A column radiator is used to describe a typical cast iron radiator. The term describes the vertical columns that make up the radiator. The radiators can also be made out of steal and not cast iron. The steal is welded together.
There are several companies who produce or sell cast iron models of radiators. For example, try the company 'Cast Rads' of the 'Radiator Center' for these radiators.
1/2" - 2" depending on demand
The boiler has a circulation pump that circulate the water
If the copper is big enough, you can treat it as if it were cast and use packing and sealant. If the diameters are too different, you can use a rubber coupling to connect the two.
Buy a shorter one. Welding Cast Iron is a pain and to do what you want would require cutting out a section and re-welding the whole thing. Baseboard hydraunic heaters can be shortened but cast is a no go.
On a 2000 Saturn you should probably replace whatever part is leaking rather than gum it up with a sealant. If you must use a sealant you would remove the pressurized radiator cap.(This cap may not be on the radiator on all models. It may be located on a plastic surge tank located separate from the radiator.) Once the engine has reached full operating temperature add the sealant in to the rest of the coolant. Top off the coolant and replace cap. Run engine or drive for 10 minutes. Then shut the car off and allow to cool completely. NOTE:Radiator sealants will not stop leaks of rotating shaft seals(water pumps). Additionally, modern engines such as the ones used in Saturns have tight engine clearances and small water passages through aluminum parts. Sealants are a safe bet to use on the over-sized cast iron engines of days of yore, but a modern engine is isn't made for that kind of gunk surging through its veins.
Depending on condition, between $50-$200 seems to be going rate.
Answer replacing cast iron with PVCThere is a rubber sleeve available that goes in the cast iron and then the PVC slides into it. Use a rubber outside sleeve with two hose clamps. You can also replace the rusted section with PVC and them "lead" them with the packing and a paste sealant that is made for this.
Yes, but be sure to install a small automatic air vent in the small tapping on the top at either end.
The weight of a home radiator can vary depending on its size and material. On average, a typical cast iron home radiator can weigh around 100-200 pounds. However, modern aluminum radiators are much lighter and can weigh only around 20-50 pounds.
Cast iron is fabricated in blast furnaces where iron ore is reduced by coke to cast iron, according to Wikipedia.
