Our company has normalized CCS grade E bulk vessels steel strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high quality. It has a Class D (Class I and Class II pressure vessel) manufacturing license, and has passed the China Beijing Quality Center GB/T19001-2000 -ISO9001: 2000 quality certification. We can also supply normalized CCS grade E bulk vessels steel deep processing service for products normalized CCS grade E bulk vessels steel like cutting, drilling, bending, welding and grinding.
BBN Steel Company adheres to the marketing concept of "first-class technology, first-class steel quality, and first-class logistics services". It is our goal to build high-quality carbon steel normalized CCS grade E bulk vessels steel, alloy steel plates and high-strength structural steel plate international-class boutique bases. Our logistic team will make customs clearance documents, track products production process, and update shipping information for customers. Creating value for customers is our pursuit.
The preparation of normalized CCS grade E bulk vessels steel galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for normalized CCS grade E bulk vessels steel centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
In 2018, one of our India customers visit Zhengzhou office building and work shop to discuss carbon steel Q235B grind plate technical request. They have strict surface and thickness tolerance, and they also request UT and MT for testing for Q235B grind plate. As a result, they purchase 179 tons as trial order for first cooperation. After using the gind plate, the India customer has good comment on our normalized CCS grade E bulk vessels steel quality. Till now, we keep exporting around 100 tons per month as regularly.
For Q235 steel, Q represents the yield limit of this material, and the following 235 refers to the yield value of Q235 steel, which is about 235 MPa. The normalized CCS grade E bulk vessels steel, Q235 steel yield strength decreases with the increase of the thickness of the material. The yield strength is 235 MPa when the plate thickness / diameter is ≤ 16mm; 225 MPa is the yield strength when the thickness is 16mm < plate thickness / diameter ≤ 40mm; 215 MPa is the yield strength when 40mm < plate thickness / diameter ≤ 60mm; 205 MPa is the yield strength when 60mm < plate thickness / diameter ≤ 100mm; 195 MPa when the plate thickness / diameter is ≤ 150mm; 195 MPa when the thickness / diameter is less than 150mm; and ≤ 200mm when the thickness / diameter is less than 150mm The yield strength is 185 MPa.
