Plasma Cutting
In opposite of abrasive cutting, also well known as the cold cutting technology where no heat is allowed, there are specific environments in which the application of heat is not an issue. In these situations plasma cutting could be the technology to consider. For inside or outside cutting of a pipe the same manipulators to rotate the plasma cutter can be applied as for rotating the abrasive cutter. This means the cutting process is remotely and thereby safe controlled. This way of cutting is very cost effective and also in this case, there are practical no diameter limitations.
