Insulators employed in the covering of processing components are referred to as jacket. There exist many components of such nature, including valves, pipes, accessories, pumps and filters. Jackets have one main function, that is, provision of insulation against heat loss. The item being jacketed is wrapped in the cover by using ropes to join the cover together. As long as the item is being used, the setup is retained intact.
There is a wide range of thermal-jacketed products that are used in various industries. Jacketed valves are used for both inorganic and organic chemical processors. Some of the industries that find use for jacketed products include petroleum plants, food processors, polymer producers, and pharmaceutical plants among others. There are three broad classifications for jackets, that is, hybrid, swaged, and standard systems.
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 is not in common use. It is only used in special cases. For instance, it finds use in cases where cross-contamination needs to be prevented. One condition of using swaged jacketing systems is that temperature discontinuities at the flanges must be able to be tolerated. Usually, swaged jacketing are cheaper in comparison to standard jacketing. The reason for this is that small in-line flanges can be used with swaged jacketing to form what is called partial or capped 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 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.
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.
A few shortcomings are also involved in jacketing as well. They include availability of a limited selection of jacketed components and relatively long deliveries for the components. Secondly, there is a lack of industry-wide fabrication standards. This has led to major inconsistencies in products and components produced.
