A low-alloy seamless square tube is a long strip of steel with a hollow section and no joints around the perimeter. Steel pipes have a hollow section and are used in large quantities as pipes to transport fluids. It is mainly used in liquid conveying, hydraulic support, mechanical structure, medium and low pressure. High-pressure boiler tubes, heat exchange tubes, gases. petroleum and other industries.
