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.
To solder copper pipe, polish the joining surfaces, apply the flux, heat the joint and apply solder. Each joint requires a few minutes to complete, but the time for the overall project depends on its complexity.Full Answer >
To glue ABS pipe fittings, apply glue designated for use with this specific product to the pipe and fitting. Push the fittings together using a twisting motion to ensure even distribution of the glue. Hold the joint together for a few seconds to ensure it does not pull apart during the setting of the fast-drying glue. No primer is required when gluing ABS pipe fittings.Full Answer >
The average wall thickness of a copper water pipe used above ground in residential buildings is 0.076 inches. However, the wall thickness of a copper water pipe varies considerably based on the type of function performed by a water pipe and the area where it is installed.Full Answer >
Some commonly used copper pipe sizes are 1/4 inch to 8 inch tubes that come in 20 foot lengths, 10 inch pipes that come in 18 foot lengths and 12 inch pipes that come in 12 foot lengths. These are straight pipes.Full Answer >
