Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and A709 Gr HPS70W bridge steel plate resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, A709 Gr HPS70W bridge steel plate new materials, and promotes the competition of enterprises Struggle.
The main steel plates for oil and gas pipelines are X42, X46, X52 (L360), X56 (L390), X60 (L420), X65 (L460), X70, X80. The specification range of steel plate used by the company for oil and gas pipelines: thickness 8mm-60mm. It can produce additional flaw detection requirements and Z15-Z35 tear resistance (thickness direction performance) steel plates A709 Gr HPS70W bridge steel plate, and can also provide Z-direction performance steel plates according to ASTM A770 and other standards.
Generally, the steel plates for boiler and pressure are divided into categories. A516 gr60 carbon steel plates have a maximum thickness that varies on the capacity. The tensile strength, elongation, yield strength, and hardness are the mechanical properties of these plates. Physical and chemical characteristics of the boiler quality plates A709 Gr HPS70W bridge steel plate make these a popular choice in the industries. Also, these carbon steel are made up of premium quality raw materials by the use of the latest machinery and are therefore of robust built.
Non-destructive flaw detection of steel plates is a test method for inspecting the A709 Gr HPS70W bridge steel plate surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Commonly used A709 Gr HPS70W bridge steel plate steel plate flaw detection methods include: X-ray flaw detection, ultrasonic flaw detection, magnetic particle flaw detection, penetration flaw detection, eddy current flaw detection, gamma-ray flaw detection, fluorescent flaw detection, color flaw detection and other methods. Physical flaw detection is non-destructive flaw detection without any chemical changes.
According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for A709 Gr HPS70W bridge steel plate, 42CrMo steel is quenching and tempering.
