Because the reliability and accuracy of analyses are essential, transporting the sample from the sampling point to the analyzer is a key stage that requires special attention.
\n\n\n\nTraced-tube solutions provide the right response to industrial constraints (flow, temperature, corrosion). This article explains how these tubes contribute to operational performance - and how, at SOCLEMA, we implement them for you.
\n\n\n\n\n\n\n\nThe tube is the physical interface between the sample (gas or liquid) and the analysis device. It must therefore guarantee :
\n\n\n\nOur range of tubes is designed for transporting samples to analysis systems.
\n\n\n\nFrom the sampling point to the heart of the analysis, the tube must be optimally sized, insulated and, if necessary, traced.
\n\n\n\nAt SOCLEMA, we often use traced tubes to perform these functions.
\n\n\n\n\n\n\n\nTraced tubes help maintain temperature and protect against freezing, thus avoiding condensation, loss of fluidity or any undesirable phase change.
\n\n\n\nTwo types of tracing are recommended:
\n\n\n\nGenerally speaking, the choice of steam or electric tracing is dictated by unit preference. In addition to the availability of steam or electricity in a unit, zone classification and the properties of the process to be winterized or maintained at a specific temperature must also be taken into account.

It's important to choose the right tube for your specific application.
\n\n\n\nIncorrect tube selection can lead to analysis system failure due toadsorption, contaminants, stress corrosion cracking or gas permeation during sample transfer.
\n\n\n\nReduced sample flow, long response timesand tube twisting are other problems often encountered in connection with tube selection.
\n\n\n\nWe offer metallic and non-metallic tubes for a wide range of applications: stainless steel, copper, specific alloys, PFA, PTFE...
\n\n\n\nAt SOCLEMA, we help you select:
\n\n\n\nSurface finish plays a role in the adsorption and desorption problems encountered in analysis.
\n\n\n\nThis is just one of the parameters involved in tube selection. However, like the other parameters, it can improve or limit the lasting accuracy of the entire analysis system.

Internal coatings can be applied to the inner surface of the analysis tube, greatly reducing response time. Pressure and temperature characteristics are generally identical, and interactions between the metal surface and specific compounds are eliminated.
\n\n\n\nFor harsh environments (corrosive atmosphere, condensation, dust, chemicals), specific surface treatments and coatings are often essential. These include chemical polishing, electro-polishing, passivation, anti-corrosion coatings, etc.
\n\n\n\nWe can integrate these treatments and coatings into the tubes. These finishes improve service life, safety and reliability.
