Supply Hengtai S313 expansion joints; necessary, to add anti-pull-off sleeve sealer

Expansion joints Features: expansion joints, also known as expansion joints, expansion joints, compensators. Expansion joints within a certain range of axial stretch, but also to overcome the pipe butt and produce different axial offset within a certain angle, can greatly facilitate the installation and removal of the pipeline valve in the pipeline to allow the amount of stretching can be free stretching, once past its maximum expansion volume to play limit, to ensure the safe operation of the pipeline. Mainly for the protection of the safe operation of the pipeline, it has the following effects: Compensation absorption pipe axial, lateral and angular thermal deformation; deformation of the pipeline to absorb earthquake, subsidence; absorbing equipment vibration, reducing equipment vibration impact of the pipeline. Sleeve-type expansion joints of various water supply and drainage, water towers, pumps, water meters, installation of removable valve provides a great convenience, for long-distance pipeline stretching due to temperature regulation played a very good role. Expansion joints Installation Notes: 1. The installation should be between the maximum and minimum length, can be noted in the actual situation adjustment. 2. When installation, loosen the bolts packing pressure plate, adjusting the installation length and ends of the tube (or valve, water) is installed according to design requirements, and then check the packing is properly seated, and finally the pressure on the packing pressure plate, with a diagonal method partial pressure not to tighten the bolts to stanch role to play. 3. expansion joints installed after the check valve. The expansion joints must be set buttress ends, which itself does not bear axial tension, necessary, to add anti-pull-off.
