PE Small Pipe Extrusion Line — High-Speed LDPE/LLDPE/HDPE Tube Manufacturing
What It Is

Our PE Small Pipe Extrusion Line is a turnkey solution for producing micro to small-diameter polyethylene tubes (LDPE/LLDPE/HDPE). It combines optimized screw design, precise temperature zones, PLC + touchscreen HMI, and closed-loop line synchronization to deliver uniform wall thickness, smooth surface finish, and stable 24/7 output.
Key Features & Benefits
- High speed & stability – Optimized screw/barrel and melt filtration enable continuous, stable extrusion with consistent OD/ID.
- Precision sizing – Vacuum calibration and multi-stage spray cooling keep ovality low; online diameter/Wall-thickness measurement available.
- Energy efficiency – Insulated heating zones and VFD drives reduce kWh per kg; closed-loop water system optional.
- Smart operation – PLC + HMI for recipe management, line-wide synchronization, alarms, and production data export.
- Fast changeovers – Quick-change die heads and adjustable sizing sleeves minimize downtime for multi-spec production.
- Compliance & safety – CE/UL-ready electricals, interlocks, and EMC design.
Typical Applications
- Wire & cable conduit / lead tubes – Low-friction bore, abrasion resistance.
- Micro-irrigation lateral / dripper line – Flexible, durable small OD tubing.
- Home renovation micro tubing – Water, air, or signal routing.
- Medical & lab tubing (material and regulatory review required).
- Packaging straws / protective tubes / bubble-film skeleton microtubes.
Process Flow
Feeding & drying (as needed) → Extrusion & melt filtration → Die head & vacuum sizing → Multi-stage water cooling → Haul-off (closed loop) → Metering & coding → Cutting/Coiling → In-line QC & packaging
Core Modules
- High-efficiency single-screw extruder (nitrided barrel, wear-resistant screw, optimized L/D)
- Precision die head with quick-change tooling
- Vacuum calibration tank (stable vacuum, level & temp control)
- Spray cooling tanks (closed-loop option)
- Servo or caterpillar haul-off, synchronized with main extruder
- Fly-knife or planetary cutter / servo coiler (small pipe commonly uses coiler)
- Meter counter, inkjet/laser coder (optional)
- Online diameter & wall-thickness gauge with SPC (optional)
Technical Specifications (customizable)
- Pipe OD range: Ø 2–32 mm (options down to Ø 1.5 mm or up to Ø 40 mm)
- Line speed: up to 60 m/min depending on OD, material, and cooling capacity
- Throughput: approx. 80–180 kg/h*
- Energy consumption: 0.28–0.45 kWh/kg*
- Control system: PLC + 7”/10” HMI; recipe/alarms/data export
- Utilities: Electrical per region, process water; closed-loop chiller recommended
- Standards: CE/UL (optional)
*Actual data depends on your target size, formulation, and configuration.
Quality & Cost Control
- Wall-thickness uniformity: Balanced melt flow + stable vacuum reduce eccentricity.
- Surface finish: Tuned cooling profile mitigates orange-peel and water marks.
- Lower cost per meter: Energy-saving design, low scrap rate, and easy maintenance cut operating costs.
