Reasons for the magnetic field of spiral steel pipe ​ In the welding process, welding by DC welding, in welding line, and the position of the welding head due to the high current, resulting in a strong magnetic field, pipe body under the action of magnetic field, magnetic moment or tend to obtain and external magnetic field in the same direction are arranged. When the welding end, magnetic field gradually decreased till disappeared, due to the hysteresis phenomenon, in the tube body and residual magnetic flux density, this is what we say normally remanence. The harm of spiral steel tube magnetic field Existent remanent magnetization, the image intensifier and the electron beam deflection and X-ray industrial TV image system produced the “s” type distortion, influence porosity, slag and other natural defects, especially the detection rate of incomplete penetration, cracks and other linear natural defects. With the change and improve X ray image intensifier TV system pipeline steel grade, the remanence was particularly prominent. Remanence existence, ring butt in the pipeline, will produce the phenomenon of partial arc, welding quality. Remanence have seriously affected the quality of construction The AC degaussing method of spiral pipe is the most common method: 1, with the coil around the outside of the steel tube, to the coil through the alternating current, slowly reduce the current of alternating current, until reduced to zero. Degaussing results: don’t change the physical properties of spiral steel pipe, however, once again encountered the external magnetic field, spiral steel tube also is magnetized. 2, through the heat treatment process, can be more thoroughly the degaussing, however, after degaussing, hardness and rigidity of the spiral pipe will change, encountered again in the future the external magnetic field, plus the magnetic field is removed, the steel pipe can basically there is no residual magnetism. 3, heat treatment process, is probably: oxygen free heating to a certain temperature, and then, with 72 hours slowly cooling to room temperature.

It is generally believed that the non metallic inclusions in the steel pipe can destroy the continuity and compactness of the steel pipe, and the serious inclusions will lead to the emergence of the phenomenon of steel tube delamination. Another idea is hydrogen induced cracking, which is due to the formation of white spots in the circular tube, the formation of white spots in the circular tube, the formation of layer defects in the rolling process. In addition, the stress exceeds the plastic rotation of the two roller is not uniform deformation, can also lead to the strength of the layered. Control measures of internal layer of steel pipe: 1, improve the plastic toughness of steel tube Improving the cleanliness of molten steel, reduce harmful impurities; increase the proportion of the axis of the floor, reduce the central segregation and central porosity; the reasonable cooling system, avoid cracks in plate; billet rolling plate or offline slow cooling process, reduce internal stress, so as to ensure the organization performance and billet and finished products meet the technical standards. 2, reasonable control of heating temperature The best heating temperature is selected by measuring the thermo plastic curve. Also note that there is enough time to heat the heating pipe to reduce the plastic deformation resistance, improve the toughness. 3, reduce the roll speed Speed is a key parameter for the roll piercing process, in which the rolling speed changes from low to high, and there is a critical delamination starting to roll speed. At lower roll speeds, it is easy to form the lumen; the higher the roller speed, and the delamination defects of the capillary formation are easy to form. In order to eliminate the delamination defects and the capillary, the roll speed should be reduced to the critical delamination starting at the roll speed.

Steel pipe concrete structure is a novel composite structure made of concrete filled steel tube formed. Because steel concrete structure to more effectively play two materials steel and concrete respective advantages, while overcoming the disadvantages of steel structures is prone to local buckling. Steel concrete structure in accordance with the section of the form can be pided into rectangular steel concrete structures, concrete structures and polygonal circular steel pipe and other concrete structures, including rectangular and circular steel pipe concrete structure concrete structure wider application.  As we all know, the concret has high compressive strength. But flexural capacity is weak, and steel, in particular, strong steel bending ability, with good plasticity, but when pressure is easy to lose axial compressive buckling capacity. The steel concrete in the structure can be combined with the advantages of both, can make concrete lateral pressure in the state, the compressive strength can be doubled. While the presence of the concrete to improve the rigidity of the pipe, the two function together, thus greatly improving the carrying capacity. As a new steel concrete composite structures, mainly in axial compression and a smaller force eccentric compression member-based, is widely used in the framework of the structure (such as factories and high-rise). The rapid development of steel concrete structure is due to its good mechanical performance and construction performance, manifested in the following aspects: 1. high capacity, good ductility, excellent seismic performance Concrete filled steel columns, steel restraints on its internal concrete in the concrete three-state pressure to improve the compressive strength of concrete; steel inside the concrete and steel can effectively prevent the occurrence of local buckling. Research shows that the bearing capacity of concrete filled steel tube column is higher than the corresponding steel and concrete Columns Columns sum. Interaction between steel and concrete steel inside the concrete so damaged by brittle failure into a plastic failure, significantly improved ductility components, energy dissipation capacity is greatly improved, with excellent seismic performance. 2. construction convenient, greatly shorten the construction period When the steel construction of concrete structures, steel skeleton can be used as fresh bear the weight of construction loads and structural construction phase, the construction is not affected by concrete curing time; due to the steel reinforcement inside the concrete is no easy pouring concrete and tamping; steel concrete structure construction, no template, saving formwork, form removal of material and labor costs, but also saves time. 3. in favor of fire-resistant steel and fire Because the pipe is filled with concrete, can absorb a lot of heat, so when subjected to fire string section of the temperature field distribution is very uneven, increasing the pillar of fire resistance time, heating rate slows steel columns, steel columns and once yielded concrete Most can withstand axial load, to prevent structural collapse. The fire resistance of composite beam will increase, because the temperature of the steel beam from the top flange of the heat will be transmitted to the concrete increases. 4. corrosion resistance than steel Pouring concrete steel pipe exposed area decreased by much less than the area of ​​the external gas corrosion of steel, corrosion and corrosion than steel cost savings. Cross-section in the form of steel concrete structures affect the mechanical properties of steel concrete structure, the degree of difficulty of construction, construction period and project cost has greatly. Circular steel circular pipe by means of concrete compression members bound by its effective role inside the concrete, the steel pipe inside the concrete in three-pressed state has a higher compressive strength of the concrete.
