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 two most common methods of applying zinc metal to steel handrail tubing are batch hot-dip galvanizing and inline, continuous galvanizing. The batch hot-dip method provides a coating thickness approximately 3 times that of the inline method, and a coating that lasts approximately 3 times as long. However, for indoor applications that do not require more than 500 PSI of bond strength, inline galvanized tube can be cost-effective.

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.
