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. 13CrMo44 steel material ASTM equivalent, 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 the morning of March 10th, according to the news conference of the Joint Prevention and Control Mechanism of the State Council, Deputy Director of the Emergency Management Department Shang Yong said that since the outbreak, 20,000 and 172,000 safety guidance groups have been organized nationwide, keeping a close eye on High-risk industries such as coal mines and non-coal mines inspected and guided 223,000 enterprises and rectified 168,000 hidden problems.

Superior process production line advantage sdf: The company has focused on weathering steel 13CrMo44 steel material ASTM equivalent, pressure vessel plate, oil tank plate, pipeline steel plates, and steel welded structures for many years, and has a strong factory scale; one of the domestic excellent weathering steel manufacturers, serving customers all over the world; using frequency conversion and microcomputer program control, the equipment is highly automated; Improve product efficiency and improve product quality.

Heat-resistant steel thick plate is made of heat-resistant steel and is processed by hot rolling. According to different structure characteristics, it can be divided into four types: austenitic type, ferrite type, martensite type and precipitation hardening type. 13CrMo44 steel material ASTM equivalent, The heat-resistant steel plate is widely used in the manufacture of petroleum, chemical equipment, boilers, steam turbines, industrial furnaces and other components and other components working at high temperatures.
