Cold metal cutting saws are designed to rapidly cut lengths or pieces of zinc-coated, steel sheet metal without heating up either the blade or the material.
• Always use the insulation that is properly sized for the pipe it is to cover. Do not stretch it over the pipe. • Do not crowd insulation-covered pipes. Space pipes far enough apart to allow for the free circulation of air. Air movement is an extra safeguard against surface condensation of cold pipes, especially under hot, humid conditions.
Hot tapping is an alternative procedure that makes a new pipeline connection while the pipeline remains in service, flowing natural gas under pressure. The hot tap procedure involves attaching a branch connection and valve on the outside of an operating pipeline, and then cutting out the pipe-line wall within the branch and removing the wall
Cold Cutting . A cold cutting procedure is used to cut and/or bevel (prep) pipe work without generating spark, flame or excessive heat. The fact that the procedure generates no flame and/or spark to complete the cut and weld preparation makes it the safest and most cost effective way for abandonment, additions and replacement of pipe work.

Pipe cold cutting is a process to cut pipes without heating up the pipe material. Where high temperature or big heat are not desirable, Pipe Cold Cutting machines are used. Especially at offshore, high pressure boilers and pipeline construction this cutting methode is very popular.
Nov 21, 2017 · A significant advantage of the cold cutting process over torch cutting is the prevention of a HAZ (Heat Affected Zone). A HAZ is created when extreme temperature such as those produced by plasma or acetylene torches, is applied to a pipe. This changes the molecular structure of metal itself and often alters its properties to detrimental effect.
reason, every pipe suffers a certain elongation during the bending process, but it is possible to approximately determine the corresponding cutting length with the help of mathematical calculation. The stress-free layer is positioned even further inside, it is the layer, which shows no longitudinal stress at all after ductile forming.
