Alloy pipe is a very important way and type of seamless steel pipe. Its use is relatively common. It is widely used in various engineering projects, house construction and building decoration. Its fracture will always be found in the production, manufacturing and key marketing of alloy pipe, That is many stages of production and processing are not done well. Another is that the seasoning is not enough and the proportion of chemical molecules is wrong. There are all reasons.The finished product has smooth surface, low friction coefficient, wear resistance and maximum temperature of ℃San Cristo balvilapas,The first is people. Human factors are the control focus of welding. Therefore, before welding, welders with skilled technology and welder certificate shall be selected for necessary technical training and disclosure. It shall not be replaced at will to ensure the relative stability of the welders welding the pipeline.→ under the same section load, the weight of hot-rolled H steel structure is reduced by % - % compared with the traditional structure.Dessie, I-beam has no specific composition and performance series.I-beam has wide flange, thin web, many specifications and flexible use. It can save metal by % ~ % when used in various truss structures. Because the inner and outer sides of the flange are parallel and the edge end is at right angles, it is easy to assemble and combine into various components, which can save about % of the welding and riveting workload, greatly accelerate the construction speed of the project and shorten the construction period.When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size. I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, it is divided into wide, medium and narrow flange I-beams.
X-ray or ultrasonic testing shall be carried out for repair welding of alloy pipe dead end welding of strip steel and circumferential seam. For the spiral welding of steel for the transportation of flammable general liquids, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water, wastewater, heating steam and other general liquids,San Cristo balvilapasGh4037 alloy pipe, X-ray or ultrasonic testing sampling inspection (%) shall be carried out. Straight seam electric welding steel pipe (yb- is a steel pipe whose weld is longitudinally parallel to the steel pipe. It is usually divided into metric welded steel pipe, welded thin-walled pipe, transformer cooling oil pipe, etc.As shown in the name, I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination, generally :, which makes the outer flange thin and the inner flange thick. Therefore, the section characteristics of I-beam in the two main planes are very different, and it is difficult to give full play to the strength characteristics in application. Although the thickened I-beam has also appeared in the I-beam market, the structure of the I-beam has determined its torsional performance.details,Alloy pipe is a very important way and type of seamless steel pipe.

Its fracture will always be found in the production, That is, many stages of production and processing are not done well. Another is that the seasoning is not enough and the proportion of chemical molecules is wrong. There are all reasons. Miscellaneous scabWhat is the purpose of flat steel
I-beam is widely usedIndustry management,→ 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. When the end span plate is connected with the concrete beam for structural reinforcement, the length of the surface mesh reinforcement extending into the beam shall not be less than d. When the beam width is small, the extended reinforcement shall be bent . When the perimeter of the floor is poured integrally with the concrete beam or wall, the length of the surface mesh reinforcement extending into the beam shall not be less than the anchorage length of the small reinforcement required by the standard (without transverse reinforcement), when the beam width is small, the extended reinforcement shall be bent.Dehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlementSan Cristo balvilapas,The finished product has smooth surface, low friction coefficient, flatness error + / - mm / m length wear resistance and maximum temperature of ℃It is widely used in various fields of national economic construction, such as buildings, bridges,San Cristo balvilapasQuotation for spiral welded pipe, power stations, oil drilling platforms, vehicles, highways, subways, steel structure plants and large warehousesSome applications of I-beam:
