Optimizing Internal Pipe Cleaning

Internal pipe blasting is one of the most demanding applications in the oil and gas sector. The goal is simple: achieve a Sa 2.5 finish for optimal coating adhesion. The execution, however, is complex.

The Challenge of Depth

Cleaning pipes up to 24 meters in length requires a stable, high-speed nozzle feed system. Any vibration or speed fluctuation results in an uneven finish.

Technical Highlights of the JW-SPI Series:

  • Nozzle Feed Speed: 0.5~8m/min (Adjustable)
  • Rotation Speed: 50~300r/min
  • Internal Qualification Rate: ≥99%

Why It Matters

A poorly cleaned pipe will fail prematurely due to corrosion. By ensuring a consistent roughness and total removal of rust, Kingwo helps extend the lifespan of critical infrastructure by decades.

Global Success

Our systems are currently operating in major pipeline projects across the USA and Germany, proving that our "non-standard" approach is the global standard for quality.
