Vertical supporting of pipes
Vertical supporting of pipes
(OP)
Can we use same support spacing in vertical pipes as that of horizontal pipes? General guide line for horizantal lines is 2 rest suppots and a guide (on rack)so is there any guide line there for vertical spacing? Any thumb rule for vertical pipes supported from vertical vessel? as in vertical pipes guide is only guide as in horizantal pipes guide is guide + rest.
Thanks

Example:
If horizontal spacing for Supports for a 4" line = 20' (+/-)
then
the vertical spacing of Guides for a 4" line would = 40' (+/-)
Wind and other factors must also be considered.

RE: Vertical supporting of pipes
The guide spacing for vertical should be normally smaller then for the horizontal ones, due stability reasons.
The support point in the vertical should be placed prefereable above the Gravity center point, due the pendulum effect, it is not obligatory but is good unless you have thermal problems. In equipments the support point shoud be near the nozzle.
I don't know any thumb rule for the spacing. For the small diameters may be a half of the horizontal, for the biggers may be less. Say something like 3m - 2"ND, 4m -3"ND, 6m - 4"ND, 6m - 6" ND.
Anyway the best idea is analyse the project conditions and prepare a table for your team. Take with winds and seismic, mainly as the previous coleagues have said.
