What is the difference between a Cast Hoop and Triple Flange hoop?
If you can get to the 6 inch cast iron, you could use a rubber coupler between the cast and the flange. If it is in the concrete, put a piece of 4 inch PVC inside the 6 inch and lead it in like you would a regular cast joint. Leave the 4 inch above the floor and slide the flange over it, screw it down and cut the 4 inch flush with the flange. They make just the flange that will slide over the pipe.
Normally whether use the forged flange or cast flange depends on the design code, material, pressure, temperature, stress strength and medium of the piping system. It has been decided since the beginning of the design. If forged flange is chosen, it is very dangerous for you to use cast flange due to its much lower strength and other mechanical&chemical performance. If cast flange is chosen, it is not sensible to change it to forged flange because of the high cost.

I removed the broken flange by perforating the lead filling between the drain pipe and the flange - i.e., drilling holes every 1/4-1/2 inch or so with a regular drill and then sawing through the filling with a power saber saw. Then pried the flange off with a pry bar. Wasn't as bad as I expected. - Dan
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.
You can buy the new cast iron flanges, with the expandable O rings that push into the pipe or you'll have to do the old style or pouring lead onto a cast iron flange. The latter option should only be done by professionals.
about a 75 # weight difference between both sides.
Floor flange, cast iron ,brass with floor flange bolts (brass) wax gasket and make sure the line is vented
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 .
Cast iron, often break where the bolts sit. There is a repair kit available. It is two flat curved pieces of metal about 3/4 wide and one third the circumference of the flange. It slides under the flange and pulls against the remaining cast iron. There is a complete ring available that is just a flat ring with 6 ears sticking out around the edge that should clear the cast iron. Screw it down to the floor and install the toilet. The full ring can be used with any flange.
Production method is different. Cold rolling method and different.
The difference is that the cast play in the film (TV program, documentary, etc.) and the crew are the people behind the scenes who help the cast get ready and other tasks.
aren't they the same thing
