TL-PST SERIES TOPSIDE BOLT TENSIONERS TL-PST SERIES Bolt Tensioners are one of the most light, compact and versatile line of tensioners available. Designed for operation in a variety of Applications including pipeline flanges, heat feed pumps, anchor bolts and many others. The TL-PST Tensioner is very simple to use and consists of four parts-Threaded Puller, Load Cell, Bridge and Nut Driver (Nut Rotating Socket). NUT DRIVER/ THREADED PULLER LOAD CELL VERSATILE DESIGN ROLL ANTI SEALS STROKE INDICATOR STEEL FLOATING PISTON The TL-PST Series standard variable tensioners are designed to provide a wide range of flexibility, covering stud sizes from 3/4” to 5.3/4” (M-16 to M-150). Different stud sizes are accommodated by the same load cell by simply changing the adaptor kit consisting of Threaded Puller, Bridge, and Nut Driver. All TL-PST Series Tensioners are fitted with Anti Roll, Composite Material Seals for longer life and high reliability. The seals used have a low coefficient of friction so that the piston can be returned to a closed position with minimal effort. TL-PST Series tensioners can be provided with machined PU (poly urethane) seats if requested. The TL-PST tensioners have an exceptional stroke of 15 mm. The Integral Stroke Indicator allows the piston stroke to be viewed while tensioning is in progress. A Red line on piston indicates an over stoke ensuring safe operation. The TL-PST series tensioners are designed so that in the event of an over-stroke the high pressure fluid will be released from the inner side of the load cell, thus saving the operator from any potential exposure. The TL-PST Series load cell is provisioned with two connections and this acts as a manifold for multi-tensioning applications. By using high pressure link hoses, any number of bolt tensioners can be connected and used simultaneously. This ensures equal tightening of all bolts on the flange and reduces work time. The TL-PST Series tensioners operate at a maximum pressure of 1500 Bar and are manufactured from high strength aircraft quality AISI 4340 alloy steel parts for long lasting trouble free performance. The unique piston design allows 2° tilt without any loss of load, preventing piston seizure of damage to piston bore.

The nut-driver is placed over the nut (fig.l). The bridge and load cell is then placed over the bolt (fig.2). The Puller is then screwed over the stud protruding above the nut face (fig.3) making sure that at least 1 x diameter of bolt is engaged with the Threaded Puller. Desired hydraulic pressure is now applied to load cell, which stretches the bolt, (fig.4). The nut is turned down using the nut-driver and tommy bar. The Pressure in then released leaving the stud loaded to the desired value.

BOLT TENSIONERS TL-TSS Series Bolt Tensioners are specially designed for subsea applications. These Tensioners are suitable for higher pressure rating flanges also. It’s ergonomic design makes it very easy to handle and use by divers under the harsh sea conditions. These tensioners are designed to provide a wide range of flexibility, covering stud sizes 3/4” to 3.1/2” (M-18 to M-85). The tool consists of two basic parts-Tensioning Unit and Puller Nut as shown.
