Pre Insulated Tubing


Techwin International pre-insulated tubings are designed specifically for smaller steam, condensate, liquid and gas transport lines where the low temperature drops are due to low heat losses. To avoid heat loss, the tubes are pre insulated with thermal insulation which is made of several layers and protected by outer jacket material in accordance with client requirements. This offers an inexpensive alternative to field insulation and weatherproofing of small diameter lines.

These pre insulated tubings are available in long lengths in coil form and also available in straight lengths as per project requirement.

  • 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).


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.
