Tube and Pipe Fabrication

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.

Setting standards for beverage production

February 28, 2002

By: ,

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.
