1 P&S Vorspannsysteme AG : Tensioning Systems SUPERBOLT Your trustfull partner for : - High technology by mechanical threaded tensioners - High pre-load, and/or big bolting systems, - Precision & Security at first Presentation P&S Superbolt SOFT Porto September 2010 / RD 1

2 P&S Tensioning Systems SUPERBOLT : Localisation P&S Vorspannsysteme AG Rietwiesstrasse 2 CH-8735 St. Gallenkappel Switzerland Tel. +41-(0) Fax. +41-(0) info@p-s.ch Presentation P&S Superbolt SOFT Porto September 2010 / RD 2

3 P&S Tensioning Systems SUPERBOLT in M. Ploke & M. Steinbock founded P&S in Switzerland and patented Superbolt 2005 Building of the actually manufacture employed for a turnover of 10 millions Building of an additional manufacture to double the capacity of production Presentation P&S Superbolt SOFT Porto September 2010 / RD 3

4 P&S SUPERBOLT : Products Designation Nut tensioners Flex nut Bolts tensioners Thrust collars for ball-bearing Expansion bolts Dimensions Standard : M16 - M160 Special : M8 - S1450 Material Alloyed steel, stainless steel, Nickel, Inconel Quality, 8.8, 10.9, 12.9, Presentation P&S Superbolt SOFT Porto September 2010 / RD 4

5 P&S Superbolt : 100% Swiss made Presentation P&S Superbolt SOFT Porto September 2010 / RD 5

6 P&S Superbolt : Engineering 50% of turnover through specialy, adapted solutions Presentation P&S Superbolt SOFT Porto September 2010 / RD 6

7 P&S Superbolt : Services For all our and your applications we propose : A technical documentation The help of a P&S Technician during mounting, demounting That P&S assemble or disassemble your construction Presentation P&S Superbolt SOFT Porto September 2010 / RD 7

8 P&S Superbolt : Certificates P&S Vorspannsysteme is ISO 9001 through : QS Schaffhausen AG Système Audit Siemens TUV Our technology would be approved through Germanischer Lloyd Det Norske Veritas (DNV) TÜV US NAVY American Bureau of Shipping (ABS) AIB-Abnahme ( Nuclear controlling ) Presentation P&S Superbolt SOFT Porto September 2010 / RD 8

9 P&S Superbolt : easy tools to mounting, dismounting Superbolt : => Easy and practical tools, hand tools is enough => That mean lower tool cost and lower tool place, volume => Great for big bolting system or by high preloads Hrrrmmm! Great! Or with pneumatic tools => Superbolt recommended by difficult access or if you have to mounted and dismounted frequently! Presentation P&S Superbolt SOFT Porto September 2010 / RD 9

10 P&S Superbolt : for example anchorage Superbolt? => Space saving tensioner, great by difficult access! Presentation P&S Superbolt SOFT Porto September 2010 / RD 10

11 P&S Superbolt : Dimension practice Superbolt : a story of jackbolts Recommended for application with large size or needing high preload as example Presentation P&S Superbolt SOFT Porto September 2010 / RD 11

12 P&S Superbolt : can not be disassembly! Because of compression of the hardened jackbolts, Superbolts can pre-load higher that conventional tensioning systems. Because of action of jackbolts on the hardened washer, Superbolt nut can not distight oneself ( with or without vibrations ) Superbolt = security at first! The compression of jackbolt = elasticity of Superbolt in your bolting system. Presentation P&S Superbolt SOFT Porto September 2010 / RD 12

13 P&S Superbolt : Forces OK, but without torsion, friction Qual. 8.8 M64x6 Conventionnel Nm Superbolt 315 Nm Through Superbolt action : - No friction in the thread, - Precision of pre-load from +/-10% for all size Only axial pre-load, no torsion in the bolt Presentation P&S Superbolt SOFT Porto September 2010 / RD 13

14 P&S Superbolt : Interesting by no horizontal platform SUPERBOLT can sure pre-load with axial action until 2 defect, Risk of cracks Only actial pre-load, OK for superbolt Jackbolt! Presentation P&S Superbolt SOFT Porto September 2010 / RD 14

15 P&S Superbolt : ideal force distribution in all threads through elasticity % % % % % % % Cracks through concentration of force in first threads => Homogeneous force distribution in all threads Presentation P&S Superbolt SOFT Porto September 2010 / RD 15

16 P&S Superbolt : Résultats More elasticity = better life by vibrations and/or additional dynamic forces to! Presentation P&S Superbolt SOFT Porto September 2010 / RD 16

17 P&S Superbolt : Compared to other pre-load technology Example : M64x6, Charge max. 0.9xRe ( = max. elasticity limite of steel ) Pre-load through conventional tightening = with torsion effect Pre-load through hydraulic tightening! Do not plastify Pre-load through Superbolt = Be sure. Presentation P&S Superbolt SOFT Porto September 2010 / RD 17

18 P&S Superbolt : remember! SUPERBOLT Products with multi jackbolts for : - all size, without limits tous diamètres de filetage, - all pre-load force, to guarantee, secure : High tightening precision Great to exploit the bolt caracteristics Pre-load without torsion Homogeneous load distribution in all threads Quick to mounting or dismounting (30-60s for M48 ) No lossening of the bolt, Superbolt = sure tightening Easy tools for all size Easy to mounting and dismounting A cheap solution in addition for Nut, tools and mounting time! Presentation P&S Superbolt SOFT Porto September 2010 / RD 18

19 P&S Superbolt : Expansion bolts Force distribution through radial expansion Superbolt Presentation P&S Superbolt SOFT Porto September 2010 / RD 19

20 P&S Superbolt : Usual bolts system Usual bolts Consequence of tightening Thourgh to tightening the bolts reduce the external diameter Presentation P&S Superbolt SOFT Porto September 2010 / RD 20

21 P&S Superbolt : Usual bolts system Consequence of coupling s forces, action reaction from bolt :pzen Through turn mouvement, torque comming from ½ coupling and diameter diefference between bolt and boring, the coupling can slide, skid on of the other => the bolt have only a 4 points contact, and deform the boring. This action could have consequence if the machine accelerated or disacceleret. => Customer hav to change the bolt and re-bore the flange Presentation P&S Superbolt SOFT Porto September 2010 / RD 21

22 P&S Superbolt : Superbolt Solution Conical bolt Superbolt Nut Conical, split sleeve Superbolt nut Strut Presentation P&S Superbolt SOFT Porto September 2010 / RD 22

23 P&S Superbolt : Expansion bolt Mounting and Function Axial Pre-load, so that the sleeve maried the boring on the surface through radial expansion. Through to expansion action, the sleeve bolt are centering the 2 ½ coupling together Block stop calculated by P&S Conicity 1:20 => Radial expansion = precise centring from 2 elements Presentation P&S Superbolt SOFT Porto September 2010 / RD 23

24 P&S Superbolt : Expansion bolt Mounting and Function The 2 elements are centered Tightening from other nut to make the axial pre-load, assembly of two elements => The two elements are centered and tightened Presentation P&S Superbolt SOFT Porto September 2010 / RD 24

25 P&S Superbolt : Expansion bolt Mounting and Function Through to our technology the two elements are working as one elements, without slide, skid possibility => The torque is idealy transmitted Machining tolerance to use Superbolt expansion bolt : +/- 0,1mm between alignment of boring, tolerance < IT8 through machining and <IT11 for the addition of all parameters Consequence : => Bolts quantity can be reduce :1,5 to 2 for the same coupling, and reduce the machining costs, and sure the live of the pieces!...
