Design Of Fabricated Steam Jackets

By Virginia Richardson


Industries uses major of their containers to heat substances to be cylindrical in shape. To maintain its content with the temperature they need, these buffers are fitted with a casing which is capable of circulating the steam all around the space between the jacket and the vessel. This is a form of indirect heating of the substances. The design of fabricated steam jackets takes into account the following considerations.

Casing for the cylinder can be continuous or discontinuous. The type of lines to be constructed are marked properly in the drawing given for execution of the work, each with a different pattern. The solid lines indicate whole enclosure of these containers. Broken rule imply that welded parts, tees and elbow have been left out. The insulation to be used is also indicated as it assists to know the number of vapor bars present.

In order to supply steam all round, a well laid out system is used. An inlet manifold which is enclosed on one end, distributes the vapor to the number of pipes that stem out from it. The outlet collects the condensate from the system to the collecting pipes. The heating area should be sufficient to ensure superb functioning. A suitable layout such as having the header on the upper part and the condensate collector at the bottom.

There are different kinds of enveloping, therefore layout and connections vary. It is required to join two points, a tapping position and another adjacent section. These are capable of transferring evaporated fumes and the cooled one to the next division. Vertical pipes present should not be more than a meter high. Generally, the outline should minimize congealing as much as possible.

When considering this sort of a project, the specification of that company has to be adhered to. Any section that is welded has to be easy accessed for the purpose of testing after fitting the system together. The control valves should be able to handle the inlet capacities when it is at the maximum and also during the low flow rate at the exit.

The standard material used for construction is standard steel. At times, the processes in that industries may involve corrosive temperature. Better materials are thus invented to replace those incapable of delivering. When deciding which is applicable, several aspects should be considered by those involved in that project. Other substances can be used for the same purpose.

Testing procedure cannot be overlooked. Hydrostatic testing is carried out on the housing. Nondestructive and visual inspections are done to ensure that the standards are met for operational purposes. This is carried out before vapor is allowed in this system. It is a means of ensuring that safety is adhered to and operations can commence.

To conclude, the process involved in ensuring that this system works is wanting and must be taken seriously. Each stage is crucial and should be well interpreted. Specifications of those administering or executing the project has to be followed. The selection of materials, connections and layout should ensure proper functioning of the housing and longer service.
