Circumference is the distance around a circle (closed curve) which in this case would be the flange's circumference. A circumference is calculated by using the mathematical constant of Pi (3.143). It entails multiplying the outside diameter by 3.143.
Example: Diameter = 145mm
145 multiplied by 3.143 equals 455.735mm
You have to take the lead and packing out that is holding the flange in the next piece of pipe. If your flange is broke where the toilet bolts go, this is very common. There is a repair available for this. It consists of two curved pieces of metal that are about 1/3 of the circumference of the flange. They go under the flange and give you a new place to put the bolt. They are a lot easier to use than replacing the whole flange.
Probably the wrong size flange. Is the flange a toilet collar? If so the pipe is probably 4 inch.
The best method for installing a toilet flange on a cast iron pipe is to use a wax ring and secure the flange with screws. Make sure the flange is level and properly aligned with the pipe before tightening the screws.
No, it is not recommended to glue the toilet closet flange to the pipe. The flange should be secured to the floor using bolts or screws, and the toilet is then secured to the flange using wax rings or sealing gaskets. Gluing the flange to the pipe can make it difficult to remove or replace the toilet in the future.
What is actually broken the flnge ring rusted out and broke or the abs pipe? Abs pipe/flange broken: Use a ram bit to cut it out and install a new one. http://www.plumbingsupply.com/pvcsaver.html use a compression or expansion flange http://www.plumbingsupply.com/toiletflanges.html or just cut the pipe and put in a new one Flange ring rusted/broken: install a toilet flange repair ring or a spanner flange.
Usually toilet flange is glued down onto plastic drain pipe. There is a toilet flange that can be glued inside of plastic drain pipe also.
To replace a shower drain flange, you will need to remove the old flange by unscrewing it from the drain pipe. Then, clean the area around the drain pipe and install the new flange by screwing it into place. Make sure to seal the flange properly to prevent leaks.
depending on your type of flange and pipe and the damage of the flange, if you have a PVC flange with just the bolt slots busted then you can screw in new bolts to the floor below the flange and still use the flange but if its broken where the wax seal sits then if your flange is lower then the floor you can use a insert flange that fits inside your old toilet flange with thin walls to keep the pipe size maximum. To replace the entire flange can be a job especially if its in concrete or in a floor joist because most of the time you have no room and if its cast iron pipe it can be even more of headache but in order to replace the flange you need to cut it out to where you can reconnect the pipe and flange by using a fernco or a no hub band. Sometimes it is impossible to replace because the flange can be on all close fittings and you pretty much have to replace most of the plumbing drain pipe to replace it properly which is why you want to try repairing your toilet flange rather then replacing it .
The easiest solution would be to move the toilet so that it lines up with the waste pipe.
A pipe flange is used in the assembly of pipe to pipe or other things like valves, elbows etc. The flanges are bolted together, creating several lengths of pipe or other assemblies.
To install a blind flange, first ensure that the pipe ends are clean and free from debris. Align the blind flange with the pipe, ensuring the gasket is placed correctly between the flange and the pipe. Use appropriate bolts to secure the flange, tightening them in a crisscross pattern to ensure even pressure. Finally, check for any leaks by testing the system under pressure.
if it is a PVC flange glued on to the outside of 3" PVC pipe, there is a tool available that will cut it off and you can glue a new flange on the undamaged pipe. It's called a Flange-off. Available at Locke plumbing supply.
