Before we start – my personal and our special thanks to: Mrs. Johanna Erbacher Produktmanagerin | Digital Cooperations Industrial generation network Vogel Communications Group GmbH & Co. KG - Würzburg http://www.vogel.de Mrs. Beatrix Stagl Teamleiter Operations industrial generation network ngn – new generation network GmbH - Berlin Website: www.industrial-generation.network The two ladies are doing an excellent job !!! Thank you very much for your great support !!! 15.05.2020 2
Facts about bolting application in the industry Regular inspections and maintenance are necessary in order to avoid costly system failures and to ensure operability. Bolted joints must also be checked to determine whether there are any impermissible changes compared to the approved version. Checking the preload is an essential test criterion, because self- loosening of bolt-joints is a high safety risk. That means short and therefore expensive inspection intervals on bolt-joints. 15.05.2020 3
Facts about bolting application in the industry The knowledge of the real preload force-time behavior of planned preloaded bolting-connections enables the design and construction of low-maintenance /-free bolt connections for the industry. That means: Operating costs can be reduced through longer inspection intervals, costly checks can be reduced, or the replacement of complete bolt-joints can be prevented. That means: The work and plant safety as well as the operating costs of bolting applications in the industry can be significantly optimized, whereby a more cost-effective generation of bolted products is achieved. 15.05.2020 4
Torque-controlled bolting Where does the torque value originate from ? But bolt manufacturers also give recommendations for torque values, which is then used as a technical specification. 15.05.2020 5
Torque-controlled bolting Where does the torque value originate from ? Or the torque values are calculated after Norms and Standards like here for the oil and gas industry. (schettki@rohr2.de) 15.05.2020 6
Why can bolt-joints fail?
Technology as a factor!
- Incorrect design and calculation of the bolt-joint
- Low strength of the nut or bolt (quality)
- Thread tolerances too big
- Slight inclination of the Nut contact surface
- Reaction problems when tightening or loosening nuts and bolts
- The coefficient of friction is too low or too high
- - due to impermissible additional lubrication of the
individual components
- due to incorrect application of lubrication
from the bolt manufacturer
- when bolts and nuts get moist / wet lubricants tend
to absorb water
- due to improper transport and storage the bolts and nuts

Conclusion: To tight or to loose a bolt-joint
connection is a complex process! (see Ishikawa-Diagram)

VDI – Statement (Verein Deutscher Ingenieure)
„However - The high standards set for industrial bolting in
terms of process capability and legal safety requirements are
already becoming higher today and are predetermined to
become even higher in the future. As early as during the
planning phase, the responsibility for choosing the right bolting
technology to meet the respective bolting case is delegated to
developers. That choice has an immediate effect on the
technology to be used, process and quality assurance and final
product liability – while all this is subject to profitability
pressure”

15.05.2020 23How about saving costs and increasing quality? …to reduce costs and increase quality at the same time! And this is where standard-bolted joints bear a great, so far untapped potential by using new mobile and intelligent bolting systems, which are being operated and tested and suitable for on-site applications. 15.05.2020 24
Saving costs and increasing quality by using hydraulic yield-point controlled tigthening Mobile hydraulic yield point controlled tightening This takes advantage of the fact when tightening bolted joints by means of mutual torsion of the nut and the bolt not only axial, but also torsional stress is applied as a result of thread friction. Yielding of the bolt starts when the reference stress of tension and torsion reaches the material’s yield point. Immediately after the preload is applied, 50% of the torsion in the bolt is reduced. Therefore, the reference stress decreases, while the preload remains and the yield point controlled preloaded connection re-gains an elastic condition. 15.05.2020 25
What does yield point controlled tightening mean ? When the term "yield point" is used in the context of bolt- joint connections, the material’s yield point is actually meant. For technical materials, the Rp0,2 proof stress or elastic limit Rp0,2 is usually specified instead of the yield strength. Fact is: with a reliable hydraulic yield point controlled tightening process: - bolt joints can never break - There is always sufficient elasticity. - That means always sufficient reserve in the bolt joint 15.05.2020 26
Quote from “Schraubverbindungen” [bolted joints] 4th edition Springer Verlag Heinrich Wiegand, Karl-Heinz Kloos and Wolfgang Thomala Plastic tightening of bolted joints by means of yield point exceeding assembly methods (yield point and angle controlled tightening) is used with increasing success. It allows for an optimum use of the bolt during tightening and leads to maximum possible assembly preloads (chapter 8). The plastic deformations occurring should, in any event, be limited to the uniform elongation range. As high-strength bolts with grades 8,8 to 12,9 have sufficient toughness properties, they can, in general, be preloaded into the partially plastic deformation range without any risk. For the following reasons, it can be assumed that the operational durability of the connection is not only influenced, but significantly improved during tightening in the plastic area. 15.05.2020 27
Quote from “Schraubverbindungen” [bolted joints] 4th edition Springer Verlag Heinrich Wiegand, Karl-Heinz Kloos and Wolfgang Thomala ... but significantly improved: + Because of the elastic springback of the bolts after assembly, the torsion stress applied during tightening is partially reduced not only in the clamped components, but also in the bolt. This releases stress reserves for later operational loads. + With the elongation process in the bolt and nut thread while the preload is applied and exceeding the yield point, an even distribution of the thread load is created, at least a part of which remains even after releasing to the elastic range. + If further plasticizing of the bolt should occur due to the operating force FA, the bolt load relaxation FZ, which is always linked together, will put the connection back into the elastic range. 15.05.2020 28
Quote from “Schraubverbindungen” [bolted joints] 4th edition Springer Verlag Heinrich Wiegand, Karl-Heinz Kloos and Wolfgang Thomala In case of subsequent vibration stress at a preload force level below the yield point, even higher durability values can be achieved for the bolted connection due to more favorable load distribution and possible load-indicated residual compressive stress. This holds true for bolts rolled both, before or after heat treatment. 15.05.2020 29
What does yield point controlled tightening mean ? In other words (source: Schraubfachausbildung [industrial bolting training] DSV) In assemblies in the plastic range, which are used more and more often, the bolt’s yield point is consciously exceeded. Two special features are of importance: Due to loss of preload as a result of embedding, the bolts are still in the elastic area (springback; often evaluated as critical if there is no experience with assembly in the plastic range, but actually well-established for years). The decrease in torsional stress during operation creates an increased yield point, i.e. new load reserves are created (therefore, a plastically assembled bolt is absolutely failure safe). 15.05.2020 30

How does hydraulic yield controlled tightening (SGA) work in practice? In order to fasten HV bolted joints with yield point controlled tightening in a process-reliable way in the field, and to meet all the requirements from VDI/VDE2862-2 in the sense of Industry 4.0, a mobile, practical, hydraulic tightening system is made up of a process and documentation pump combined with standard hydraulic torque wrenches with angle sensors which record, analyze and monitor all tightening processes. 15.05.2020 32

Statistical SGA evaluation of the values applied individually from bolt to bolt:
linear slope; Torque and Angle of rotation
1). The Reason - here: Significantly increased
coefficient of friction recognizable by the linear
gradient (Nm per degree) (Bolt No. 14 can be
recognized by the X axis)
2). The Consequence / Result - here: increased
torque recognizable by the torque statistics (Nm)
(Bolt No. 14 can be recognized by the X axis)
3). Indication of the location of the process-failure
(Bolt No. 14) Here: in the bolt thread because of higher
torsional stress. SGA switches off due to the
comparative stress (= torsional stress + axial load).
Can be recognized by the angle of rotation statistics (°)
15.05.2020 41Advantages of hydraulic yield point controlled tightening a). Tightening factor αA Does not apply for the yield point controlled tightening, because it is not possible that bolted joints can break. Please see VDI-2230 November 2015 Table A8, page 120 – Comments. So it can be calculated by αA = 1,0 b). Max. preload force: Due to the tensile and torsional stresses, the bolt reaches its individual yield point during tightening. As the torsional stress discontinues at the end of the tightening process, a preload force of approx. 90% of Rp0,2 is reached. c). Independent of friction value: Every bolt is stressed to the yield point independent of the friction. Different thread friction coefficients merely lead to a change of the torsional stress in the bolt. d). No customized bolts required: The tightening method can be applied both on the bolt head as well as on the nut. 15.05.2020 42
Advantages of hydraulic yield point controlled tightening e). Reusable: As the method safely switches off before Rp0,2, the bolts can be reused. f). Selection of different bolt manufacturers Bolts and nuts from different manufacturers can be mixed. As each bolt is tightened to its individual yield point, there are no limitations when it comes to choosing the bolt suppliers. g). Lowest relaxation As all components are constantly in a state of force flow and an especially high preload force is reached, this tightening method has the lowest relaxation. h). Accepted method Yield point controlled tightening is accepted by all certifying bodies and in VDI-2230. 15.05.2020 43
Advantages of hydraulic yield point controlled tightening
h). Meets VDI/VDE2862-2
Meets the requirements of VDI/VDE2862-2 for tightening bolted joints.
i). Documentation in the sense of industry 4.0:
Each tightening process is documented with torque and angle
in the form of text and graphics and with a statistic.
j). Quality control:
Not only the bolt, but the entire joint is “measured” during tightening, quality
deviations are detected immediately.
k). Fatigue strength
Due to the high preload level, the joint’s fatigue strength also increases.
l). Process-reliable tightening
even of varnished components.

Saving costs and increasing quality by using hydraulic yield-point controlled tigthening 15.05.2020 46
Saving costs and increasing quality by using hydraulic yield-point controlled tigthening With the right, process-reliable hydraulic yield-point controlled tightening method, - bolted joints can have smaller dimensions. - the number and diameter of bolts can be reduced. - standard HV bolted joints can be used. Conclusion: No more customized bolts are required. - standard HV bolts can be re-used. - standard HV bolts from different manufacturers can be mixed. - the fatigue strength of the connection can be increased. - tightening can be done in accordance with the requirements of certifying and auditing bodies. - tightening can be done in accordance with the directives (ISO; VDI-2862- 2, etc.). - tightening can be documented with absolute quality control. - existing standard hydraulic torque wrenches can be used. 15.05.2020 47
Saving costs and increasing quality by using hydraulic yield-point controlled tigthening Conclusion: With the right process-reliable, mobile tightening methods: Components can be designed more easily and in smaller dimensions, and thus, be produced in a much more cost-efficient way. Together with an expertly, fatigue-endurable design of the connecting components, low-maintenance /maintenance-free standard bolted joints are possible with standard tools. The purpose of bolted joints is achieved: Two or more components are connected in such a way that they act as one component under any operating forces. 15.05.2020 48

Because:
- A sufficient preload force can only be applied in a process-reliable
manner with yield point controlled tightening.
- This creates a flow of forces in the coated joint.
- Possible sliding in the joint resulting in consequential damages and a
failure of the connection are prevented by the created frictional
connection from the beginning.
- Many of the examined coating layers were undamaged.

e.g. after 4 years.
Checking of torque values on already tightened bolts. Suitable for on-site use
due to the ability of measuring further turning of the bolts
In certain intervals bolts have to be checked.
With this method it shall be determined which torque value is needed to turn the
nut/bolt. Even though, a bolt was tightened with a specified torque value 4 years ago,
for example.
28.04.2020 51Sampling inspection of torque values on already tightened bolts
e.g. after 4 years.
This method is suitable according to VDI/VDE 2645 Part 3. Here, the pre-torque is
about half of the previously specified torque value. The angle value is usually set to
about 5° bis 10°. Based on the graphs, one can see at which torque value the nut/bolt
started to turn. This method of checking torque values is a recognized method of
testing in the mechanical engineering field according to VDI / VDE 2645 Blatt 3.
This Torque & Angle-Star method consists of a process and data recording pump
