Description

Fitting Flange Nut Locating Kit

The invention relates to a nut positioning assembly for a pipe fitting flange, in particular to a nut positioning assembly which can simultaneously and rapidly position all the nuts of all the bolts on the pipe fitting flange at one time.

The common connection and assembly of industrial pipelines is mainly to manually lock and fasten all the bolts on the flanges of adjacent pipe fittings one by one, so as to continuously extend the pipeline connection. Cause the leakage of liquid or gas in the pipe, causing many accidents to emerge in an endless stream, causing very serious casualties and property losses (such as gas explosions and factory fires). Therefore, the locking of industrial pipeline flange bolts is a very important task, and its requirements for construction speed and locking quality are very strict. If the locking is not complete, or the tightening method and the number of pounds are not enough, it will often reduce The reliability of the pipeline causes the risk of leakage when the pipeline transports fluid at high pressure.

In the construction contracts of many industrial pipelines, pipeline pressure test inspections before commencement, as well as the records and reports of checking flange locking will be added. During the inspection, water or air will be used for pressure testing. If leakage is found during the test, It is necessary to perform pressure relief, blowing, step by step verification and inspection of the locking of the joints, maintenance, reinstallation, etc., and then re-test, which will not only waste a lot of manpower, but also prolong the construction completion time. Therefore, the flange bolt locking technology of traditional industrial pipelines has reached a bottleneck point. It is necessary to develop new technologies to overcome this problem and improve work efficiency. Otherwise, it will be difficult to shorten the construction time, reduce construction costs and improve industrial safety.

However, when tightening the bolts on the flange of the pipe fittings, the current practice is to operate manually; when locking the bolts, no matter whether a manual torque wrench or a power torque wrench is used, it needs to be manually continuously tightened. Locking is performed for each bolt, and only one bolt can be locked at a time, which is very inefficient. Furthermore, before locking the bolt, it is necessary to use a wrench to fix the nut on the other side of the bolt, which also makes the overall locking bolt operation more labor-intensive and time-consuming, and will cost more labor costs, and there are artificial The risk of negligence and error (such as wrench dropping or jamming, etc.), is not practical and economical.
