Tubing vs. Piping
Many facilities depend on fluid delivery sent through piping systems. Unfortunately, cutting, welding and threading hard pipe is not a quick process. It is slow and labor intensive. A better alternative may be stainless steel tubing. Stainless steel tubing, instead of hard pipe, can greatly simplify installation and plant maintenance.
Many hard piping systems contain hard 90-degree turns (elbows) which create pressure drop. By contrast, stainless steel tubing is bendable to precise radii. Instead of 90-degree elbows, gradual sweeps are created, which minimize pressure drop. With stainless steel tubing, technicians can be trained to manage the bending and assembly.
Threaded pipe fittings are more likely to leak, especially in systems with vibration or thermal expansion and contraction. A combination of tube bending and automated orbital welding can greatly reduce the number of potential leak points.
For mechanical connections the Swagelok Tube Fitting is a solution that will not back off during thermal cycling or high vibrations. The fitting is able to resist vibration using the live-loaded action of the front and back ferrule. The colleting of the back ferrule also isolates, dampens and protects the stress riser in the tubing, preventing weakness in the wall. Swagelok Tube Fittings are capable of being made and remade with speed and ease. As a result, stainless steel tubing systems can pay for themselves many times over.
Stainless steel tubing systems eliminate the need to flush the system before installation as they do not produce the filings or chips that are many times found in piping systems. These filings and chips are created when pipe threads are cut into the pipe and can cause clogs, affecting the system performance.
