Five types of annealing methods in the steel pipe
1. Fully annealed Process: Heat the steel to 20~30℃ above Ac3, cool it slowly (with the furnace) after holding it for some time to obtain a heat treatment process (complete austenitization) close to the equilibrium structure. Complete annealing is mainly used for hypereutectoi...Read more -
What are the detection methods of oil casings
1. Ultrasonic detection When the ultrasonic wave is spread in the detected raw material, the acoustic properties of the raw material and the transformation of the internal tissue will have a positive effect on the spread of the ultrasonic wave. After detecting the level and co...Read more -
