Methods of exerting efficiency in application of C-section steel→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.Escasu,Escasu12Cr1MoV alloy pipe,Galvanized pipe: the hot-dip galvanized pipe base plate and molten electroplating solution are combined physically and chemically to form a dense corrosion-resistant structure of zinc iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe substrate. Therefore, it has strong corrosion resistance.Alloy steel pipe is a new type of seamless steel pipe connection pipeline. The selection of pipeline connection pipeline, whether it is fire water system software, water supply equipment, or pipeline, heat and national defense industrial pipeline system software of petrochemical pipeline system, alloy steel pipe stimulates important effects.Mogoditshane,Carburizing: carburizing is the process of penetrating carbon atoms into the surface layer of steel. It also makes the low-carbon steel workpiece have the surface layer of high-carbon steel, and then after quenching and low-temperature tempering, the part of the workpiece can maintain the toughness and plasticity of low-carbon steel. 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.Plan option : Martensitic chromium alloy pipe

H-section steel is an economic section high-efficiency profile with more optimized section area distribution and more reasonable strength weight ratio. It is named because its section is the same as the English letter 'H'. There is no slope on the inner side of the two outer edges of H-section steel, which is straight. 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. Multi channel cold rolling (cold rolling) process. Cold rolling of steel pipe is carried out on multi roll mill. Stainless steel pipes are rolled with round holes composed of variable cross-section circular grooves and fixed taper.What are the uses of I-beam?Fair price→ compared with the concrete structure, reduce the self weight of the structure by % - %, and reduce the structural design internal force.When 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, mining and other industries to meet the provisions of cold, cold and corrosion prevention. In addition, the chemical raw material transmission pipeline has a wide indoor space.The shape of small longitudinal crack on the surface of alloy pipe is less than mm The overall width is less than mm The depth is lower than .mm.

Mixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.Potential development,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.Special shaped pipe: square pipe, rectangular pipe, cap pipe, steel pipe for hollow rubber steel doors and windows welded by general carbon structure steel and Mn steel strip, mainly used as agricultural machinery components, steel windows and doors, etc.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.Escasu,In order to make the steel pipe workpiece have the required mechanical,EscasuHow much is 40 cm I-beam per meter, 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, magnesium, physical and chemical properties through heat treatment to obtain different service properties.C-section steel has uniform zinc layer smooth surface, strong adhesion, no zinc scar, no zinc leakage and high dimensional accuracy. All surfaces are wrapped by zinc layer, and the zinc content on the surface is usually -g /? It has long service life, corrosion resistance and durability. It is a kind of stronger protection.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, such stainless steel plate can be applied.
