Chemical corrosion and fracture of a “Hot” pipeline of an ammonia-synthesis column
摘要:
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 degreesC) and pressures (up to 32 MPa) in mixtures of nitrogen with hydrogen and ammonia are important for fracture.
