Tools for chemical plant maintenance
Thread Content
I would like to ask the experts here: do the maintenance workers in your factories use electric wrenches? Does it help improve work efficiency?
In factories, there are more pneumatic wrenches, I guess
It depends on what task needs to be done; tools that are easy to use save time and effort, but it’s not the case that the more advanced the tool, the better it is
For applications that require a specified torque value and use larger bolts, an electric wrench is better – it’s far superior to a sledgehammer
We have seen an improvement in efficiency, as long as one gets used to using it. .
The reactor heads are all powered electrically; it’s too laborious to break them manually
Electric wrenches are used in situations with many fasteners; they save effort, improve efficiency, and ensure high-quality installation. Examples include: heat exchange, reaction, tower equipment, etc.
Electric hydraulic wrenches and pneumatic wrenches. Pneumatic wrenches are fast. Hydraulic wrenches are slow, but they provide even torque.
What kind of chemical plant is this? Most chemical plants contain flammable and explosive substances; even phones are not allowed inside the facilities, and generally the client will not agree to that； As for electric power, you need to obtain a fire permit and a temporary power use permit, as well as find a distribution box (it’s not possible to just attach one directly to the wall). If it’s on a tower or at a platform on the second floor or above, a few wrenches will be enough to get the job done quickly; using this method is rather troublesome ； If it’s a rechargeable type, the torque isn’t very high; it’s not tight enough like that of a regular board. Pneumatic wrenches (air guns) are much easier for loosening bolts with sizes 46, 50, 55, 60 and above compared to using a hammer; there is also no need to worry about electrical safety. They are often used to remove manholes from towers and large covers of heat exchangers, and they are efficient and practical for unscrewing large nuts ； Electric hydraulic wrenches are useful in situations where it’s not possible to use a hammer or there isn’t enough space for one, and when the nuts are too large to be turned by hand (our company has a set imported from Japan that costs over 200,000 yen – it’s not cheap at all) ； For numbers below 41, iron pliers, impact wrenches, or galvanized pliers will suffice, and it’s relatively efficient
