The Heritage-class cutter, also known as the Offshore Patrol Cutter and the Maritime Security Cutter, Medium, is a cutter class of the United States Coast Guard (USCG), developed as part of the Integrated Deepwater System Program and built by Eastern Shipbuilding [4] and Austal USA. [5] Construction of the first vessel in the class began in ...
Pipecutter Cutting copper pipe with a close quarters tubing cutter. A pipecutter is a type of tool used to cut pipe. Depending on the metal of the pipe, a pipecutter can often provide a faster, cleaner and more convenient way of cutting pipe than using a hacksaw. There are two types of pipe cutters.
Plasma CNC Pipe Cutting . Hot cutting refers to a process in which materials are cut using a thermal torch. One of the most common techniques is oxy-fuel gas cutting, which is used extensively for cutting carbon and low-alloy steels. However, its efficiency diminishes as the alloy content of the material increases, limiting its applicability ...
Stresses on the cutters are expected to be very severe. Structural analysis showed that some parts of the cutter could be expected to survive only 3 years. This was addressed in cutter 752 onwards, with the first two cutters receiving reinforcements. [50] WMSL-752, the Stratton, suffered corrosion and leaks within weeks of commissioning in 2012.
[4] During the early 20th century, before the development and availability of coated arc welding electrodes in the late 1920s that were capable of making sound welds in steel, oxy-acetylene welding was the only process capable of making welds of exceptionally high quality in virtually all metals in commercial use at the time.
Waterjet technology evolved in the post-war era as researchers around the world searched for new methods of efficient cutting systems. In 1956, Carl Johnson of Durox International in Luxembourg developed a method for cutting plastic shapes using a thin stream high-pressure water jet, but those materials, like paper, were soft materials.
