Q345R pressure vessel steel sheet cold working and aging

After heating, a billet is refined for several passes of rolling, then edge cutting and straightening to become a Q345R pressure vessel steel sheet steel plate, which is called hot rolling. Due to its high strength, good toughness, easy processing, good weldability and other excellent properties, hot rolled steel plate products are widely used in shipbuilding, automobile, bridge, construction, machinery, pressure vessel and other manufacturing industries.

BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of Q345R pressure vessel steel sheet steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main Q345R pressure vessel steel sheet production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.

Cold rolled Q345R pressure vessel steel sheet steel sheet can be produced by two high mill, four high reversing mill, multi high reversing mill and tandem cold mill. Although there are still only two work rolls in four high and multi high rolling mills, each work roll is supported by one or more large diameter backup rolls, which can prevent deflection of work roll. As a result, wide and thinner Q345R pressure vessel steel sheet steel plates can be produced. For example, 20 high mill can produce as thin as 0. 001 mm sheet, but the two high mill can only produce as thin as 0. 35mm sheet

X42 steel plate/pipes, API 5L X42 steel plate/pipes, under API 5L standard, we can regard Q345R pressure vessel steel sheet pipe, X42 steel plate/pipes as large diameter pipes. X42 steel plate/pipes is one mainly of Steel for large diameter pipes, API-X42 steel used for pressure liquid transport, oil, gas, water and other liquid transportation, oilfield engineering, ductwork, construction, steel pipe and oil and gas project which use pipes.

Our company will accept the product quality objection registration record, pass it to the Q345R pressure vessel steel sheet production unit and relevant departments, and timely coordinate the supervision of product Q345R pressure vessel steel sheet quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
