Zhangui Nora18 #’s I-beamDo you know the specific role of

Key technical characteristics of alloy pipeAfter the passivation treatment of alloy pipe it is clearly proposed that water cleaning shall be carried out immediately after the aqueous solution, ~ times of water cleaning, and then chromic acid closed solution shall be carried out. Chromic acid solution must be carried out h after the subsequent water cleaning of metallographic structure and austenitic alloy pipe. Chromic acid aqueous solution (mass ratio) is % ~ %, the solution temperature is ~ ℃, and the solution time is min. Then dry.Zhangui Nora,Recently, the price of zinc has been falling continuously. The key reason lies in the soft skin of galvanized pipe consumption and the slow start of production and marketing rate of manufacturing industries in the middle and lower reaches after the Spring Festival. The disadvantage of zinc price has long been far beyond the level of cyclical factors. The main performance of no prosperity in the hot season is whether the market situation in the off peak season will become a more worried problem in the galvanized pipe sales market.Generally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.Fukui,Zhangui Nora16Mn high pressure alloy pipe,Determined by the shape, the section modulus, moment of inertia and corresponding strength of I-beam are obviously better than those of ordinary I-beam with the same single weight. When used in metal structures with different requirements, pressure load and eccentric load. Compared with ordinary I-beam, it can greatly improve the bearing capacity and save metal by % ~ %.Dehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlementAlloy 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.

When selecting I-beam in structural design, chemical properties, weldability and structural size.The first is people. Human factors are the control focus of welding. Therefore, before welding welders with skilled technology and welder certificate shall be selected for necessary technical training and disclosure. It shall not be replaced at will to ensure the relative stability of the welders welding the pipeline.When we carry out different projects, we must use different raw materials, which can ensure the quality of the project. In many kinds of data, alloy pipe is widely used. In many projects, we will apply it, so it is very popular in the field. When people carry out the construction of alloy pipe project, there are many things that must be paid special attention to. Let&#;s take you to know:Where is it,Introduction to product knowledge of alloy pipe:The specification of I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is cm. 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 ~ mm, expressed as No. ~ No., and the inclination of inner side wall of leg is : The pass system of rolled I-beam includes direct rolling pass system, cross rolling pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.I-beam, also known as steel beam, bearing performance and service life. This paper systematically introduces the development of high quality cold drawn bearing steel pipe and its application in bearing. Precision cold rolling of small and medium-sized bearing sleeves with bearing steel pipes can greatly improve material utilization, bearing performance and service life. This paper systematically introduces the service life of high quality cold drawn bearings.High quality and low price,It can withstand continuous moderate impact and can provide composite plates of various thicknessesWith the development of China&#;s infrastructure the investment in infrastructure continues to grow; Implement the strategy of western development. Economic construction has entered a new stage, and the demand for welded steel mesh for capital construction such as power,Zhangui NoraHow many inches is welded pipe 273, transportation, water conservancy, housing and municipal engineering will increase exponentially.The finished product has smooth surface, low friction coefficient, flatness error + / - mm / m length,Zhangui NoraGH3030 superalloy tube, wear resistance and maximum temperature of ℃Zhangui Nora, 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, with large lateral stiffness and strong bending resistance. Under the same specification, H-beam is lighter than I-beam.H-section steel Peak crack
