Internal Pipe Shot Blasting Machine

Our internal pipe shot blasting machine is made for treating inner surfaces of pipes, cylinders, and pressure vessels. The model is QGN series. It uses an axial moving shot blaster that goes deep inside. High-speed shots (steel shots or steel wire cut shots) hit the inner wall. They remove rust, oxide scale, welding slag, and oil. The result is a clean metal surface with uniform roughness. This improves coating adhesion and anti-corrosion life.Jiangsu Haike Environmental Tech Co., LTD has 28 workers and a 30-acre factory. We are a high-tech company with many patents since 2014.

The workpiece is fixed or rotated. The shot blaster moves along the axis at a steady speed. It throws shots 360 degrees. There is a sealing device to prevent shot leakage and an automatic recycling system. This internal pipe shot blasting machine works for seamless steel pipes, oil pipes, chemical pipes, wind tower cylinders, pressure vessels, and cast iron pipe inner walls. The core benefits are full coverage, no dead spots, high efficiency, replacing acid pickling, and environmentally friendly with no pollution.

Walking speed is 0.1-1.6 m/min. Shot flow is 40-220 kg/min. Workpiece speed is 0.5-8 r/min. Full data available from engineer.

A steel pipe plant in Tianjin made oil pipes. The pipes needed inner wall anti-corrosion.But there was rust and oxide scale. Coating adhesion was poor. We installed a HKQGN1200 internal pipe shot blasting machine. After treatment, the inner wall reached Sa2.5 standard. Coating adhesion improved greatly. The customer passed strict oil industry tests. Now they use our machine for all their oil pipes.
