Temporary repairs are usually made by securing some type of patch over the damaged section of pipe.  The material used for the patch depends upon the type of piping that is being repaired.  A good general rule to go by is to make the temporary patch from the same type of material that is used for the flange gaskets in the system.  Back up the patch with a piece of sheet metal, and secure the sheet metal to the pipe with bolted metal clamps or similar devices.  A sealing compound may be applied between the patch and the pipe to help seal the patched area.  For low pressure salt water piping, a satisfactory patch can be made from red lead putty wrapped with canvas and served with marlin or friction tape. Small holes in some piping may be temporarily repaired by drilling and threading and inserting a screw.
