Is the installation of pipe hangers compliant with standards?
Thread Content
As shown in the figure, the pipe is a high-pressure steam pipe, and the fixing plate of the spring hanger is directly welded to the pipe. Personally, I think this approach shouldn’t be feasible. I wonder if there are any issues with installing it in this way? Are there any specifications that provide clear guidance on this?
I’ve never seen anyone do this; it shouldn’t be possible!
This won’t work, unless the construction party provides absolutely reliable calculation documents. Otherwise, it should be selected in accordance with the support and hanger manual, using that type of crossbeam
This might not be a problem with the construction contractor; it’s a design issue. Of course, if it’s the general contractor, then it can be attributed to the construction contractor
I remember from looking at catalogs that this kind of thing usually uses a clamping card
Is there still a spring support in the lower horizontal section?
High-pressure steam pipes, no!
Is there a problem? Is it the high-pressure steam pipeline that does not allow welding of fixing plates? Is it the wrong choice of supports and hangers in the first place? I hope some expert will step forward to explain it
Clamps with insulation blocks should be used to prevent the transfer of high temperatures and to slow down the corrosion of the hangers. With this direct welding method, heat is transferred to the suspension rod; due to the presence of heat, water, and air, rusting occurs very quickly.
