ABSTRACT:
A gas and oxygen lance includes a top support member with first and second connector assemblies connected together with a quick release arrangement. The connector assemblies both include plates with aligned openings which transmit oxygen, gas, and water from the top support to the nozzle by means of oxygen, gas, and water pipes. The lance includes a sleeve assembly connected to one of the connector assemblies which is readily replaceable and which are connected in relative sealing and sliding relation to the oxygen and gas pipes. O-ring seals are provided to prevent leakage and a venting system safeguards the assembly in the event of leakage.
