Tentec Celebrates Order for Bolt Tensioning System to China’s Fast-Growing Nuclear Industry
Tentec, designers, manufacturers and suppliers of bolt tightening equipment is celebrating a major order for its Multi-Stud Bolt Tensioning (MST) System to the rapidly expanding nuclear energy market in China.
Online PR News – 04-October-2012 –Bolt tightening specialist, Tentec Ltd, is pleased to announce a major order for its Multi-Stud Bolt Tensioning (MST) System to the rapidly expanding nuclear energy market in China. Working closely with HTS, its Chinese agent, the company has secured an order with the renowned Dongfang Electric Corporation for two of its MST systems.
This latest order comprises two MST systems that have been specifically designed by Tentec’s in-house engineering team to tension 20 bolts simultaneously. One of the systems tensions 1˝ “ bolts, while the other has been designed for 17/8” bolts on nuclear manway covers. MST systems are increasing in popularity as the cover can be removed and replaced much quicker and far more accurately than traditional tensioning methods, obviously reducing any risk of contamination.
These state of- the-art systems work by applying a predictable and accurate pre-load to all studs simultaneously, thus eliminating the problems normally associated with conventional torque tightening techniques such as uneven gasket pre-loads resulting in closure leakage, galling and broken fasteners. Hydraulic pressure is applied simultaneously to each segmented stud tensioner. All frictional factors connected with conventional bolt tightening methods are alleviated since a direct axial force is applied to the bolts which generate a bolt elongation. This elongation/tension is permanently retained by means of the application hexagon nuts.
“We have been working very hard with the HTS team to establish our reputation in China.” explains Roy Sheldon, Sales Director at Tentec. “One of the main reasons for our success is that we have been able to demonstrate our long standing expertise in nuclear markets throughout the world. We have been servicing this industry for many years and have numerous installations in countries including the UK, United States and the Far East.”
