Automatic coupling spray coating line

The UV color ring sprayer is a mandatory equipment for OCTG tubing production lines per API 5CT standards. Its core function is to accurately spray UV color rings corresponding to different steel grades (e.g., J55/K55, N80, P110) on the tubing body or coupling surface, enabling rapid steel grade identification. It is a key link for products to leave the factory compliantly and ensure safe oilfield operations.

产品描述

- Commodity name: UV Color Ring Sprayer for OCTG Tubing (API 5CT Compliant Model)
The UV color ring sprayer is a mandatory equipment for OCTG tubing production lines per API 5CT standards. Its core function is to accurately spray UV color rings corresponding to different steel grades (e.g., J55/K55, N80, P110) on the tubing body or coupling surface, enabling rapid steel grade identification. It is a key link for products to leave the factory compliantly and ensure safe oilfield operations.
Positioning
- Meets API 5CT mandatory requirements: Strictly aligns with standards for color ring color, width, and position to avoid steel grade confusion.
- Replaces traditional manual painting, solving problems such as low efficiency, uneven color rings, and easy peeling.
Configuration & Functions
- Conveying & Positioning: Adapts to tubing of Φ10-630mm diameter and 3-18m length; automatic clamping and rotation with positioning accuracy ≤±1mm.
- UV Spraying: Dedicated UV printhead, color ring width error ≤±0.5mm, no breaks or color differences.
- Curing Assurance: UV ink cures quickly, resistant to temperature and oil, without smudging during handling and warehousing.
- Intelligent Control: Preset color ring parameters for different steel grades, one-key switching, and automatic alarms for low ink levels and faults.
Advantages
- Compliance: Fully meets API 5CT standards to ensure smooth factory delivery.
- High Efficiency: Spraying speed of 10-15 pieces/minute, 3-5 times faster than manual operation, supporting 24/7 continuous production.
- Wide Adaptability: Compatible with full-range OCTG tubing, model changeover time <5 minutes.
- Environmental & Durable: No gas or dust emissions; UV color rings are weather and wear resistant, with long-term non-peeling performance.
- Intelligence: Connectable to MES systems for data traceability.
Application Scenarios
- Production enterprises of OCTG tubing, casing, and nipples; used for steel grade marking after finished product inspection, suitable for oilfield exploitation, oil and gas transmission, and other scenarios.
