What are the requirements for the installation of luoying non-metallic expansion joints
Non-metallic expansion joints can compensate for multiple displacement directions. Various forms, large compensation, good life, can compensate or remove installation errors, low stiffness, small elastic reaction force, high use temperature range, not easy to corrosive performance is good, can ground isolation vibration and reduce noise. The good comprehensive performance of non-metallic expansion joints makes them commonly used in many engineering areas. The working pressure is not high ventilation, dust and smoke exhaust and air conditioning insulation pipeline and equipment usually use the pumper.
What are the installation requirements of non-metallic expansion joints? The following, for you to speak in detail:
1 . Compensator in the installation before the first check its model, specifications and pipeline configuration, need to meet the design requirements.
2 . During installation, do not allow the welding slag splash to the surface of the wave shell, do not allow the wave shell by other mechanical damage.
3 . Compensator all movable elements can not be external components jammed or limit its range of activities, should determine the normal action of each active part.
4 . Need to be "cold tight" compensator, pre-deformation of the auxiliary components used should be installed in the pipeline before removal.
5 . After the end of the hydraulic test, the water in the wave shell should be drained as soon as possible, and not slow to blow dry the inner surface of the wave shell.
