GE 7FA casing tool rental
Hydraulic casing bolt tensioners and nuts for 7F.03–7F.05 combustion, hot-gas-path and major inspections.
See tooling →Hydraulic closure nuts and casing bolt tensioners for GE 7FA, GE 7EA, GE D11 and Siemens/Westinghouse 501F, rented from Cleveland, TX with our own TFAs to install, operate and remove them during your outage.
A turbine casing hydraulic tensioning kit replaces heat or torque on the horizontal joint with controlled, simultaneous hydraulic load. Hydraulic closure nuts or tensioners are fitted to the existing studs, connected through hoses and manifolds to an air-driven pump, and pressurized in sequence so the flange faces close evenly. No casing modification, no bolt heating.
GIMAN Energy LLC rents Boltight® kits configured for each frame and sends its own field technicians (TFAs) to run them. We also execute the Nord-Lock / Superbolt 4-way joint solution on the 501F fleet: 26 installs across North America in 2025–2026.

| Power & distribution | Air-driven pump, manifolds, tee blocks, link hoses, in-line gauges and stop valves |
| Documentation | Manufacturer procedure, calibration records, field service report |
| People | Optional: our own TFAs on site for installation, operation and removal |
| Logistics | Custom transport cases; shipped from Cleveland, TX; temporary import for Canada and Mexico |
Hydraulic casing bolt tensioners and nuts for 7F.03–7F.05 combustion, hot-gas-path and major inspections.
See tooling →Hydraulic nuts and tensioners for the Frame 7E/7EA horizontal joint: peakers, cogen and older combined cycles.
See tooling →Boltight D11 Hydraulic Closure System: 60 nuts 2-1/2" to 7", 80 hoses at 2,500 bar, for tops-on/tops-off and clearance checks.
See tooling →Field execution of the Nord-Lock / Superbolt 4-way joint fix on Siemens/Westinghouse W501F (FD3/FD4).
See tooling →You send unit, frame revision and outage window. We confirm kit availability, match nut sizes to your bolt schedule and ship from Cleveland, TX.
Our TFAs run the site induction, verify the tooling against the casing and set up pump, manifolds and hoses per the manufacturer procedure.
Hydraulic load is applied in sequence and monitored on gauges. Readings and any deviations are recorded with your outage team.
Tooling is inspected, packed and returned. You receive the field service report and calibration records for your outage file.
Based in Cleveland, TX. Registered on GE Vernova / FieldCore's SAP Business Network and prequalified in ComplyWorks (score 98, Severe class).
Part of the 26 4-way joint installs delivered on the North American 501F fleet in 2025–2026 took place in Canada.
Bilingual crews (EN/ES). Quotes in USD; temporary import coordinated with your customs broker or importer of record, project by project.
A kit of hydraulic closure nuts that temporarily replace the top nuts on part of the casing studs. Connected through hoses and a manifold to a pump, they close the horizontal joint uniformly for clearance and distortion checks or tops-on / tops-off, without torque tightening or bolt heating.
No. The kits are direct retrofits sized to the existing studs and casing geometry. The lower nuts stay as standard.
It can. GIMAN Energy deploys its own TFAs to install, operate and remove the tooling and to support the outage team, or ships the kit to your crew with the manufacturer procedure.
GE 7FA (7F.03 to 7F.05), GE 7EA (Frame 7E), GE D11 steam turbines and, through the Nord-Lock / Superbolt 4-way joint solution, Siemens/Westinghouse W501F (FD3/FD4). Each frame has its own kit sized to its stud range: send your bolt schedule and frame revision and we confirm fit before shipping.
Closure nuts temporarily replace the top nuts on part of the horizontal-joint studs to close the flange faces for clearance checks or tops-on / tops-off, as on the GE D11. Casing tensioners stretch each stud axially so the nut is run down by hand and every stud gets the same preload, as on the 7FA and 7EA casing.
An air-driven pump feeds the tooling through manifolds, tee blocks and link hoses, with in-line gauges and stop valves so pressure can be read and controlled during the sequence.
The manufacturer procedure and the calibration records travel with the kit. When GIMAN technicians (TFAs) run it, you also receive a field service report with as-found / as-left readings for your outage file.
The kit for your frame (hydraulic nuts or tensioners, hoses, pump, manifolds, gauges and adaptors), the manufacturer procedure, calibration records and, if you choose it, our own TFAs to install, operate and remove the tooling.
By project: kit rental, TFA days, mobilization and consumables as separate line items on the RFQ. Rate card on request. NDA available; POs through SAP Business Network or directly.
Yes. Our scope is the hydraulic tooling and its operation; cover lift, rigging and overall outage coordination stay with your prime. We align the sequence with your outage manager before mobilization.
Yes. Canada and Mexico / Latin America are quoted per project in USD, with temporary import handled together with your customs broker or importer of record.
Send us the unit, frame revision, bolt schedule and outage window. We come back with availability and a project quote.
