The service temperature of high pressure seamless steel pipe is below 450℃, and the domestic pipes are mainly made of A572 grade 65 high strength steel, No.10 and No.20 carbon steel hot-rolled pipes or cold drawn pipes. High pressure seamless steel pipe is often used in high temperature and high pressure conditions. Under the action of high temperature flue gas and water vapor, the pipe will be oxidized and corroded. The steel pipe is required to have high endurance strength, high oxidation resistance and corrosion resistance, and good structure stability.
According to South Korea newsis reported on March 12, Korea iron and steel association statistics show that in February, South Korea's domestic A572 grade 65 high strength steel steel exports to 2.44 million tons, down 2.4 percent year on year, after January down 3 percent, the second consecutive month of decline. In the past three years, South Korea's steel exports have decreased year by year, from 31.67 million tons in 2017 to 30.44 million tons in 2018 and 30.38 million tons in 2019. Instead, South Korea's A572 grade 65 high strength steel steel imports increased last year. As China's economy slows and steel prices fall, Chinese steel is pouring into South Korea, analysts say.
Welded pipe, also known as welded steel pipe, refers to the steel pipe made of steel plate or strip steel after crimping and forming, with a fixed length of 6 meters. The production process of welded steel pipe is simple, the production efficiency is high, the varieties and specifications are diversified, and the equipment investment is less, but the general strength is lower than that of seamless steel pipe. A572 grade 65 high strength steel, Welded pipes have many uses and are almost ubiquitous in our lives. However, when choosing welded pipes, we must pay attention to performance and material characteristics.
