SOCLEMA supplies the TRACEPAK range of tubes, designed for instrument pulse lines, sample transfer lines and process lines. These tubes enhance analysis and instrumentation systems in industrial applications: they protect against freezing, prevent the loss of chemical components when the temperature falls below the dew point, enable viscosity control...
The TRACEPAK range includes electrical trace lines (TPE) and steam trace lines (TPH and TPL) for frost protection and temperature maintenance, as well as pre-insulated lines (S-LINE) for steam supply and condensate return.
We offer solutions tailored to your specifications:
- Wide choice of materials and process tube dimensions
- Special treatments and coatings
- Lengths on request
- Sealing and electrical accessories
Pre-insulated tube with electrical tracing
TPE tubing is a pre-insulated tube bundle with self-regulating electrical tracing designed to provide protection against freezing, limit temperature variations or control viscosity. It's perfect for maintaining very long sections of impulse lines or piping at constant temperatures from end to end.
Depending on your application, you can choose your tube from the following options:
- One or two process tubes
- Process pipe in welded or seamless 316 stainless steel, in PFA in various diameters and thicknesses.
- High or low-temperature heating ribbon
- PVC or polyurethane sheathing
Pre-insulated tube with steam tracing
The TPL tube is a bundle of pre-insulated tubes with moderate tracing, the tracer tube being covered with insulation to reduce heat transfer. It is suitable for small-diameter process lines, such as those used for instrumentation, sampling or additive addition. It offers a more uniform tube temperature over longer lengths than strong steam tracers.
The TPH tube is a bundle of pre-insulated tubes with strong steam tracing, the process tubes being in contact with the tracer which thus maintains them at high temperatures. TPH is recommended for sample transfer lines, instrument pulse lines, additive additions and small-diameter process lines where higher temperature maintenance is required.
Depending on your application, you can choose your TPL or TPH tube from the following options:
- One or two process tubes
- Process pipe in welded or seamless 316 stainless steel, in PFA in various diameters and thicknesses.
- Traceur in welded or seamless 316 stainless steel, in copper, in various diameters and thicknesses.
- PVC or polyurethane sheathing
Coated and insulated tubing
J-Line tubing is used in applications requiring extra protection, but is neither insulated nor heated. It's ideal for pneumatic and hydraulic applications; the SV47 coating offers added protection against wear due to vibration.
S-LINE pre-insulated pipe is recommended for steam, condensate, liquid and gas lines from 0 to 25mm, where personnel protection and heat loss are important parameters. S-LINE is a less expensive alternative to on-site insulation and sealing of small-diameter lines.

Specific tubes for analysis
Sample transfer lines for process analyzers often require special tubes.
The starting point for the tubes offered by SOCLEMA is an ASTM-standard tube whose characteristics have been enhanced to increase resistance to corrosion, desiccation or adsorption and desorption. Using a tube that is not suitable for process conditions can lead to analysis system failure due to adsorption, contaminants, stress corrosion cracking or gas permeation during sample transfer. Reduced sample flow, excessively long response times or tube twisting are also problems that may be encountered, and which may be related to the choice of tube.
That's why we offer special tubes:
- Tubes in seamless drawn 316L stainless steel
- Chemically polished and cleaned 316L seamless tubes for reduced response times.
- Seamless drawn 316 L tubes, chemically polished, treated and coated with Silconert 2000, which are widely used for theanalysis of low-level sulfur compounds.
- Seamless drawn 316L tubes, chemically polished, treated and coated with Dursan to improve corrosion resistance.
- Seamless, electropolished 316L tubes offer excellent corrosion resistance.
- Seamless, electropolished and Silconert-coated 316L tubes are the best choice for corrosion resistance and sulfur applications. Electropolishing provides an ideal surface for the SilcoNert coating. The SilcoNert 2000 coating, covalently bonded to the silicone matrix, reduces surface tension and strongly limits adsorption/desorption of moisture and sulfur compounds. Well-suited to the measurement of sulfur compounds up to PPB. They offer the shortest response time of all our tubes.
Tests carried out on these tubes in GRTgaz's RICE laboratories have demonstrated the suitability of electropolis and Sulfinert-treated tubes for sulfur compounds. When flow rates are low and gas residence times are long, it has been shown that only the use of electropolis or electropolis/Silconert tubes provides representative results for the gas analyzed.
