How to fix the cutting of DN400 at a high position
Thread Content
How should the DN400 pipe on the ductwork be secured to prevent it from falling on one side? Should temporary supports be added? What type would be suitable?
To put it clearly, just pipe cutting?
There is a place for hanging it; it’s better to use a hand chain hoist； There is a space for support below; it’s better to use wooden blocks or steel sections as padding. Insufficient information; I don’t know.
The pipeline crosses the middle of the two pipe supports as the cutting point. The cut pipelines in the top pipe gallery are lifted away using a crane, while those in the middle layer of the pipe gallery are moved out of the gallery using winches before being lifted down with a crane.
Please describe the problem in detail; it would be helpful to have photos or sketches so that everyone can discuss it more effectively. More participation is welcome
