The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.Tocoa, I-beam has successfully solved the problem of serious equipment wear in many industries.Santiago,Some applications of I-beam:Nitriding: also known as nitriding, it is the process of penetrating nitrogen atoms into the surface layer of steel. At present, gas nitriding is widely used in the production of alloy steel pipe.What are the requirements for alloy pipe construction accessories

According to the theory of steel structure, the I-beam flange should be stressed, that is, the I-beam should be standing rather than lying down.Spiral welded pipe: it is made by rolling low-carbon structural steel or low-alloy structural steel strip into pipe blank according to the viewpoint of certain spiral line (called forming angle) and then welding the pipe seam. It can produce large-diameter steel pipe with narrow strip steel. Spiral welded pipe is mainly used for oil and natural gas transportation pipeline,Tocoa40Cr alloy pipe manufacturer, and its standard is expressed by outer diameter * wall thickness. Spiral welded pipe has single-sided welding and double-sided welding. The welded pipe shall ensure that the hydrostatic test, tensile strength and cold bending of the weld meet the requirements. Cross rolling pass system. This pass system refers to that the two open legs of the I-beam pass are not on the same side of the waist at the same time, and the waist has an included angle with the horizontal axis.Quality risk,TocoaSuperalloy tube gh3039, I-beam has successfully solved the problem of serious equipment wear in many industries.I-beam, whether ordinary or light, can only be directly used for bending members or lattice members on its Web because of its large and narrow section size and large moment of inertia difference between the two main axes on the section. It is not suitable for axial compression members and flexural members perpendicular to the web plane, so its application range is very limited. I-beams are widely used in buildings and other metal structures.

Plan scheme : Martensitic chromium alloy pipe and chromium alloy pipe with Cr composition exceeding %, without high carbon steel and high chromium alloy pipe. The aqueous solution contains % sodium cyanide % ~ % (volume ratio) the solution temperature is ~ ℃, and the solution time is min.Honesty and mutual benefit,What are the uses of I-beam? Manganese: it can improve the strength of steel, weaken and eliminate the adverse effects of sulfur, and improve the hardenability of steel. High alloy steel (high manganese steel) with high manganese content has good wear resistance and other physical propertiesThe utility model has the advantages that the axial force of the roll is small, the axial movement is small, and the working slope is not required,Tocoa,Ways to obtain surface compressive stress characteristics of alloy tubesGB No. I-beam is in height,TocoaLarge diameter 15CrMoG alloy pipe, in leg width and in waist thickness.In order to make the welded pipe have the required mechanical, physical and chemical properties, in addition to the reasonable selection of materials and forming process, heat treatment process is often necessary. In addition, the mechanical, physical and chemical properties of aluminum, copper, magnesium, titanium and their alloys can be changed by heat treatment to obtain different service properties.
