We place induction coils around the fastener and concentrate electrical heat where it does the most good. The bolt or stud expands quickly, which loosens the grip caused by corrosion, heavy load, or years in service. In many cases, threads survive when rough removal methods would have ruined them. We handle induction bolt heating for major bolting work where temperature control counts.
- Targeted heat: Energy goes into the fastener, not across the full assembly.
- Cleaner removal: Less striking, grinding, and cutting near critical equipment.
Removing Seized Bolts Without Damage
When a corroded stud finally starts to expand, the difference can be immediate. We heat the fastener until it releases its hold, then remove it with measured force. Our crew watches adjacent surfaces, threads, and flange faces throughout the work, so maintenance can continue without an avoidable repair.
Every Setup Gets Matched to the Hardware
Turbine casing bolts, corroded studs, and heavy flange connections each need their own setup. We match coil size to the hardware, manage heating cycles, and work around your onsite schedule. If mechanical separation is needed, we can also bring
hydraulic nut splitters to the job, keeping the process precise rather than destructive.
A Simple Process From Start to Finish
Our process stays consistent from job to job. First, we assess access, fastener condition, and the surrounding assembly. Next, we apply controlled induction energy right at the work location. Finally, hardware comes free while our crew checks threads and component condition. At 2 a.m. during an outage, one seized bolt can hold up an entire crew, and our team arrives ready for stubborn hardware. We also handle
tool repair when equipment needs to get back in service, since a damaged fastener should not turn into a larger repair.
