BP440 plate armored car, Steel pipes are widely used in our life, such as pipelines for transporting oil, natural gas, gas, water and some solid materials. Steel pipe can also be used to manufacture building structure grid, prop and mechanical support, which can reduce weight, save metal by 20-40%, and realize factory mechanized construction. For steel pipes on the market, in fact, there are seamless pipes and welded steel pipes. If not purchasing often, buyers will easily ignore their models and some material problems.

The company covers an area of 15,000 square meters and the plant construction area is 10,000 square meters. We have introduced more than 50 sets of advanced BP440 plate armored car production equipment, auxiliary equipment and testing equipment at home and abroad, more than 260 employees, more than 20 middle and senior management staff, more than 10 professional and technical personnel, annual production capacity of 100,000 tons. Main products: flat steel, BP440 plate armored car steel pipe, steel plate, section steel, steel structure processing parts, etc. We also accept incoming materials and annealing processing.

Blast furnace ironmaking is a traditional ironmaking method based on coke energy. It cooperates with converter steelmaking and is the main method of producing BP440 plate armored car steel at present. This dominance of blast furnace ironmaking is not expected to change for quite a long time. The essence of blast furnace ironmaking is the reduction of iron. Besides, coke is used as fuel and reducing agent. At high temperatures, iron ore or iron-containing raw materials are reduced from an oxide or mineral state to liquid pig iron.

The acicular ferrite pipeline steel can inhibit the formation of polygonal ferrite, promote the acicular ferrite transformation, and improve the precipitation strengthening effect of carbon and niobium nitride by adding molybdenum to reduce the transformation temperature of polygonal ferrite, so as to improve the strength of steel and reduce the ductile brittle transition temperature. The BP440 plate armored car, tempered sorbite pipeline steel adopts the heat treatment process of quenching and tempering. The tempered sorbite structure is formed to meet the comprehensive requirements of thick wall, high strength and sufficient toughness.

Our company will accept the product quality objection registration record, pass it to the BP440 plate armored car production unit and relevant departments, and timely coordinate the supervision of product BP440 plate armored car quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
