Hi Temp  Hydraulic Nut
[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Hi-Temp  Hydraulic Nut
Spherical Washer designed to self-correct seating & bolting mis-alignment Piston with external buttressed screw-thread for Locking Ring Locking Ring, to retain Load Nut body, which screws onto the Bolt using purpose designed screw-thread Nut body incorporates high-pressure threaded connections for power oil High Pressure seals contained within Nut body HiTemp  Hydraulic Nut
High Pressure power oil  Inlet  connection High Pressure power oil inlet connection floods the sealed chamber High Pressure power oil  Outlet  is sealed oil in HiTemp  Hydraulic Nut
High Pressure power oil FORCES Piston and Nut Body apart HiTemp  Hydraulic Nut
High Pressure power oil The bolt is stretched accurately so applying the required tension, and providing the desired compressive force. FORCES Piston and Nut Body apart Hi Temp  Hydraulic Nut
High Pressure power oil Hi Temp  Hydraulic Nut FORCES Piston and Nut Body apart
Hi Temp  Hydraulic Nut
Threaded Locking Ring, mounted on Piston, is screwed hand-tight up to the Nut-body, to retain the induced load tension in the bolt. oil pressure released Pressure is released, and oil can be extracted for high temperature applications. Hi Temp  Hydraulic Nut
Hi Temp  Hydraulic Nut
Full Load is applied to Locking Ring Hi Temp  Hydraulic Nut
When oil is removed, tightening operation is completed by removing High Pressure system, and glands from Nut-body. Hi Temp  Hydraulic Nut
When oil is removed, tightening operation is completed by removing High Pressure system, and glands from Nut-body. Hi Temp  Hydraulic Nut
The  Hydraulic Nut  is removed, by the reverse process, which unloads the Locking Ring, allowing easy removal of the Nut-body  assembly No major physical force, large wrenches or torque tools are required to correctly fit and remove the  Hydraulic   N UT Hi Temp  Hydraulic Nut

The size and pitch separation of the Bolts and Studbolts used in securing Turbine casings does not permit the use of regular tooling. Bolting is generally carried out by thermal elongation of the stud & measuring to check elongation. Restrictive Area High Load Requirement Minimal Stud Protrusion Height restrictions in some positions Challenges Hi Temp  Hydraulic Nut
[object Object],[object Object],[object Object],Challenges Challenges  CASING Spot Face
[object Object],[object Object],This creates a problem: The nut to casing contact area is greatly reduced, thus increasing contact  stresses to unacceptable levels  Attempted Solutions Attempted Solutions  CASING Spot Face Slimline Bridge Reduced Nut
To overcome this problem a thick washer is used; thus maintaining the casing contact stress area   This however means bolt has to be made longer!!  Attempted Solutions  CASING Spot Face Thick Washer Slimline Bridge Reduced Nut
The bolt has also to be made longer to accommodate the tensioner IT IS OBVIOUS THIS SYSTEM  REQUIRES A CHANGE OF BOLTING, OFTEN A COST  PROHIBITVE SOLUTION Attempted Solutions Attempted Solutions  CASING Spot Face Thick Washer Slimline Bridge Reduced Nut
[object Object],[object Object],[object Object],[object Object],[object Object],More Problems! The challenges FEA BOLT NUT CASING Spot Face
Tapered threads on the  Bolt as adopted by Westinghouse, MHI, etc.... Tapered threads on the  nut as adopted by GE, Toshiba. etc.... These are the attempted solutions for better distribution of stress in the threads Attempted Solutions SOLUTIONS WHICH HAVE BEEN PROVEN COMPLETELY  INEFECTIVE Attempted Solutions  CASING Spot Face
Slide on outer cone of nut Screw on inner cone nut Slide on tensioner bridge Machine taper thread in bolt Screw on one piece tensioner No Stud Replacement Nut to casing contact stress area is  maintained as per  the original nut The Solution!! The Solution CASING Spot Face
The Critical Interface Note the smooth & even distribution of load from the high strength puller to the studbolt No part of the studbolt is overstressed Puller stud loads do not exceed allowable maximum F.E.A. The Solution
STRESS  IS DECREASED ACROSS THE SECTIONAL AREA Stress THE MODIFIED STUDBOLT HAS A BETTER DISTRIBUTION OF STRESS THAN STANDARD SECTION 1 SECTION 2 2601.4 2441.0
The Solution!! Load is transferred from each thread, through the cone interface, down to  the nut to casing contact area
Longer Bolt Life No Thread Distortion Dramatically less creep  induced failure Disassembles easily Outer Cone provides stable  platform for HydraJac Tensioner Gives evenly distributed compressive load across the spotface SUPERIOR  CONE NUT  CHARACTERISTICS Benefits
OIL in Apply Oil Pressure Note both oil chambers now  under pressure Also note bolt is now stretched And outer part of nut is clear from inner part The Titan Solution! CASING Spot Face
