Alloy pipe can be divided into round steel pipe and special-shaped steel according to different cross-sectional area. Because the circular area is large on the premise of the same side length, a large amount of liquid can be transported with an annular tube. In addition, when the circular cross section bears the internal or external axial working pressure, the bearing force is more symmetrical. Therefore, most seamless steel pipes are round steel pipes.H-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange, and the second is that the inner surface of the flange has no inclination, and the upper and lower surfaces are parallel. The section characteristics of H-beam are obviously better than those of traditional I-beam, channel steel and angle steel.Georgetown,Classification supplementStages needing attention in the production and manufacture of alloy tubesKhujaobod,I-beam is a long strip steel with groove section, which belongs to carbon structural steel for construction and machinery. It is a section steel with complex section and its section shape is groove shape. China&#;s imports of I-beams are greater than its exports. The main producing areas are Tangshan Iron and steel, Baotou Iron and steel, Shangang, huangte, Maanshan Iron and steel, Xuanhua Iron and steel, Japan iron and steel, etc.I-beam can only be used for beam while H-beam can be used for load-bearing column of structure.Whether I-section steel is ordinary or light,GeorgetownAlloy pipe, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.

Alloy pipe is a very important way and type of seamless steel pipe. Its use is relatively common. It is widely used in various engineering projects, house construction and building decoration. Its fracture will always be found in the production, manufacturing and key marketing of alloy pipe, That is, many stages of production and processing are not done well. Another is that the seasoning is not enough and the proportion of chemical molecules is wrong. There are all reasons. Simple section steel pipe -- circular steel pipe, square steel pipe, oval steel pipe, triangular steel pipe, rhombic steel pipe, semi-circular steel pipe,Georgetown40Cr small diameter seamless pipe, others.Alloy pipes can be used for heating (cooling) projects.management,Key technical characteristics of alloy pipe:Nitriding: also known as nitriding, it is the process of penetrating nitrogen atoms into the surface layer of steel. At present, bearing performance and service life. This paper systematically introduces the development of high quality cold drawn bearing steel pipe and its application in bearing. Precision cold rolling of small and medium-sized bearing sleeves with bearing steel pipes can greatly improve material utilization, bearing performance and service life. This paper systematically introduces the service life of high quality cold drawn bearings.

Some applications of I-beam:recommend, The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge. Material requirementsDue to the relatively high and narrow section size of ordinary I-beam and light I-beam, the moment of inertia of the two main axes of the section is quite different,GeorgetownPrice of reinforcement sleeve, which makes it very limited in the scope of application. The use of I-beam shall be selected according to the requirements of design drawings.Georgetown,Determined by the shape, the section modulus, moment of inertia and corresponding strength of I-beam are obviously better than those of ordinary I-beam with the same single weight. When used in metal structures with different requirements, it shows its superior performance in bearing bending moment pressure load and eccentric load. Compared with ordinary I-beam, it can greatly improve the bearing capacity and save metal by % ~ %.What is the purpose of flat steelI-beam is widely used in buildings or other metal structures.
