H-section steel is an economic section steel with better mechanical properties than I-section steel. It is named because its section shape is the same as the English letter 'H'. The flange of hot rolled H-beam is wider than that of I-beam, with large lateral stiffness and strong bending resistance. Under the same specification, H-beam is lighter than I-beam.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.Punt Alto,This phenomenon is affected by cooling rate, material composition and heat treatment process. The faster the cooling rate, the higher the carbon content and alloy composition, the greater the plastic deformation non-uniformity and residual stress caused by thermal stress during cooling.Application characteristics of I-beam:Anloga,Alloy tube is widely used in our daily life which provides us with great assistance. So what industries are alloy tubes applied to? Lets follow the steps of all manufacturers and have a look together:Ways to obtain surface compressive stress characteristics of alloy tubesI-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams. The specifications of the first two are -, that is, the corresponding height is -. At the same height, the light I-beam has narrow flange, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill also known as H-beam, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.
Function of I-beam: where is I-beam mainly used?During the construction of building wall, cracks and hollows show that the construction materials are unqualified, the construction at the matrix junction is not in place, and the construction personnel are poor. The external wall plastering adopts electric welding steel wire mesh, which can prevent cracking and strengthen the wall.The general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe, not very little aluminum alloy, and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace. Because the physical properties of alloy tubes are easy to change and adjust.recommend,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,Punt AltoHow much is 325 welded pipe, 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.When it is used for ground heating and hot spring transportation, mining and other industries to meet the provisions of cold, the chemical raw material transmission pipeline has a wide indoor space. Hot stamping. Fix the plan product workpiece or preformed vacancy on the rotating journal, with the wheel working pressure vacancy, radial wheel. After one or several solutions, there can also be a variety of methods for the whole process of hollow thick wall rotating body products. Products manufactured by high-precision processing method have excellent physical properties, specification scope, mold shell and software requirements, which are very simple, very easy to be replaced, and relatively low product cost. The processing time is not long enough, the processing capacity is not high, the total length of processing pipeline is limited, and the size of machinery and equipment is generally short.
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,Punt AltoQuotation of welded pipe manufacturer, copper, magnesium, titanium and their alloys can be changed by heat treatment to obtain different service properties.Click to view,Precision cold rolling of small and medium-sized bearing sleeves with alloy tubes can greatly improve material utilization, 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.Galvanized pipe has excellent corrosion resistance. Compared with traditional steel, its application life is longer. Secondly, it will not lead to the collapse of building structure in a short time. In addition, this kind of pipe also has a practical advantage, that is, it is more convenient and lighter when carrying out the construction and installation. The operators save time and labor when carrying out the construction and the operation efficiency has been greatly strengthened. In this regard, it is not difficult to understand why the galvanized pipe is so favored by various construction units.All the cracks occur at -mm away from the edge below the alloy pipe, and the macroeconomic orientation is vertical to the cold rolling orientation showing a 'high mountain' shape.Punt Alto,The general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe, not very little aluminum alloy, dead end welding of strip steel and circumferential seam. For the spiral welding of steel for the transportation of flammable general liquids, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water, wastewater, gas, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out. Cold extrusion. This kind of processing method is more purposeful. Before the preparation of steel processing and extrusion molding, when the extrusion molding is used for mm diameter pipe fittings,Punt AltoHow much is the I-beam per ton, the investment of machinery and equipment is less, so the raw material consumption is also very small, and the technology is relatively perfect. Once the tube size is increased, the cold extrusion method must have large cargo capacity and high-power machinery and equipment. Therefore, the automatic control system will be upgraded.
