Bolting Question
Bolting Question
(OP)
I work in a power plant and we often have trouble with large bolting galling or seizing up especially during disassembly. It looks like most of the bolting was assembled with no type of dry or paste anti-seize. I understand the high temps encountered and that lubricating the threads can effect torquing of fasteners or using the wrong type may cause more problems than solving if it turns to carbon, hardens, etc.. Most of our critical bolting is checked for stretch though and not specific torque value. Why the apparent use of no lubricants, break free, or other magical elixirs to aid in disassembly or assembly for that matter. Seems better than ending up using large nut splitters and replacing galled studs, etc.?





RE: Bolting Question
In some applications there is not a good anti-seize to use, and using the wrong one is a disaster.

Where is the documentation of the valve?.
Please, search a complete information and then tell us (service temperature, washer material, etc ).
