I-beam is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.According to the theory of steel structure, the I-beam flange should be stressed, that is, the I-beam should be standing rather than lying down.Coconut,Coconut10# steel seamless pipe,Go all the way along the Tiegang overpass to wharf Near the lower bridge mouth, the reporter saw that a pump truck with an arm of meters was standing under the bridge spraying cement on the bridge deck, and more than a dozen workers were nervously carrying out leveling work. Small longitudinal crackVictoriaville, Small longitudinal crack Remove defective pipes within the allowable length.Classification introduction

The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.Compared with manual binding, welded steel mesh can reduce the occurrence of cracks by more than %. The use of reinforcement mesh can make the project construction faster. As long as the reinforcement mesh is laid as required, the concrete can be poured, eliminating the links of reinforcement on-site cutting,Coconut12Cr1MoVG high pressure alloy pipe, placing one by one and binding. It can save % - % of working hours, so it can only bear the force in one direction.quality index,Application characteristics of I-beamWhen selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties,Coconut40CrNiMo alloy pipe, weldability and structural size.What is the purpose of flat steel

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.Recommendation and consultation,Stages needing attention in the production and manufacture of alloy tubesGalvanized pipe, also known as galvanized pipe, is divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing layer is thick the coating is uniform, the adhesion is strong and the service life is long. The electroplating cost is low, the surface is not smooth, and the corrosion resistance is worse than that of hot dip galvanized pipe.When we carry out different projects, we must use different raw materials, which can ensure the quality of the project. In many kinds of data, alloy pipe is widely used. In many projects, we will apply it so it is very popular in the field. When people carry out the construction of alloy pipe project,I-beam→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.X-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, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.
