With technology advancement, pipe cutting has incorporated complex techniques that require immense skill to get the job done. The most common pipe cutting methods involve the use of either explosives or chemicals. One has to be equally experienced in the pipe cutting to handle the procedure using these delicate tools rightly. For any pipe cutting method to be effective, it must be economical, repeatable, flexible, environmentally friendly and utmost safe. The pipe cutting methods discussed below are either already available in the construction industry or are slowly being developed by contractors.
Chemical cutter is one of the most commonly used methods for pipe cutting. The chosen chemical eats through the targeted steel wall producing neat cuts with no debris left over. Chemical cutters are mostly preferred where the operating time is minimal, and the budget costs are minimal. Also, they can be used to cut pipes during abandonment and plug operations. The target area must reach specific measures before it is passed as effective and desirable. Many pipe cutting minneapolis mn contractors prefer to first view the site area before settling for chemical cutters. Conditions such as heavy walled pipe, scale, plastic liner, higher alloy, increased depth, paraffin deposits, imperfections in the pipe and incorrect gun sizing could all slow down the chemical pipe cutting process.
Radial Explosive Cutters
It is designed to cut through coiled tubing, casing and drill pipe during operations. Radial explosive cutters apply the severance action of explosive charge to slice through pipes. Explosive cutters provide a quick and effective solution for pipe cutting. Usually, these cutters contain a high precision pressed chemical that reacts together to explode and cut the target area.
Radial Cutting Torch
It is a cutting device that is used to sever tubing, coiled pipes and drill pipes without necessarily using any explosives or environmentally unsafe materials. This element makes it one of the safest options currently in the market. Incorporating advanced technology, the nozzle sprays a mixture of various powered metals that react together to produce a highly energized plasma that cuts virtually into any pipe. Due to its inert nature when not in use, the radial pipe cutting torch can easily be transported from one construction site to another, quickly and effectively.
Abrasive cutters have been reintroduced into the market after in-depth study and experiments. Abrasive cutters make the best technique having the potential to rapidly sleeve through almost any type of pipe located at any depth. These types of cutter use a particulate of sand, calcium carbonate and glass beads. The particulate is exerted through a rotating nozzle, and the abrasion erodes the steel. Its nature can cut even through a heavy piping material as long as the cutter is kept at the same place during the entire pipe cutting operation. They have proven to be one of the fastest pipe cutting tools.
Mechanical pipe cutting is mainly utilized on jointed or coiled tubing when required to be split. They are generally slower compared to the chemical or explosive cutters. For that reason, they are better used on softer alloy piped that have thinner walls. Pipes with thick alloy material pose a challenge for mechanical cutters to slice through although it could be an option.
