After determining the reasonable pickling agent and polishing solution, it is very easy to carry out hot galvanizing for relevant alloy pipes. Use 'phosphating treatment' to degrease the pipes of electrolytic machine equipment, put them into the aqueous solution with zinc salt after pickling and passivation, connect the negative level of electrolytic machine equipment, put them into the cold-rolled steel plate in the direction corresponding to the pipes, and connect the switching power supply,Prime Minister ineroHow much is 80 welded pipe per meter, If the current flows from the positive stage to the negative stage, a layer of zinc is deposited in the pipe.a. In the forming process the thick steel plate has uniform deformation, small internal stress and no scratch on the surface. The alloy pipe produced and processed has higher coordination ability in the scope of size, specification and model of diameter and wall thickness, especially in the production and manufacturing of steel structure design grade thick wall pipe, especially medium diameter small thick wall pipe, which has incomparable advantages of other processing technologies, and can meet a large number of customer regulations on the specification and model of alloy pipe.Prime Minister inero,What are the quality protection measures for galvanized pipe during weldingIts heat sealing effect is remarkable. It can be directly buried immediately, which can not only save resources, but also reduce consumption, not occupy the natural environment but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment, unique and convenient installation, and reduce the construction cycle time of the project. On the whole,Key technical characteristics of alloy pipe:The system is mainly composed of control box, finishing roller, pre leveling unit, finishing unit and straightening unit.Defects of alloy pipe and solutions:

→ under the same section load, its application life is longer. Secondly, this kind of pipe has strong resistance to baking. In case of critical situation, it will not lead to the collapse of building structure in a short time. In addition,Prime Minister ineroQ345 thick wall seamless pipe, this kind of pipe also has a practical advantage, that is, it is more convenient and lighter when carrying out the construction and installation. The operators save time and labor when carrying out the construction, and the operation efficiency has been greatly strengthened. In this regard,I-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows: The defects can be removed by grinding with sand wheel, but the remaining wall thickness must be within the allowable standard.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. The specifications of the first two are -, that is, the corresponding height is -. At the same height, the light I-beam has narrow flange, thin web and light weight. Wide flange I-beam, also known as H-beam, 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.

Hot stamping. Fix the plan product workpiece or preformed vacancy on the rotating journal, with the wheel working pressure vacancy, radial wheel. After one or several solutions, there can also be a variety of methods for the whole process of hollow thick wall rotating body products. Products manufactured by high-precision processing method have excellent physical properties, specification scope, mold shell and software requirements, which are very simple, very easy to be replaced, and relatively low product cost. The processing time is not long enough, the processing capacity is not high the total length of processing pipeline is limited, and the size of machinery and equipment is generally short.Meticulous workmanshipAlloy pipe is a kind of seamless steel pipe. Alloy pipe is divided into structural seamless pipe and high-pressure heat-resistant alloy pipe. It is mainly different from the production standard and industry of alloy pipe. Annealing and tempering of alloy pipe changes its mechanical properties. Meet the required processing conditions. Its performance is higher than that of ordinary seamless steel pipe, its utilization value is higher, the chemical composition of alloy pipe contains more Cr, and its performance of high temperature resistance, low temperature resistance and corrosion resistance. Ordinary carbon seamless tubes do not contain alloy components or have few alloy components. Alloy tubes are widely used in petroleum, aerospace, chemical industry, electric power, boiler and other industries because the mechanical properties of alloy tubes change and are easy to adjust.The whole structure is composed of zinc and quaternary crystals, forming dense crystals and barrier layer on the plate, which effectively prevents the penetration of corrosion factors. From the point of view of the strong zinc corrosion resistance of the barrier layer,Prime Minister ineroHow much is 18 I-beam, when the zinc sacrificial anode is at the forefront of protection the scratches and scratches of some coatings and the insolubility of zinc oxide layer play a protective and blocking role.All the cracks occur at -mm away from the edge below the alloy pipe, and the macroeconomic orientation is vertical to the cold rolling orientation, showing a 'high mountain' shape.Prime Minister inero,With the development of steel structure buildings, only I-beam is not enough, that is, thickened I-beam, and the macroeconomic orientation is vertical to the cold rolling orientation, economizers, superheaters, reheaters, pipes for petrochemical industry, etc. for high-pressure boilers (working pressure is generally above MPa and working temperature is between ℃ ~ ℃)
