Thermic Lance Pipe Daiwa Lance is an essential tool designed for a variety of industrial applications. This lance features an outer diameter of 26.1mm and a wall thickness of 0.8mm, with a length of 1000mm, making it ideal for cutting steel bracings on offshore structures, pipelines, and concrete caissons. Its effectiveness extends to removing jetty and pier foundations, as well as cutting through vessels, propellers, and other marine salvage materials.

Constructed from carbon steel, the Thermic Lance Pipe offers durability and reliability. Each lance is fitted with high visibility polyolefin tubing for improved safety during operations. It requires standard industry equipment, including an underwater cutting torch, a multistage high flow oxygen regulator, and a DC welding machine. The lance operates effectively with minimal power requirements, igniting at approximately 4000°C to melt most materials easily.

Product description:

Thermal Cutting Lance has many uses in industry for both dry and wet applications alike, such as cutting steel bracings on offshore structures, pipelines, removing jetty and pier foundations, cutting through concrete caissons, vessels, propellers and other types of marine salvage.

Each lance is constructed from a copper coated steel tube 9.5mm (3/8") OD x 450mm (18") long. The tubes are all fitted with high visibility polyolefin tubing for easy use and improved safety. All underwater Cutting Lances are packed to prevent oil and grease contamination.

The process simply requires an industry standard underwater cutting torch connected to a multistage high flow oxygen regulator, a DC welding machine and a safety isolation switch. Should you prefer to cut with the power on, the lance should require no more than ~150 amps at the tip.

However, the lance will also burn with no electrical power, once ignited, as long as the oxygen flow is maintained. The lance burns at approximately 4000°C a temperature that will melt most materials with ease.

The principle of operation, having ignited the arc is to allow oxygen to flow down through the centre of the lance. This creates and maintains an exothermic reaction, which will continue to burn, with or without the power, until the oxygen flow is stopped.
