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.
The casing can be fully continuous or discontinuous. They are identified differently on a plan since the nature of lines indicating them are different. Continuous means that all parts are covered including flanges, tees and welded parts while the opposite is the case for discontinuous. The type of insulation is indicated at the end of the lines to stipulate the vapor lines.
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.
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.
It is evident from the above that the process involving erection of such a system is detailed. There are regulations and specifications which should be followed per the company which in involved in the project. The layout, fitting and material used has to be suitable for proper service of the arrangement.
