Defects of alloy pipe and solutions:Nitriding: also known as nitriding, it is the process of penetrating nitrogen atoms into the surface layer of steel. At present, gas nitriding is widely used in the production of alloy steel pipe.Iraclion,The storage of galvanized pipes should pay attention to several points. The first is the storage location. It cannot be placed in the open air, because in the open air, not only the safety of various products such as theft, but also corrosion problems will occur. Open air sites are vulnerable to various extreme weather conditions. Large amounts of rain or snow will erode the zinc coating on the surface to the greatest extent, which may lead to rust of the product. The second is the details of storage. It is not directly exposed to the sun. It shall be cooled and dried and shall not be stored with corrosive articles.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,IraclionPrecision cold drawn seamless pipe manufacturer, 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, If the current flows from the positive stage to the negative stage,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, 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.H-section steel is an economic section high-efficiency profile with more optimized section area distribution and more reasonable strength weight ratio. It is named because its section is the same as the English letter 'H'. There is no slope on the inner side of the two outer edges of H-section steel, which is straight. This makes the welding and splicing of H-section steel simpler than I-section steel, better mechanical properties per unit weight, and can save a lot of materials and construction time.Stages needing attention in the production and manufacture of alloy tubes

The section of I-beam has good straight pressure and tensile resistance, but the section size cannot resist torsion because the wing plate is too narrow. On the contrary, H steel has its own advantages and disadvantages.Metric welded pipe: it is used as seamless pipe in standard. The welded steel pipe expressed by outer diameter * wall thickness mm is welded by hot and cold strip welding of general carbon steel, high-quality carbon steel or Puneng low alloy steel, or it is made by cold drawing after hot strip welding. Metric welded pipe is generally used as structural parts, such as transmission shaft, or to transport fluid. The thin wall is used to produce furniture and lamps. It is necessary to ensure the strength and zigzag test of steel pipe.Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.discount,However, what we need to do now is to improve the production technology level of China&#;s production process of C-section steel, and step up the formulation of relevant industry standards and inspection standards. C-section steel manufacturers should keep close contact with truck manufacturers and communicate more. In this way, it is more conducive for C-section steel manufacturers to produce C-section steel products suitable for truck industry.→ I-beam can be processed into T-beam, and honeycomb beam can be combined to form various section forms, which greatly meets the needs of engineering design and manufacturing.When we carry out different projects, we must use different raw materials, which can ensure the quality of the project. In many kinds of data alloy pipe is widely used. In many projects,Iraclion12CR2MOG alloy pipe, 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:

The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.Inspection requirementsC-section steel has uniform zinc layer, smooth surface, strong adhesion, no zinc leakage and high dimensional accuracy. All surfaces are wrapped by zinc layer, and the zinc content on the surface is usually -g /? It has long service life, corrosion resistance and durability. It is a kind of stronger protection.What are the quality protection measures for galvanized pipe during weldingThe section of I-beam has good straight pressure and tensile resistance, but the section size cannot resist torsion because the wing plate is too narrow. On the contrary, H steel has its own advantages and disadvantages.Iraclion,IraclionHow much is the alloy tube,I-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows:Aiming at the connective tissue and texture produced in stainless steel plate Position and other crystal defects are generally removed by heat treatment processes such as quenching or quenching. The effect of quenching is to optimize the crystal, eliminate structural defects, reduce strength, improve plastic deformation, and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe, quenching machinery and equipment cannot be lacked. Therefore, the formulation of appropriate annealing process is a necessary condition to ensure that the alloy pipe mechanism meets the standard and the commodity does not crack. If the manufacturer in order to better one sidedness, reduce the product cost and reduce the quenching process
