XTRU-THERM® GOLD

Product catalog summary

Introduction
The XTRU-THERM® GOLD is a preinsulated piping system designed for district heating and cooling, incorporating advanced corrosion protection technology from the oil and gas industry. This system features a multi-layered corrosion protection approach, ensuring durability and longevity.

Corrosion Protection
The system uses a shot-blasted steel service pipe to achieve a near-white surface, allowing for optimal adhesion of the corrosion protection coating. Three coating options are available: Epoxy, Urethane Elastomer, and Zinc, each suited for different environmental conditions and temperature requirements.

Insulation and Jacket
The XTRU-THERM® GOLD system utilizes high thermal efficiency polyurethane spray foam insulation, ensuring void-free application for maximum thermal efficiency. The insulation is protected by a seamless high-density polyethylene (HDPE) jacket, providing robust environmental protection.

System Features
The system is fully engineered with pre-fabricated components to reduce field costs and ensure a fully bonded system. This design prevents water ingress, which could degrade the insulation or service pipe.

Field Joint Closure Procedure
The field joint closure involves completing the service pipe joint, pouring foam insulation, wrapping a shrink sleeve around the joint area, and shrinking the sleeve using a propane torch.

Specifications
The piping system is designed in accordance with ASME B31.1 standards. The service pipe is made from ASTM A53 Gr. B carbon steel, with specific requirements for joint welding and coating application. Insulation thickness varies based on pipe size and application needs.

Accessories and Fittings
All fittings are factory prefabricated and preinsulated, with specific requirements for elbow and tee insulation jackets. Field joints are sealed with a heat shrinkable adhesive-backed sleeve.

Conclusion
The XTRU-THERM® GOLD system offers a comprehensive solution for district heating and cooling, combining advanced corrosion protection, efficient insulation, and robust environmental protection.
