Hot rolled S355J2 carbon steel plate sheet manufacturer

16Mo3 steel plate is used for pressure vessel, and it is EN10028-2 designated chromium molybdenum steel alloy that is used for increasing working temperature. 16Mo3 steel plate is used to make industrial boilers and pressure vessels for the petroleum, natural gas and chemical industries. 16Mo3 steel plate is different from other raw materials in welding: S355J2 carbon steel plate sheet preheating shall be carried out first, and the weld joint shall be kept for about 30 minutes after the completion of welding.

The company attaches great importance to systematic management, and has passed the S355J2 carbon steel plate sheet ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on S355J2 carbon steel plate sheet quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.

Expression method of pressure coefficient of seamless steel pipe: pressure P < 7MPa coefficient S-8 7 < S355J2 carbon steel plate sheet steel pipe pressure P < 17.5, coefficient 5-6 pressure P > 17.5, coefficient S-4 seamless pipe production and manufacturing: tube blank -- Inspection -- peeling -- Inspection -- Heating -- perforation -- pickling -- grinding -- lubrication and air drying -- welding head -- cold drawing -- solution treatment -- pickling -- pickling and passivation -- Inspection -- cold rolling -- degreasing -- air drying -- internal polishing -- one external polishing -- Inspection -- identification of finished S355J2 carbon steel plate sheet product packaging.

Due to the existence of this dense oxide film, the infiltration of oxygen and water into the steel matrix in the atmosphere is prevented, the development of corrosion into steel material is slowed down, and the atmospheric corrosion resistance of steel material is greatly improved. S355J2 carbon steel plate sheet, Weathering steel is a kind of steel system which can be used thinly, exposed or simply painted, and make products resistant to corrosion, prolong life, save labor and reduce consumption, upgrade and replace.

Our company has established and constantly improved the customer service system and emergency response system.
