In order to optimise the individual weight of each segment Tentec MST systems can be profile machine cut to remove unnecessary material.
AXIAL BOLT LOAD
Bolt load is applied axially to the bolts. Inconsistencies such as friction, bending and lubricant are not a factor when using MST systems. No torsional stresses are involved.
MST systems offer an extremely rapid and simple method of simultaneously, accurately tensioning every bolt on a closure flange. A typical applications for MST’s are nuclear manway covers where the elevated radioactive environment demands an extremely rapid tensioning time in order to minimise personnel exposure.
MST systems are removed from the closure once the bolts are loaded. This allows for a single MST system to be used on many identical closure joints.
Bolt load is directly proportional to the pressure applied to the tensioner.
ELLIPTICAL PISTON RAMS
In order to maximise the space between each bolt and to achieve the correct hydraulic pressure area a special non-circular piston ram can be utilised.
SPLIT REACTION NUTS
Tentec quick fitting Split Reaction Nuts can be incorporated into the MST design. These allow for even quicker installation and de-installation times.
Over the years Tentec has developed a class leading high pressure seal technology. This innovative seal technology is industry proven and offers many 1000’s of reliable and safe pressure cycles.
SAFETY & RELIABILITY
Integrated into the design of each MST are enhanced safety features including mechanisms to remove the hazard of over-stroking the hydraulic rams All Tentec MST systems feature a mechanism which directs oil flow away from the operator in the instance the ram is over-stroked and exhausts oil harmlessly into the internal section of the system.
