Why target shooting
Thread Content
Why does the medium-pressure steam pipeline of the catalytic unit need to be targeted? ? ? ? ? ? ? ? ? ? ?
The main purpose of target shooting for medium-pressure steam pipelines is to remove welding slag, welding beads and other impurities in the pipeline through high-speed airflow to ensure that the medium-pressure steam will not be damaged by these impurities during use. Determine whether the shooting is finished based on the marks on the target board.
The welding slag and other impurities in the pipeline are brought out through high-speed airflow to ensure that the steam turbine will not be damaged or destroyed by these impurities when using medium-pressure steam.

Catalytic medium-pressure steam is mainly used as the power medium of steam turbines and must reach a certain degree of cleanliness, otherwise the blades will be damaged. Impurities are divided into two categories: One type is welding slag, welding flash and other debris during the construction process, and the other type is the oxide scale formed by exposure to the air during transportation. The best way to check whether the purge is qualified is to perform target purge and observe the degree of damage to the target.
passing by, learning* Well, it turns out that target shooting is not just for fun, right?
The main purpose is to sweep out all the welding slag and stolen goods in the pipelines
Haha, this guy is so funny!
Judge the purging status of the pipeline based on the traces of target shooting.
Thank you. Do you have any new ones?
Target shooting is a judgment method. It judges the purging condition of the medium-pressure steam pipeline by the number of target marks per square centimeter on the target piece! The purpose of target practice is to clean away welding slag, rust and other impurities in the medium-pressure steam pipeline!
