Boyu Petro four-station hydro tester is a high-performance pressure testing machine designed for steel pipes and tubes. It fills pipes with high-pressure water to perform structural integrity tests and detect leaks or defects. This four-station hydrostatic test machine features a four-pipe design, allowing four pipes to be tested simultaneously. This significantly improves testing efficiency for high-volume OCTG production lines while maintaining accurate pressure control and data recording.
