Defects of alloy pipe and solutions: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.San Pedro sacartepex,Reinforcement mesh is manufactured by automatic and intelligent production line under the strict quality control of the factory. Grid size, reinforcement specification and quality are strictly controlled. The longitudinal and transverse bars of the reinforcement mesh form a network structure, so it has good bonding and anchorage with the concrete, and the load is evenly distributed, which obviously shows the seismic crack resistance of the reinforced concrete structure.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,San Pedro sacartepexHow much is 50 galvanized pipe, 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.Mostar,I-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows: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.Alloy tube is widely used in our daily life, welders shall be trained, tested and qualified. In addition to the basic theory, the welder should consider the operation skills. The pipe welding process may include several postures of overhead welding, vertical welding and overhead welding (when the pipe cannot rotate). The size of current should be selected to take into account the formation of vertical welding and overhead welding (some pipes are not very large, and the current cannot be adjusted in the middle of one formation). In the process, the stability and formation of arc should be controlled, It can swing properly, and the forming shall be well combined with the necessary swing. 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.Process inspectionBecause all parts of I-beam are arranged at right angles, I-beam has the advantages of strong bending resistance, cost saving and light structural weight in all directions, and the end of the flange is at a right angle,San Pedro sacartepexHow much is No. 14 I-beam, and the flange width is larger than that of ordinary I-beam with the same height of web, so it is also named wide edge I-beam.Classification introductionWhat is the stainless steel passivation of alloy pipe?
I-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows:Recommendation and consultation, 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,San Pedro sacartepexHow much is a 6 meter galvanized pipe, with large lateral stiffness and strong bending resistance. Under the same specification, H-beam is lighter than I-beam.The correct and reasonable use of galvanized pipe can play a better role. The product can be widely used in the market because of its obvious performance advantages. Both strength and toughness are worth our choice. Let&#;s see what the specific uses are and what the acceptance standards are?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.San Pedro sacartepex,H-shaped steel groove is deep and thick, and can withstand forces in two directions.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.Some applications of I-beam:
