1. When selecting the pipeline support and hanger, the appropriate support and hanger should be selected according to the load size and direction of the support point, the displacement of the pipeline, whether the working temperature is insulated and cold, and the material of the pipeline:

2. When designing pipe supports and hangers, standard pipe clamps, pipe supports and pipe hangers should be used as much as possible;

3. Welded pipe supports and pipe hangers save steel than clamp-type pipe supports and pipe hangers, and are simple to manufacture and construction methods. Therefore, except for the following cases, welded pipe clamps and pipe hangers should be used as much as possible;

1) Pipes made of carbon steel with the medium temperature in the pipe equal to or greater than 400 degrees;

2) low temperature pipeline;

3) Alloy steel pipes;

4) Pipes that need to be dismantled and repaired frequently during production;
