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.Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members. It is not suitable for axial compression members or members with bending perpendicular to the web plane,Generally in terms of strength, toughness and mechanical properties. There are many differences. Hot dip galvanized pipe: the coil formed by welding the square pipe with steel plate or steel strip is placed in the galvanized tank on the basis of the square pipe to form a series of chemical reactions on the square pipe. The production process of hot-dip galvanized steel pipe is simple, the production efficiency is very high, and there are many varieties and specifications. The demand for RHS by equipment and capital is very small,St. Peter lieuInconel 600 alloy pipe, which is suitable for the production of small galvanized steel pipe plants. However, the strength of steel is much lower than that of seamless steel pipe. It is mainly used for drying, redox method and characteristic table.Alloy pipe is a very important way and type of seamless steel pipe. Its use is relatively common. It is widely used in various engineering projects, house construction and building decoration. Its fracture will always be found in the production, manufacturing and key marketing of alloy pipe, That is, many stages of production and processing are not done well. Another is that the seasoning is not enough and the proportion of chemical molecules is wrong. There are all reasons.Ramble,I-beam features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V, and the macro hardness is - HRCBecause all parts of I-beam are arranged at right angles, simple construction, cost saving and light structural weight in all directions, and has been widely used. The inner and outer sides of the flange of the I-beam are parallel or close to parallel, and the end of the flange is at a right angle, so it is named parallel flange I-beam. The web thickness of I-beam is smaller than that of ordinary I-beam with the same height of web, and the flange width is larger than that of ordinary I-beam with the same height of web, so it is also named wide edge I-beam.With the development of steel structure buildings, only I-beam is not enough, that is, thickened I-beam, which is easy to lose stability for load-bearing columns.

Frame line crack When the mesh reinforcement on both sides of the beam is different,St. Peter lieuHow much is the current I-beam per ton, the reinforcement on both sides extends into the beam, and the reinforcement anchorage length is required. H-section steel is an economic section steel with better mechanical properties than I-section steel. It is named because its section shape is the same as the English letter 'H'. The flange of hot rolled H-beam is wider than that of I-beam, with large lateral stiffness and strong bending resistance. Under the same specification, H-beam is lighter than I-beam.Safety production, Cold extrusion. This kind of processing method is more purposeful. Before the preparation of steel processing and extrusion molding,St. Peter lieu18 I-beam price quotation, 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.→ under the same section load the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.I-beam is widely used in buildings or other metal structures.

I-beam is widely usedQuality risk, business licenseAlloy pipes can be used for heating (cooling) projects.Check whether the manufacturer&#;s qualification, organization code certificate, tax registration certificate, production and operation license and other qualification materials are complete. Look at the case, investigate the supplier&#;s performance and the projects served in the past. Whether there is a self built logistics fleet or not, choosing a service provider with a self built logistics fleet can reduce the transportation cost, and more importantly, ensure the timeliness of delivery. After sales service, whether there is a sound and reliable after-sales service guarantee system, and timely solve quality problems in arrival acceptance and subsequent use. Check whether the quality assurance materials such as product quality certificate, material specification and warranty are complete. Check the appearance of the welded pipe, the surface is smooth and flat, the weld is dense, without burr, oil stain, corrosion, extrusion deformation and flat cross section. Use a micrometer to check whether the outer diameter and wall thickness of the welded pipe meet the requirements, and the standard wall thickness deviation shall not exceed % - %. NDT shall be carried out for welded pipe with flaw detector. Conduct bending tensile strength test according to the requirements, and there is no crack at the bend.The general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe, 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.St. Peter lieu, The defects can be removed by grinding with sand wheel, 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.
