Tube Selection for Analyzer Sample Systems

Selecting the right process tube for use in analyzer sample transport systems requires consideration of process and application conditions. There are a wide variety of metallic and non-metallic tubes available: welded and seamless 316 series stainless steel and more exotic alloys are also used.

Common non-metallic tube materials are PFA, PFE, and PTFE fluoropolymers polyethylene and Halar (ECTFE). Some bundles may also contain coaxial tubing (tube-in-tube) or unheated tubes for calibration gas and blowback lines.

O’Brien TrueTube provides a wide variety of in-house services that dramatically improve the performance of industrial tubing including electropolishing and chemical passivation as well as thermocouple cleaning and cleaning for oxygen service. We combine these with Silcotek's SilcoNert™ 2000 fused silica coating for the ultimate in sample transport consistency and speed.

Improper tube selection may lead to a failed analyzer systems caused by adsorption, contaminants in the tube, corrosion stress cracking or gas permeation. Restricted sample flow, long sample lag times, and kinking are also problems often related to tube selection.
