When the casing comes off, every hour of critical-path delay is megawatt-hours your plant can’t sell. Conventional torque methods stress the studs, mark the joint and still leave the flange leaking when you bring the unit back online.
We bring the Nord-Lock Group’s Boltight hydraulic tensioning system directly to your site, with technicians trained on each turbine model. The bolts are pre-loaded uniformly, the joint seals on the first start-up, and the kit goes back on the truck on day three.
Because we own a fleet of kits in Laredo, TX — not borrowed from corporate — we can mobilize on outage windows that don’t fit anyone else’s schedule.

Full 4-Way Joint solution: hydraulic closure system, Superbolt MJTs, CamAlign cylinder alignment tool and Inconel internal seal. Stops the chronic combustion-air leakage that plagues aging 501F units.
Hydraulic tensioning sized for the 7EA frame — peakers, cogen and older combined-cycle units that still need clean, repeatable closures.
Closure kits for the D11 horizontal joint. Built for the bottoming-cycle steam turbine and large reheat units in nuclear and combined-cycle plants.
Tools, hoses, pumps and TFA technicians (typically 4 on-site) leave Laredo within 48 hours of a confirmed PO. Site safety induction with your HSE team on arrival.
Typical scope is 3 days: bolt and Superbolt inspection, hydraulic system installation, casing closure or 4-Way Joint procedure, internal seal placement (501F), final torque verification and protective caps.
Equipment cleaned, packed and removed. Your work area handed back. Service report and photo documentation delivered.
We mobilize across the continental US for combined-cycle, peaker, cogen and steam-cycle outages. Frequent corridors: Texas, Pennsylvania, Florida, California, Arizona, the Carolinas and the Midwest.
We operate the Boltight hydraulic tensioning fleet under a direct equipment agreement with Boltight, Inc. and execute installations using Nord-Lock Group’s published procedures.
With a confirmed PO, our standard mobilization is 48–72 hours from Laredo, TX to most US combined-cycle sites.
Both. A typical job is 4 TFAs on site for ~3 days plus the full hydraulic kit for the unit being serviced.
FD3 and FD4 frames. Talk to us if you operate an earlier FD2 — we’ll evaluate compatibility.
Currently the fleet operates within the continental US under our equipment agreement. For projects outside the US, please contact us directly.
