This means the column jack is placed flat on the ground, and the center cylinder and plunger are extended and retracted horizontally. This horizontal pressure test does not represent the column's true working state. During horizontal pressure testing, pressure is concentrated on the inner walls of the outer and center cylinders. Due to gravity, after several pressure tests, many long, straight scratches will form on the outer walls of the center cylinder and plunger. This affects the quality of the weld deposit area, accelerates corrosion during the product's life cycle, and impacts overall quality and service life. Furthermore, existing pressure tests can only be performed individually, severely impacting production efficiency.
