High temperature of prefabricated directly buried insulating pipe steel steel knowledge description
For steel and steel for high temperature of prefabricated directly buried insulating pipe, quality is the most important first. Because tin bronze steel insulation direct-buried pipe lining applied for high temperature and high pressure steam, and if a pipe leak or substandard issues such as scrap, the loss will be very large, and there may be accidents. So we purchased steel GCr15 must focus on product quality, don't just covet cheap price, quality and price, high cost performance is good, not cheap on the line.
Direct buried steam pipe steel steel applied in the industry, and the 45th steel sleeve is more widely recognized and applied, following our recent construction of directly buried steam pipe steel steel construction process simple to talk about his own views.
