To ensure your piping system operates efficiently, it’s essential to carefully consider both the location and type of pipe supports.
Goto Zhiang to know more.
Plumbing codes mandate that all piping and its contents be properly supported to maintain alignment and prevent sagging. These codes also typically require hangers and strapping materials to be made from approved, non-corrosive materials that won’t cause galvanic action. Additionally, the materials must be strong enough to support the weight of the pipes and their contents. Approved materials like stainless steel and galvanized steel offer corrosion resistance, ensuring long-term durability.
Code also dictates the distance between supports, which varies based on the size and material of the pipe. Proper spacing ensures the piping system remains stable and prevents undue stress on the pipes.
Different pipe materials and sizes require specific types of pipe supports:
- PVC pipes and CPVC pipes: Lightweight and versatile, they are commonly supported with schedule 40 PVC pipe clamps or brackets.
- Copper pipes: These may require insulated pipe clamps to prevent noise and vibration.
- Steel pipes, such as carbon steel or galvanized steel: Heavier pipes demand heavy-duty pipe hangers or steel pipe brackets for secure support.
- Cast iron pipes: Often used for drain waste and vent (DWV) systems, they require strong, durable riser clamps or pipe straps.
For example, a one-inch copper or CPVC pipe will require a different hanger type and size than a comparable one-inch gas pipe due to differences in wall thickness, diameter, and weight.

After considering factors like material, size, load, and required support spacing, the final choice of pipe support may come down to personal preference.
Oatey Tip: The strength of your pipe supports is only as reliable as the material they’re anchored to, whether wood or concrete. Secure installation is critical for ensuring long-term durability.

I'm a structural engineer but need some advice. Ive done lots of pipe supports and racks with piping engineers before but in this case we dont have a pipe stress engineer involved. Yet.
We have a 36inch diameter pipe that's 20ft off the ground and about 90ft long before it elbows down into the ground. It has 6 pumps below it that feed it with wastewater effluent. The contractor says the pipe supports dont need any bracing because theres no lateral load in piping.
In my opinion it needs a piping engineer to determine if theres guide or anchor loads. At my past job if we didnt have a pipe stress analysis we assumed 30% pipe weight for friction load at guides and 35N/mm pipe dia for anchors plus seismic.
In your opinion is there obviously lateral load or does it need a piping engineer? What does B31 say about when you need a piping engineer to check it? Is there a minimum requirement? Thanks.
The piping load is the sum of multiple loads. You have the dead load of the piping, fluid, and whatever else is attached to the pipe supports.
You also have wind load. You also have earthquake load.
You also have the friction load from the pipe supports. These are the pipe anchor and guide forces caused by restrained dimensional changes caused by thermal expansion or contraction of piping under normal operating conditions (e.g., loads from a pipe stress analysis).
This pipe is large enough that you should have a pipe stress engineer evaluate it.
DCW815,
An experienced piping engineer, looking at the design, temperatures, other loads like wind and thermal expansion (when empty), snow, ice, seismic, people climbing all over it etc may simplify it down to your simple guide, which is better than the nothing that your construction contractor is telling you. Construction contractors in my experience never hang around long enough to see their constructions fail in operation and therefore their opinions are worth listening to, but ignoring 90% of the time.
You need to design the supports. To design the supports you need loads. Those loads come from the piping engineer / dept after some due analysis and design work.
Now you can forget about this and use figures that worked on the last job, but real life has a habit of not always being the same aa the last job. Might work this time, but if it doesn't and the structure bends / moves / collapses are you going to be sufficiently far away that they can't find you or your company or???
You clearly know what you should be doing so I would suggest that that is exactly what you do - the right thing.
There is very rarely no other loads than vertical weight. If not during operation then construction.
