What is the BBNSteel s355j2w+n density quotation

The company specializes in the research and development, production and sales of s355j2w+n density seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has s355j2w+n density five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,s355j2w+n density rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

Our company's technical department is the core department of the whole company. There are a group of very professional technical personnel. They provide some architectural drawings according to the ideas of customers, and they are responsible for how to select the right materials. Including the evaluation of steel products such as multi steel plate, s355j2w+n density and steel pipe, grasp the whole production process, and strictly follow the production standards and customer quality requirements.

The weight of seamless steel pipe is only 1 / 5 of that of square steel. Seamless steel pipe corrosion resistance acid, alkali, salt and atmospheric environment corrosion, high temperature resistance, good impact and fatigue resistance, do not need regular maintenance. The effective service life of product s355j2w+n density more than 15 years.

Expression method of pressure coefficient of seamless steel pipe: pressure P < 7MPa coefficient S-8 7 < s355j2w+n density 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 s355j2w+n density product packaging.
