When selecting I-beam in structural design,St. Thomas20 alloy pipe, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.The high-temperature passivation treatment of alloy pipe is to obtain the passivation treatment film by heating in the heat treatment equipment. Before passivation treatment, the surface layer of parts must be removed to remove waste. At a higher temperature, the passivation treatment film can be obtained according to the transformation temperature and time. The hue of passivation treatment film can refer to the annealing color of alloy pipe, and the main parameters of ambient temperature and time of heat treatment process can be selected.St. Thomas, Straight seam electric welding steel pipe (yb- is a steel pipe whose weld is longitudinally parallel to the steel pipe. It is usually divided into metric welded steel pipe welded thin-walled pipe, transformer cooling oil pipe, etc.The finished product has smooth surface, low friction coefficient, flatness error + / - mm / m length, wear resistance and maximum temperature of ℃Nkawkaw,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,St. ThomasC276 seamless pipe manufacturer, put them into the cold-rolled steel plate in the direction corresponding to the pipes, and connect the switching power supply, a layer of zinc is deposited in the pipe.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, 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, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.Passivation treatment operation of alloy pipe

Alloy pipes can be used for heating (cooling) projects. Seismic and cracking performance the longitudinal and transverse bars of the welded reinforcement mesh form a network structure, so it has good bonding and anchorage with the concrete, and the load can be evenly distributed, which obviously shows the seismic cracking performance of the reinforced concrete structure. According to the actual test, the welded reinforcement mesh laid on the road can reduce the occurrence of cracks than the manual binding mesh. It greatly reduces the unnecessary cost generated manually in the construction and shortens the construction period. The use of reinforcement mesh is simple and convenient, and the reinforcement mesh is convenient for transportation.Plan scheme : for high carbon steel with carbon content of more than .% and high chromium alloy pipe with chromium content of no less than %, the interval is min.where,What is the stainless steel passivation of alloy pipe?I-beam features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V, and the macro hardness is - HRCThe crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width the more serious the disadvantages.

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.packing,Introduction to product knowledge of alloy pipe:In addition to these, the advantages of galvanized pipe are also reflected in some other aspects. For example, its reliability is also very good. Because the combination of zinc coating and steel is good news for metallurgy, it has become a part of galvanized steel pipe on the steel surface. In this way, the durability of its coating is more reliable. And when the zinc coating forms a special metallurgical structure, this structure can withstand mechanical damage during transportation and use. When in use, it also has the advantages of multiple protection. Because every part of the product can be plated with zinc, even in depressions, sharp corners and hidden places can be protected in many ways. It is very convenient during construction. It really saves time and effort. It is because of so many advantages that the utilization rate of this product is very high. And it can avoid the time required for painting on the site after installation. If you want to purchase on your occasion,St. Thomas32 how much is a galvanized pipe, remember to go to the manufacturer, so that the price will be more favorable.I-beam also known as steel 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 is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.St. Thomas, house construction and building decoration. Its fracture will always be found in the production, manufacturing and key marketing of alloy pipe, 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.The specification of pass design I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is. The types of I-beam include hot-rolled ordinary I-beam, expressed as No. ~ No., and the inclination of inner wall of leg is : The pass system of rolled I-beam includes direct pass system, cross pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.Performance parameters and application scope of I-beam
