This internal shot blasting line is specifically engineered to clean the inside surface of steel pipes before internal lining applications. Designed for FBE (fusion bonded epoxy), liquid epoxy, or cement mortar lining processes used in oil, gas, and water pipelines, this system utilizes a rotating spinner-wheel blast head that travels the entire length of the pipe bore.

Unlike external blasting systems that clean pipe exteriors for 3LPE/3PE coating, this machine throws steel shot against the internal wall to uniformly strip rust, mill scale, and contaminants from end to end. The system ensures full, even coverage inside pipes ranging from 3-12 meters in length while maintaining consistent shot velocity and impact angle throughout the process.

• Cleans full internal bore to Sa2.5 - Sa3 standards required for internal lining specifications
• Automated indexing and rotation eliminates manual repositioning between passes
• Closed-loop shot recovery system reduces abrasive consumption compared to open systems
• Configurable for pipe internal diameters from 80mm up to 4000mm
• Seamlessly integrates with downstream internal FBE/epoxy lining equipment for continuous operation

• Oil and gas pipeline internal lining preparation
• Water and wastewater transmission pipe interior cleaning
• Pipe interior preparation prior to internal FBE or epoxy coating
• Retrofit derusting of stored or stockpiled pipe before lining
