Difference and application description between H-beam and I-beamAfter isothermal quenching treatment, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.Pachuka Steel mesh guardrail (steel mesh fence) steel mesh guardrail refers to the guardrail made of steel mesh. It is stronger and more durable than the guardrail made of electric welding mesh, steel mesh, hook mesh, etc., but its cost is much higher, and it is rarely used under normal circumstancesThe 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.Maun,H-section steel 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'. There is no slope on the inner side of the two outer edges of H-section steel, which is straight. This makes the welding and splicing of H-section steel simpler than I-section steel, better mechanical properties per unit weight, and can save a lot of materials and construction time.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.I-beam is mainly used in building structure, curtain wall engineering, especially in some construction sites. This product has the advantage of durability when used. It also has the characteristics of surface gloss, the cost of hot-dip galvanizing for rust prevention is lower than that of other paint coatings. In addition, this product also has the characteristics of no dripping,Pachuka16 I-beam price, strong adhesion, breaking the clean Legion and strong corrosion resistance. Even if it is used in some places where the environment is not good its service life is also very long, and it also has the characteristics of corrosion resistance. The standard anti rust thickness of hot-dip galvanizing can be maintained for more than years without repair. This is used in some suburban environments. However, in urban or offshore areas, standard urban or offshore areas can be maintained for years without repair. The products produced by our company must meet these requirements. Friends who need to order can call us directly.I-beam is widely usedTrustworthy,Application scope of alloy pipeAlloy tube is widely used in our daily life,PachukaMonel 400 alloy pipe, which provides us with great assistance.The wear resistance, fracture toughness, impact toughness and bending strength under different process conditions were compared, and then the heat treatment process of GCrMo was determined. Development and application of ZYS- bearing damping and antirust oil. Bearing is a new type of multial damping and antirust oil. It takes refined mineral oil as the base oil and is equipped with various additives such as antirust and antifriction. Through comparison test, matching test with lubricating grease and user test, it is proved that ZYS- bearing damping and antirust oil has outstanding damping effect and good antirust lubrication performance.
When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties,Pachuka2205 stainless steel seamless pipe manufacturer, weldability and structural size.Discount The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard. Pickling: if the material cannot be removed after cleaning, pickling will be selected. Pickling of galvanized pipe is divided into chemical and electrolytic. How to prevent white rust of galvanized seamless steel pipe? It has a certain anti-corrosion effect on the pipeline.Due to the relatively high and narrow section size of ordinary I-beam and light I-beam, the moment of inertia of the two main sleeves of the section is quite different, which makes it very limited in the scope of application. The use of I-beam shall be selected according to the requirements of design drawings.Pachuka,The section of I-beam has good straight pressure and tensile resistance, but the section size cannot resist torsion because the wing plate is too narrow. On the contrary, H steel has its own advantages and disadvantages.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. Judged as failing.
