LANCING TUBES


Thermal/Oxygen Lancing Tubes


Blazing the Trail


Oxygen Lancing is a method where oxygen is used to cut through materials. This is done by feeding pressurised oxygen through a steel tube. The pressure of the oxygen causes the oxidised material to be blown away from the cut area. Temperatures of 2 000°176 to 4 000°176 is used to cut different types of materials in various industries.

A thermal or oxygen lance is a tool that is used to heat and melt iron with pressurised oxygen to create extremely high temperatures which is used for cutting steel.

Tubecon manufactures 3 different lancing tube types with the preferred type a "one to fit the other" flared lancing tube. The diameter of the tube at one end is increased so that another tube will fit into the same size. Flared lancing tubes does not require a ferule ensuring a safer system for the operator due to the possibility of a leak in the ferule system being eliminated. The leak occuring in the ferule system can cause burn back to the lance operator. On top of the aforementioned the flared lancing tube reduces the lancing period and saves production time.

Advantages of Tubecon's Flared (one-to-fit-the-other) Lancing Tubes:

  1. Safety:
    1. Tubecon lancing tube: one seal instead of two seals per joint. 50% less chance of leak.
    2. Joint side facing the operator has no seal therefore any flushes will be directed away from the operator towards the tap hole.
    3. The diameters of the tubes are closely controlled to ensure the tubes fit perfectly into one another, minimising the possibility of leaks occurring.

  2. Production
    1. In some cases ferules are welded onto the tubes, adding an extra process, taking production time. In this case flared lancing tubes safe time.
    2. Ferules tend to fall off causing longer production time.

  3. Various lengths can be supplied: longer lengths can increase worker safety.
