Name: S313 expansion bend
expansion joints Features:
    expansion joints, also known as expansion joints, expansion joints, compensators. Expansion joints within a certain range of axial stretching, can be overcome within a certain angle docking pipeline resulting in different axial offset, can greatly facilitate the installation and removal of the valve pipe, the pipe allows the amount of stretching can be free expansion, once the maximum amount of stretching over the limit on the play, to ensure the safe operation of pipelines. Mainly for the protection of the safe operation of pipelines, has the following effect: compensation to absorb pipe axial, lateral, angular thermal deformation; absorbing equipment vibration, reducing equipment vibration impact of the pipeline; absorb earthquake, subsidence of the pipeline deformation. Sleeve-type expansion joints for a variety of water supply and drainage, water towers, pumps, water meters, valve installation replace them provides a great convenience to the long-distance pipeline due to temperature expansion played a good role in the regulation.

Expansion joints Installation Notes:
    1. shall be installed between the maximum and the minimum length can be adjusted noted in the actual situation.
    2 installation, loosen the packing pressure plate bolts, adjust the length of installation, and ends with the tube (or valve, water meter) installed according to design requirements, and then check whether the packing put away, and finally the pressure on the pressure plate filler , with the diagonal method partial pressure not to tighten the bolts to make it play a role in Stop-leak.
    3 expansion joints installed after the valve.
    4 expansion joints at both ends must be set to buttress, and it does not bear the axial tension, necessary, to add anti-pull off.
