Application :
When inserted into a hollow
bolt , the transfered heat causes the bolt to expand and increase in length
, allowing the nut to be further wrenched tightened .
When the heater is removed the bolt cools and contracts , drawing down
further the previously tightened nut. the higher the wattage the faster
the expansion . Used widely on studs and
holding
bolts on large equipments such as steam generators , turbines and pressure
vessels .
Construction :
Sheathed in stainless steel the heaters constructed having a recommended minimum 100 mm cold zone separating the heated zone from the junction box and handle. The element is of the compacted variety , allowing high watts density and long service life .
