TumacoHow much is the price of I-beam per tonWhat is the difference between seasonal and seasonal maintenance

What are the uses of I-beam? Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time,TumacoAlloy pipe GH4145, and the waist is parallel to the roll axis.Tumaco,Speed up the construction progress: weld the mesh with reinforcement to allow the rapid construction of the project. The required laying of welded steel bars is provided, so concrete can be poured, steel cutting,TumacoHow much is 30 I-beam per meter, etc., and the arrangement can be strengthened. ？ saving construction time? The construction progress is greatly accelerated and the construction period is shortened.Stages needing attention in the production and manufacture of alloy tubesCesis,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'.Aiming at the connective tissue and texture produced in stainless steel plate Position and other crystal defects are generally removed by heat treatment processes such as quenching or quenching. The effect of quenching is to optimize the crystal, eliminate structural defects, reduce strength, improve plastic deformation, and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe,TumacoHow much is 50 galvanized pipe per meter, quenching machinery and equipment cannot be lacked. Therefore, the formulation of appropriate annealing process is a necessary condition to ensure that the alloy pipe mechanism meets the standard and the commodity does not crack. If the manufacturer in order to better one sidedness, reduce the product cost and reduce the quenching process, it will eventually lead to bad harm to the product quality.Heating surface tubes for low and medium pressure boilers (working pressure is generally not greater than MPA and working temperature is below ℃);

Some applications of I-beam: Operating conditionsAs shown in the name, I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination, generally :, which makes the outer flange thin and the inner flange thick. Therefore, the section characteristics of I-beam in the two main planes are very different, and it is difficult to give full play to the strength characteristics in application. Although the thickened I-beam has also appeared in the I-beam market, the structure of the I-beam has determined its torsional performance.Online consultation,GB No. I-beam is in height, in leg width and in waist thickness.Difference and application description between H-beam and I-beamThe 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.

Carburizing: carburizing is the process of penetrating carbon atoms into the surface layer of steel. It also makes the low-carbon steel workpiece have the surface layer of high-carbon steel and then after quenching and low-temperature tempering, Cold extrusion. This kind of processing method is more purposeful. Before the preparation of steel processing and extrusion molding the part of the workpiece can maintain the toughness and plasticity of low-carbon steel.Interpretation and observation, when the extrusion molding is used for mm diameter pipe fittings, the investment of machinery and equipment is less, so the raw material consumption is also very small, and the technology is relatively perfect. Once the tube size is increased, the cold extrusion method must have large cargo capacity and high-power machinery and equipment. Therefore the automatic control system will be upgraded.Installation of galvanized pipe and precautionsBecause the section size of ordinary I-beam and light I-beam is relatively large and narrow, the use of I-beam should be reasonably selected according to the mechanical properties, chemical properties, weldability and structural size of I-beam.Tumaco,The 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.→ wide flange and large lateral stiffness. Strong bending resistance.I-beam, also known as universal 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.
