Separate rusted galvanized pipe by heating with a torch, applying a plumber's candle, tapping with a hammer and turning with pipe wrenches. If necessary, place a length of pipe over the handle of the pipe wrench to increase torque.Know More
Use a propane torch to heat the joint. The expansion and contraction helps to break through the rust.
While the joint is still hot enough to melt wax, rub a plumber's candle around the intersection of the two pipes. As the joint cools, it draws the wax into the joint, providing lubrication to reduce friction from the rust.
Hit the joint with a hammer to help loosen the rust.
Attach a pipe wrench to each of the two pipes that have rusted together. Hold the pipe stationary, and turn the fitting counterclockwise to loosen it. If the pipe refuses to budge, use a larger pipe wrench or apply more leverage by placing a length of pipe over the handle of the wrench. If the joint does not loosen, heat the joint and apply more wax. Continue the process until the joint breaks free.
Pipe spools are sections of pipe that have been put together with fittings off-site to meet the needs of a construction project, according to the International Journal of Architecture, Engineering and Construction. Pipe spools increase the speed of construction.Full Answer >
PVC glue can be used on CPVC pipe but doing so will often result in leaks and degradation of the seal on the joints, so it is not recommended. PVC and CPVC are made up of similar chemical elements, but they are not interchangeable.Full Answer >
