8. 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
9. 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
10. High Pressure power oil FORCES Piston and Nut Body apart HiTemp Hydraulic Nut
11. 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
12. High Pressure power oil Hi Temp Hydraulic Nut FORCES Piston and Nut Body apart
14. 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
16. Full Load is applied to Locking Ring Hi Temp Hydraulic Nut
17. When oil is removed, tightening operation is completed by removing High Pressure system, and glands from Nut-body. Hi Temp Hydraulic Nut
18. When oil is removed, tightening operation is completed by removing High Pressure system, and glands from Nut-body. Hi Temp Hydraulic Nut
19. 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
21. 32 x 1 ¾” HiTemp Hydradraulic Nuts – tensioned in less then 2 hours!! Hi Temp Hydraulic Nut
22.
23. 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

26. 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
27. 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
28.
29. 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
30. 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
31. 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
32. 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
33. The Solution!! Load is transferred from each thread, through the cone interface, down to the nut to casing contact area
34. 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
35. 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
36. OIL in Tighten inner part of nut until it is snug with the outer cone The Titan Solution!! CASING Spot Face
