Outline Of Fabricated Steam Jackets

By Virginia Richardson


Indirect heating of substances in industries is widely embraced. Large cylindrical containers are surrounded with a casing to facilitate heat exchange between their walls. A circulating circuit with steam is fitted in the space of the two structures. This is capable of maintaining the desired temperature of the contents in the buffer. A suitable scheme is determined to construct the fabricated steam jackets.

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.

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 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.
