THT Series Topside Bolt Tensioning Tools

“The THT range of bolt tensioning tools are some of the most compact and reliable tensioners available today.”

The THT range of topside bolt tensioning tools we supplying consist of 6 base tools covering bolt Imperial sizes from 3/4" to 4"and Metric from M20 to M115. 
The tools are designed to fit on to most ANSI B16.5, ANSI B16.47 Series 1, MSS-SP44, API-6A and API-17D flanges. 
Each base tool can be converted for use on a different bolts size by the use of our conversion kits. 
Refer to the specifications at the catalog for part numbers and more information.

Seal Reliability

Seal reliability is a fundamental requirement. All tensioners have polyurethane self-energizing lip seals requiring no adjustment. The seals ‘snap fit’ into the piston housing, remain firm and will not dislodge to cause failure after prolonged use. As the seals are machined and not molded, size is not restricted, allowing no compromise in tensioner design. The supplied seal exhibits a much lower coefficient of friction than nitrile seals used in many other hydraulic bolt tensioners. This benefit, in conjunction with a special anti-extrusion device, allows the tool piston/ram to be returned to its closed position with minimal effort.

Link Hose System

One of the many advantages of hydraulic bolt tensioning is the ability to link a number of tensioners together and load simultaneously all the bolts on a joint. Although this gives excellent load distribution, an enormous variety of flexible hose assemblies are necessary - which confuse the user. To overcome this problem we offer a single assembly called a ‘Link hose’. This length of flexible high pressure hose, fitted with male and female quick connect couplings at opposite ends is fast and an economical method of connecting multiple tensioners together - the number of hoses required is the same as the number of tools to be linked - a simple formula to remember.
