GB No. I-beam is in height, in leg width and in waist thickness.Defects of alloy pipe and solutions:San Rafael Ariba,Galvanized pipe,San Rafael AribaPrice of 12Cr1MoV alloy 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,San Rafael AribaHow much is one meter of I-beam, the surface is not smooth, and the corrosion resistance is worse than that of hot dip galvanized pipe.Carburizing: carburizing is the process of penetrating carbon atoms into the surface layer of steel. It also makes the low-carbon steel workpiece have the surface layer of high-carbon steel, and then after quenching and low-temperature tempering, the part of the workpiece can maintain the toughness and plasticity of low-carbon steel.North-Bay,H-shaped steel groove is deep and thick, and can withstand forces in two directions. Miscellaneous scabStages needing attention in the production and manufacture of alloy tubes

The wear resistance, fracture toughness, impact toughness and bending strength under different process conditions were compared, and then the heat treatment process of GCrMo was determined. Development and application of ZYS- bearing damping and antirust oil. Bearing is a new type of multial damping and antirust oil. It takes refined mineral oil as the base oil and is equipped with various additives such as antirust and antifriction. Through comparison test, matching test with lubricating grease and user test, it is proved that ZYS- bearing damping and antirust oil has outstanding damping effect and good antirust lubrication performance. The tensile strength of seamless pipe is more than ~ times that of ordinary steel the elastic coefficient is better than that of steel, and has good creep resistance, corrosion resistance and seismic resistance.Stages needing attention in the production and manufacture of alloy tubesplan,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.With the development of steel structure buildings, only I-beam is not enough that is, thickened I-beam,San Rafael Ariba25 how much is a meter of galvanized pipe, which is easy to lose stability for load-bearing columns.H-section steel

Classification introductionLatest consultation,Alloy pipes are widely used in building materials, and the test standards of alloy pipes are also different. Alloy pipe has high hardness and can be used at many levels, most of which is prestressed reinforcement. Where plastic deformation is not specified but compressive strength is specified, such stainless steel plate can be applied. The zinc coating is thick, the crystallization is detailed, and the corrosion resistance is excellent;After determining the reasonable pickling agent and polishing solution, it is very easy to carry out hot galvanizing for relevant alloy pipes. Use 'phosphating treatment' to degrease the pipes of electrolytic machine equipment, put them into the aqueous solution with zinc salt after pickling and passivation, put them into the cold-rolled steel plate in the direction corresponding to the pipes, and connect the switching power supply, If the current flows from the positive stage to the negative stage a layer of zinc is deposited in the pipe.San Rafael Ariba
