Urban heating pipe network

Heating polyurethane insulated steel pipe insulation pipe is widely used in liquid and gas transportation pipe network, chemical pipeline insulation engineering petroleum, chemical, centralized heating and heating network, central air conditioning ventilation pipe, municipal engineering, etc. The high temperature prefabricated direct buried thermal insulation pipe is a direct buried prefabricated thermal insulation pipe with good thermal insulation performance, safe and reliable, and low engineering cost. It effectively solves the problem of insulation, sliding lubrication and waterproofing of the pipe end of the prefabricated direct buried thermal insulation pipe for 130°C-600°C high temperature heat transfer in urban central heating.
