Polyethylene insulation spiral steel pipe refers to after the insulation process processing, in different working environments and external media roles to ensure that the working steel pipe internal temperature and surface temperature meet or reach the required steel pipe. Polyethylene insulation spiral steel pipe refers to after the insulation process processing, in different working environments and external media roles to ensure that the working steel pipe internal temperature and surface temperature meet or reach the required steel pipe.

Thermal insulation pipes are widely used for liquid, gas conveying pipe network, chemical pipe insulation engineering oil, chemical, centralized heating heating network, central air conditioning ventilation pipe, municipal engineering and so on. High temperature prefabricated direct buried insulation tube is a good insulation performance, plus a safe and reliable, engineering low cost direct buried insulation tube.
