What should we pay attention to in the production of alloy pipeI-beam, whether ordinary or light, can only be directly used for bending members or lattice members on its Web because of its large and narrow section size and large moment of inertia difference between the two main axes on the section. It is not suitable for axial compression members and flexural members perpendicular to the web plane, so its application range is very limited. I-beams are widely used in buildings and other metal structures.Giza,Galvanized pipe cleaning,GizaGb9948 price of seamless pipe, east-west derusting pickling and shot blastingThe finished product has smooth surface, low friction coefficient, flatness error + / - mm / m length, wear resistance and maximum temperature of ℃Dolisie, Peak crackClassification introductionRequirements of alloy tubes for low and medium pressure boilers

After isothermal quenching treatment, the modified LNs steel of case hardening steel also has the surface compressive stress characteristics obtained by heat treatment.How are seamless tubes made?→ compared with the concrete structure, the I-steel structure can increase the service area by %, reduce the self weight of the structure by % - %,GizaHow much is the labor of galvanized pipe per meter, and reduce the structural design internal force.production costsPlan option : Martensitic chromium alloy pipe, not very little aluminum alloy, and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace. Because the physical properties of alloy tubes are easy to change and adjust. Frame line crack

Small longitudinal cracksupply,Alloy pipe is a spiral seam seamless steel pipe, which is made of hot-rolled strip steel coil, often processed by warm extrusion and welded by automatic double wire double side arc welding process. The alloy pipe sends the hot-rolled strip steel to the welded pipe unit, and the hot-rolled strip steel is extruded through multiple passes. The hot-rolled strip steel is rolled slowly to produce annular pipe material with open mouth gap. Adjust the reduction amount of the extrusion roll to control the welding gap at ~ mm and make both sides of the weld flush.Thin wall steel pipe,Giza09CrCuSb alloy pipe, thick wall steel pipe.It is widely used in various fields of national economic construction, such as buildings, bridges, oil drilling platforms, vehicles, highways, subways, steel structure plants and large warehousesGiza,Due to the relatively high and narrow section size of ordinary I-beam and light I-beam, the moment of inertia of the two main axes of the section is quite different, which makes it very limited in the scope of application. The use of I-beam shall be selected according to the requirements of design drawings. The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.Determined by the shape, the section modulus, moment of inertia and corresponding strength of I-beam are obviously better than those of ordinary I-beam with the same single weight. When used in metal structures with different requirements, it shows its superior performance in bearing bending moment, pressure load and eccentric load. Compared with ordinary I-beam, it can greatly improve the bearing capacity and save metal by % ~ %.
