Before welding, preheat should be carried out according to the steel plate AH36 DH36 EH36 welding process, and set up a good temperature measuring point.The number and thickness of weld layers, as well as the temperature between weld layers, should be controlled.And after each welding, the corresponding heat preservation treatment should be carried out.After steel plate ah36 dh36 eh36 welding the weld, and after 24 hours, then you can carry out ultrasonic nondestructive testing, but the ambient temperature should be up to the standard.
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.
The outer diameter of the hot-rolled seamless pipe is generally larger than 32mm, and the wall thickness is 2.5-75mm. The diameter of the cold-rolled seamless pipe can be 6mm, the wall thickness can be 0.25mm, the outer diameter of the thin-walled pipe can be 5mm, and the wall thickness is less than 0.25mm. The size accuracy of the cold-rolled seamless pipe is higher than that of the hot-rolled seamless pipe, steel plate ah36 dh36 eh36.
