2022-08-24 01:47:18Spraying (throwing) derusting spraying (throwing) derusting is that the high-power motor drives the spraying (throwing) blade to rotate at high speed so that the steel sand, steel shot, iron wire section, minerals and other abrasives can be sprayed (thrown) on the surface of the square tube under the action of centrifugal force, which can not only completely remove rust, oxides and dirt, but also the square tube under the violent impact and force of abrasives, It can also achieve the required uniform roughness.The new improvement ensures that square tubes can be used for a long time. With the development of the times, square tubes are used in more and more fields. So how can we correctly choose square tubes? Next, I'll introduce the process of lower tubes.Square pipe is the name of square pipe, that is,There are sets of MPM and sets of MRK pipe mills in the world. Strength refers to the function of qb square tube data being destroyed under static load (appropriate plastic deformation or fracture). Because the action forms of load include tension, contraction, meandering, shear and so on, because the strength is also divided into tensile strength, compressive strength, flexural strength,Guaimaro42 galvanized square pipe, shear strength and so on. There is often a definite connection between various strengths. Long term square tube, square rectangular tube, seamless square tube, galvanized square tube and galvanized tube have no turnover to avoid price difference, and the price is % higher than the market price! The price of more than one ton is higher! In normal use,GuaimaroGalvanized square pipe equipment manufacturer, tensile strength is often taken as the fundamental strength gauge needle.Brinell hardness (HB), Rockwell hardness (HRC) and Vickers hardness (HV) are commonly used.. fake and inferior square tubes are easy to fold. Folding is a variety of broken lines formed on the surface of square tubes, and this defect often runs through the longitudinal direction of the whole product. The reason for the folding is that the fake and shoddy manufacturers pursue the rate, the reduction is too large, resulting in ears folding occurs during the next rolling, the folded products will crack after bending, and the strength of the square tube will be greatly reduced.
According to smelting classification and furnace type, A. open hearth steel: (a) acid open hearth steel; (b) Alkaline open hearth steel.The cheapest,Square pipe welding is suitable for surface treatment of materials. Square pipe welding can be used for ceramic ceramic, metal ceramic and metal metal welding.For the level of resistance welding cold formed square pipe, the size of R angle is generally between - times of the wall thickness. It can also produce R angle square pipe of the size required by customers according to customers' needs; Square pipe is a kind of long steel with hollow section and no joints around. It is a square pipe formed by four sides of seamless pipe mold. Square pipe has hollow section, professional square pipe, square rectangular pipe, seamless square pipe, galvanized square pipe, galvanized square pipe, strict inspection and quality assurance. The preferential activity is in progress. Welcome to consult. A large number of pipes are used for conveying fluid. They are mainly used in conveying, hydraulic support and mechanical structure, Medium and low pressure, high pressure boiler tubes, heat exchange tubes, gas, oil and other industries. It is stronger than welded and will not crack.Mechanical engineering, power plants, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, boiler construction, highway railings, housing construction, pressure vessels, oil storage tanks, bridges, power station equipment, heavy transportation machinery and other welded structural parts with high load, etc. Process classification: according to the production process, square tubes are divided into hot-rolled seamless square tubes, seamless square tubes and qb square tubes.Guaimaro, 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.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.Brinell hardness (HB), Rockwell hardness (HRC) and Vickers hardness (HV) are commonly used.
