What are the measures taken by the pipe compensator in the pipeline construction?

Release date:2017-12-06 Author:www.jsyyjx.com.cn Click:

The pipe compensator compensation pipe is the measure taken to prevent the pipe from being destroyed by the stress caused by the increase of temperature. It is mainly to use the elastic deformation of the pipe bending section or to set up the compensator on the pipe. The compensation ability of casing compensator, compact structure, small flow resistance of heating medium, but due to packing, need regular maintenance, can not withstand the lateral displacement, and makes the bearing withstand greater thrust, so much for the diameter greater than 200 mm on the straight section (called the expansion joint in water supply engineering).

The structure of the bellows compensator is simple, the compensation ability is small, and the pair configuration can compensate the heat elongation of the bend tube section. The spherical compensator can rotate at any angle along the axis. It usually compensates for the thermal elongation of the pipeline by two groups. It is easy to adapt to the spatial variation and the flow resistance of the heating medium is also small, but the manufacturing requirements are strict.

The elastic deformation of pipe bending pipes, such as L shape or Z shape and combination of them, is used to compensate for the thermal elongation of pipelines, which is called natural compensation, and the pipe segments that can be compensated are short. The natural square compensator is usually made of steel pipe by bending or welding. It is easy to manufacture and does not need regular maintenance. However, the heating medium has larger flow resistance and larger external dimensions. In fact, it also belongs to a natural compensator, which is equivalent to a combination of L or Z.

The pipeline compensator has a variety of forms, from the safety point of natural compensation security between large, followed by corrugated compensator and sleeve compensator, high spherical compensator and rotary compensator danger coefficient, often line the whole phenomenon of drop off phenomenon, usually because of shoddy work in pipeline construction, pipe hanger for no good quality control for pipe piers without reasonable arrangement good, relying solely on the compensator absorb various displacement of the pipeline is very late not scientific, just in line with the compensator to reduce the pipe hanger and fixed buttress the amount of effect and reasonable arrangement of pipeline space, save the cost of pipeline.

The general problems of the pipeline are only hope to fully assume the role compensator is very unreasonable, unreasonable layout of pipe hanger sliding bearing and fixed bearing Jerry, makes use of pipe compensator greatly exceeds the amount of the compensation design, caused by pull-out failure, even pipeline leakage and off the whole, generally spherical compensator and rotation compensator, compensator technology was not very dangerous, the general pipeline recommends the use of natural compensation, limited space area can be used for compensation.
