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,Classification supplementThe utility model has the advantages that the axial force of the roll is small, the axial movement is small, and the working slope is not required,Qibray,When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties,San Francisco demacorisQ345B longitudinal welded pipe factory, weldability and structural size.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.Generally, the process of pickling and passivation will be carried out for alloy pipes, but the alloy pipes after pickling and passivation are very easy to rust. Therefore, the way to find a solution to wiredrawing corrosion is 'grinding and polishing'. Due to grinding and polishing there is no harm to carry out hot galvanizing in the middle and later stage.

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,San Francisco demacorisGb9948 price of seamless pipe, 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, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.Installation of galvanized pipe and precautionsIt is often asked that the shape of I-beam is similar to that of H-beam. What is the difference between them? Many people can&#;t explain it in detail. Here is a detailed answer for you: many people think that I-beam is a domestic name and H-beam is a foreign name. In fact, this cognition is wrong. H-beam and I-beam are different in shape!Industry management, Peak crackWhether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members.

Peak crackCustomer first,When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.Filling: welded pipe is welded by electric welding of hot-rolled strip steel, as well as manganese, molybdenum, niobium,San Francisco demacorisAlloy pipe 12Cr1MoVG, francium and other components. The alloy carbide formed has strong stability at high temperature.San Francisco demacoris,I-beam is widely usedStages needing attention in the production and manufacture of alloy tubesWhen 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.
