PVC Pipe Production Line – Comprehensive Technical Dossier
General Overview
A modern PVC pipe production line is an integrated, fully-automatic system that converts raw PVC resin, stabilizers, lubricants, impact modifiers and fillers into standardized pipes for municipal water supply, drainage, irrigation, electrical conduit and industrial applications. The line is modular: each section can be upgraded, duplicated or bypassed to match market demands and regional standards (ISO, ASTM, DIN, GB/T, JIS). Typical configurations are single-strand (high diameter), dual-strand (medium diameter) and four-strand (small diameter), enabling a single plant to cover the entire product spectrum from Ø16 mm to Ø1000 mm without major retooling.
Core Process Flow
(1) Raw material handling: Vacuum loaders transfer resin and additives from silos to loss-in-weight feeders; gravimetric blenders guarantee ±0.2 % recipe accuracy.
(2) Hot-cold mixer group: A 500–2,000 L high-speed mixer (1,440 rpm) friction-heats the blend to 110–130 °C, followed by a 1,500–4,000 L low-speed cooler (70 rpm) that drops the temperature below 45 °C to prevent pre-gelation.
(3) Conical twin-screw extruder (SJZ series): The 38CrMoAlA screws are nitride-hardened to 950–1,000 HV and fitted with bimetallic flight tips for 30 % CaCO₃ recipes. A melt pressure sensor closed-loop-controls the screw speed to maintain constant head pressure (±0.2 MPa).
(4) Melt filtration: Dual-piston screen changers (120–400 mesh) with back-flush function remove gels, metal particles and unmelted agglomerates.
(5) Die head: Spiral mandrel design with chrome-plated flow channels; interchangeable die bushes and pins allow quick format change in < 20 min.
(6) Vacuum calibration and spray cooling: Two vacuum chambers (SUS304, 4–8 m long) create 0–-0.09 MPa to freeze the outer skin; a cascade water circuit (8–20 °C) and high-pressure sprayers remove heat at 30–80 kW/h.
(7) Haul-off: Multi-belt caterpillar units (top & bottom synchronized) use 1.5–5.5 kW servo motors per caterpillar; traction force is measured by load cells and auto-adjusted.
(8) Non-dust cutting: Planetary cutter for Ø16–250 mm (±1 mm end-cut squareness); saw cutter for Ø315–1000 mm with chip-extraction hood.
(9) On-line belling: Dual-oven sockets (Rieber or solvent-cement type) heat the pipe end to 150–180 °C; internal mandrel forms the socket; cooling ring sets the final dimension within ±0.3 mm ovality.
(10) Automatic stacking & bundling: Servo-driven pipe aligner and strapping machine create hexagonal bundles ready for shrink-wrapping.
