I-beam is mainly divided into ordinary I-beam, it is divided into wide, medium and narrow flange I-beams. The specifications of the first two are -, that is, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam,Metapan 12Cr1MoVG high pressure alloy pipe, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards. Judged as failing.Metapan , Spiral seam submerged arc welded steel pipe for general low-pressure fluid transportation (SY / t- is a submerged arc welded steel pipe for general low-pressure fluid transportation such as water, gas, air and steam, often warm spiral forming and double-sided active submerged arc welding or single-sided welding.The system is mainly composed of control box, finishing roller, pre leveling unit, finishing unit and straightening unit.Aliwal North, Remove defective pipes within the allowable length.→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.At present, there is still a big gap in the production technology of C-section steel between China and foreign countries.

H-shaped steel groove is deep and thick, and can withstand forces in two directions.Straight seam welding is adopted for larger diameter welded pipe, and spiral welding is mostly adopted for large diameter welded pipe; According to the top appearance of seamless steel pipe, it is divided into annular welded pipe and special-shaped (square, pitch, etc.); according to different materials and main purposes it is divided into mining anti liquid transportation welded steel pipe, hot-dip galvanized welded steel pipe for bottom pressure liquid transportation, continuous conveyor idler electric welded steel pipe, etc. it is arranged from small to large according to diameter * wall thickness according to the specification, model and dimension table in the current standard.H-shaped steel groove is deep and thick, and can withstand forces in two directions.Quality inspection report,→ compared with the concrete structure, the I-steel structure can increase the service area by %, reduce the self weight of the structure by % - %, and reduce the structural design internal force.I-beam is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.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.

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.High value,Metapan 16Mn large diameter longitudinal welded pipe,The side length of I-beam is small and the height is large, so it can only bear the force in one direction.Reinforcement mesh is manufactured by automatic and intelligent production line under the strict quality control of the factory. Grid size, reinforcement specification and quality are strictly controlled. The longitudinal and transverse bars of the reinforcement mesh form a network structure, so it has good bonding and anchorage with the concrete, and the load is evenly distributed,Metapan How much is 165 galvanized pipe per meter, which obviously shows the seismic crack resistance of the reinforced concrete structure.What is nitriding of alloy pipeMetapan ,I-beam can only be used for beam, while H-beam can be used for load-bearing column of structure. Miscellaneous scabThe 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.
