A pipe shot blasting system for pipeline preparation is a specialized industrial solution designed to clean, descale, and profile the interior and exterior of pipes, ensuring optimal adhesion for protective coatings and long-term durability. These systems are critical in oil and gas, water treatment, and infrastructure sectors, where pipelines must withstand corrosive environments, high pressure, and extreme temperatures.
The system’s modular design accommodates pipes ranging from 2 inches to 60 inches in diameter and up to 40 feet in length, with adjustable conveyor speeds (0.5–5 meters per minute) to match production demands. High-velocity centrifugal wheels (10,000–15,000 RPM) propel steel shot or garnet abrasives, targeting both outer surfaces and inner bores via flexible lance systems with rotating nozzles. This ensures uniform coverage, even around weld seams, elbows, and flanges.
Key features include automated diameter sensors that adjust blasting intensity in real-time, preventing over-treatment of thin-walled pipes while ensuring thick-scale removal on heavy-gauge steel. A closed-loop media recycling system uses magnetic separators and air classifiers to reclaim up to 95% of abrasives, reducing operational costs and environmental waste.
Post-blasting, inline inspection tools—such as surface roughness gauges (Ra 25–75 microns) and ultrasonic thickness testers—verify compliance with standards like NACE SP0169 and ISO 8501-1. In oil and gas applications, this preparation ensures fusion-bonded epoxy (FBE) coatings adhere securely, preventing corrosion-related leaks. For water pipelines, it removes biofilm and mineral deposits, restoring flow efficiency. By combining precision with scalability, pipe shot blasting systems are essential for reliable, long-lasting pipeline infrastructure.
