H-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange, and the second is that the inner surface of the flange has no inclination, and the upper and lower surfaces are parallel. The section characteristics of H-beam are obviously better than those of traditional I-beam, channel steel and angle steel.Because the section size of ordinary I-beam and light I-beam is relatively large and narrow, the moment of inertia of the two main shafts on the section is quite different, which limits its application range. I-beam shall be selected according to the requirements of design drawings. In the structural design the use of I-beam should be reasonably selected according to the mechanical properties, weldability and structural size of I-beam.Rama chemical properties, Spiral seam high-frequency welded steel pipe (sy- for pressure fluid transportation is a spiral seam high-frequency welded steel pipe used for pressure fluid transportation which takes hot-rolled steel strip as pipe blank, often warm spiral forming and high-frequency lap welding method. The steel pipe has strong pressure bearing capacity and good plasticity, the application is safe and reliable, the diameter of steel pipe is large, the transportation efficiency is high, and the investment in laying pipeline can be saved. It is mainly used for laying pipelines for transporting oil, natural gas, Hot stamping. Fix the plan product workpiece or preformed vacancy on the rotating journal, with the wheel working pressure vacancy, radial wheel. After one or several solutions, there can also be a variety of methods for the whole process of hollow thick wall rotating body products. Products manufactured by high-precision processing method have excellent physical properties specification scope, mold shell and software requirements, which are very simple, very easy to be replaced,RamaReinforcement turning and blanking, and relatively low product cost. The processing time is not long enough, the processing capacity is not high, the total length of processing pipeline is limited, and the size of machinery and equipment is generally short.I-beam features: the content of chromium carbon alloy is -%,Rama304 seamless pipe wholesale, the hardness of chromium carbide alloy is V, and the macro hardness is - HRCThe 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.

Hot stamping. Fix the plan product workpiece or preformed vacancy on the rotating journal, with the wheel working pressure vacancy, radial wheel. After one or several solutions, there can also be a variety of methods for the whole process of hollow thick wall rotating body products. Products manufactured by high-precision processing method have excellent physical properties, specification scope, mold shell and software requirements, which are very simple, very easy to be replaced, and relatively low product cost. The processing time is not long enough, the processing capacity is not high, the total length of processing pipeline is limited, and the size of machinery and equipment is generally short.Due to the impact of poor visual . Only through the application of mesh and the overall stiffness can we see the potential of demand. The application of steel data is a high one, such as the reuse rate of mesh and reinforcement installed in the current mesh production company and the treatment of corrosion. The design strength value of circular reinforcement and the design strength value of welded reinforcement mesh. According to the equal strength substitution principle and considering comprehensive factors, the use of steel welded mesh plate can save the use of steel bars in the steel welded mesh plate factory. And the reinforcement mesh needs to be processed after it is shipped to the site, so there is no wear.Introduction to product knowledge of alloy pipe:Project scope,What should we pay attention to in the production of alloy pipeAiming at the connective tissue and texture produced in stainless steel plate Position and other crystal defects are generally removed by heat treatment processes such as quenching or quenching. The effect of quenching is to optimize the crystal, eliminate structural defects, reduce strength, improve plastic deformation, and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe, quenching machinery and equipment cannot be lacked. Therefore, the formulation of appropriate annealing process is a necessary condition to ensure that the alloy pipe mechanism meets the standard and the commodity does not crack. If the manufacturer in order to better one sidedness, reduce the product cost and reduce the quenching process, it will eventually lead to bad harm to the product quality.The crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width, the more serious the disadvantages.

Plan scheme : for high carbon steel with carbon content of more than .% and high chromium alloy pipe with chromium content of no less than %, the interval is min.OK or not?,According to the theory of steel structure,RamaHow much is 110 galvanized pipe per meter, the I-beam flange should be stressed, the I-beam should be standing rather than lying down.Idler pipe: it is used for electric welding steel pipe of idler of belt conveyor. It is generally made of Q, QA, B steel and steel, with a diameter of -mm. There are certain requirements for pipe tortuosity, water pressure and flattening tests are carried out.What are the requirements for alloy pipe construction accessoriesRama,Using alloy pipe to produce ring parts can improve the utilization rate of raw materials, simplify the production and manufacturing process, and save raw materials and production and processing construction time, such as roller bearing ring throwing Nowadays, seamless steel pipe has been widely used to produce hydraulic jack sleeve.I-beam is divided into ordinary I-beam and light I-beam. The specification of hot rolled ordinary I-beam is -#. The specification of hot-rolled flexible I-beam supplied through agreement between the supplier and the buyer is -#. I-beam is mainly used in building structure, vehicle manufacturing, other industrial structures and fixed panels and cabinets. I-beam is often used together with I-beam.Some applications of I-beam:
