Because the section size of ordinary I-beam and light I-beam is relatively large and narrow, the moment of inertia of the two main shafts on the section is quite different, the use of I-beam should be reasonably selected according to the mechanical properties, chemical properties weldability and structural size of I-beam.The shape of small longitudinal crack on the surface of alloy pipe is less than mm The overall width is less than mm The depth is lower than .mm.kelowna ,The use of hot dip galvanizing has expanded with the development of industry and agriculture. Therefore, petroleum processing, marine exploration, metal structure, power transportation, shipbuilding, etc.), agriculture (such as sprinkler irrigation, heating room), construction (such as water and gas transportation, wire casing, scaffold, house, etc.), bridges, transportation, etc. because hot-dip galvanized productsI-beam is divided into ordinary I-beam and light I-beam. The specification of hot rolled ordinary I-beam is -#. The specification of hot-rolled flexible I-beam supplied through agreement between the supplier and the buyer is -#. I-beam is mainly used in building structure, vehicle manufacturing, other industrial structures and fixed panels and cabinets. I-beam is often used together with I-beam.Lausanne , 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,kelowna 1Cr5Mo high pressure alloy pipe, etc.The key purpose of grinding and polishing alloy pipe is to moisten the surface, and the relevant limit accuracy or appearance change is not easy to change.→ the two surfaces of the flange are parallel to each other making it easy to connect, process and install.
When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size. 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, medium and narrow flange I-beams.The 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,kelowna Price of 6m seamless pipe, there will be a rapid decline in the moving average of the apparent consumption of galvanized pipe, welded steel pipe and so on. The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.A complete range of products,The sodium cyanide passivation treatment of alloy pipe can be divided into four categories. Before passivation treatment, the surface of alloy pipe shall be clear of oil stains, pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned, 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. The defects can be removed by grinding with sand wheel, and can withstand forces in two directions.
The 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,target,I-beam is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.Relatively high stability and high deformation resistance. The mixture is usually composed of hard fine aggregate graded aggregate with high sand equivalent, especially micro seal and polymer modified seal, which greatly increases the strength and integrity of the pavement.Application characteristics of I-beamkelowna ,After the passivation treatment of alloy pipe,kelowna 25 how much is a ton of galvanized 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.Some applications of I-beam:Alloy tube is widely used in our daily life, which provides us with great assistance.
