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.

The hot water fumes are circulated by a system of pipes all-round the enveloped structure. The inlet vapor supply is enclosed at one side to act as a trapper. It enables to push the condensate toward the collection manifold. The area of exchange should be sufficient to obtain desired results. The header has to be at a higher elevation from the collector pipe. This is to allow self-draining of that fluid.

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.

For the purpose of testing, the welded parts has to be visible and accessible. The valves incorporated must be able to handle the flow rate at the inlet which may be high and the rate at the outlet which may be less. The specifications of that company must be followed to the latter. Keeping all fragment in the right state is necessary. The longitudinal welds should be staggered and prevent cross interactions.

The standard materials suitable for use steel which may be carbonated. It may not be suitable to use when harsh conditions present themselves like high temperature. Others are manufactured to take care of the deficit that would arise. Other suitable substances can be used to achieve the same goal. In selecting the most convenient, the quality of the project is taken into account.

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 end, it is obvious that the work involved forms a major task. Selecting components to be used and the material they will be made of should follow some specific procedure acceptable. Each and every segment of that design is important to ensure that the housing serves the life it is required of it. Layout should be as expected.
