Popular Industrial Applications for Stainless Steel Pipe Hangers and ...

Usually do I use this type of pipe support due to the fact that it allows displacement in the horizontal plane,

Which would be the advantages and disadvantages of using this type of support? cause I have 2 cases:

Case 1
Pres: 300 PSI
Temp: 600 F
Pipe ASTM A-106GB

Case 2
Pres: 100 PSI
Temp: 70 F
Pipe ASTM A-53GB

Thnx for ur comments and best regards,

Given that you have a significant temperature change and thus movement, I would expect to see a shoe, and at 600F, some insulation too. Most engineers agree that a curved surface such a pipe or round bar is a poor pipe support due to the theoretical infinite stress at the contact point.

Some disagree however and require this kind of support !! 1. You need an insulation standoff.

2. Please get a better way to allow the 600 degree max temperature (600 - 70 nominal temp change): with this support the pipe skids and scrapes across the top of the horizontal support pipe. This very small rubbing point wears the two pipes out, gives a rust spot for corrosion to begin at the point where stress is the highest, which will eventually break through the pressure-carrying pipe.

3. The two side brackets are so far from the supported pipe that they will serve no value in restraining the supported pipe.

Get a pipe support catalog. They have many better examples.

4. The complex welded joint of the vertical pipe to the horizontal support pipe is easy to draw, but also difficult to actually cut and fabricate properly. I agree with the comments noted above, particularly those statements regarding the need for the pipe "shoe".

Additionally, I agree with dcastro about the "overkill" in the concrete design. The design seems too complex

A simple sonotube with the vertical member inset is usually adequate.

My thoughts:

1. Pipe shoe for 600 deg. line along with a good pipe stress engineer to determine the need for guides and anchors.
2. The specs I work with actually require ½” dia. smooth bar stock as the contact point on all supports.
3. The same specs do not allow pipe supports to be fabricated from pipe due to the chance of internal corrosion. Typically not caught until the support fails………
4. The foundation might be over designed, NOW. But in 5-10 years when it has several elec. conduits and other lines supported from it, it won’t be.
