2023-11-18 09:43:26Forging square tube: a kind of pressure processing in which the reciprocating impact force of the forging hammer or the pressure of the press changes the blank into the shape and size we need. It is generally divided into forging and die forging. It is often used to produce large-scale materials and materials with large square tube size.Functional index analysis of qb square tube - the load on the machine parts due to the great progress of strength is called the frontal collapse load. The power of destruction of qb square tube under the frontal collapse load is called the frontal collapse toughness.Mayagus,Send to metal flaw detector (or hydrostatic test) for internal flaw detection. If there are cracks, bubbles and other problems inside the steel pipe they will be detected. Steel pipes should be strictly selected manually after quality inspection. After the steel pipe is inspected, the number, specification,Hardness QB square hardness is a pointer to measure the hardness and softness of metal materials. At present, the hardness method is commonly used to measure the hardness in production. It uses the indenter with fixed geometry to measure the hardness value of the metal material surface tested under fixed load according to the degree of hardness.The pressurization size and time are the key to the success or failure of welding. If the square tube synthetic material is not pressurized, a large number of pores will be caused due to the pores of the material itself and the gas generated in the reaction. It is not allowed to leave the reactants in the weld, so it must be densified, usually pressurized during the reaction.The advantage of empty bending is that it can bend the side length when the real bending cannot be carried out, such as synchronous bending and finishing of the upper side and side of qb square tube. Empty bending can also bend the inner corner of r.t without breaking the tube wall.
Cleaning solvent and emulsion can clean the surface of square tube to remove oil, dust, agent and similar organic matter, but it can not remove rust, welding etc. on the surface of square tube, so it is only used as an auxiliary means in production.Square tube is a kind of square tube, which is rolled by strip steel after process treatment. Many kinds of materials can form a square tube body. It is used for what purpose and where. Most square tubes are steel tubes, mostly structural square tubes, decorative square tubes and building square tubes. Generally, the strip steel is unpacked,MayagusWhat kind of galvanized pipe is 32, leveled, crimped and welded to form a circular tube, which is rolled into a square tube and then cut to the required length. Usually pieces per bag.If there is only a single plane weld, the step-by-step back welding shall be adopted from the middle, that is the arc of the section weld shall be terminated at the section arc.Click to view,Tool derusting mainly uses tools such as steel wire brush to polish the surface of square pipe,MayagusSpecification of galvanized round pipe, which can remove loose or oxidized scale, rust, welding slag,MayagusGalvanized seamless pipe, etc. The derusting of manual tools can reach grade SA and that of power tools can reach grade SA. If the square pipe surface is firmly attached with iron oxide scale, the derusting effect of tools is not ideal and can not reach the anchor depth required by construction.The pressurization size and time are the key to the success or failure of welding. If the square tube synthetic material is not pressurized, a large number of pores will be caused due to the pores of the material itself and the gas generated in the reaction. It is not allowed to leave the reactants in the weld, so it must be densified, usually pressurized during the reaction.The second is the pickling of the square pipe. Both chemical and electrolytic methods are used when pickling the square pipe. These two methods can remove the oxide skin of the square pipe.
When the vehicle is replaced with seamless square tube blank, the material is too soft to affect the requirements, so as to ensure the quality of parts and avoid wrinkles.Fair price,The surface of galvanized square pipe treated by sand blasting, shot blasting or pickling process is relatively clean, and the oxide scale and rust are removed, which improves the adhesion of the coating. When the installation site unconditionally adopts sand blasting and shot blasting, manual and mechanical derusting can be adopted, but the derusting quality level must be reached.The common surface treatment of square pipe includes surface treatment, chemical treatment, shot blasting treatment, manual mechanical treatment and flame treatment. The treated will be separated. ~ Mpa compressed air entrains abrasives, and the nozzle sprays to the steel surface at high speed. The impact and friction of abrasives remove the oxide scale, rust and dirt on the steel surface, and make the steel surface reach a certain roughness.The surface of fake and inferior square tubes is easy to produce scabs. There are two reasons: the material of fake and inferior square tubes is uneven and there are many impurities. The guide equipment of fake and shoddy material manufacturers is simple and easy to stick to steel. These impurities are easy to scar after biting the roll.Mayagus,Fake and shoddy square tubes are easy to scratch, because the equipment of fake and shoddy material manufacturers is simple and easy to produce burrs and scratch the surface of square tubes. Deep scratches reduce the strength of square tubes.With the progress of the times and the development of science and technology, the application fields of square tubes are widely divided. The main fields are the construction industry. Affected by the environment and weather, square tubes will also rust for a long time. How to improve the rust resistance of square tubes and what are its rust resistance? Let me give you a detailed introduction below.With the progress of the times and the development of science and technology, the application fields of square tubes are widely divided.
