How much clearance space is required below any sprinkler head?
The 18-inch applies only to areas that have sprinklers installed. Picture a horizontal plane parallel to the ceiling that is 18 inches below the sprinkler heads. Nothing should be in that area between the bottom of the sprinkler heads and the imaginary horizontal plane parallel to the ceiling that is 18 inches below.
How much clearance is needed for a fire sprinkler?
As a general rule, NFPA 13, Installation of Sprinkler Systems, requires 18 inches of clearance, but makes the following modifications: For standard pendent and upright spray (SSP/SSU) sprinklers, the 18- inch dimension is not intended to limit the height of shelving or storage along a wall as illustrated below.

Can anything be touching sprinkler pipe?
“The Joint Commission and CMS have zero tolerance that prohibits anything being supported by the sprinkler piping system, including incidental contact,” the commission notes.
Can you hang something from a fire sprinkler?
It’s against NFPA code: Hanging items from sprinklers or pipe heads is a violation of two National Fire Protection Association codes – and codes are in place for a reason.
Can EMT touch sprinklers?
If either your conduit or the sprinkler pipe is PVC, then you are okay with them touching. If they are both metal, then you could end up with dielectric corrosion, so separation must be maintained.
How much weight can a sprinkler pipe hold?
Chapter 9 of NFPA 13, Standard for the Installation of Sprinkler Systems, provides requirements for hanging and bracing. The building structure integrity must be capable of supporting the weight of the water filled pipe plus 250 pounds, with some exceptions.

What is the strongest steel tubing?
See all 10 photos Round tubing is the strongest by weight, but square and rectangular tubing is also very helpful in fabrication, especially for framerails and some brackets like motor mounts or rock slider tie-ins. Round tube is about the strongest shape by weight.
Is round or square tubing stronger?
The answer is round tube has a higher resistance to both flex and torsional twisting than square for a given weight.
Which is stronger round or square aluminum tubing?
When it comes to aluminum tube, shape is also a determining factor in overall strength. For example, round tube is stronger than square tube of an equal length and weight, In addition, round tube has a higher resistance to both flex and torsional twisting than square tube for a given weight.
