I-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows:GB No. I-beam is in height, in leg width and in waist thickness.Steiner,During the heating and cooling process of structural welded pipe workpiece, due to the inconsistent cooling speed and time of surface layer and core layer the temperature difference will be formed,Steiner40CrNiMo alloy pipe,SteinerInconel 600 seamless pipe, resulting in uneven volume expansion and contraction resulting in stress, namely thermal stress. Under the action of thermal stress, the starting temperature of the surface layer is lower than that of the core layer, and the shrinkage is greater than that of the core layer, making the core layer stretch. At the end of cooling, under the action of thermal stress, the surface of the workpiece is compressed and the core is pulled.I-beam, also known as universal beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.Zhengzhou,The core of C-section steel is the structural system of braced frame. More than half of such senior managers in China are the former. Unfavorable to earthquake resistance. Hydraulic power, and the power is large, generally about KW, which is similar to the plate shearing and bending machine. The general control process is complex, and PLC control is mostly used.What is the stainless steel passivation of alloy pipe?I-beam features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V, and the macro hardness is - HRC

The utility model has the advantages that the axial force of the roll is small, the axial movement is small, the working inclined plane is not required the pass occupies a small length of the roll body, and more passes can be matched under the condition of a certain length of the roll body. Construction preparationThe pickling agent in the pickling process contains many acidic substances, including hydrochloric acid, sodium cyanide, etc., which has strong corrosion and reduction, and the temperature of etching substances is relatively high. Therefore, the corrosion resistance of alloy pipes is specified higher.Equipment maintenance,Using alloy pipe to produce ring parts can improve the utilization rate of raw materials, and save raw materials and production and processing construction time, such as roller bearing ring throwing Nowadays,SteinerWhat is the price of seamless pipe, seamless steel pipe has been widely used to produce hydraulic jack sleeve.Key technical characteristics of alloy pipe Remove defective pipes within the allowable length.

The wear resistance, fracture toughness, 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.Online consultation,Alloy steel pipe is a new type of seamless steel pipe connection pipeline. The selection of pipeline connection pipeline, whether it is fire water system software, water supply equipment, or pipeline, alloy steel pipe stimulates important effects.Acceptance according to standardsThe high-temperature passivation treatment of alloy pipe is to obtain the passivation treatment film by heating in the heat treatment equipment. Before passivation treatment, the surface layer of parts must be removed to remove waste. At a higher temperature, the passivation treatment film can be obtained according to the transformation temperature and time. The hue of passivation treatment film can refer to the annealing color of alloy pipe, and the main parameters of ambient temperature and time of heat treatment process can be selected.Steiner,→ 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 side length of I-beam is small and the height is large, so it can only bear the force in one direction.Alloy pipe can be divided into round steel pipe and special-shaped steel according to different cross-sectional area. Because the circular area is large on the premise of the same side length, a large amount of liquid can be transported with an annular tube. In addition, when the circular cross section bears the internal or external axial working pressure, the bearing force is more symmetrical. Therefore, most seamless steel pipes are round steel pipes.
