Technical Specifications & Industrial Benchmarks

1. Key Features & Automated Workflow

• Intelligent Powder Dosing & Feeding: Equipped with spring feeders or vacuum hoppers with anti-bridging agitators to maintain steady feeding of PVC compound powders and additives.

• Precision Conical Twin Screw Extruder: Features alloy-treated 38CrMoAlA screws with internal oil cooling, preventing local overheating and ensuring homogenous melt distribution.

• Spider-Type Extrusion Die Head: Engineered with chrome-plated flow channels that reduce melt resistance, producing pipes with uniform wall thickness and flawless surface finish.

• Vacuum Calibration & Intense Cooling Tanks: Heavy-duty stainless steel tanks utilize spray nozzles and negative pressure control to lock in exact pipe dimensions without surface distortion.

• Synchronized Puller & Dust-Free Cutter: Multi-claw haul-off units synchronized via Siemens PLC ensure constant linear speed, followed by planetary cutters for smooth end bevels.

2. Core Market Applications

■ Building Cable Protection & Electrical Conduits

High-speed double-strand or four-strand PVC pipe machinery produces small-diameter flame-retardant electrical sleeve pipes for residential and commercial wiring.

■ Municipal Water Supply & Drainage Lines

Heavy-duty extrusion setups manufacture rigid UPVC pressure pipes for city water mains, rain drainage systems, and underground sewage networks.

■ Agricultural Micro-Irrigation & Well Casing

Corrosion-resistant PVC pipes extruded by Qinghang machinery withstand harsh chemical fertilizers, ground pressure, and UV exposure for farm irrigation grids.
