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 ℃ ~ ℃)Advantages of using I-beam: reduce maintenance cost, reduce downtime, improve equipment operation rate, reduce wear,Monday repurchaseHow much is a 12 cm I-beam, reduce equipment capacity and increase power consumptionMonday repurchase, When the end span plate is connected with the concrete beam for structural reinforcement, the length of the surface mesh reinforcement extending into the beam shall not be less than d. When the beam width is small, the extended reinforcement shall be bent . When the perimeter of the floor is poured integrally with the concrete beam or wall, the length of the surface mesh reinforcement extending into the beam shall not be less than the anchorage length of the small reinforcement required by the standard (without transverse reinforcement), when the beam width is small, the extended reinforcement shall be bent.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.Mexico,Whether I-section steel is ordinary or light,Monday repurchase12Cr1MoVG alloy pipe factory,Monday repurchaseHow much is a 30 cm I-beam, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.Advantages of using I-beam: reduce maintenance cost, reduce downtime, improve equipment operation rate, reduce wear, reduce equipment capacity and increase power consumptionIt 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, which can be used ready-made for components, ladders, bridges and fences. Flat steel can also be used as blank for welding rigid steel and slab for laminated thin plate.

H-section steel Spray is OK. This method can not only completely remove rust oxide and dirt, resulting in the average roughness of the welded pipe.The 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 but also the welded pipe will be affected by abrasive impact and friction, the more serious the disadvantages.Inspection standard,Application characteristics of I-beam:Introduction to product knowledge of alloy pipe:The core of C-section steel is the structural system of braced frame. More than half of such senior managers in China are the former. Unfavorable to earthquake resistance. Hydraulic power, and the power is large generally about KW, which is similar to the plate shearing and bending machine. The general control process is complex, and PLC control is mostly used.

Due to the relatively high and narrow section size of ordinary I-beam and light I-beam, the moment of inertia of the two main sleeves of the section is quite different, which makes it very limited in the scope of application. The use of I-beam shall be selected according to the requirements of design drawings.Inspection requirements,Generally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.Steel pipes can be classified by their models:Determined by the shape, the section modulus, pressure load and eccentric load. Compared with ordinary I-beam, it can greatly improve the bearing capacity and save metal by % ~ %.Monday repurchase,However, what we need to do now is to improve the production technology level of China&#;s production process of C-section steel, and step up the formulation of relevant industry standards and inspection standards. C-section steel manufacturers should keep close contact with truck manufacturers and communicate more. In this way, it is more conducive for C-section steel manufacturers to produce C-section steel products suitable for truck industry.The core of C-section steel is the structural system of braced frame. More than half of such senior managers in China are the former. Unfavorable to earthquake resistance. Hydraulic power, and the power is large, generally about KW, which is similar to the plate shearing and bending machine. The general control process is complex, and PLC control is mostly used.Defects of alloy pipe and solutions:
