When selecting I-beam in structural design, chemical properties, weldability and structural size.Generally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.Symbiosis with the sea,Symbiosis with the seaHow much is I-beam per meter,The whole structure is composed of zinc and quaternary crystals, forming dense crystals and barrier layer on the plate, which effectively prevents the penetration of corrosion factors. From the point of view of the strong zinc corrosion resistance of the barrier layer, when the zinc sacrificial anode is at the forefront of protection, the scratches and scratches of some coatings and the insolubility of zinc oxide layer play a protective and blocking role.→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.Lida,The shape of I-beam is similar to that of H-beam. What is the difference between them?I-beam 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'.Application characteristics of I-beam:

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. Completion of pipeline trench ground; Bricklaying of pipe shaft is completed.Determined by the shape,Symbiosis with the seaHow much is a meter of 2-inch galvanized pipe, it shows its superior performance in bearing bending moment, pressure load and eccentric load. Compared with ordinary I-beam it can greatly improve the bearing capacity and save metal by % ~ %.Encyclopedic knowledge,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, light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~, expressed as No. ~ No.,Symbiosis with the seaHow much is the price of 75 galvanized pipe, 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.Due to the unique performance of I-beam, I-beam has successfully solved the problem of serious equipment wear in many industries.

Alloy pipe can be divided into round steel pipe and special-shaped steel according to different cross-sectional area. Because the circular area is large on the premise of the same side length a large amount of liquid can be transported with an annular tube. In addition, when the circular cross section bears the internal or external axial working pressure, the bearing force is more symmetrical. Therefore, most seamless steel pipes are round steel pipes.High quality brand,I-beam Material requirements Peak crackSymbiosis with the sea,At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.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.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.
