The lower gas collection duct of the KeLLog type first-stage furnace in ammonia synthesis plants is made of INCOLOY800H; is domestic material used for this purpose?
Thread Content
I would like to ask the experts: are there any ammonia production plants that use domestic INCOLOY800H pipes as the downcomer pipes in the Kellog-type first-stage furnace? What is the quality of the next batch of gas collection pipe products?
There should still be no domestic production capable of replacing it
These past couple of days, I’ve heard from some installation manufacturers that Baosteel and Taiyuan Iron and Steel can produce it, and the quality is quite good. Is it true?
You should call Baosteel or Taiyuan Iron and Steel, and ask them to provide the test data for the materials they produce, as well as information on their properties. Whether the materials are domestic or imported, it is the data that matters.
There is a Japanese company in Jiangsu that produces products of good quality; I’ve forgotten its name. I used to buy products from them.
Thank you so much! I would also like to ask you: is the factory in Jiangsu you mentioned Jiangsu Biaoxin Kubota? Which factory are you from? Is the ammonia synthesis process Kellogg’s? Is the lower gas collection pipe made of Incoloy 800H? Is it manufactured domestically in Jiangsu by Kubota?
