The basic principle of Q345B square tube pull-out structure reinforcement: the disadvantages of the lattice constant of steel in plastic deformation are increased, and the disadvantages of the lattice constant are more serious. The deformation will prevent further loading of the lattice constant, which will make the steel yield limit development, plastic deformation and resistance. The force is reduced.


   Because of the thermal stress caused by plastic deformation, the elastic mold of steel is reduced. Cold drawn building steel bars are stored at indoor temperature for 15-20 days, or heated to 100-200 degrees Celsius for a certain period of time. This whole process is called solution treatment after cold drawing. It further improves the yield limit of cold-drawn building steel bars. The ultimate compressive strength of cold drawn seamless pipes has gradually increased, and the plastic deformation of seamless square pipes has decreased again. Because of the reduction of thermal stress in the whole process of aging, the elastic mold foundation of the precision seamless steel pipe additive manufacturing process can be repaired. In order to improve the tensile strength and save stainless steel plates, in building construction or prefabricated component factories, this basic principle is often used to cold-drawn or cold-drawn building steel or high-carbon steel cables according to certain specifications.


Many specifications of square steel pipes are used as pipelines for transportation of fluid mechanics, such as the transportation of crude oil, Q345B square pipe-Q345B seamless square pipe-Q345B square steel pipe-Q345B cold drawn square pipe-Shandong Dingyu Metal Materials Co., Ltd. Gas, liquefied gas, water and Some solid raw material pipelines, etc. Large-diameter square pipes are also commonly used to produce parts and mechanical parts, such as crude oil drilling tools, drive shafts, bicycle frames and steel pipe scaffolds used in construction projects.


  Advantage


Q345B square tube is compared with solid stainless steel plates such as Yuangang Steel, seamless square tube has a lighter net weight when the bending strength, torsion and compression strength is the same. And mechanical parts, precision seamless steel pipe additive manufacturing process types such as crude oil drilling tools, drive shafts, bicycle frames and steel pipe scaffolds used in construction projects. The use of seamless steel pipes to produce ring parts can increase the utilization rate of raw materials. Seamless square pipes simplify the production and manufacturing process, save raw materials and comprehensive man-hours for production and processing, such as roller bearing rings, hydraulic jack sleeves, etc., at this stage. Seamless steel pipes are commonly used for manufacturing.
