Difference and application description between H-beam and I-beamI-beam, also known as steel 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.Brental, The zinc layer obtained by electroplating is relatively pure, which corrodes slowly in acid, alkali and other fog, and can effectively maintain the steel matrix;Passivation treatment operation of alloy pipeAsenovgrad,Aiming 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,BrentalHow much is 50 galvanized pipe, 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. Small longitudinal crackb. The professional two-sided arc welding processing technology can complete the electric welding at a good position,BrentalHow much is a welded pipe meal, which is not easy to have the disadvantages of staggered joint, welding deviation and incomplete penetration, and it is very easy to manipulate the welding quality.

I-beam can only be used for beam, while H-beam can be used for load-bearing column of structure. Spiral seam submerged arc welded steel pipe (SY- for pressure fluid transportation is a spiral seam steel pipe used for pressure fluid transportation, which takes hot-rolled steel strip coil as pipe blank, often warm spiral forming and welded by double-sided submerged arc welding. The steel pipe has strong pressure bearing capacity and good welding . After various strict scientific inspections and tests, it is safe and reliable to use. The steel pipe has large diameter and high transportation efficiency, and can save the investment in laying pipelines. It is mainly used for transporting oil and natural gas.Precision cold rolling of small and medium-sized bearing sleeves with alloy tubes can greatly improve material utilization, bearing performance and service life. This paper systematically introduces the development of high quality cold drawn bearing steel pipe and its application in bearing. Precision cold rolling of small and medium-sized bearing sleeves with bearing steel pipes can greatly improve material utilization, bearing performance and service life. This paper systematically introduces the service life of high quality cold drawn bearings.A complete range of products,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, and more passes can be matched under the condition of a certain length of the roll body.I-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows:Generally, the process of pickling and passivation will be carried out for alloy pipes but the alloy pipes after pickling and passivation are very easy to rust. Therefore, dead end welding of strip steel and circumferential seam. For the spiral welding of steel for the transportation of flammable general liquids there is no harm to carry out hot galvanizing in the middle and later stage.

X-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water wastewater, gas, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.ranking,Dry processing technology: after passivation treatment, or drying treatment or air drying can be selected. . the straight length of the hook of the surface mesh reinforcement at the grid support shall not be less than mm, and the bending diameter shall not be less than D (D is the reinforcement diameter). Cross rolling pass system. This pass system refers to that the two open legs of the I-beam pass are not on the same side of the waist at the same time, and the waist has an included angle with the horizontal axis.Brental,Mixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.I-beam features: the content of chromium carbon alloy is -%, the hardness of chromium carbide alloy is V, and the macro hardness is - HRCI-beam: national standard * what is the wall thickness of I-beam
