Help! What is the standard source that specifies measures to reduce the friction coefficient for sliding pipe supports in large-diameter pipes with DN≥800?
Thread Content
For large-diameter pipes with DN≥800, measures should be taken to reduce the friction coefficient for sliding pipe supports. I would like to know in which codes or standards such requirements are specified
It might be some design institute’s own regulation; the only publicly available standard is SHT 3073-2016, and I don’t seem to have come across this term anywhere.
Section 3.1.3 of HG/T21629
I learned it; I really hadn’t noticed this before! By the way, I have a question: if the vertical load is 20 kN and the friction coefficient between steel surfaces is 0.3, then the horizontal force should be 6 kN. But with the addition of PTFE pads, it is possible to apply a horizontal force of 2 kN to the structure – is that correct? Is this approach of using additional PTFE shims to reduce horizontal forces on the structure commonly used in design?
That’s what it means; using low-friction setups is also quite common in engineering.
