      What is hot dip galvanized square bending moment pipe? Hot dip galvanized square bending moment pipe is the name of square pipe and rectangular pipe, that is, the length of steel pipe is the same. Through process treatment, line pressing. In the production process of hot-dip galvanized square bending moment tube, there are no pitting, iron oxide scale and other defects in the hot-rolled bending moment tube, such as good surface quality, high finish, high dimensional accuracy of cold-rolled products. The performance and microstructure of the product can meet some special requirements, such as electromagnetic performance, deep drawing performance and so on. It has good wear resistance, that is, wear resistance.

      The plastic performance analysis of hot dip galvanized square tube refers to the ability of metal materials to avoid plastic deformation under load. The hardness of products is measured by indentation hardness method. A certain geometric indentation head is used to press into the surface of the metal material to be tested, and the hardness value is determined according to the degree of indentation. The mechanical properties of metal under static load are analyzed, such as strength, plasticity and hardness. In fact, many mechanical parts work under cyclic load, and the parts will fatigue under cyclic load. The impact toughness of hot dip galvanized square pipe is analyzed by performance index
