What is an Oxygen Lance? (with picture) - wiseGEEK

An oxygen lance is a device used to melt or cut steel too thick to be cut with a conventional oxy-acetylene torch using a long alloy steel tube or pipe to feed oxygen under pressure to a preheated area. The oxygen lance achieves this cutting action by causing an oxidation and melting reaction of a preheated area of the material to be cut by directing the jet of oxygen onto it.cold drawn steel oxygen lance pipeA wide variety of oxygen lance pipe options are available to you, such as erw, hot rolled, and cold drawn.
