The huashida insulation pipe production line boasts a core
technology that stands at the forefront of China's industry. It
showcases numerous innovative points and design concepts,
effectively bridging gaps in domestic capabilities. Notably, four
pioneering core technologies—the solid-liquid phase separation
screw, spiral diverter head, DCL human-machine dialogue technology,
and real box external manipulator technology—are either the first
or among the earliest implemented in the sector. This
groundbreaking product stands as the sole domestic production line
capable of producing 1880mm large-diameter insulation pipes,
further solidifying its position as a leader in the field.
HDPE Jacket Process Flow:
- Vacuum Feeding of PE Granules: The raw PE granules are automatically fed into the system via
vacuum suction.
- Hot Air Drying: The granules are dried using hot air to remove moisture, ensuring
optimal extrusion quality.
- Extrusion Plasticizing: The dried granules are plasticized through the extruder, heated
and mixed to form a molten plastic mass.
- Mold Shaping: The molten plastic is shaped into the desired pipe profile by
passing through the extrusion die.
- Vacuum Sizing: The pipe is then subjected to vacuum sizing, adjusting its
dimensions to precise specifications.
- Water Cooling: The pipe is cooled rapidly by immersion in a water tank to
solidify its shape and structure.
- Pulling Out: The solidified pipe is pulled out of the cooling tank at a
controlled speed.
- Cutting: The pipe is cut to the desired length using a precision cutting
machine.
- Carrier Laying-off: The cut pipes are then neatly laid off onto a carrier for further
handling or packaging

gas/oil /water pipeline Puf Pre-Insulated Pipe PE shell casing
plastic Machinery Advantages:The inclusion of PUF (Polyurethane Foam)
- Reduced Heat Losses:
- By effectively insulating the pipeline, PUF insulation minimizes
heat losses to as low as 8%, significantly outperforming
traditional insulation methods that often suffer from heat losses
of 30-40%. This enhanced thermal efficiency leads to lower energy
consumption and reduced operating costs.
- Capital Cost Savings:
- The cost-effectiveness of PUF insulation is further evident in the
reduction of capital costs by 15-20%. This is primarily due to the
elimination of the need for concrete channels and chambers for
valves, which are often required in traditional pipeline systems.
- Reduced Operating Costs:
- The improved thermal efficiency and reduced heat losses lead to a
significant reduction in operating costs. Specifically, the use of
PUF insulation can result in operating cost savings of up to 9
times compared to traditional systems.
- Lower Repair Costs:
- The durability and resilience of PUF insulation reduce the
frequency and severity of repairs, leading to a 3-fold decrease in
repair costs. This not only saves money but also minimizes the
inconvenience and downtime associated with repairs.
