<p> The main functions and advantages of Jiangmen En flat welded pipe When the forging temperature is between 40 ° C and 40 ° C, Jiangmen En square tube rectangular tube precipitates band-shaped austenite from the austenite along the direction of metal flow. Undissolved austenite is cut into banded austenite. When cooled to A, the banded austenite transforms into banded pearlite. This can be improved or eliminated by increasing the finishing rolling temperature, forging ratio, diffusion annealing or normalizing. Founding glory Jiangmen Enping factor chloride ion corrosion Chloride ion is an example that exists in nature in many places, such as salt, sweat, sea water, soil, and so on. Although the rectangular tube has good corrosion resistance, in an environment where a large amount of chloride ions are present, the corrosion performance is relatively weakened, resulting in rust. Therefore, the use of rectangular tubes has environmental requirements and cannot be used in environments containing a large amount of chloride ions. Functional index analysis of variable-cost thick-walled square tube-mechanical function of plastic square tube. Market Wuhu: It is a square tube that puts metal in a closed container and applies pressure at the end to make the metal extrude from a prescribed die hole to obtain a finished product of the same shape and size. It is mostly used for nonferrous metal square tubes. Before introducing the classification of steel, the basic concepts of ferrous metal, square tube steel and non-ferrous metal are briefly introduced. Customized thick-walled square tube solution saves raw materials: The material rate of cold parts can usually reach more than 80%. For example, the material rate of the cutting and machining of the automobile brand is 43%, and the material rate is 92% when it is cold. When the universal joint bearing sleeve is changed to cold, the material rate is increased from 28% to 28%. It can be seen that using good mechanical parts can save a lot of steel and non-ferrous materials. The main functions and advantages of Jiangmen En flat welded pipe are the same as for isothermal quenching of the surface hardening treatment of q345c seamless rectangular pipe, which is the heat treatment technology. After isothermal quenching, the Q345C seamless rectangular tube will obtain more and better performance, and make the Q345C seamless rectangular tube used in more fields. Inspection requires inspection of packaging and protective layer process of protective materials </ p> <p>

</ p> <p> The main functions and advantages of Jiangmen Enping welded pipe can not only enlarge the physical adsorption of the surface of the pipe, but also enhance the mechanical adhesion of the layer and the surface of the pipe. Therefore, spraying (polishing) rust removal is an ideal way to remove rust from pipes. Generally speaking, shot blasting (sand) rust removal is mainly used for pipe inner surface treatment, and shot blasting (sand) rust removal is mainly used for pipe outer surface treatment. Several problems should be noticed when using spray (polishing) to remove rust. Large-caliber thick-walled square tubes are good for purchasing Baosteel materials when doing cold drawing. Because Baosteel's materials have undergone level flaw detection treatment, the density of the steel is better. After cold drawing and heating, it is easy to make a trip. The bend of the rectangular tube is not greater than 2 mm per meter. , The total curvature is not greater than 0.2% of the total length. After calcium treatment, the inclusions in the thick-walled square tube can be well denatured, and the morphology of the sulfide in the rolled material is also good. Jiangmen Enping has many processing technologies for large-caliber thick-walled square pipes. I will not introduce the specific processing technology here. Everyone only knows the processing technology of large-caliber thick-walled square pipes. Maybe it ’s There is insufficient understanding of the heating process. I will introduce the heating process of the large-caliber thick-walled square tube in detail below. How much does it cost? The current large-caliber thick-walled square pipe also has very good performance, strong corrosion resistance and strong heat resistance, and has been widely used in many scientific and technological fields, so even so, the wise men still The research on the surface anti-adhesion of large-caliber thick-walled square pipes has not stopped. In the future, large-caliber thick-walled square pipes will get better performance and make more important contributions to development. For structural use: for piling pipe, bridge; pier, road, building structure pipe, marine piling pipe, etc. Technical innovation Alxa strength Q235B square strength refers to the performance of metal materials under static load (excessive plastic deformation or fracture). Because the load acts in the form of tensile, compression, bending, shearing, etc., the strength is also divided into tensile strength, compressive strength, flexural strength, shear strength and so on. Various strengths are often fixed. Tensile strength is used as the basic strength indicator. Precision tubes are seamless pipes for mechanical structures, hydraulic equipment with high dimensional accuracy and good surface finish. The selection of precision seamless manufacturing machinery structure or hydraulic equipment can greatly save machining man-hours, increase material rate, and help improve product quality. The seamless tube is rolled in a circular hole pattern consisting of a circular hole groove with a variable cross-section and a fixed cone head. Cold drawing is usually performed on a single-chain or double-chain cold-drawing machine. The perforated rods and rods are moved in a closed cylinder, so that the parts are extruded from the smaller die holes. Jiangmen Enping galvanized rectangular pipe, this method can be used for small diameter steel pipes. The main function and advantage of Jiangmen Enping welded pipe is that the band structure is caused by the segregation of alloying elements in the steel, especially the segregation of sulfur and phosphorus, Jiangmen Enping DN25 galvanized steel pipe, and various non-metallic inclusions that easily form a band structure. Materials, such as manganese, silicate, etc. Dendritic segregation during the solidification of steel cannot be eliminated during subsequent pressure processing, and it often remains band-shaped. In addition, improper thermal bonding and forging processes, especially in the absence of repeated forging and reverse forging in different directions, will also retain the band shape of the raw material. The system is a horizontal frame designed according to box-shaped holes. The frames are oval holes. The other frames are approximately rectangular holes. The cross-section of the hole is composed of arcs, and the radius of the arc increases from frame to frame. The fillet radius at the junction is equal to the fillet radius of the finished section. The large-elongation thick-walled square pipe has an overall elongation coefficient of about 05. It is mainly distributed on flat rolls. The vertical roll has a small amount of deformation. Its role is to press down the short sides of large-diameter thick-walled square pipes. With this design, the calculation is more complicated, and the calculated value is not accurate enough, and the perimeter of the hole pattern needs to be constantly modified. OK </ p> <p>

</ p> <p> The main functions and advantages of Jiangmen En flat welded pipe are galvanized welded square pipes for low-pressure fluid transportation. The standard number is GB / T3092-2008. The representative material is the same as above. It is mainly used to transport water, gas, air, oil and heating fluids with low pressure, such as hot water or steam. The surface of the square tube is hot-dip galvanized or cold-galvanized. The advantage of the quality inspection report for empty bending is that it can bend side lengths when real bending cannot be performed, such as simultaneous bending and finishing of the upper / side edges of a rectangular tube. The empty bend can also bend the inner angle of R <0.2t without breaking the pipe wall. Main applications for supplying large-caliber thick-walled square tubes: q345c seamless rectangular tube undergoes various lower bainite isothermal quenching process tests. After isothermal quenching, the surface compressive stress characteristics of q345c seamless rectangular tube will be obtained. Analytical technology for sizing rolling of thick-walled stainless steel square tube. Because the inside surface has no tools during sizing rolling, the shape of the inner surface of the rolled material is uneven when rolling thick-walled tube. When a roll mill is used, the shape of the inner surface of the rolled material is angular. The dimensional finite element method was used to analyze the mechanism and countermeasures of this inner angular phenomenon. Work instructions are at -10 ° C. Material of thick wall square tube: Q23 Q345 (16Mn), 20 #, alloy steel, stainless steel. </ p>
