Insulators used to cover processing components are referred to as jackets. There is a lot of variance in these components. Some of the processing components include accessories, pipes, valves, pumps, and filters. The main role played by these jackets is provision of thermal insulation. Hooks are joined together firmly by use of ropes to wrap the cover around the item. This outfit is retained if the item is being used.
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.
Swaged jacketing systems are rarely used, only finding use in special situations. For example, cases that require prevention of cross-contamination are where they find use. Among the conditions for one to use swaged jacketing systems is when temperature discontinuities at the flanges have to be tolerated. This is because small in-line flanges could be used alongside swaged jacketing to form what is referred to as capped or partial jacketing.
Just as indicated by the name, hybrid jacketing combines swaged and standard jacketing systems. Furthermore, it additionally utilizes removal and special jacketing. Swaged jacketing may be used in straight line piping. On the flip side, standard or removable jacketing may be used on valves and fittings in order to protect vital flow areas from temperature discontinuities.
With modern technology, all kinds of valves can be jacketed without any problem. The jacketing can be done fully or partially using various fabricating techniques. In standard fabrication technique, valves are modified so that they can accept oversize flanges. The body of the valve is usually extended as necessary to meet certain standards. After modification, the jacket is added. Interior tolerances of the valve must remain the same after jacketing as in an unjacketed valve.
The reasons for placing jackets around valves are plenty. It is these reasons that also comprise of the advantages of jacketing. Firstly, maintaining temperatures of processing in close tolerances is made possible when jacketing is done. The second advantage is that high heat transfer rates are attained from the medium of heating to the process. Finally, jacketing assists in enabling one to do unit construction.
On top of it all, there are a number of demerits associated with jacketing. To begin with, there is limited jacketed components selection and significantly untimely component deliveries. Furthermore, there are no fabrication standards maintained in this industry. This has resulted in significant discrepancies in the components made and products.
