Electrical Heat Traced Tubing

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

• Analyser Sampling LinesProcess Analysers – Emission Monitoring Systems – Gas Chromatographs
• Instrumentation Impulse LinesFlow Transmitters – Pressure Transmitters – Level Transmitters

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.

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.
