With the fast development in Myanmar, Myanmar navy build frigate every year. We Cooperate with Myanmar Navy from 2015. They purchased 412 ton LR AH36 steel plate from us as trial order in 2015. After receiving the ABS D32 container ships steel goods, they speak highly of the quality and our service. After that they purchase the shipbuilding steel plate from us regularly. In May,2018, the Myanmar navy's local representative visit our office and production line, and sign another contract 2025 ton steel order in our office.
The difference between ABS D32 container ships steel, hot rolled sheet and cold rolled sheet: hot rolled sheet has low hardness, easy processing and good ductility. The cold-rolled sheet has high hardness and relatively difficult processing, but it is not easy to deform and has high strength. The cold rolled sheet is mostly used in automobile manufacturing and electrical products. Therefore, the two have their own characteristics. According to these characteristics, it is more appropriate to choose the right rolled plate to maximize its effect and benefit.
After extrusion, the ABS D32 container ships steel tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.
