PVC tube have many practical uses from drainage to transferring your drinking water. Generally, PVC pipes are solid and durable, but they deserve to only manage 28 pounds before they start to bend. Whether you have a load-deflecting or self-deflecting PVC pipe, follow along as we explore how you can calculate the maximum load it have the right to handle.


When I first got introduced to PVC pipe, it was due to the fact that friends of mine do faux swords for live-action duty playing gear. Nowadays, I understand PVC pipeline is a staple of most plumbing endeavors, and also to a point, can likewise be used in various other projects. PVC is a pretty sturdy material, but every product will have its limits. So, what’s the attend to PVC pipe?

PVC pipeline is remarkably solid when it comes to its tensile strength, however how lot it can handle is walk to count on the size and thickness that the piping. Many PVC pipes will certainly not have the ability to hold more than 28 pounds before they begin to bend. Part pipes will also start to bend under their own weight if they are too long.

You are watching: How much weight will pvc pipe support

A good rule of thumb is that you should never try to use PVC pipe to hold huge quantities of weight, particularly if friend don’t want them to it is in reinforced.

A quick Guide On how Much Weight her Pipe can Hold

Physics way that your pipe will have the ability to hold less weight the longer and thinner it is. There are two main species of PVC pipe the you can get: self-deflecting and also load-deflecting. When we room going to talk around the fill that a pipe can bear, we room going to emphasis on load-deflecting pipes.

Self-deflecting pipes are normally going to start to bend underneath their very own weight. How much lock bend deserve to vary greatly, but the truth is that the fact that they bend under their own weight suggests that lock shouldn’t be supplied for load-bearing under any type of circumstances.

The Max weight You can Use top top Load-Deflecting PVC Pipes

The chart listed below shows the stats ~ above load-deflecting pipes, and also how much weight they deserve to handle on prior to they start to bend. If your pipe’s horizontal size is over 4 feet in length, climate you shouldn’t shot to usage it come bear loads, simply because longer pipe can end up being self-deflecting pipes.

Horizontal expectancy Length (ft.)1/2″ Size3/4″ Size1″ Size1-1/4″ Size1-1/2″ Size2″ Size
1′ 18 lb. 28 lb. 40 lb. 50 lb. 58 lb. 70 lb.
2′ 5 lb. 10 lb. 24 lb. 35 lb. 45 lb. 55 lb.
3′ 3 lb. 6 lb. 11 lb. 20 lb. 30 lb. 35 lb.
4′ 2 lb. 3 lb. 6 lb. 11 lb. 23 lb. 28 lb.

How space These Load-Bearing Statistics Measured?

The means that this stats are measured the end is simple. Scientists put the pipe in between two chairs (or various other things that host it up). If it’s a self-deflecting PVC pipe, lock measured just how much of a bend the pipe had actually in the center. If that was load deflecting PVC pipe in between the chairs, they would add weight until they i found it the PVC pipeline bending in the middle. That would certainly turn into the max load they deserve to bear.

If you desire to calculate the vertical load of any of this load-bearing statistics, main point the maximum pack by 2.8. The vertical drop help reinforce the toughness of PVC immensely.

Will You be able to Support that Weight ~ above The end Of The PVC Pipe?

Here’s something that you must be mindful of through PVC piping and also the maximum load it can bear: the weight said is an alleged to be measured in ~ the center of a pipe. If you put that same amount of weight on the end of your pipe, you will not only have actually the pipe bend, but also probably break.

This is because of the physics behind load-bearing. Once scientists calculation load-bearing, they space relying top top the tensile strength of PVC holding up both political parties evenly. If you have actually a fill on one end of the pipe, there’s just tensile stamin supporting one side of the load. This puts a higher strain ~ above the entire system.

Is It smart To usage PVC Pipe because that Load-Bearing?

Yes and no. PVC pipe on its own have the right to be pretty fragile and also frail, despite its sturdy appearance. While it have the right to be used to bear a tiny load reliably in many cases, the truth is that it’s not an ideal material for this. If girlfriend don’t have anything else on hand, you have the right to usually use PVC as long as it’s reinforced and engineered through a solid support system.

How come Reinforce PVC pipeline For much better Load-Bearing

If you desire to usage your PVC pipe for load-bearing purposes, over there are ways to carry out it. These tips listed below can assist make sure your pipeline won’t bend or rest while it’s keeping loads up:

Use it for vertical load-bearing.Horizontal load-bearing method that you’re working against gravity a lot more. That’s why horizontal load-bearing maximums are so much lower than upright ones.If you must go horizontal, add supports.Having support beams that are vertically propping increase the PVC pipe will sell reinforcements and greatly improve the all at once sturdiness of your piping.Heavy pack bearing shouldn’t it is in attempted v PVC pipe.Do you want to try to placed 350 pounds on a PVC pipe? While having reinforcements close to the center of your pipe can help, us strongly imply that you examine out metal alternatives instead. Incredibly heavy loads should no be attempted through PVC.Use Kevlar support ropes whenever you notice bending.Sometimes it’s no so lot a matter of gift able come bear extra weight, but rather, a must keep the pipe from bending under its very own weight. Kevlar assistance ropes can help hang your PVC indigenous the ceiling without bends.

When should You Worry?

Let’s say the there is miscellaneous you’re do the efforts to develop (or have actually built) and also you’re spring at exactly how much weight her pipe is bearing. You began to an alert a tiny sag. Sometimes, the doesn’t have to be a huge issue. As soon as you notice a droop that’s end an inch in depth, or you an alert that the PVC pipe is beginning to warp, that’s once you should gain concerned.

Warping can happen for a wide selection of different reasons, but it often method that the PVC pipeline you’re managing is undergoing structural stress. With self-deflecting pipes, that’s normal. Yet if your pipe is brief enough to it is in load-deflecting, it’s a problem. Including some support can assist reduce the stress. However, if it’s a system that has actually lots the risk connected (i.e., channeling heavy steam to a place) you might want to speak to a pro.

Is it safe to usage PVC for water lines?

It actually relies on the temperature the the water. If you want to usage PVC to command cold water (or lukewarm water) from one place to another, it’s great. PVC is strong enough to have the ability to be used in numerous plumbing situations, i m sorry is why most sink P-traps room made native the stuff.

However, if you want to channel warm water through the piping, PVC is turn off the table. Water that’s also hot deserve to actually malfunction the chemicals the make PVC strong. This, in turn, can cause the pips to break down, get brittle, and also eventually spring a leak. Come prevent troubles later on, use steel for hot water plumbing.

Does Gorilla Glue job-related on PVC pipes?

Yes, however it really counts on which form of Gorilla adhesive you desire to get. Not every one of the glues do by the Gorilla Glue agency work an extremely well. If you desire to use it top top PVC, the best option is Gorilla adhesive PVC Cement. This has a specially-designed formula that naturally bonds come the polymers in PVC.

If friend don’t have actually Gorilla glue Cement top top hand, climate you deserve to use any type of other form of PVC-specific cement glue to fasten her PVC piping. Through that said, we completely get the brand loyalty.

Why is PVC poor to use?

A many studies room now saying that PVC piping isn’t for sure to use, at the very least for those through chemical sensitivities. PVC contains chemicals choose phthalates, cadmium, and also organotins that have the right to leech right into the water and air of her home. If the all at once consensus is the PVC’s affect on your home’s chemical levels is not an extremely powerful, it’s tho something to save in mind.
