Prefabricated insulated ductile iron Pipe

Prefabricated insulated ductile iron Pipe integrates ductile iron’s strength with pre-installed polyurethane insulation and anti-corrosion layers. It minimizes heat loss for hot water or district heating, withstanding -40℃ to 130℃ temperatures. The prefabricated design skips on-site insulation work, cutting installation time by 60%. Used in municipal heating, industrial fluid transport, it resists corrosion and has a 50+ year service life. Applied in Harbin’s cold-region projects, it ensures stable operation in harsh conditions.
