The performance requirements of S690 steel

Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.

At present, the design of oil and gas S690 steel pipeline is based on the yield strength of steel, and high transmission work requires higher yield strength of S690 steel steel. For welded wire pipe, the yield strength decreases after rolling and decreases with the increase of strength.

BBN Group's first blast furnace blast dehumidification system: The project started construction on May 2 and began trial operation on August 28. All data are balanced and stable, blast furnace output indicators have improved significantly, and the daily dehydration capacity of the two blast furnaces is as high as 124 tons, with a daily increase of about 200 tons S690 steel, and the blast furnace is running smoothly.
