What material is used for the ammonia pump outlet pipeline, and what are the requirements for welding after cracks occur?
20# steel is sufficient; in the event of cracks, thorough grinding, welding, and flaw detection are required.
Are there 16Mn materials used for ammonia pump pipelines?
The 16Mn material may have poor resistance to ammonia stress corrosion. 20# steel should be used, and welding must be carried out in strict accordance with welding standards; remember that radiographic testing must show satisfactory results
I want to know how to handle it during welding?
Made of 20# steel, passed radiographic and dye penetrant inspection! ! ! ! ! ! Radiation source location due to wall thickness requires preparation in advance! ! ! ! ! !
