Classification introduction→ the two surfaces of the flange are parallel to each other, making it easy to connect, process and install.St. Thomas,Most of the original bridge decks lack a stable and solid base course with poor integrity. It is necessary to clear the original bridge deck, excavate part of the gravel cushion (if it is non gravel filler, and then pave cement stabilized gravel base course on which reinforced concrete bridge deck is poured. The longitudinal reinforcement and transverse reinforcement of the reinforcement mesh of the bridge deck pavement form a network structure, so it has good bonding and anchorage with the concrete,St. ThomasHow much is DN50 galvanized pipe per meter, and the load can be evenly dispersed which obviously improves the performance of the reinforced concrete structure. According to the practice test, the welded reinforcement mesh laid on the road can reduce the occurrence of cracks than the manual binding mesh. Hot push hole diameter. More sensitive applications and facilities of such methods require simplicity, low cost, easy maintenance, durable economic development and convenient product specification transformation. For example, the production of large diameter must be grooved pipe, elbow and similar products. You only need to add some spare parts. The expansion method of hot push can be used to process and manufacture large-diameter, thick wall and thin alloy steel pipes, and can not exceed the working capacity of thick wall pipes of machinery and equipment.Moinesti,d. All machines and equipment in a production line can connect with the software of the computer data collection system to complete the timely transmission of data information, and the performance parameters in the production process are monitored by the central control room.What are the requirements for alloy pipe construction accessoriesI-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 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.

The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.The surface of cold galvanized layer is smooth, dense and uniform. It has good mechanical properties and corrosion resistance. The consumption of hot-dip galvanized coating is between % - %. The galvanizing process is complex, but the thickness of single-sided coating, surface coating and double-sided coating is different, so the thin-walled pipe shall be galvanized. The zinc coating has strong protection and corrosion resistance.Some applications of I-beam:resources, Mixed pass system. According to the characteristics of rolling mills and products, in order to give full play to the advantages of their respective systems and overcome their disadvantages, mixed pass system is often adopted, that is, the combination of more than two systems. For example, straight leg cross rolling pass system is adopted for finished hole and front hole of finished product, etc.Patented manufacturing process of I-beam: I-beam has become a new industrial standard for wear-resistant materialsa. In the forming process, small internal stress and no scratch on the surface. The alloy pipe produced and processed has higher coordination ability in the scope of size specification and model of diameter and wall thickness, especially in the production and manufacturing of steel structure design grade thick wall pipe, especially medium diameter small thick wall pipe, which has incomparable advantages of other processing technologies, and can meet a large number of customer regulations on the specification and model of alloy pipe.

Main uses: as a finished material, flat steel can be used to make hoop iron, tools and mechanical parts, and used as building frame structural parts and escalators in buildings. Flat steel is divided into two types according to its shape: plane spring flat steel and single-sided double groove spring flat steel. Hot rolled spring flat steel is mainly used to manufacture leaf springs for automobiles, tractors, railway transportation and other machinery.new product,I-beam can be divided into four types according to shape: cold-formed equal edge I-beam, cold-formed unequal edge I-beam,St. Thomas25 welded pipe is more than one meter, cold-formed inner crimping I-beam and cold-formed outer crimping I-beam.Why are galvanized pipes so good?I-beam is widely used in buildings or other metal structures.St. Thomas,Classification introduction Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason, the special rolling method can be used to make full use of the skills of uneven deformation and pass design. For example, when the billet section is narrow and wide I-beam is required to be rolled,St. Thomas60 seamless pipe price, the wave rolling method can be used; for example, when the billet is wide and small I-beam is required to be rolled, the negative rolling method can be used Spread rolling, etc.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.
