Compensator
Compensator also called expansion joints, expansion joints, the Compensator. Compensator in a certain range can be axial expansion, but also to a certain point of connection between different in overcoming the pipeline axial offset arise, can greatly facilitate the valve pipe installation and removal, pipe allows expansion of free expansion, once crossed its maximum expansion of the role of the limit to ensure the safe operation of the pipeline. Compensator in a certain range can be axial expansion, but also to a certain point of connection between different in overcoming the pipeline axial offset arise, can greatly facilitate the valve pipe installation and removal, pipe allows expansion of free expansion, once crossed its maximum expansion to limit the amount of, ensure the safe operation of the pipeline. Main to protect piping security operation, has the following effect: compensation absorption pipeline axial, lateral and angular thermal deformation; vibration absorbing devices, reduce equipment vibration effect of the pipeline; absorb earthquake, land subsidence on the deformation of the pipe.
1. the products to various drainage pipes, water tanks, pumps, water meters, valves installation Mtbr provides great convenience, to long distance pipeline expansion due to temperature differences has played a very good effect.
2. the product is divided into cast iron pipes (HT), galvanized (DX) and steel (SF). Working pressure-PN6, PN10, PN16 three.
3. the installation must release the pressure plate bolts, the La-installation length, and then tighten using a diagonal method, do not press too, such as overhead, both ends must install the appropriate retention bracket.
4. flange connection using GB4216.3-4126.5 standards.
5. If the use of other sizes can be manufactured.
Compensator connections:
Flange connections, welded two, buried compensator (non-trench, located well installation) generally use welding.
Compensator installation notes:
1, the Compensator should be checked before installing their models, specifications and pipeline configuration, you must meet the design requirements.
2, with internal sleeve compensator should note that internal sleeve of direction consistent with the medium flow direction, hinge-type compensator hinge rotation planes should be consistent with the displacement of rotation plane.
3, need for "cold tight" compensator, the pre-distortion of auxiliary components should be installed in the pipeline before demolition.
4. strictly forbidden to use compensator deformation method to adjust the pipeline installation variance, so as not to affect the proper functioning of the Compensator, reduce the service life and increase piping, equipment, support widget loads.
5, the installation process, do not allow welding slag splash to wave the surface of the shell does not allow wave shell and other mechanical damage.
6. piping to be installed as soon as possible after the removal of wave compensator for installation of auxiliary position of yellow component and fasteners, and as designed is supported to provide location so that the tube Department in environmental conditions have adequate compensation.
7, compensator all active components shall not be an external component card dead or limit the scope of their activities, should ensure that the activities part of the normal operation.
8, hydrostatic test, coping with compensator pipe end in time fixed pipe support for strengthening the pipeline without moving or turning. On the gas medium and its connecting pipe compensator, attention should be paid to whether water filling need temporary support. Hydraulic test water washing of 96 chloride ion content not exceeding 25PPM.
Compensator:
Due to the Compensator has a good overall performance, so it is widely used in chemical industry, construction, water supply, drainage, oil, and heavy industry, refrigeration, sanitary, plumbing, fire, electric power and other infrastructure projects.
