Custom PVC-Steel Wire Reinforced Pipe Extrusion Line

Model	Extruder	Diameter(mm)	Capacity(kG/h)
PE75	SJ75/30	75	120-150kg/h
PE90	SJ90/30	90	150-200kg/h

Equipped with automatic material feeding and tension feedback loops, this line ensures consistent production quality even during 24/7 continuous operation, making it widely recognized in fluid transportation industries for its stable production capacity, low defect rate (≤0.5%), and ability to adapt to diverse raw material formulas.

Product Features

Extrusion System: Equipped with a 38CrMoAlA alloy screw (undergoing nitriding treatment for enhanced wear resistance) and barrel, the extruder achieves a maximum extrusion capacity of 200kg/h with temperature control precision of ±1℃. The screw’s optimized groove design promotes uniform melting of PVC raw materials, reducing material waste by up to 8% compared to standard extruders.

Reinforcement Technology: The automatic steel wire tension control system—equipped with real-time tension sensors—maintains tension stability within 0.5-2.0N, ensuring the spiral pitch error is less than ±2mm for consistent pressure resistance across the entire hose length. The steel wire feeding unit also features a pre-straightening function to eliminate wire kinks that could affect product performance.

Control System: Adopts a 7-inch touchscreen PLC control (compatible with remote monitoring via mobile APP) with real-time monitoring of 12 key parameters (including temperature, pressure, and tension). It supports one-click recipe storage for 50+ hose specifications, enabling quick switch between production tasks (typically within 15 minutes for standard size changes).

Cooling Module: Three-stage water cooling system (with adjustable water flow and temperature) reduces hose temperature from 180℃ to 45℃ within 3 meters. The cooling tank’s internal guide rollers are coated with wear-resistant rubber to prevent hose surface scratches, further improving dimensional accuracy (outer diameter tolerance ≤±0.3mm).

Applications

Industrial Fluid Transportation: Ideal for conveying oil, emulsion, and chemical reagents (with pH ranges 4-9) in machinery factories, supporting working pressures up to 1.6MPa. The hoses’ inner wall smoothness (Ra ≤0.8μm) minimizes fluid resistance, ensuring stable flow rates for precision manufacturing processes.

Municipal Engineering: Suitable for drainage hoses in road construction and tunnel dewatering projects, as the reinforced structure resists soil pressure of 200kN/m² and prevents hose collapse in deep burial scenarios (up to 5 meters underground).

Agricultural Irrigation: Produces large-diameter hoses (φ50-300mm) for farmland sprinkler irrigation systems. The hoses are formulated with UV-resistant additives, enabling 5+ years of outdoor use without aging or cracking, even in regions with strong sunlight (e.g., desert or tropical areas).

FAQ

Q: What is the maximum hose diameter this line can produce?

A: It supports diameter ranges from φ25mm to φ150mm for standard models; customized molds are available for special sizes (up to φ600mm) with a 2-3 week lead time for mold fabrication.

Q: How often does the steel wire feeding mechanism need maintenance?

A: Routine lubrication of the feeding rollers is required every 200 working hours, and a full inspection (including tension sensor calibration and wire guide adjustment) is recommended every 1000 working hours to ensure tension stability. For high-dust environments, additional air filtration for the tension sensor is advised to prevent accuracy drift.
