STEAM TRACED TUBING

Two different types of Steam Traced Tubing Bundles

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.

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.
