1.Steel Pipes, Steel Tubes

Steel Pipes are not only used for conveying fluid and powdery solids, exchanging heat energy, making mechanical parts and containers, but also a kind of economic steel. There are many kinds of steel pipes, which can be divided into seamless steel pipe and welded pipe. Steel pipes are widely used.The use of steel pipe to make building structure net frame, pillar and mechanical support can reduce weight, save 20 ~ 40% of metal, and realize mechanized construction of factory. The use of steel pipe to make highway bridges can not only save steel and simplify construction, but also greatly reduce the area of coating protection layer, save investment and maintenance cost. The variety specifications of steel tube products are very various, and their performance requirements are also various. All of these should be distinguished with changes in user requirements or working conditions.

Seamless Steel Tube

Seamless steel pipe is widely used. The general purpose seamless steel pipe is produced by ordinary carbon structural steel, low alloy structural steel or alloy structural steel. The output is the largest, and is mainly used for conveying fluid pipes or structural parts.

Seamless steel pipe has a hollow section, a large number of pipes used for conveying fluid, such as pipelines, such as oil, natural gas, gas, water and some solid materials. Widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold with steel pipe manufacturing circular parts, can improve the utilization rate of materials, simplify the manufacturing process, material saving and working hours, has been widely used to manufacture steel tube.

2.Incoloy 926 Characteristic:

Metallurgical structure: 926 is face-centered cubic lattice structure.

Corrosion resistance
926 is an austenitic stainless steel alloy has a similar chemical composition with 904L alloy, its nitrogen content is 0.2%, molybdenum content is 6.5%. Molybdenum and nitrogen content significantly increased the resistance of pitting and crevice corrosion in the halide media.Meantime, nickel and nitrogen not only ensures the stability of metallographical, but also reduce separating intergranular trend in the thermal process or welding process better than the nitrogen content of nickel alloy.

926 has particular corrosion resistance in the chloride ions medium due to the excellent local corrosion resistance and 25% nickel alloy content.A variety of experiments in the 10000-70000ppm of Chloride concentration, PH 5-6, 50-68℃ operating temperature of the slurry of limestone FGD system show that, afte years trial period, 926 without pitting and crevice corrosion.



926 in other chemical media also has good corrosion resistance in the high temperature and high concentration of media, including sulfuric acid, phosphoric acid, acid gas, sea water, salt and organic acids.926 is the material that choosed for BAM directory Chapter 6 of "dangerous goods storage and transportation containers norms" by Berlin, Germany's national Institute for Materials Research and Testing (BAM) . In addition, in order to have the best corrosion resistance only when the material is in the right state of metallurgy and guarantee clean conditions.
