Supplier's note

  1. Technical Breakthroughs:

    • Seamless Construction: Eliminates joints, reducing leakage risks in high-pressure systems.
    • Alloy Grades: 42CrMo4 and 50crmo4 offer 20–35% higher strength than carbon steel, ideal for extreme environments.
    • Cold-Drawn Process: Achieves ±5% tolerance, enabling precision fits in machinery.

  2. Version Selection Guidance:

    • Base Model: Suitable for general construction (e.g., structural supports) where cost-efficiency is prioritized.
    • Advanced Model: Best for hydraulic systems and drilling equipment needing enhanced strength.
    • Pro Model: Designed for oil/gas pipelines and boiler systems requiring extreme pressure resistance (up to 300 bar). Pair its thick-wall design with cold-drawn finish for seamless fluid flow and corrosion protection.

With the Pro version’s 300 bar pressure rating, you can safely handle high-pressure chemical processes. The Advanced Model’s 250 bar capacity makes it perfect for automotive hydraulic systems. Choose the Base Model for cost-effective structural applications.
