Product Q&A
Q:What patents and technology certifications back this HDPE PE100 pipe extrusion line?
A:
It holds multiple national utility patents, third party Level 5 technology rating, China's top independent tech verification for pipe extrusion machinery, plus Shandong Province First Set Technical Equipment award, credentials rarely offered by competing equipment.
Q:What industrial pipeline applications is this line specifically suited for?
A:
Oil gas transmission pipeline thermal insulation, chilled water distribution networks, chemical fluid transport pipelines, industrial hot medium pipeline systems, and municipal district heating infrastructure, any buried industrial pipeline requiring factory-prefabricated PUR foam pre-insulated pipe.
Q:What foam quality does the continuous PUR spray process achieve?
A:
Closed-cell ratio >=88% and water absorption rate <=0.05%, ensuring stable long-term thermal conductivity and structural integrity in harsh buried industrial pipeline service conditions where moisture ingress and foam degradation are primary failure risks.
Q:What pipe diameter range does this patented line cover?
A:
508-1620mm carrier steel pipe diameter, producing trinity molding structure pre-insulated pipes (steel carrier pipe + PU foam insulation + HDPE PE casing) with 30-100mm customizable foaming thickness meeting EN253, GB/T29047, and CJ/T114 international standards.
Q:Is this a complete turnkey system for industrial pipeline projects?
A:
Yes, Sa2.5 shot blasting, medium-frequency induction preheating, continuous PUR spray foaming, PE wrapping, and pipe end trimming are all integrated in one matched production line, eliminating separate vendor sourcing and integration risk for industrial pipeline insulation projects.
