Nut Splitting
Exposure to extreme conditions can cause nuts to gall, corrode or become seized. Team’s Nut Splitting Service is a proven method for quickly and safely removing such nuts without causing damage to the threads. |
Stud Removal
In most cases, damaged or seized studs can be removed by Team technicians using special stud removal tools. When studs cannot be removed, Team’s Field Machining Services can drill out studs without damaging body threads. |
Turbine Bolt Heating
|
De-tensioning and tensioning of turbine bolts. Typical heating time is two to eight minutes per bolt, resulting in significant time saving for client.
|
Nut Heating
|
Fast heating of nuts on Hydro-Cracker flanges, Reactors, and Exchanger heads allow for quick dismantling of components. Typical heating time is 30 seconds to two minutes per nut. This application helps to eliminate bolt thread damage.
