Select clean copper pipes. Make sure there is no dust and
water inside. Use a pipe cutter when cutting the pipes, to
avoid a grind swarf generation. Do not use a saw or a grind
stone to cut pipes. Blow the inside of the pipes with nitrogen
or dry air, to remove any dust or foreign materials before
connecting pipes.
