What is alloy steel pipe?
Alloy steel pipe is mainly used for high-pressure and high-temperature pipelines and equipment such as power plants, nuclear power, high-pressure boilers, high-temperature superheaters and reheaters. It is made of carbon steel, alloy structural steel and stainless heat-resistant steel, and is made by hot rolling (extrusion, expansion) or cold rolling (drawing). Alloy pipes have hollow cross-sections […]
Four major pipeline factory prefabricated bends
Four major pipelines: 1: Main steam pipeline (two high-temperature and high-pressure steam pipelines between the superheater outlet header and the high-pressure main steam valve interface); 2: Hot reheat steam pipeline (two high-temperature and high-pressure steam pipelines from the reheater outlet header to the medium-pressure main steam valve interface); 3: Cold reheat steam pipeline (two high-temperature […]
