A causa stressi thermali deformatione plasticae, elastica fertilis redundatur.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. Plus improvit fertilitatem fertilis fertilibus fertilibus aedificationis steelis.Ultima fortitudo frigidarum traxitarum tubarum absque calore graduale augebat, et deformatio plasticae tubarum absque calore rursum declinavit.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 aedificatione aut prefabricatione fabricationibus componentibus, hoc principium principium saepe ad ferventum aut frigidum trahendum steelam aut cabulas altum carbonum secundum quaecum specificationes utilitur.
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 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.
