SOCLEMA offers traced tubes specially adapted to industrial analysis for sample transfer lines. To select the most suitable tube, it is necessary to carefully examine the process conditions.
When using stainless steel trace tubes, we are often confronted withadsorption and desorption phenomena. These phenomena delay the detection of variations in trace quantities of certain components (notably moisture and the sulfur compounds H2S and SO2). The structure of stainless steels is such that certain compounds can be trapped in the tube's "crevices". When the tube reaches saturation, the levels remain stable as long as the chemical composition remains unchanged, and the temperature and pressure remain constant. Any change in composition, temperature or pressure modifies the rate of adsorption or release of compounds, creating false peaks when the analysis is read. These phenomena, sometimes referred to as the " memory effect ", are responsible for inconsistent measurements. This problem can be solved by using electropolished and/or Sulfinert-coated tubing.
Silconert 2000 is a patented, inert barrier that protects against chemical substances. It consists of amorphous silicone interdiffused on chemically polished 316L stainless steel tubing. The treated surface is then passivated with covalent bonds of hydrocarbon molecules. There are different trade names for the same treatment: Silconert®, Sulfinert® or Siltek®.
To meet customer demand and ensure rapid delivery, SOCLEMA now stocks seamless 316/316L stainless steel tube, 1/4″ and 1/8″ O.D x 0.035″ thick passivated and chemically polished with Silcotek Silconert™ 2000 treatment in 6-meter bars.
The tube can be cut to any length.
