Alloy pipe is a spiral seam seamless steel pipe, which is made of hot-rolled strip steel coil, often processed by warm extrusion and welded by automatic double wire double side arc welding process. The alloy pipe sends the hot-rolled strip steel to the welded pipe unit, and the hot-rolled strip steel is extruded through multiple passes. The hot-rolled strip steel is rolled slowly to produce annular pipe material with open mouth gap. Adjust the reduction amount of the extrusion roll to control the welding gap at ~ mm and make both sides of the weld flush.In order to make the steel pipe workpiece have the required mechanical, physical and chemical properties, in addition to the reasonable selection of materials and forming processes, heat treatment process is often essential. Steel is the most widely used material in the mechanical industry. The microstructure of steel is complex and can be controlled by heat treatment. Therefore, the heat treatment of steel is the main content of metal heat treatment. In addition aluminum, copper magnesium, titanium and their alloys can also change their mechanical, physical and chemical properties through heat treatment to obtain different service properties.Kotui,Galvanized pipe cleaning, east-west derusting, pickling and shot blastingAiming 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,KotuiQ345B welded pipe manufacturer, reduce strength,KotuiHow much is 25 galvanized pipe per meter, 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, it will eventually lead to bad harm to the product quality.turkey,→ compared with the concrete structure, the I-steel structure can increase the service area by %, reduce the self weight of the structure by % - %, and reduce the structural design internal force.Alloy tube is widely used in our daily life, which provides us with great assistance. So what industries are alloy tubes applied to? Let&#;s follow the steps of all manufacturers and have a look together:

I-beam can be divided into four types according to shape: cold-formed equal edge I-beam, cold-formed unequal edge I-beam, cold-formed inner crimping I-beam and cold-formed outer crimping I-beam.Oxygen blowing welded pipe: it is used as steel blowing pipe. Generally, small-diameter welded steel pipe is used. There are eight standards from / inch to inch. Made of , , , or q-q steel strip. In order to prevent corrosion, some are aluminized.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.Finance Department,Heating surface tubes for low and medium pressure boilers (working pressure is generally not greater than MPA and working temperature is below ℃);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:Stages needing attention in the production and manufacture of alloy tubes

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 -.Discount,Alloy pipes can be used for heating (cooling) projects.Seamless pipeHeating surface tubes for low and medium pressure boilers (working pressure is generally not greater than MPA and working temperature is below ℃);Kotui,H-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange, and the second is that the inner surface of the flange has no inclination, and the upper and lower surfaces are parallel. The section characteristics of H-beam are obviously better than those of traditional I-beam,Kotui50 welded pipe more than one meter, channel steel and angle steel.Function of I-beam: where is I-beam mainly used?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.
