Radial conduit cutting system and method
View Patent ↗What is presented is a combustible pellet for creating heated gas. The combustible pellet can be inserted into a cutting apparatus or a high power igniter or both. The combustible pellet is compacted to be resistant to mechanical damage, resistant to unintentional ignition, and free from a loose powdered form of combustible material when ignited in the cutting apparatus or the high power igniter. In certain instances, the combustible pellet is compacted to between 90 percent and 99 percent of its theoretical density. The combustible pellet may be capable of being transported separate from the cutting apparatus or the high power igniter or both. The combustible pellet may also be capable of being stored separate from the cutting apparatus or the high power igniter or both. The combustible pellet may comprise a circular cross-section and tubular length. The combustible pellet may comprise an axial hole.
1. A method of safely transporting a cutting apparatus, the method comprising:
conveying a combustible pellet to a job site, the combustible pellet compacted to be resistant to mechanical damage and the combustible pellet resistant to unintentional ignition;
conveying the cutting apparatus to the job site separately from the combustible pellet; and
assembling the cutting apparatus at the job site by inserting at least one combustible pellet into the cutting apparatus without any loose powdered forms of combustible material.
2. The method of safely transporting a cutting apparatus of claim 1 further comprising:
determining the number of combustible pellets to be inserted into the cutting apparatus based on the characteristics of the cutting apparatus; and
inserting at least one combustible pellet into the cutting apparatus based on the determination of the characteristics of the cutting apparatus.
3. The method of safely transporting a cutting apparatus of claim 1 further comprising:
determining the number of combustible pellets to be inserted into the cutting apparatus based on the characteristics of the conduit to be cut; and
inserting at least one combustible pellet into the cutting apparatus based on the determination of the characteristics of the conduit to be cut.
4. The method of safely transporting a cutting apparatus of claim 1 wherein the combustible pellet is compacted to between 90 percent and 99 percent of its theoretical density.
5. The method of safely transporting a cutting apparatus of claim 1 wherein the combustible pellet is made from thermite, oxidizers, carbon-based fuels, Polytetrafluoroethylene, Fluoropolymer elastomer, other polymers, or some combination thereof.
