    Under the action of thermal stress, because the initial temperature of the surface layer is lower than that of the heart and the shrinkage is greater than that of the heart, the heart is pulled. At the end of cooling, because the final cooling volume shrinkage of the heart cannot be carried out freely, the surface layer is compressed and the heart is pulled. That is under the action of thermal stress, the surface of the workpiece is finally compressed and the center is pulled. This phenomenon is affected by factors such as cooling rate, material composition and heat treatment process. The faster the cooling rate, the higher the carbon content and alloy composition, the greater the uneven plastic deformation caused by thermal stress during cooling, and the greater the final residual stress. On the other hand, due to the change of microstructure during heat treatment, i.e. the transformation from austenite to martensite, and each part of workpiece will undergo phase transformation successively, resulting in inconsistent volume growth and structural stress. The final result of the change of tissue stress is the tensile stress on the surface and the compressive stress in the center, which is just opposite to the thermal stress. The microstructure stress is related to the cooling rate, shape and chemical composition of the workpiece in the martensitic transformation zone.Installation material list, whether it is fire water system software, water supply equipment or pipeline, heat and national defense industrial pipeline system software of petrochemical pipeline system,MalayerWhat software is there for steel bar turning, alloy steel pipe stimulates important effects.The advantage of the reinforcement mesh system is ecological.

    I-beam has the dual properties of high hardness and toughness materials. Compared with other engineering wear-resistant materials in China, such as various alloy steel plates, cast wear-resistant plates, cast stones,AmirGH536 alloy pipe, rubber, polyurethane, etc., it has irreplaceable comprehensive excellent properties.Due to the impact of poor visual . Only through the application of mesh and the overall stiffness can we see the potential of demand. The application of steel data is a high one, such as the reuse rate of mesh and reinforcement installed in the current mesh production company and the treatment of corrosion. The design strength value of circular reinforcement and the design strength value of welded reinforcement mesh. According to the equal strength substitution principle and considering comprehensive factors, the use of steel welded mesh plate can save the use of steel bars in the steel welded mesh plate factory. And the reinforcement mesh needs to be processed after it is shipped to the site, so there is no wear.→ wide flange and large lateral stiffness. Strong bending resistance.resources,Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, so it can only be directly used for members bent in the plane of their web or form lattice stressed members.

    Aiming at the connective tissue and texture produced in stainless steel plate Position and other crystal defects are generally removed by heat treatment processes such as quenching or quenching. The effect of quenching is to optimize the crystal eliminate structural defects, reduce strength, improve plastic deformation, and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe, quenching machinery and equipment cannot be lacked. Therefore, the formulation of appropriate annealing process is a necessary condition to ensure that the alloy pipe mechanism meets the standard and the commodity does not crack. If the manufacturer in order to better one sidedness, reduce the product cost and reduce the quenching process, it will eventually lead to bad harm to the product quality.Function of I-beam: where is I-beam mainly used?Sirjan ,There are many types of galvanized pipes, mainly including cold plated seamless pipes and hot-plated seamless pipes. But now the previous one is no longer used. The hot-dip seamless tube is still in use. Hot dip galvanized pipe is mainly used for steel pipes with low pressure fluid such as water and gas. When in use, if in normal working environment, the thickness of galvanized layer of hot-dip galvanized seamless steel pipe is up to μ M above and it has been used safely for about years. It can be seen that its service life is very long. Of course, when purchasing, we should also find regular manufacturers to order. Only in this way can we achieve this service life. As long as the galvanized pipe is cleaned after pickling, electro galvanizing will not be used. There are also some small enterprises in the market. They will use electro galvanizing in production. In this way, although it is much cheaper in price. However, the quality is very good when used, and it is also easy to have problems.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.Naryn,Sirjan 13CrMo44 alloy pipe,It is a potential rolled strip steel with rectangular section for general purpose. It is very common on construction sites. Its specifications are expressed in thickness and width. At present, most of the flat steel on the market are finished steel, ladders,Sirjan Will reinforced concrete rise or fall in 2021, bridges and fences. Flat steel can also be used as blank for welding rigid steel and slab for laminated thin plate.I-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, thin web and light weight. Wide flange I-beam, also known as H-beam, 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, physical and chemical properties, in addition to the reasonable selection of materials and forming processes, heat treatment process is often essential. Steel is the most widely used material in the mechanical industry. The microstructure of steel is complex and can be controlled by heat treatment. Therefore the heat treatment of steel is the main content of metal heat treatment. In addition, copper aluminum, magnesium, titanium and their alloys can also change their mechanical, physical and chemical properties through heat treatment to obtain different service properties.

    → compared with the concrete structure, the I-steel structure can increase the service area by %, reduce the self weight of the structure by % - %, and reduce the structural design internal force.The whole structure is composed of zinc and quaternary crystals, which effectively prevents the penetration of corrosion factors. From the point of view of the strong zinc corrosion resistance of the barrier layer, when the zinc sacrificial anode is at the forefront of protection, the scratches and scratches of some coatings and the insolubility of zinc oxide layer play a protective and blocking role.Because the section size of ordinary I-beam and light I-beam is relatively large and narrow, the moment of inertia of the two main shafts on the section is quite different, which limits its application range. I-beam shall be selected according to the requirements of design drawings. In the structural design, the use of I-beam should be reasonably selected according to the mechanical properties, chemical properties, weldability and structural size of I-beam.Create brilliance,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.Alloy pipes are widely used in building materials, and the test standards of alloy pipes are also different. Alloy pipe has high hardness and can be used at many levels, most of which is prestressed reinforcement. Where plastic deformation is not specified but compressive strength is specified, such stainless steel plate can be applied. 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, 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.

    Aiming at the connective tissue and texture produced in stainless steel plate Position and other crystal defects are generally removed by heat treatment processes such as quenching or quenching. The effect of quenching is to optimize the crystal, reduce strength, improve plastic deformation, and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe, quenching machinery and equipment cannot be lacked. Therefore,ShirazHow much is welded pipe 219, the formulation of appropriate annealing process is a necessary condition to ensure that the alloy pipe mechanism meets the standard and the commodity does not crack. If the manufacturer in order to better one sidedness, reduce the product cost and reduce the quenching process, it will eventually lead to bad harm to the product quality.The flange of H-beam is of equal thickness, including rolling section and combined section composed of three plates welded. All I-beams are rolled sections. Due to poor production technology, the inner edge of the flange has a slope of : The rolling of H-beam is different from that of ordinary I-beam. Only one set of horizontal rolls is used. Because its flange is wide and has no inclination (or the inclination is very small), a group of vertical rolls must be added for rolling at the same time. Therefore, its rolling process and equipment are more complex than ordinary rolling mills. The maximum height of rolled H-section steel that can be produced in China is mm, which exceeds the welded composite section.Shiraz,Galvanized pipe, also known as galvanized pipe, the coating is uniform, the adhesion is strong and the service life is long. The electroplating cost is low, the surface is not smooth, and the corrosion resistance is worse than that of hot dip galvanized pipe.Alloy pipe is a spiral seam seamless steel pipe which is made of hot-rolled strip steel coil, often processed by warm extrusion and welded by automatic double wire double side arc welding process. The alloy pipe sends the hot-rolled strip steel to the welded pipe unit, and the hot-rolled strip steel is extruded through multiple passes. The hot-rolled strip steel is rolled slowly to produce annular pipe material with open mouth gap. Adjust the reduction amount of the extrusion roll to control the welding gap at ~ mm and make both sides of the weld flush.Lelydorp, Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time, because the initial temperature of the surface layer is lower than that of the heart and the shrinkage is greater than that of the heart the heart is pulled. At the end of cooling, because the final cooling volume shrinkage of the heart cannot be carried out freely the surface layer is compressed and the heart is pulled. That is,ShirazHow many tons of reinforcement per square meter, under the action of thermal stress, the surface of the workpiece is finally compressed and the center is pulled. This phenomenon is affected by factors such as cooling rate, material composition and heat treatment process. The faster the cooling rate, the higher the carbon content and alloy composition, the greater the uneven plastic deformation caused by thermal stress during cooling, and the greater the final residual stress. On the other hand, due to the change of microstructure during heat treatment, i.e. the transformation from austenite to martensite, the increase of specific volume will be accompanied by the expansion of workpiece volume, and each part of workpiece will undergo phase transformation successively, resulting in inconsistent volume growth and structural stress. The final result of the change of tissue stress is the tensile stress on the surface and the compressive stress in the center, which is just opposite to the thermal stress. The microstructure stress is related to the cooling rate, shape and chemical composition of the workpiece in the martensitic transformation zone.After determining the reasonable pickling agent and polishing solution, it is very easy to carry out hot galvanizing for relevant alloy pipes. Use 'phosphating treatment' to degrease the pipes of electrolytic machine equipment, put them into the aqueous solution with zinc salt after pickling and passivation, connect the negative level of electrolytic machine equipment put them into the cold-rolled steel plate in the direction corresponding to the pipes, and connect the switching power supply, If the current flows from the positive stage to the negative stage, a layer of zinc is deposited in the pipe.

This makes the welding and splicing of H-section steel simpler than I-section steel, better mechanical properties per unit weight, and can save a lot of materials and construction time.→ wide flange and large lateral stiffness. Strong bending resistance.Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption, not occupy the natural environment, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation,IsfahanReinforcement material list, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.

    The flange of H-beam is of equal thickness including rolling section and combined section composed of three plates welded. All I-beams are rolled sections. Due to poor production technology, the inner edge of the flange has a slope of : The rolling of H-beam is different from that of ordinary I-beam. Only one set of horizontal rolls is used. Because its flange is wide and has no inclination (or the inclination is very small), a group of vertical rolls must be added for rolling at the same time. Therefore, its rolling process and equipment are more complex than ordinary rolling mills. The maximum height of rolled H-section steel that can be produced in China is mm, which exceeds the welded composite section. Spiral seam high-frequency welded steel pipe (sy- for general low-pressure fluid transportation takes hot-rolled steel strip coil as pipe blank and is often spiral formed at warm temperature. High frequency lap welding method is selected for welding spiral seam high-frequency welded steel pipe for general low-pressure fluid transportation. Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason, the special rolling method can be used to make full use of the skills of uneven deformation and pass design. For example, when the billet section is narrow and wide I-beam is required to be rolled, the wave rolling method can be used; for example, when the billet is wide and small I-beam is required to be rolled, the negative rolling method can be used Spread rolling, etc.management, it is very easy to carry out hot galvanizing for relevant alloy pipes. Use 'phosphating treatment' to degrease the pipes of electrolytic machine equipment, put them into the aqueous solution with zinc salt after pickling and passivation, put them into the cold-rolled steel plate in the direction corresponding to the pipes, and connect the switching power supply, If the current flows from the positive stage to the negative stage, a layer of zinc is deposited in the pipe.I-beamWhen it is used for ground heating and hot spring transportation, it can meet the requirements of refrigeration and achieve the practical effect of less damage. It is applicable to water conservancy engineering, cold and corrosion prevention. In addition, the chemical raw material transmission pipeline has a wide indoor space.

    Frame line crackProduct survey, Remove defective pipes within the allowable length.Filling: welded pipe is welded by electric welding of hot-rolled strip steel, so its influence was not as high as that of seamless steel pipe.Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption, not occupy the natural environment,Isfahan09CrCuSb alloy pipe, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation,Isfahan6. How many kilograms per meter of sub welded pipe, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.Isfahan,Whether I-section steel is ordinary or light, due to the relatively high and narrow section size there is a large difference in the moment of inertia between the two main sleeves of the section. Therefore, which makes it very limited in the scope of application.All the cracks occur at -mm away from the edge below the alloy pipe it can only be directly used for members bent in the plane of their web or form lattice stress members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, and the macroeconomic orientation is vertical to the cold rolling orientation, showing a 'high mountain' shape.Heating surface pipes, economizers, superheaters, reheaters, pipes for petrochemical industry, etc. for high-pressure boilers (working pressure is generally above MPa and working temperature is between ℃ ~ ℃)
