The specification of pass design I-beam is expressed in cm of waist width. For example the waist width of No. I-beam is. The types of I-beam include hot-rolled ordinary I-beam, light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~, expressed as No. ~ No., and the inclination of inner wall of leg is : The pass system of rolled I-beam includes direct pass system, cross pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.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, heat and national defense industrial pipeline system software of petrochemical pipeline system, alloy steel pipe stimulates important effects.Borujerd,BorujerdA335p92 American standard high pressure alloy pipe,Galvanized pipes shall be stored in dustproof to keep clean and new . As a professional manufacturer of galvanized pipe, we have produced galvanized pipe products for many years. Welcome friends who need to buy. Miscellaneous scabAmarousion,GB No. I-beam is in height, in leg width and in waist thickness.It is a potential rolled strip steel with rectangular section for general purpose. It is very common on construction sites. Its specifications are expressed in thickness and width. At present, most of the flat steel on the market are finished steel, which can be used ready-made for components, ladders, bridges and fences. Flat steel can also be used as blank for welding rigid steel and slab for laminated thin plate.Welded steel pipes need to be processed through various processes before application. The heat treatment of welded steel pipes is a very important link in the processing of welded steel pipes. Hot working is a metal hot working process in which metal materials are heated, insulated and cooled in a certain medium, and their metal properties are controlled by changing the metallographic structure on the surface or inside of the material. During the heating and cooling process of structural welded steel pipe workpiece, due to the inconsistency of cooling speed and time between the surface and the core, the temperature difference will be formed, which will lead to uneven volume expansion and contraction and produce stress, that is, thermal stress.

Small longitudinal crackAccording to the section shape, the steel pipe is divided into:GB No. I-beam is in height, and honeycomb beam can be combined to form various section forms→ I-beam can be processed into T-beam, which greatly meets the needs of engineering design and manufacturing.→ compared with the concrete structure, the I-steel structure can increase the service area by %, reduce the self weight of the structure by % - %,Borujerd12Cr1MoVG seamless pipe manufacturer,BorujerdHow much is 40x40 galvanized pipe per meter, and reduce the structural design internal force. Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason, the special rolling method can be used to make full use of the skills of uneven deformation and pass design. For example, when the billet section is narrow and wide I-beam is required to be rolled, when the billet is wide and small I-beam is required to be rolled, the negative rolling method can be used Spread rolling, etc.

I-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.Economic management,It can withstand continuous moderate impact and can provide composite plates of various thicknessesClassification by end shape Remove defective pipes within the allowable length.BorujerdAt present, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.Some applications of I-beam:
