Application of stainless steel reducer

　　The metallurgical and power industries need to consume a large number of metal pipelines every year to transport pulverized coal, ash slag, slurry, lime gypsum slurry, etc. Using ceramic composite pipe to replace other pipes has the characteristics of high wear resistance, long service life, convenient installation and remarkable economic benefits.

　　2. Application in mining and coal industry

　　(1) Mine: the pipeline is seriously worn by mine filling, concentrate powder and tailings transportation. In the past, the service life of mineral powder transportation pipeline such as Panzhihua and Daye Mine is less than one year. Changing this pipe can increase the service life by about 5 times.

　　(2) Coal: wet transportation is widely used for coal preparation and long-distance pipeline coal transportation. The transportation pipe is required to be wear-resistant and corrosion-resistant. The pipe can be used as a long-life transportation pipe with considerable economic benefits.

　　Connection mode and principle of stainless steel reducer: there are many connection modes of stainless steel large and small heads. The common modes are compression type, compression type, union type, push type and socket welding type, union flange connection, welding type and welding traditional connection, welding type and derivative series connection mode combining welding and traditional connection. Generally, in construction machinery, large tee has the characteristics of large diameter, thin wall, poor rigidity, smooth and beautiful appearance. Buckling forming method: three methods are commonly used. One method is called stretching method and the other is called stamping method. There are 3-4 rollers, two fixed rollers and one commissioning roller to debug the fixed roller distance. The finished pipe fittings are buckled. Other substances that cause transparency problems include semiconductor silicon, gallium arsenide, some coatings, some optical materials such as silver chloride, sapphire, quartz, sodium chloride, germanium and many special crystal products.
