Cement Mortar Lining Coating

 Cement mortar lining anti-corrosion steel pipe means deal with the inner of pipe with cement mortar of anticorrosive wear-resisting processing. Because there are lots of concrete in the Cement mortar lining anti-corrosion steel pipe, which can absorb lots of heat. When there’s a fire disaster, the cross profile temperature field distribution of tubular column is very uneven, this can extend the fire-resistant time of pipe, slow down the rate of temperature increase.Even if the steel pipe yielded,the concrete can bear most of axial load,prevent the structure fall down.This can also improve the fire resistance of composite beam,because the heat can transport from the top to the concrete,which can drop the temperature.Through the experimental statistical data,we can know that Cement mortar lining anti-corrosion steel pipe can endure the requirements of level 1 refractory 3 hours. compare with steel pipe,it can save 
1/3—2/3 of fireproof coating oreven more.With the increase of pipe diameter, the coating material can save more.We can use centrifugal machine or Piping sprayer to make a layer of cement coating in the inner of water transport steel pipe,in order to prolong the work life, protect the water quality, improve the water-carrying capacity of pipeline.
