Features and Benefits:
Bolttech is known for solving the toughest bolting problems found in the industrial world today. These basic practices go into every design and manufacturing detail of our stud tensioning line of tools. We design our tensioners with quality, simplicity and versatility of the specific application and user in mind. Bolttech's Delta Series bolt tensioners maximize efficiency and minimize size for specific single stud size applications.
- Patented high pressure/low friction seals are designed to outlast the competition and provide accuracy within .5% with a calibrated pumping unit.
- Environmentally friendly, using water-filled tensioning systems.
- The direct axial load is applied to the bolt and inaccuracies created through friction are alleviated.

The RotaBolt® range provides you with either finger-tip, visual or remote measurement of tension throughout the life of the bolted joint. They surpass traditional tightening methods such as:
- Hydraulic Tensioners
- Flogging
- Torque Systems
which have severe control limitations and can result in unpredictable bolt tension and joint failure.
RotaBolts are setting new safety standards in a wide variety of sectors where joints are subject to fatigue, vibration, pressure containment and structural slippage.

The STS stud bolt tensioner range is designed for topside operation in a wide variety of applications including pipeline flanges, heat exchangers, pressure vessels, compressor covers, boiler feed pumps, anchor bolts and many others. The range comprises of 23 imperial and 29 metric models, all suitable for working pressures up to 1500 Bar. Imperial models cover all standard bolt sizes from ¾" to 4", metric versions (detailed on page 93) are available for bolt sizes from M16 to M100. Each of the hydraulic cylinders can be used with a variety of interchangeable nut rotating sockets and threaded pullers, available as individual parts or as convenient conversion kits (see pages 94 and 95 for more specific details). This will ensure that the maximum number of bolt diameters can be accommodated using the minimum number of cylinders. All Hi-Force hydraulic stud bolt tensioners are designed and manufactured to include a wear coated piston, maximum piston stroke indicator, self-energising high pressure seals, dual quick connect couplings for easy multiple tensioner connection and a user friendly operation and maintenance procedure. Additional or spare bridges, threaded pullers and nut rotating sockets can be supplied as and when required.

SEWN ROUND BELLOWS
These are used when strong rotation resistance is required (for instance, to cover ball screws) and where a
very compact closed pack is required.
• Highly reliable bellows
• No tooling costs
• High resistance to mechanical and dynamic stress
• With selected edging (in safety colors upon request)
• Resistance to coolants and oils
• Minimum internal diameter starting at 20 mm
• Suitable for high temperatures
• Any size external diameter
• Available with guide bushings and reinforcement rings
• Good price/quality ratio
THERMIC WELDED TIGHT BELLOWS
They are used when watertight protection of the components (i.e. screws, shafts, etc.) is necessary against the contamination made by coolants.
• Economic bellows
• Good resistance to chemicals
• Resistance to heat compatible with the used materials (see characteristics on page 46- 47)
• They can be supplied in a variety of geometrical shapes, with low cost production of moulds (if not already present in our stock)
Heat-Formed Bellows
These are used when high mechanical strength and
heat resistance are required.
• Excellent resistance to mechanical stress
• Also available cone-shaped
• Resistance to coolants and oils
• No tooling costs
• Available with guide bushings and reinforcement rings upon request
• Suitable for high temperatures
Open Head-Formed Bellows
Upon request with longitudinal opening seam when the bellow must be disassembled without dismantling the part to be protected

Bellows
Arnold bellows offer safe protection for both people and machinery. These are the products to soke your problems - in which material, stability and shape can be individually customised.
If the bellows will be subjected to high mechanical stress and strain, the telescopic covers provide safe protection even at high processing speeds. Due to our patented mounting system, the telescopic covers will either be flexibly mounted or connected with the bellows without the use of adhesive materials under consistent counter pressure, if required and can also be coolant-compatible, if this is desired.

In some critical bolting applications, factors such as friction or bolt/joint geometry are such that the measurement of applied torque alone will not provide the degree of accuracy necessary to control the preload within the required limits. Likewise, many critical applications also demand that bolt preload be monitored over the service life of the fastener as part of a predictive or preventative maintenance program. In these applications, ultrasonic measurement of fastener elongation and/or load has frequently proven to be the most accurate, reliable and cost effective solution.
Ultrasonic measurement of bolt preload is made possible by introducing a sonic pulse at one end of the fastener and accurately measuring the time of flight (TOF) required for the echo to return from the opposite end; using material constants, the USM-II converts this TOF into an "ultrasonic length" of the fastener, providing a baseline from which future measurements will be made. When the fastener is tightened, the TOF increases and the USM-II will again utilize material constants to eliminate the effects of stress and temperature variations on sound velocity, providing an accurate elongation or load measurement.
The USM-II uses state of the art hardware and software to achieve these measurements with maximum automation, and minimizes the need for operator interpretation. Offering digital recordation and transmission of data, as well as calibrated analog signal output the USM-II provides a complete system for measurement, recordation, and control of fastener tension in the most demanding applications.

TesT 205 screw testing machines were newly developed based on the
experience of many years and essentially consist out of 4 components:
- 1 force/torque transducer
- 1 machine frame with regulated drive, angle measurement and table
- 1 PC with integrated data acquisition board and motor control
- 1 Software package
The evaluation takes place in real time processing and online during
the test sequences. The force/torque transducer is patented. Its shaping permits the measurement of the 3 quantities: total torque, head friction torque and clamping force without influence of one quantity by one of the others.
Sequences can be programmed by yourselves using the general instructions existing in the software. The available finished software packages according to international standards or standards of the car manufacturers can be adapted to the individual desires of the user at any time.
