Product description of square tube square tube is a light thin-walled steel tube with hollow square section, also known as steel cold-formed profile. It is a section steel with square section shape and size, which is made of Q hot-rolled or cold-rolled strip or coil as the base material, the corner size and edge flatness of hot-rolled special square pipe reach or even exceed the level of resistance welding cold-formed square pipe. Good comprehensive mechanical properties, weldability, cold and hot workability and corrosion resistance, and good low temperature toughness.There are many ways of ignition such as arc, electric spark, flame, strong current, high-temperature furnace, electron beam, laser, high-temperature radiation, microwave chemical furnace, etc.Malakatan,Qb square tube, has obvious hardening in the deep drawing process, resulting in many hard metal points, resulting in adhesion. Special products such as professional square tube, square rectangular tube, seamless square tube, galvanized square tube and galvanized tube are old brands, with advantageous price and guaranteed quality. It makes the surface of workpiece and die easy to scratch and wear, so tool steel for general die can not be used.During the pushing process of spot welding and repair welding elbows, there will be thinning, so manufacturers usually use thick spot pipes. If thin raw materials are used, the products produced must be unqualified. Generally, there are about wires thinned. If the technology is not good or the drawn pipe is used, the thickness is significantly lower than the standard.Cherebowetz,Square tube nonferrous metals, also known as non-ferrous metals, refer to metals and alloys other than ferrous metals, such as copper, tin,MalakatanHot dip galvanized square pipe, lead, zinc, aluminum, brass, bronze, aluminum alloy and bearing alloy. In addition, chromium, nickel, manganese, molybdenum, cobalt square tube, vanadium, tungsten, titanium, etc. are also used in industry. These metals are mainly used as alloy additives to improve the performance of metals. Tungsten, square tube titanium molybdenum,MalakatanRectangular hot dip galvanized square pipe, etc. are mostly used to produce cemented carbide for tools. The above non-ferrous metals are called industrial metals. In addition, there are precious metals: platinum, gold, silver and rare metals including radioactive square tubes.Purpose of square tube the purpose of square tube includes construction, machinery, steel construction and other projects, shipbuilding, solar power generation support, steel structure engineering electric products ( pieces)Spraying (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.

For transportation: water supply, drainage, sewage treatment engineering, mud transportation, marine water transportation.Material of square tube: q Q (Mn), #, alloy steel, stainless steel.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.index,Functional index analysis of qb square tube - commonly used are Brinell angle (HB) Rockwell angle (HRC) and Vickers angle (HV) of qb square tube. Angle is a gauge needle to weigh the soft and hard level of metal data. The angle method is rarely used to determine the internal angle in the current life. It uses the metal data surface tested under the fixed load of the indenter with a certain number and shape to determine its angle value according to the level of the object.Normalized: A. pearlite steel; b. Bainitic steel; c. Martensitic steel; d. Austenitic steel.The first is to remove the rust of the square tube. When removing the rust of the square tube, the steel wire brush is mainly used to polish its surface, which can effectively remove the loose or rusty rust on the surface of the square tube.

Square tube is made of different materials. It needs qualified inspection by relevant staff before leaving the factory. Square tube has a wide range of uses. Its main field is not only the construction industry, but also can be seen everywhere in our daily life. The service life of square tubes is mainly affected by surface treatment. I will explain the specific operations of surface treatment of square tubes.manufacturer,The square tube for fluid transportation (gbt-) is a general square tube for transporting water,MalakatanHot rolled seamless square tube, oil, gas and other fluids.Forging has many advantages in improving the plasticity of qb square tube and improving the quality of steel, because the cast state of forged metal can be broken when forging qb square tube. Therefore, there are forging workshops in some qb square tube factories.Section shape classification square tubes are classified according to section shape: simple section square tubes & mdash& mdash; Square tube, open square pipe, corrugated square pipe and special-shaped square pipe square pipe is divided into hot-dip galvanized square pipe, electro galvanized square pipe, oil coated square pipe and pickling square pipe according to surface treatment. Square pipe is classified according to purpose & mdash& mdash; Square tubes for decoration, machine tools and equipment, machinery industry, chemical industry, steel structure, shipbuilding, automobile, steel beam and column and special purpose are classified by wall thickness & mdash& mdash; Super square tube,Square tube has a wide range of application fields. Its main field is the construction industry, the production design of square tube hole is also different. Next, and cast the liquid cast iron into a cast square pipe. This kind of cast iron is called cast iron.
