b. The professional two-sided arc welding processing technology can complete the electric welding at a good position, which is not easy to have the disadvantages of staggered joint, welding deviation and incomplete penetration, and it is very easy to manipulate the welding quality.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, 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:Chimaltnango,In order to ensure the welding quality of welded pipe,ChimaltnangoGH2132 superalloy tube, the forming roll, guide roll, extrusion forming roll and sizing roll must be adjusted once, and then the most important thing is to adjust the closing plate hole, guide roll and extrusion forming roll of the forming roll. Among them, the guide roller has the s of controlling the weld direction of the welded pipe and the height width ratio of the finished rolled pipe, reducing the edge widening, controlling the edge springback of the finished rolled pipe, and ensuring that the weld is vertical without screwing into the extrusion roll.Difference and application description between H-beam and I-beamBaritone,→ compared with general section steel, it has the advantages of low cost, high precision and small residual stress. It does not need expensive welding materials and weld detection, and saves about % of the manufacturing cost of steel structure.So why is the alloy pipe easy to rust after being pickled and passivated by the software?Alloy tube is widely used in our daily life, which provides us with great assistance.
The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.The smooth of steel pipe is mainly through tension reducing, which is a continuous rolling process of hollow base metal without center and tip. Under the condition of ensuring the capillary welding quality, the whole welded pipe is heated to more than ℃ by the welded pipe tension reduction process, and then rolled to finished pipes with various outer diameters and wall thicknesses by the tension reduction machine ( times in total). The fluid pipes produced by developed countries in the world have adopted the welded pipe smooth process in a large number of boiler pipes. With the development of society, Domestic hot welded pipe has gradually formed a situation to replace smooth pipe.I-beam is widely used in buildings or other metal structures.Manufacturing cost,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, and the reproducibility of the solution is good. Hot push hole diameter. More sensitive applications and facilities of such methods require simplicity, low cost, easy maintenance, durable economic development and convenient product specification transformation. For example, the production of large diameter must be grooved pipe, elbow and similar products. You only need to add some spare parts. The expansion method of hot push can be used to process and manufacture large-diameter, thick wall and thin alloy steel pipes, and can not exceed the working capacity of thick wall pipes of machinery and equipment.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,ChimaltnangoASTM A106B seamless pipe,ChimaltnangoHow much is an I-beam meal, also known as H-beam, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.
Cold extrusion. This kind of processing method is more purposeful. Before the preparation of steel processing and extrusion molding, when the extrusion molding is used for mm diameter pipe fittings, the investment of machinery and equipment is less, so the raw material consumption is also very small, and the technology is relatively perfect. Once the tube size is increased, the cold extrusion method must have large cargo capacity and high-power machinery and equipment. Therefore, because the section size is relatively high and narrowWhether I-section steel is ordinary or light, so it can only be directly used for members bent in the plane of their web or form lattice stressed members.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.I-beam is divided into ordinary I-beam and light I-beam. The specification of hot rolled ordinary I-beam is -#. The specification of hot-rolled flexible I-beam supplied through agreement between the supplier and the buyer is -#. I-beam is mainly used in building structure, vehicle manufacturing, other industrial structures and fixed panels and cabinets. I-beam is often used together with I-beam.ChimaltnangoHeating surface tubes for low and medium pressure boilers (working pressure is generally not greater than MPA and working temperature is below ℃);I-beam is widely used in buildings or other metal structures.The delivery length of I-beam is divided into fixed length and double length, and the allowable difference is specified in the corresponding standards. The length selection range of domestic I-beam is divided into -, - and - according to different specification numbers. The length selection range of imported I-beam is generally -.
