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.

On a drawing it is possible to identify the type of housing, because the lines are drawn differently for each category. Continuous and discontinuous are bars are the general envelope. The former encloses every part of that cylinder while the latter leaves out welded parts, tees and elbows. Insulation sort is given in order to know the number of vapor lines.

Vapor is circulated using coils in the space between the walls and the envelope. The area is calculated to ensure proper heating of the cylinder. The inlet pipe should be elevated above the one that is collecting the condensate. It is also fitted with a trap to force the cooled water fumes out to the outlet. This outline enables to have outstanding performance of the whole setup.

Different line designs are available. This makes all the connections to be different. A tapping link is created for two adjacent sections. The link transports the cooled fluid and also the effective one. When there are vertical pipes, the height should not exceed one meter upwards. The arrangement should ensure that the fluid cooling rate is minimized as much as possible.

Welded portions should not be hidden. They must be exposed to and accessible for the purpose of testing. Visual and non-destructive inspection is necessary. Longitudinal welded joints should not cross each other. They are scattered all over the surface. Valves should be able to handle the fluctuating flow rate at the header and exit. Standard specifications should be adhered to completely.

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 of these works is necessary to ensure it is safe to use the system. Hydrostatic testing is done for the housing before applying the water fumes in it. Inspection by observation is require to make sure the piping standards have been met. This should not be destructive. This process is important as it gives the go ahead to implement the invention.

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.
