Wirepak® Thermic Lance Tube


For Steel and Concrete Cutting

Wirepak® Thermic Lance



Wirepak Oxygen Lance tube provides a simple and cheap method of achieving extremely high flame temperatures capable of melting even refractory material, ingots, moulds etc. The basic reaction which takes place between iron and oxygen is :

3Fe+20 2 =FE3O4+265 kcal.

The energy is released as heat at a temperature above 4 000° C.

Wirepak Thermic Lance tube is available in the following sizes: 


Nominal Bore (Metric) Nominal Bore Imperial Mass / Meter Kg/M Number of 2.8mm Wires Standard Length in Metres
10mm 3/8 1.44 13 2.0; 3.0 and 4.0
