Selection of welded pipe supports and clip-type pipe supports
Thread Content
In HGT21629-2021 \"Standard Drawings for Pipe Racks\", there are welded pipe supports J1 and clip-type pipe supports J2 for insulated pipes. In what scenarios are they used respectively? After checking the usage conditions, it seems they should be interchangeable. I usually choose the clip-type pipe support J2 for applications with high temperatures and large displacements.
The welded pipe support J1 is suitable for applications with low temperatures and minimal displacement changes, as its robust structure enables it to withstand large loads. The pipe clamp type pipe support J2 is more suitable for applications with high temperatures and large displacements, as it can accommodate the thermal expansion and movement of pipes, and its installation is relatively simple. Although they can be used interchangeably under certain conditions, it is still necessary to choose the appropriate one based on the specific operating conditions to ensure safety and stability. For pipes under high temperatures and with large displacements, the pipe clamp type support J2 is more suitable. .
J1 is used for carbon steel pipes, and J2 is used for stainless steel pipes.
