The tube and pipe fabrication technology area covers sawing (band, circular, and friction) and other cutting processes, such as abrasive, flame, laser, oxyfuel, plasma, and waterjet. It also discusses forming processes, including bending and end forming. Finally, it includes a handful of miscellaneous processes, such as trimming, beveling, finning, grooving, threading, and spinning.

The pitfalls of building a beverage processing facility can be many. Poor welds involving tubing, fittings, and valves provide opportunities for bacteria to grow, creating health concerns and the potential for ruined product. Orbital welding -- which provides higher-quality, consistent welds compared to manual welding -- helps to reduce these concerns.

The rotary cutting process rotates a tube or pipe and cuts it with a rotating blade. The blades are beveled to various angles and produce a chamfered end on the workpiece. Selecting the right bevel angle is the key in getting an optimal combination of end finish and production rate. Proper alignment and clearance, the use of a lubricant, frequent inspections, and proper sharpening are the keys to long blade life.
