자주 묻는 질문:
  • What are the main components of the polyurethane spraying prefabricated insulated steel pipe?
    The pipe consists of a steel working pipe, a polyurethane rigid foam insulation layer, and a polyethylene outer protective layer.
  • How does the polyurethane spraying process improve insulation performance?
    The polyurethane is sprayed in liquid form, foaming perpendicular to the pipe axis, which enhances adhesion and compressive strength.
  • What are the advantages of the circumferential winding process for the outer protective layer?
    Circumferential winding increases the elongation and tensile strength of the polyethylene layer, making it more durable and cost-effective.
  • What is the operating temperature range for these insulated pipes?
    The pipes can handle peak temperatures up to 140°C and continuous operation at 120°C.
