Arshan heat pipe network project
2023-12-02

Arshan is one of the highest latitude areas in my country.

 The heating project requires extremely harsh changes in the supply and return water temperature in the cold areas. The rigid polyurethane sprayed polyethylene wrapped prefabricated direct buried insulation pipe using Donghong's spray winding process effectively completes the transportation task while being cost-effective, economical, energy-saving, and green and environmentally friendly. It demonstrates the excellent transportation capacity of Donghong's new generation of spray-wound insulation pipes in the field of heat.
