What are Broco rods made of?
Broco Underwater Ultrathermic Cutting Rods consist of an electrical insulating tape wrapped copper flashed steel alloy tube containing alloy wires arranged circularly around the inner perimeter. Classification of the Substance or Mixture: Inert, non-hazardous as supplied.
What is Broco cutting?
Broco® Exothermic Cutting Systems are the professional’s first choice for cutting, gouging and piercing. Utilizing only oxygen, Broco rods quickly cut or melt cast iron, steel, stainless steel, concrete, granite, nickel, titanium, aluminum and exotic metals.
How does Broco cutting work?
The Broco Ultrathermic (Exothermic) Cutting Rod produces a temperature in excess of 10,000° F. These rods cut through marine growth, rust, and mill scale, eliminating the need for pre-cleaning and helping to lower operating costs and reducing bottom time.
How are exothermic burning bars and cutting rods ignited?
The exothermic reaction (Oxidation) occurs when the tip of the rod is heated to its kindling temperature (2800 f) and pure oxygen is introduced through the bar. The only gas required for this cutting operation is pure oxygen. Cutting steel with an exothermic torch requires no preheat or cleaning.
Will an oxy acetylene torch work underwater?
The combustible gas, which might be hydrogen or acetylene, depending on the application, can be combined with oxygen gas (the oxidizer) to produce an underwater flame at the tip of the torch. The gas must be supplied at a high enough pressure to overcome the pressure exerted by the water.
How hot is a thermal lance?
7000°F to 8000°F
A thermal lance, also known as a burning bar or thermic lance, is an industrial tool that uses the oxidization of iron to generate very high temperatures (7000°F to 8000°F, or 3,871°C to 4,426°C) for cutting through just about anything, including rock.
Can you torch underwater?
The oxidizer is the oxygen in the surrounding atmosphere. These two ingredients can sustain a candle flame. In the case of an underwater torch, both the combustible substance and the oxidizer must be supplied by hoses leading down to the torch, since no free oxygen is available underwater.
What is an exothermic torch?
An exothermic torch works by feeding oxygen through an exothermic carbon steel cutting rod that is charged by the 12-volt battery. The cutting rod will continue to burn as long as the oxygen is supplied. This apparatus uses standard industrial grade oxygen and fittings.
How hot is an exothermic torch?
When used in cutting, the exothermic process uses oxygen as an exciter, thus the steel rod becomes the fuel. As long as the oxygen flow is maintained through the torch and rod, the rod will continue to burn and consume at a temperature between 8,000-10,000°F.
What element is used in a thermic lance that makes it so hot?
Powdered magnesium also ignites fairly easily in oxygen and then burns with an extremely hot flame which provides temperatures well above the melting points and even the boiling points of many metals.
Can a thermal lance cut concrete?
It is able to cut any type of material: metallic (steel, stainless steel, high nickel alloys, copper and bronze alloys, aluminum, manganese and shielding steels and any type of alloy) or non-metallic ones (ceramic, concrete, refractory bricks etc.); in short, this thermal lance can cut or pierce any known material.
