PVC Corrugated Pipe

PIPLL PVC Corrugated Pipe Extrusion Screws | Single & Double Wall Solutions
With 20+ years of expertise, PIPLL leads in high-performance extrusion screw and barrel systems. Our PIPLL PVC corrugated pipe screws are engineered for PVC's thermosensitivity and corrugated pipe forming. PIPLL delivers tailored solutions for small single-wall or large double-wall pipes, maximizing productivity, quality, and equipment lifespan. PIPLL perfectly matches all mainstream extruders, including KraussMaffei and Jwell.

PIPLL Single Wall PVC Corrugated Pipe Screws
Designed for high-speed lines, PIPLL single-wall screws feature optimized feeding and gradual compression. They deliver 300-800 kg/h, keep melt temperature fluctuation within ±2°C, and cut energy use by 15%-20%. Compatible with Φ45-Φ92 mm parallel and Φ51-Φ110 mm conical twin-screw extruders, they suit DN16-DN400 pipes.

PIPLL Double Wall PVC Corrugated Pipe Screws
PIPLL double-wall screws optimize simultaneous inner/outer wall forming and high ring stiffness. A three-stage mixing system ensures uniformity, while precise compression control (2.0:1-2.5:1) boosts ring stiffness by 10%-15% to meet SN8+ standards. They support Φ80-Φ132 mm parallel and Φ65-Φ150 mm conical twin-screw extruders for DN110-DN1200 pipes.

PIPLL Core Tech & Quality
PIPLL features patented gradient shear to prevent melt decomposition, barrier mixing for 50% better surface finish, and bimetallic wear resistance (HRC58-62) for 3-5x durability. Precision temperature control ensures ±1.5°C accuracy.
PIPLL offers end-to-end customization and ISO 9001-certified quality, with CNC-machined screws (±0.05 mm accuracy) and rigorous inspection.

Common Production Issues & PIPLL Solutions

Production Issue	Root Cause with Standard Screws	PIPLL Specialized Screw Solution
Pipe yellowing & black spots	Excessive shear heat causing PVC local decomposition	Low-shear gradient design + screw core water cooling to control melt temperature
Poor corrugation forming & irregular shape	Unstable melt pressure and uneven plasticization	Barrier mixing section + optimized homogenization zone to stabilize extrusion pressure
Uneven wall thickness & insufficient ring stiffness	Inconsistent melt viscosity and temperature fluctuation	Three-stage mixing system + precision temperature control to ensure melt uniformity
White spots & unmelted particles in pipes	Incomplete plasticization	Spiral barrier structure to crush all unmelted particles
Fast screw wear & short service life	Low material hardness and poor wear resistance	Bimetallic centrifugal casting process, 3-5 times higher wear resistance
Low output & high energy consumption	Low conveying efficiency and high material flow resistance	Large-volume feeding section + optimized thread profile to improve conveying efficiency
