Welcome to BBN High Strength Steels Factory
At the same time of doing well in density of S690QL production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the density of S690QL technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.
As a leading international steel supplier, we have two warehouses, close to Tianjin port and Shanghai port. This superior geographical location effectively saves the domestic transportation cost and greatly improves our service level. At the same time, it also shortens our delivery time and provides more convenience for customers.
Converter steelmaking: The furnace body of the converter can be rotated, and the steel plate is used as the outer shell, and the refractory is used as the inner lining. Converter density of S690QL steelmaking does not require additional heating, because the molten iron is inherently high temperature, and it still continues to generate thermal oxidation reactions (from silicon, carbon and oxygen in molten iron).Because no more fuel is needed for heating, energy consumption is reduced.
This customer is a leading Engineering, Procurement and Construction company serving the Hydrocarbon and Chemical industries spanning Oil & Gas, Petrochemical, Refining, Fertilizer and related sectors in India. The A335 Grade P5 Steel Pipe and P9 density of S690QL Seamless Steel Pipe we supplied is for EIL refineries project.
