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. flat 50x10 S690QL, 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.

On October 30, the Ministry of Ecology and Environment issued the "Action Plan for Comprehensive Control of Air Pollution in the Yangtze River Delta Region in the Fall and Winter of 2020-2021". The "Plan" stated that the steel production capacity of Tianjin will be controlled at 15 million tons by the end of December 2020. Around this time, Hebei’s steel production capacity will be controlled within 200 million tons, and the elimination of 4.3-meter coke ovens with longer furnace age and poor furnace conditions will be accelerated, and independent coking companies will gradually withdraw.
