• Typical Applications:
  • ZY16: Refrigerator condenser pipes (φ16mm), medical bed frame pipes (ISO 13485 certified);
  • ZY32 (φ12.7-φ38.1mm): Washing machine inner drum support pipes, wheelchair armrest pipes.
• Key Configurations:
  • Pneumatic double-roll uncoiler (supports 1.5-2.5-ton coils), suitable for small-batch, multi-specification production;
  • Food-grade lubricants (ZY16) prevent contamination risks in medical device pipes.

2. General Industrial Sector: Large-Scale Production of Multi-Specification Pipes

Suitable Models: ZY45, ZY50, ZY60

2.1 Construction and Infrastructure Projects

• Main Models:
  • ZY50 (φ20-φ63.5mm, wall thickness 0.8-3.0mm): Scaffolding pipes (φ48mm), steel structure pipes, supporting square/rectangular pipe production;
  • ZY60 (φ20-φ76mm): Bridge stay pipe casings, photovoltaic support pipes, with single-shift capacity reaching 18-20 tons.
• Efficiency Design:
  • Split-type machine train + horizontal spiral accumulator (ZY50/60) supports 4-6-ton coil continuous production, with roll change time <30 minutes;
  • Three-roll welding extrusion stand ensures weld tensile strength ≥85% of base material, meeting API 5L standards.

2.2 Furniture and Machinery Manufacturing

• Application Scenarios:
  • ZY45 (φ12.7-φ50.8mm): Office desk and chair frame pipes, hydraulic cylinder pipes;
  • ZY60: Outdoor guardrail pipes (square 60x60mm), industrial robot structural pipes.
• Technical Highlights:
  • Turk head straightening device (ZY45/60) ensures pipe flatness error <0.3%;
  • Optional online punching function reduces post-processing steps for furniture pipes.

3. Heavy Industry Scenarios: High-Strength Demands for Large-Diameter and Thick-Wall Pipes

Suitable Models: ZY76, ZY89

3.1 Petrochemical and Energy Industries

• Core Specifications:
  • ZY76 (φ30-φ89mm, wall thickness 1.2-4.0mm): Oil transmission pipelines, refining equipment connecting pipes, supporting hydraulic testing at 10MPa;
  • ZY89 (φ38-φ102mm, wall thickness 1.2-4.5mm): High-pressure gas transmission pipes (φ102mm), pressure vessel pipes, passing -40°C low-temperature impact tests.
• Industrial-Grade Configurations:
  • Hydraulic uncoiler (supports 5-ton coils) + 300kW solid-state high-frequency welder, with first-pass weld qualification rate 98%;
  • Four-roll Turk head + dual-stand straightening ensures roundness error <0.3% for large-diameter pipes.

3.2 Heavy Machinery and Infrastructure

• Typical Applications:
  • ZY76: Excavator boom pipes (φ89mm), crane support pipes;
  • ZY89: Port equipment pipes, large bridge steel structure pipes, compliant with international standards like ASTM A106.
• Durability Design:
  • Roll materials use 42CrMo quenched and tempered with high-frequency hardening, lifespan >2000 hours;
  • Cooling system flow ≥15 tons/hour supports 24-hour continuous heavy-duty production.

4. Selection Guide: Three Steps to Match the Optimal Model

4.1 Filter by Pipe Specifications

• Small diameter (<φ30mm): ZY16-ZY32 for precision forming in automotive and home appliance industries;
• Medium diameter (φ30-φ80mm): ZY45-ZY60 for balancing efficiency and precision in construction and machinery;
• Large diameter (>φ80mm): ZY76-ZY89 for high-pressure and thick-wall needs in energy and heavy industry.

4.2 Choose by Production Mode

• Small-batch customization: Integrated machine trains (ZY16-ZY32) with manual roll change for flexible sample prototyping;
• Mass production: Split-type machine trains (ZY45-ZY89) with automatic accumulators and independent drive systems, enhancing efficiency by 50%.

4.3 Commercial Terms Reference

• Delivery Cycle: Shipment within 4 months after advance payment, with Russian/English operation manuals and localized after-sales support;
• Warranty Policy: 1-year full machine warranty (excluding consumables), with spare parts drawings shipped with the equipment.
