After determining the reasonable pickling agent and polishing solution, it is very easy to carry out hot galvanizing for relevant alloy pipes. Use 'phosphating treatment' to degrease the pipes of electrolytic machine equipment, put them into the aqueous solution with zinc salt after pickling and passivation, connect the negative level of electrolytic machine equipment, put them into the cold-rolled steel plate in the direction corresponding to the pipes, and connect the switching power supply, If the current flows from the positive stage to the negative stage, a layer of zinc is deposited in the pipe.What are the uses of I-beam?Tulamor, According to the process, it is divided into arc welded pipe, resistance welded pipe (high frequency and low frequency), gas welded pipe and furnace welded pipe. The defects can be removed by grinding with sand wheel,Its heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption, not occupy the natural environment, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment unique and convenient installation,TulamorHow much is 50 galvanized pipe per meter, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.At the same height, light I-beam has narrower legs, thinner waist and lighter weight than ordinary I-beam. No. - is large I-beam, and No. - is medium I-beam. Imported I-beam shall be marked with actual specifications, dimensions and relevant standards.So why is the alloy pipe easy to rust after being pickled and passivated by the software?

The utility model has the advantages that the axial force of the roll is small, the axial movement is small, the working inclined plane is not required, the pass occupies a small length of the roll body, and more passes can be matched under the condition of a certain length of the roll body. Spiral seam submerged arc welded steel pipe (SY- for pressure fluid transportation is a spiral seam steel pipe used for pressure fluid transportation, which takes hot-rolled steel strip coil as pipe blank, often warm spiral forming and welded by double-sided submerged arc welding. The steel pipe has strong pressure bearing capacity and good welding . After various strict scientific inspections and tests, it is safe and reliable to use. The steel pipe has large diameter and high transportation efficiency, and can save the investment in laying pipelines. It is mainly used for transporting oil and natural gas.It is a potential rolled strip steel with rectangular section for general purpose. It is very common on construction sites. Its specifications are expressed in thickness and width. At present, most of the flat steel on the market are finished steel, which can be used ready-made for components, ladders, bridges and fences. Flat steel can also be used as blank for welding rigid steel and slab for laminated thin plate.technical service,The working principle of flat steel finishing machine in I-beam production process is to pre level and finally level the cold flat steel with two groups of leveling wheel sets staggered up and down in the thickness direction; A pair of finishing wheels arranged relatively are used to extrude the width direction, so that the width is compressed to achieve the expected parameters, and the compression amount is adjustable; Straighten the width with staggered straightening wheels.→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.→ wide flange and large lateral stiffness. Strong bending resistance.

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., 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.original,Due to the unique performance of I-beam, I-beam has successfully solved the problem of serious equipment wear in many industries.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 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.The alloy tube can be hardened by induction heating, so it has excellent rolling fatigue characteristics and corrosion resistance. Therefore, this kind of steel has been widely used as the material of rolling mill flap ball screw in rolling mill manufacturers. In addition to the excellent properties of cronidur steel, and its application range is expected to be further expanded.Tulamor,I-beam also known as steel beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.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., 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, we must use different raw materials which can ensure the quality of the project. In many kinds of data,TulamorDN50 seamless pipe price, alloy pipe is widely used. In many projects, 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:
