The characteristics of the bypass pressure balance corrugated compensator
Bypass pressure balance corrugated compensator (TPP) has the ability to absorb internal pressure force, has a good guidance, product small rigidity, small overall dimensions, etc.
Bypass the connecting way of pressure balance corrugated compensator
1, 2, to take over the connection flange connection
Bypass pressure balance of corrugated compensator installation instructions
1. The product before the installation, should check, the make and model of the compensator specifications meet the design requirements of the piping.
2. Between two fixed bracket can only install a bypass pressure balance compensator.
3. The strength of the fixed bracket must comply with the design requirements, to ensure that the compensator is not subject to damage; Guide bracket must have enough guidance or influence line displacement.
4. Corrugated compensator are generally do not absorb torque, so do not allow the compensator is torque when installation.
5. The need for "cold" compensator, the prestressing of auxiliary components, should be removed after the compensator predeformation.
6. After the completion of the piping installation shall be immediately removed compensator is used as the install auxiliary positioning and ? transport protection
7. In addition to the design requirements of pretension pressure or "cold" predeformation, corrugated pipe deformation method is strictly prohibited to adjust the pipeline installation deviation, so as not to affect the normal function of the compensator, otherwise it will reduce its service life and increase the piping, equipment and load of support components.
8. The pipe to neutral, in the absence of other methods to ensure, straight cut length after laying pipe can be used again to ensure that the installation of expansion joint method.
9. Insulation should be done outside the compensator cases, shall not adopt any chlorine heat preservation material.
10. The installation process do not allow the slag splash to the corrugated pipe surface or other mechanical damage to bellows.
11. Compensator is allowed no more than 1.5 times the nominal pressure of the system pressure test.
12. The compensator used in the gas medium and its connected pipes, do water pressure test, whether you need to consider when water filling of the compensator to take over the adding temporary support to bearing.
13. Hydrostatic test water must be clean, no corrosion, and control the content of chloride ion in water less than 25 PPM.
14. For products of steam pipe network, water pressure test the back end of the corrugated pipe in the water.
15. Equipped with compensator in the operation of the pipeline, valve opening and closing to gradually, in order to avoid rapid changes in temperature and pressure in the pipeline, causes the damage of stents or compensator.
16. With a hydrophobic device before the second run, in the steam piping network of a compensator of hydrophobic device should be open, row net the condensed water inside the sleeve, and then the hydrophobic device tighten.
