• Reduced costs, installation time and space-saving.
• Easy installation similar to an electrical cable.
• Available in very long lengths, thus reducing wastage of material, tube connections and the risk of leakages.
• Stranding technology ensures improved roundness, flexibility and equal bending radii in all directions.
• Extruded outer jacket provides reliable protection from mechanical wear, abrasion and corrosion.
• No maintenance needed.

Outer FR-PVC Jacket

We use UV resistant FR-PVC Jacket that protects the tubing against corrosive atmospheres, water, oils, acids, alkalies and most chemicals. Min./Max. allowable exposure temperature is -40~105°C, allowable surface temperature is 80°C. The material of outer jacket can be customized as per client’s requirements.

1. Heavy Steam Traced Bundle:

Steam tracer tube and process tube are in direct contact with each other. Heavy steam traced bundle normally used for high temperature steam which needs heat up as the requirement. This provide solution for pressure transmission and analyzer sample lines.

2. Light Steam Traced Bundle:

Steam tracer tube and process tube are separated from each other. Light steam traced bundle offers stable process temperature and freeze protection for water line, light oil, paraffin, oil of paraffin and other chemicals which are sensitive to temperature and chemicals. This provide the most ideal solution for freeze-protection, maintaining viscosity, etc.

Advantages

• As quick and easy to install as an energy cable, which reduces the installation cost.
• Available in very long lengths which reduce material costs due to fewer fittings and less material wastage.
• Less space requirements.
• Maintenance-free and well protected against mechanical damage, abrasion and corrosion.
• Approved to be used in hazardous areas.

Rating & Performance

Techwin International pre-insulated tubes and tube bundles maintains outer jacket temperature(personnel protection temperature) under 60°C and maintains inner process (fluid) temperature over 204°C. We use insulation material as fiber glass, aerogel that endures over 1200°F (649°C).

Insulation

We use non-hygroscopic fiber glass insulation in normal cases and where there are high process temperatures i.e. over 400°C, we use aerogel insulation. For more specific insulation details kindly contact our representatives.

Types of Electrical Heat Traced Tubing

1. Electrical traced tubing with constant wattage heating cable:-

Traceline with constant wattage heating cables is used for maintaining temperature upto 200°C and Max. exposure temperature upto 260°C. The key benefits are:-

• They are cut to length.
• Constant power output is available.
• No need for over sizing the CB as no inrush current at startup.

2. Electrical heat traced tubing with Self regulating heating cable:-

Traceline with self regulating heating cables is used for maintaining temperature upto 121°C and Max. Exposure temperature upto 250°C. The key benefits are:-

• They are cut to length.
• Variable output with change in the surrounding temperatures.
• Less chances of overheating.

More alternatives are available based upon the requirements.

Advantages

• Time- and cost-saving installation.
• As quick and easy to install as an energy cable, which reduces the installation cost.
• Available in very long lengths which reduce wastages due to fewer fittings and less material wastage.
• Reduced assembling steps.
• Less space requirements.
• Maintenance-free and well protected against mechanical damage, abrasion and corrosion.
• Approved to be used in hazardous areas.

Application
