Superbti is a professional company supplying high performance titanium bars, wire, plates, forgings, tubes and fasteners.

The chimney corrosion is an important engineering design and manufacturing facilities of thermal power plant, the design data of foreign chimney, FGD chimney the structure form the sleeve type and multiple form, and the steel tube multiple tube chimney, brick in multiple cylinder structure.

For the steel tube structure in wet flue gas desulfurization under the condition of international industrial chimney Association released its "Model Code For Standard Specification for steel chimney Steel Chimneys" proposed in the medial adding a very thin layer of titanium alloy sheet or plate of corrosion by ordinary carbon steel plate. The brick tube material, the bearing structure system, and put forward the high requirements of brick and mortar, which must be clinker and potassium silicate acid acid clay masonry special, generally divided into two layers of staggered arrangement, and a sealing layer. Comparing the above two structures, it can be found that the material of the steel inner cylinder has good impermeability and sealing property, good corrosion resistance and high cost. Long life, while brick cylinder material one-time investment is less, but corrosion resistance, impermeability, structural properties are less than steel cylinder, short life, annual maintenance costs are very high.
