Q345C welded steel pipe: performance and application

Q345C welded steel pipe Q345C steel used belongs to low alloy high strength structural steel. This kind of steel pipe has good comprehensive mechanical properties, the yield strength is not less than 345MPa and the tensile strength can be more than 470MPa, which can withstand large loads and stresses in many projects. In the field of construction, Q345C welded steel pipe can be used in building frames, trusses and other structures to provide stable support for buildings.

Its good toughness makes Q345C welded steel pipe less prone to brittle fracture when exposed to dynamic loads such as shock or vibration. For example, in bridge construction and lifting equipment, this type of steel pipe can work reliably. Meanwhile, Q345C welded steel pipe has good welding performance, which is convenient for all kinds of welding processing, ensures the quality and strength of welded joints, reduces the difficulty and cost of welding, and is widely used in the fields of machinery manufacturing and so on.

The pipe is manufactured by straight seam electric welding process, the weld seam of Q345C welded steel pipe is straight, compared with spiral welded steel pipe, the length is shorter, less welding defects, the quality is easier to control, which ensures the stability of the overall quality and performance. gb/T13793-2008 standard strictly regulates the manufacturing process of Q345C welded steel pipe, including the selection of raw materials, welding process parameters, including raw material selection, welding process parameters, and so on. The GB/T13793-2008 standard strictly regulates the manufacturing process of Q345C welded steel pipe, including the selection of raw materials, welding process parameters, dimensional accuracy and surface quality. The strict requirements make Q345C welded steel pipe have wide application prospects in petrochemical, bridge, water conservancy, electric power and other engineering fields.
