Welded steel pipes are made by crimping steel plates, bending them into a circle, and then welding the joints together. Seamless steel pipe is directly processed by round steel piercing or hot rolling process, so there is no weld on the outer surface. The performance of seamless steel pipe is better than that of welded steel pipe, and the price of seamless steel pipe is also higher. There are some differences in chemical composition between A709 grade 100 bridge steel plate, welded steel pipe and seamless steel pipe. The material of welded steel pipe contains the chemical composition suitable for welding.
In the first quarter of 2020, the output of EU steel pipe industry decreased by 13.3% year-on-year, but it is considered to be flexible due to its close connection with the A709 grade 100 bridge steel plate construction industry. However, demand for large welded pipes is expected to remain weak in the oil and gas industry. In 2020, the steel consumption of steel pipe industry will account for 13% of EU A709 grade 100 bridge steel plate steel consumption market. Uestf predicts that in 2020, the output of steel pipe industry will continue the downward trend of 2019, with a year-on-year decrease of 19.4%, and a rebound of 9.8% in 2021.
The tight supply of coal in Bohai Rim ports has eased, but high-calorie and low-sulfur coal is still in short supply; port resources are tight, traders are reluctant to sell at low prices, and the sentiment remains strong. Although the coal storage of key power plants is relatively high, the coal storage of coastal power plants is in the middle, and the enthusiasm for pulling transportation still exists. As the weather gradually turns colder, downstream power consumption increases, procurement demand continues to increase, and power plants release demand.
