When we carry out different projects, which can ensure the quality of the project. In many kinds of data, alloy pipe is widely used. In many projects, we will apply it, so it is very popular in the field. When people carry out the construction of alloy pipe project, there are many things that must be paid special attention to. Let&#;s take you to know: Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason, the special rolling method can be used to make full use of the skills of uneven deformation and pass design. For example, when the billet section is narrow and wide I-beam is required to be rolled, the wave rolling method can be used; for example, when the billet is wide and small I-beam is required to be rolled, the negative rolling method can be used Spread rolling, etc.Pozarevaz, In order to ensure the welding quality of pipes, welders shall be trained, the welder should consider the operation skills. The pipe welding process may include several postures of overhead welding vertical welding and overhead welding (when the pipe cannot rotate). The size of current should be selected to take into account the formation of vertical welding and overhead welding (some pipes are not very large, and the current cannot be adjusted in the middle of one formation). In the process, the stability and formation of arc should be controlled, It can swing properly,Pozarevaz2205 duplex steel welded pipe, and the forming shall be well combined with the necessary swing.What are the uses of I-beam?Morel gungi,The pickling agent in the pickling process contains many acidic substances, including hydrochloric acid, sodium cyanide, etc., which has strong corrosion and reduction, the corrosion resistance of alloy pipes is specified higher.The sodium cyanide passivation treatment of alloy pipe can be divided into four categories. Before passivation treatment, the surface of alloy pipe shall be clear of oil stains, pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned, and the workpiece of alloy pipe products can be infiltrated into aqueous solution. The passivation treatment of the alloy tube in sodium cyanide transforms the surface layer into a very thin passivation treatment film, which determines that the color of the surface layer has no change before and after passivation treatment, and the reproducibility of the solution is good.Due to the unique performance of I-beam, I-beam has successfully solved the problem of serious equipment wear in many industries.

Generally, there are many passivation methods for alloy tubes, especially in terms of construction or equipment manufacturing technology, the position of galvanized pipe is still relatively large. It is precisely because of this strong position that we can see this kind of building material in all walks of life, even in a field that seems to have little contact. It will be applied in many construction projects. At the same time, even in the depressed environment of the steel industry, the application situation and utilization rate of this kind of pipe are very high.Main uses: as a finished material, flat steel can be used to make hoop iron, tools and mechanical parts, and used as building frame structural parts and escalators in buildings. Flat steel is divided into two types according to its shape: plane spring flat steel and single-sided double groove spring flat steel. Hot rolled spring flat steel is mainly used to manufacture leaf springs for automobiles, tractors, railway transportation and other machinery.Latest consultation,The pickling agent in the pickling process contains many acidic substances, including hydrochloric acid, sodium cyanide, etc., which has strong corrosion and reduction, and the temperature of etching substances is relatively high. Therefore, the corrosion resistance of alloy pipes is specified higher.It is often asked that the shape of I-beam is similar to that of H-beam. What is the difference between them? Many people can&#;t explain it in detail. Here is a detailed answer for you: many people think that I-beam is a domestic name and H-beam is a foreign name. In fact, this cognition is wrong. H-beam and I-beam are different in shape!Last week the billet in North China market showed a slight rebound trend. The billet quotation in Tangshan, the leading city rose first and then stabilized in four trading days, with a strong wait-and-see atmosphere in the market. Affected by the almost stagnation of festival procurement, Tangshan billet fell by yuan during the Dragon Boat Festival holiday. On the first day after the festival, although the phase snail is still running at a low level, due to the small billet resources in the market, the steel mills unexpectedly rose, and the billet market rebounded. However, due to the continuous increase of capital pressure and the downturn in the transaction of downstream finished materials, the steel plant has always maintained a cautious wait-and-see attitude to maintain stability.

Plan scheme : high carbon steel with carbon content exceeding .% and alloy pipe with chromium content not less than %Convenient and efficient,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.Welded steel pipe also known as welded pipe, is a seamless steel pipe made of thick steel plate or hot-rolled strip by electric welding after coiling and forming, generally with a fixed length of m. Welded steel pipe has the advantages of simple production and processing process, high production efficiency, many types, specifications and models, and less investment in machinery and equipment projects, but the general compressive strength is less than that of seamless pipe.The shape of I-beam is similar to that of H-beam. What is the difference between them?Pozarevaz,When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size.Alloy steel pipe is a new type of seamless steel pipe connection pipeline. The selection of pipeline connection pipeline, whether it is fire water system software,PozarevazHow much is the I-beam of 18, water supply equipment, or pipeline, heat and national defense industrial pipeline system software of petrochemical pipeline system, so it can only bear the force in one direction.
