GB/T 13793 specifies the classification, code, order content, size, shape, weight and allowable deviation, technical requirements, test methods, inspection rules, packaging, marking and quality certificate of straight seam welded steel pipes. Production process of large-diameter straight seam steel The use of large-diameter straight seam steel pipes is mainly used for body supporting parts, such as bridge piling, subsea piling, and high-rise building piling. The materials used for large-diameter straight seam steel pipes are generally Q345B and Q345C. Q345D is also used in areas with low temperatures.

Q345 Steel Properties and Introduction. Q345 steel is a Chinese GB standard Low Alloy High Strength Structural Steel, material density is 7.85 g/cm3, tensile strength is 470-630 Mpa, and yield strength is 345 MPa (datasheet tested with 16mm diameter steel bars or steel plates).According to GB/T 1591 2008, Q345 material has 5 quality grades:Q345A, Q345B, Q345C, Q345D and Q345E. Q345b steel polishing method, Q345B steelThe tensile strength of Q345B steel is rated at 470 to 630 MegaPascals (where mega is million) and a yield strength (where the material starts to thin and pull like taffy) at 345 MegaPascals. Like most steels of its grade, it suffers elongation before it pulls apart, typically at 20-21 percent of its initial length.
