r-br: br- '', '' ' ',- Anti-corrosion steel pipe lined with cement mortar refers to the anti-corrosion and wear-resistant treatment of cement mortar inside the pipe body of the steel pipe. Anti-corrosion steel pipes lined with cement mortar are filled with concrete and can absorb a large amount of heat energy. Therefore, the temperature field of the cross-section of the pipe column is very unevenly distributed when exposed to fire, which increases the fire resistance time of the column and slows down the heating rate of the steel column. And once the steel columns yield, the concrete can bear most of the axial load, preventing the structure from collapsing. The fire resistance of composite beams also increases because the temperature of the steel beam is reduced by transferring heat from the top flange to the concrete. Experimental statistics show that: compared with steel columns, meeting the first-class fire resistance hour requirements can save fire retardant coatings /-/ or even more. As the diameter of the steel pipe increases, more coatings can be saved. Water transmission steel pipes are coated with cement on the inner wall of the steel pipe through a centrifuge or pipeline sprayer, which mainly extends the service life of the water supply pipeline, protects water quality, and improves the water transmission capacity of the pipeline.
