Product Description

Product Description
Seamless square tube is a kind of long strip steel with hollow section and no seam around it. It is a square tube formed by extrusion of seamless tube through four sides of die. Square tube has hollow section and is widely used as a pipe for conveying fluid. It is mainly used in liquid transportation, hydraulic support, mechanical structure, medium and low pressure, high pressure boiler pipe, heat exchange pipe, gas, oil and other industries. It is stronger than welding and will not crack.
