YoheviLarge diameter high pressure alloy pipeType of choice

a. In the forming process, the thick steel plate has uniform deformation, small internal stress and no scratch on the surface. The alloy pipe produced and processed has higher coordination ability in the scope of size, specification and model of diameter and wall thickness, especially in the production and manufacturing of steel structure design grade thick wall pipe, especially medium diameter small thick wall pipe, which has incomparable advantages of other processing technologies, and can meet a large number of customer regulations on the specification and model of alloy pipe. The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.Yohevi,First, the two hole beam end space on the pier top shall be used to set the cast-in-situ transverse cantilever cantilever beam, on which the prefabricated micro bending plate shall be installed. The second is to erect prefabricated sidewalk beams in the cantilever part of the cantilever beam. The sidewalk beams of bridge openings on both sides are longer than the main beam, one end is supported on the cantilever beam of side pier, and the other end is supported on the special buttress on the embankment, which is to avoid widening the abutment.I-beam can only be used for beam, while H-beam can be used for load-bearing column of structure.OElgiy,The production process can be summarized as follows: pre leveling → finishing → straightening → post leveling. Flat steel / A / B steel with width of -, thickness of -, rectangular section and slightly pure edge. Flat steel can be finished steel, or it can be used as blank for welded pipe and thin slab for laminated thin plate.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. Hot push hole diameter. More sensitive applications and facilities of such methods require simplicity, low cost, easy maintenance, durable economic development and convenient product specification transformation. For example, the production of large diameter must be grooved pipe, elbow and similar products. You only need to add some spare parts. The expansion method of hot push can be used to process and manufacture large-diameter, thick wall and thin alloy steel pipes, and can not exceed the working capacity of thick wall pipes of machinery and equipment.

Key technical characteristics of alloy pipeThe monthly summary of the real estate industry shows that there is a significant positive correlation between the market sales and the long-term trend of the apparent consumption of galvanized pipe, but there will also be a backwardness of the market in a special stage, and after the backwardness of the market in stages, there will be a rapid decline in the moving average of the apparent consumption of galvanized pipe, welded steel pipe and so on.→ I-beam can be processed into T-beam and honeycomb beam can be combined to form various section forms, which greatly meets the needs of engineering design and manufacturing.Credit guarantee, 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, it shows its superior performance in bearing bending moment, pressure load and eccentric load. Compared with ordinary I-beam,YoheviA335 P11 alloy pipe, it can greatly improve the bearing capacity and save metal by % ~ %.I-beam: national standard * what is the wall thickness of I-beam

The sodium cyanide passivation treatment of alloy pipe can be divided into four categories. Before passivation treatment, pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned,YoheviHow many kilograms per meter of 150 welded pipe, and the workpiece of alloy pipe products can be infiltrated into aqueous solution. The passivation treatment of the alloy tube in sodium cyanide transforms the surface layer into a very thin passivation treatment film, which determines that the color of the surface layer has no change before and after passivation treatment, and the reproducibility of the solution is good.average method,→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.The correct and reasonable use of galvanized pipe can play a better role. The product can be widely used in the market because of its obvious performance advantages. Both strength and toughness are worth our choice. Let&#;s see what the specific uses are and what the acceptance standards are?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. 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.Yohevi,H-section steel belongs to high-efficiency and economic cutting profile (other cold-formed thin-wall section steel profiled steel plate, etc.). Due to the reasonable section shape they can make the steel give more play to its performance and improve the cutting capacity. Different from ordinary I-type, the flange of H-section steel is widened, so it is convenient to connect with other components with high-strength bolts. Its size composition is reasonable, series and models are complete, which is convenient for settingThe 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.Whether I-section steel is ordinary or light, 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 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.
