Abstract

The invention discloses a disassembly method of a bolt of a threaded locking ring heat exchanger. The disassembly method comprises the following steps that S1, compression bolt penetration, descalingand lubrication are conducted; S2, inner and outer ring compression bolts are taken out; and S3, a locking ring is taken out. The disassembly method of the bolt of the threaded locking ring heat exchanger has the beneficial effects that a loosening rust remover dissolves rusting corrosion dirt, lubricating oil takes the dirt away and lubricates the friction surface, thus friction force between screw thread pairs is reduced, the bolts are taken out conveniently, the bolt taking-out difficulty is reduced, use by people is facilitated, the consumed time is short, the labor efficiency is high, theloss on threads on the locking ring is small, re-disassembly of the bolts is not affected, disassembly portability of the locking ring is improved, meanwhile, the locking ring is not damaged, the disassembly time is greatly shortened, the disassembly working procedure is greatly reduced, and practicality is improved.

Description

technical field [0001] The invention relates to the technical field of bolt removal, in particular to a bolt removal method for a threaded locking ring heat exchanger. Background technique [0002] The high-temperature and high-pressure heat exchangers of hydrocracking and residual oil hydrogenation units in refineries are all threaded locking ring heat exchangers. This kind of heat exchanger has its unique advantages. A large flange and a corresponding set of heavy-duty bolts, but a large threaded locking ring to bear all the pressure. In addition, the bolts that compress the gasket only provide compression force for the gasket, which has almost nothing to do with the internal pressure of the heat exchanger. And if the gasket leaks during operation, there is no need to stop the work, just tighten the outer compression bolts according to certain rules to meet the sealing requirements, because its structure can ensure good sealing and safe and reliable operation, so this kind...
