According to the national standard of hot rolled H-section steel in China (GB / t-, H-section steel is divided into narrow flange, wide flange and steel pile whose codes are Hz, HK and Hu respectively. Narrow flange H-section steel is suitable for beams or compression bending members while wide flange H-section steel and H-section steel piles are suitable for axial compression members or compression bending members. Compared with H-section steel, W, not very little aluminum alloy, and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace. Because the physical properties of alloy tubes are easy to change and adjust.Sean fugos,During the construction of building wall, cracks and hollows show that the construction materials are unqualified, the construction at the matrix junction is not in place, and the construction personnel are poor. The external wall plastering adopts electric welding steel wire mesh, which can prevent cracking and strengthen the wall.Xhy- series high hardness alloy I-beam; Undertake drawings and process wear-resistant pipes（ Φ ≥mm）； Undertake the processing and production of vulnerable parts of cement machinery; Welding technology consultation and service; The wear-resistant layer of alloy wear-resistant plate of high chromium heap welding flux cored wire series is mainly high chromium, as well as manganese, molybdenum, niobium, francium and other components. The alloy carbide formed has strong stability at high temperature.Beroroha,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.Key technical characteristics of alloy pipeI-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 specifications of the first two are -, that is, the corresponding height is -. At the same height, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.

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, and the waist is parallel to the roll axis. Steel pipe with complex section -- unequal hexagonal steel pipe, five petal quincunx steel pipe, double convex steel pipe, double concave steel pipe, conical steel pipe, corrugated steel pipe, watch case steel pipe and others.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.Honesty is the foundation,Methods of exerting efficiency in application of C-section steel→ 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.At the same height, light I-beam has narrower legs, thinner waist and lighter weight than ordinary I-beam. No. - is large I-beam,Sean fugosReinforcement turning and blanking, and No. - is medium I-beam. Imported I-beam shall be marked with actual specifications, dimensions and relevant standards.

When it is used for ground heating and hot spring transportation, it can meet the requirements of refrigeration and achieve the practical effect of less damage. It is applicable to water conservancy engineering, mining and other industries to meet the provisions of cold, cold and corrosion prevention. In addition, the chemical raw material transmission pipeline has a wide indoor space.Service first,After isothermal quenching treatment, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment. Sulfur is a harmful impurity in steel. Steel with high sulfur content is easy to embrittle during pressure processing at high temperature, which is usually called thermal embrittlementX-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, dead end welding of strip steel and circumferential seam. For the spiral welding of steel for the transportation of flammable general liquids, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water, wastewater, gas, heating steam and other general liquids X-ray or ultrasonic testing sampling inspection (%) shall be carried out.Sean fugos,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.It is widely used in various fields of national economic construction, such as buildings, power stations, oil drilling platforms,Sean fugosHow much is a quarter galvanized pipe of six meters, vehicles, highways, steel structure plants and large warehousesThe 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.
