Canadian Pipe

A thermic lance is a pipe or tube filled with wire rods. The lance is connected to a source of oxygen and ignited. As the thermic lance is consumed, heat is generated enabling the bars to melt a variety of materials.

We recommend that the user/operator of the thermic lance be well protected and exercise proper safety precautions. We suggest the operator wear heat protective gloves and a welder’s mask (preferably with the 4 1/2” x 5 1/2” No. 5 or No. 6 shade) and a hard hat.

A minimum of equipment is required. An oxygen hose and fittings and a supply of pressure oxygen, and a regulator are necessary. Generally a bar will be consumed within 4 to 5 minutes. Oxygen consumption in a standard 3/8 x 10’6” thermic lance is 10 cubic feet per minute.

Most Effective Thermic Lance:
Numerous burn tests have been conducted with similar ambient temperatures and with an exact 75 PSI being maintained. The Push Fit proved to be the most economical thermic lance, with a burning time for a 3/8” x 10’6” lance of 5 minutes.

Canadian Pipe Supply also carries a complete line of holders for use with the thermic lance.

Thermic Lance bars are available with plain ends, threaded one end, threaded both ends, threaded and coupled and push fit quick couple.
