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.
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.
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.
