Outline Of Fabricated Steam Jackets

By Virginia Richardson


Heating can be done directly or indirectly. Industries may involve the latter in their process. This is achieved by providing a casing on the cylinder containers with the content which need to be heated. The space between the walls of these vessels consists of coils which circulate the steam all around maintaining the temperature as required. The plan of fabricated steam jackets is as discussed below.

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.

Since there are two different categories of housing, the circuits layouts and connections vary. There are instances of having a jump over to connect a tapping point which is below to an adjacent section. They also carry the fumes and cooled water. The arrangement is such that is there are vertical pipes they should not exceed one meter. The layout should reduce the potential of condensate becoming semi solid.

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 material used to produce this kind of structure is the stainless steel to make the fittings and the piping. Due to the high temperatures involves at some of that industrial process, other material can be invented to fill the gap since they are capable of resisting corrosion. Specification by the company executing the work should be followed.

Pressure affects the operation capacity of that structure.Many regulations have been put in place to regulate it. Hydrostatic check must be carried out prior to allowing water vapor to flow. Visual inspection and nondestructive testing is done. This is a way of ensuring safety was considered during construction. It also allows operation to begin for the industrial process which was in consideration. This is only achieved by following the given codes.

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.
