Dissolvable Magnesium Alloy Tube
A high-strength seamless thick-walled tube for dissolvable screens, downhole tool mandrels and similar components. Developed for high-temperature, high-pressure reservoirs; supports up to 204°C with good corrosion and pressure resistance. Dissolves controllably in specific fluids, enabling circulation in sand control screens. Widely used in shale gas and tight oil completion and sand control.
