Install the hard tube line, please pay attention as following:

1、The suitable tube length and outside diameter. The higher velocity of flow may loss more energy.

2、It should be avoided pull tight between two fixed points connection. There should be a part of loose turn. As shown, in order to facilitate handling, serious strees should be avoided due to the expansion and contraction principle. The structural drawing as shown below,


3、The radius of steel pipe elbow should be as big as possible; the smallest radius of elbow should be about 2.5 times as big as outside diameter of steel tubes. The end of tube should be kept the straight tube part and its distance should be two times higher than pipe connection nut. The structural drawing as shown below,


4、Main invalidation pattern of the hard tube is fatigue invalidation caused by mechanical vibrations.Therefore the pipeline is longer, pipe clip for bolster should be used. It could reduce vibrations and noise. When connect bending tube, should use pipe clip for bolster to fix in both ends of straight tube of U shape; when connecting bending tube ,pipe clip for bolster should be used to.Spacing for pipe clip reference as following,


5、Do not use too many 90 degree curving tubes to evade obstacle. When fluid passes through a 90 degree, the pressure dropping will be more than to pass through two 45 degree curving tubes .The structural drawing as shown below,


6、When arranging the pipeline, the part which must be maintained frequently should be far from the pipeline.

7、The pipeline arrangement should be in order and neat so that it is easy for breakdown search, the maintenance and the service. As shown below,
