The Use and Classification of Square Pipes
Square Steel Pipe is usually used in steel structures, structural curtain walls, machinery manufacturing, building materials, shipbuilding, airport, liquid transportation and other fields. Seamless Square Tube is a round tube without joint extrusion, that can be used for liquid delivery. Slotted square pipes can be welded with steel plates and are commonly used in steel structures. Plasticity refers to the ability of a metal material to slow down the plastic deformation (permanent deformation) of a metal shape under loading without damage. Hardness is the ability of a metal material to combine hard and soft. Over-steel is easy to embrittlement, and too soft is non-plastic. Now in square steel pipe detection, the commonly used method is the indentation hardness detection method. Measure the degree of indentation by squeezing the square tube against the rectangular tube. At present, the angle size, corner angle, and straightness of cold rolled square pipe used in steel struct...
