Product Introduction

This is an efficient insulation pipeline designed for underground heat transfer. Its core is made by advanced "spraying and winding" process: directly spray the working steel pipe to form a dense rigid polyurethane foam insulation layer to achieve ultra-low heat loss; Wrap it with a high-density polyethylene outer protective tube to form a sturdy anti-corrosion shell. This "pipe in pipe" structure combines excellent insulation, waterproof sealing, and strong mechanical protection, making it a "golden combination". The overall performance of the product is excellent, which can significantly reduce heating energy consumption, is safe and stable, and has a service life of over 30 years. It is an ideal choice for prefabricated buried pipe networks such as urban centralized heating and cooling.
