Brief: Get a guided demo that shows common workflows and troubleshooting tips for Huashida's thermal insulation pipe production line. Watch as we demonstrate the fully automated process of manufacturing precision pre-insulated bonded pipe systems, showcasing the vacuum-calibrating technology that ensures uniform wall thickness and dimensional stability at high line speeds.
Related Product Features:
  • Fully automated production line manufactures precision pre-insulated bonded pipe systems in a single continuous pass.
  • Vacuum-calibrated crosshead ensures uniform wall thickness with ovality ≤ 0.5% and surface roughness Ra ≤ 6 µm.
  • Closed-loop vacuum control (±0.2 kPa) automatically compensates for melt-temperature and haul-off variations.
  • Produces dimensionally stable outer jacket that locks polyurethane foam and carrier pipe into one composite structure.
  • Capable of manufacturing pipes from Φ110mm to Φ1860mm diameter with line speeds up to 2.5 m/min.
  • Reduces scrap to less than 1% through advanced process control and vacuum calibration technology.
  • High-efficiency extruder provides larger output and stable performance with minimal raw material waste.
  • Features four core technologies including solid-liquid phase separation screw and spiral diverter head.
FAQs:
  • What diameter range can this production line handle?
    The production line can manufacture pipes ranging from Φ110mm to Φ1860mm in diameter, with specific models optimized for different size ranges including PE-110/600, PE-365/760, PE-655/1380, PE-960/1680, and PE-1054/1860.
  • How does the vacuum calibrating technology improve pipe quality?
    The vacuum-calibrated crosshead immediately after the PE extruder pulls the melt against a precision sleeve, ensuring uniform wall thickness, ovality ≤ 0.5%, and surface roughness Ra ≤ 6 µm. Closed-loop vacuum control (±0.2 kPa) automatically compensates for variations, eliminating diameter drift.
  • What are the operational benefits of this automated production line?
    The line offers high automation requiring only one operator, reduces scrap to less than 1%, provides stable performance with larger output, and produces pipes ready for direct burial or offshore reel-lay without secondary sizing or machining.
  • What makes this production line suitable for international projects?
    The line produces pre-insulated pipes with increased service life of 30-40 years, reduces heat losses to 8%, lowers capital costs by 15-20%, and reduces operating costs by 9 times compared to traditional pipeline systems.
