Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, A514 Gr E structural steel material based on a high starting point and high technology, the company has vigorously developed various steel products A514 Gr E structural steel material and deep-processed parts, steel structures, precision castings, seamless pipes.
According to the market forecast released by Eurofer on August 5, the output of all A514 Gr E structural steel material steel consumption industries in the European Union will drop by 12.8% in 2020, and rise by 8.9% in 2021. However, the European Union said that the government's "awesome strength" support will reduce the A514 Gr E structural steel material steel consumption intensity in the construction industry significantly less than other industries.
At present, the design of oil and gas A514 Gr E structural steel material pipeline is based on the yield strength of steel, and high transmission work requires higher yield strength of A514 Gr E structural steel material steel. For welded wire pipe, the yield strength decreases after rolling and decreases with the increase of strength.
The yield point of the steel structure determines the stress that the structure can withstand without permanent deformation. The minimum yield point of typical carbon structural steel is 235MPa. The minimum yield point of typical low-alloy high-strength steel is 345MPa. Therefore, according to the proportional relationship of its yield point, the use of low-alloy high-strength steel allows the stress to be 1.4 times higher than that of carbon structural steel. Compared with A514 Gr E structural steel material, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.
The company's headquarters has a well-established logistics distribution system, which can quickly transport the steel materials to the port through the contracted logistics companies. Professional contracted logistics companies can significantly reduce costs and various commodity-related expenses. Meanwhile, the flexible transfer ensures that the A514 Gr E structural steel material steel materials can be shipped immediately after passing the quality inspection.
