The term jacket refers to insulators that are used for covering processing components. These components vary a lot and they include filters, pumps, valves, pipes, and accessories. The main purpose that jackets are used to serve is to provide thermal insulation. The cover is wrapped around the item by joining hooks firmly together using ropes. This setup is to be maintained as long as the item is in use.
There exists a broad spectrum of products that are thermally jacketed, which are in use in various industries. Both organic and inorganic chemical processors, pharmaceutical plants, and food processors just to mention but a few are some of the industries that utilize jacketed valves. Standard, hybrid and swaged systems are the three broad categories in which jackets are placed.
Among the most regularly utilized jacketing systems are the standard jacketing. These systems are preferred since uniform heat application is allowed for by covering pipes and valves from the flange. The core is the name used when referring to the body of the valve or pipe. The jacket is usually welded onto the flange. This means one should use oversize valves so that bolts can be accommodated.
It is not common for swaged jacketing to be put into use, save for unique instances. An example where swaged jackets are used is in instances where there is need for preventing cross contamination. One of the prerequisites for employing swaged systems of jacketing is when there is need to accommodate discontinuities in temperature at the flange. In most cases, when compared to standard jacketing, swaged jacketing are relatively cheaper. This is because in the case of swaged jacketing, small line flanges can employed to form what is referred to as capped or partial jacketing.
Like the name suggests, hybrid jacketing combines both standard and swaged jacketing systems. In addition to that, it also makes use of special and removal jacketing. Straight-line piping may be jacketed using swaged jacketing. On the other hand, fittings and valves may be jacketed using removable or standard jacketing so as to prevent temperature discontinuities at vital flow areas.
With technological improvements, one can jacket all types of valves without having any issue. Various fabric methods can be used for partial or full jacketing. In the method of standard fabrication, one can modify the valves for them to accommodate oversize flanges. Jacketing is done after the modification. One should maintain the interior tolerances of the valves after they have added jackets just as they were before they were jacketed.
There are a number of reasons that necessitate valve jacketing. The same reasons that necessitate jacketing also form the benefits of the process. To begin with, through jacketing, there is the capacity to keep processing temperatures within close tolerances. In addition, it helps achieve high heat transfer rates from heating mediums to processes. Lastly, jacketing makes it possible to undertake unit construction.
There are also a few disadvantages that are associated with jacketing. Some of them include relatively long component deliveries and presence of limited options of components that are jacketed. In addition to that, there are no fabrication standards in the industry. Major inconsistencies have been caused in components and products produced due to lack of industry-wide standards.
