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.
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.
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 flange threaded in center used for weld or different types of threaded 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.
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.
Square a flange? Lol there is many hundereds of types of flanges so I don't know what flange you are talking about. If its a toilet flange and you want the toilet bolt holes equal to the wall (if its PVC or abs) just use a big pair of pliers or pipe wrench to turn it soon after you glue your flange.
A flange spreader is a device that uses a ratchet, leverage and fulcrum points to spread a bolt together connection. Usually welded pipe to flange, then a seal or gasket, and then another flange, and then welded or threaded pipe carries on. A flange spreader is used to spread the flanges apart to change a gasket or put in a spec blind to blank either side of the connection.
