Chemical corrosion and fracture of a “Hot” pipeline of an ammonia-synthesis column

Chemical corrosion and fracture of a “Hot” pipeline of an ammonia-synthesis column

We investigate the character of fracture of welded joints of a gas pipeline made of 18Kh3MV steel after passing the ammonia synthesis column. Hydrogen corrosion of welded joints and nitration that proceed under the action of high temperatures (up to 350[double dagger]C) and pressures (up to 32 MPa)...

Zusammenfassung:We investigate the character of fracture of welded joints of a gas pipeline made of 18Kh3MV steel after passing the ammonia synthesis column. Hydrogen corrosion of welded joints and nitration that proceed under the action of high temperatures (up to 350[double dagger]C) and pressures (up to 32 MPa) in mixtures of nitrogen with hydrogen and ammonia are important for fracture.
