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,United States Virgin IslandsHow much is 110 galvanized pipe per meter, cold and corrosion prevention. In addition, the chemical raw material transmission pipeline has a wide indoor space.United States Virgin Islands, The zinc coating is thick, the crystallization is detailed, uniform and non porous, and the corrosion resistance is excellent;Stages needing attention in the production and manufacture of alloy tubesAsuncion-Mita,The specification of pass design I-beam is expressed in cm of waist width. For example, 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, I-beam can also adopt special rolling method.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, 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.As 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.

→ under the same section load the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.First, the two hole beam end space on the pier top shall be used to set the cast-in-situ transverse cantilever cantilever beam, on which the prefabricated micro bending plate shall be installed. The second is to erect prefabricated sidewalk beams in the cantilever part of the cantilever beam. The sidewalk beams of bridge openings on both sides are longer than the main beam, one end is supported on the cantilever beam of side pier, and the other end is supported on the special buttress on the embankment, which is to avoid widening the abutment.I-beam,United States Virgin IslandsPrice of 1Cr5Mo alloy pipe, whether ordinary or light, can only be directly used for bending members or lattice members on its Web because of its large and narrow section size and large moment of inertia difference between the two main axes on the section. It is not suitable for axial compression members and flexural members perpendicular to the web plane, so its application range is very limited. I-beams are widely used in buildings and other metal structures.Recommendation and consultation,When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.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, IX and iy are not as good as H-section steel under the premise of equal weight.→ compared with general section steel it has the advantages of low cost, high precision and small residual stress. It does not need expensive welding materials and weld detection, and saves about % of the manufacturing cost of steel structure.

The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.Respect for customersXhy- 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,United States Virgin IslandsHow much is a meter of DN100 welded pipe, molybdenum, niobium, francium and other components. The alloy carbide formed has strong stability at high temperature. General carbon steel wire sleeve (GB / t- is a steel pipe used to protect wires in electrical installation projects such as industrial and civil buildings and installation of machinery and equipment.All the cracks occur at -mm away from the edge below the alloy pipe, and the macroeconomic orientation is vertical to the cold rolling orientation, showing a 'high mountain' shape.United States Virgin Islands,Difference and application description between H-beam and I-beamThe 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.I-beam, also known as universal beam
