Outline 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.

In order to supply steam all round, a well laid out system is used. An inlet manifold which is enclosed on one end, distributes the vapor to the number of pipes that stem out from it. The outlet collects the condensate from the system to the collecting pipes. The heating area should be sufficient to ensure superb functioning. A suitable layout such as having the header on the upper part and the condensate collector at the bottom.

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 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.
