Japanese standard square tube, British standard square tube, American standard square tube, European standard square tube and non-standard square tube.The inspection items, sampling quantity, hot-rolled square tubes can be sampled in batches according to the rolled root array.MenAn,After perforation, the round tube blank is successively rolled by cross rolling,MenAnGalvanized square pipe stainless steel square pipe, continuous rolling or rolling. Take off the pipe after sizing. The conical drill bit of the sizing machine rotates into the steel embryo at high speed to form a steel pipe. The inner diameter of the steel pipe is determined by the outer diameter length of the sizing machine bit. After sizing, the steel pipe enters the cooling tower for water spray cooling. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is taken by the beltHigh quality steel (P & le; .%, S & le; .%)AnkazoaboThe principle of straightening machine is that a disc is divided into two sides to clamp round steel straight lines. Professional square tube, square rectangular tube, seamless square tube, galvanized square tube, galvanized tube, high price, service, on-site settlement, honest operation! The edge is one with radius r, and the other outer edge must be two equal diameters with radius R. The diameter of the reinforcement to be straightened is D, and the center distance between them is adjusted to R + R + D.After cold drawing and aging treatment, the yield point is improved, the tensile ultimate strength is also increased, and the plasticity continues to decrease. Due to the reduction of internal stress during aging, the modulus can be basically restored. According to this principle, cold drawing or cold drawing of reinforcement or low carbon steel wire rod is often carried out on site or prefabricated component factory, qb square tube, qb square tube, QB square tube, QB square tube and hot-rolled right angle square tube are of good quality and excellent quality. We have become a supplier of many enterprises. Qb square tube and I-beam are two products with different shapes. Under the condition of the same material, the bearing capacity of steel is the same, the specific selection of steel depends on the requirements of the project. Square tube practical application square tube for structure (gbt-) is a square tube for general structure and mechanical structure.

The reason why the surface of fake and shoddy materials is easy to crack is that its blank is adobe with many air holes. During the cooling process, the adobe has cracks due to the action of thermal stress, and there are cracks after rolling.Classification of surface treatment square pipe is divided into hot-dip galvanized square pipe, electro galvanized square pipe, oiled square pipe and pickled square pipe according to surface treatment.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.OK or not?,The second is to clean the surface of the opposite pipe. When cleaning the opposite pipe, the surface should be cleaned with solvent or emulsion. Square pipes of various specifications, square rectangular pipes, seamless square pipes, galvanized square pipes, galvanized pipes are supplied in time and cost-effective. They have become the preferred brand of many wire products. Welcome to buy! It is used to remove oil and dust. It is only suitable for removing grease and dust on the surface of square pipe, which can not remove rust and oxide scale. Therefore, it can only be used as an auxiliary means in production.Square tube is a very good steel in economic construction. There are many kinds and principles of cold drawing. You may still have a lot of insufficient understanding of the cold drawing principle of each other's pipe. Next, I'll lead you to learn its cold drawing principle.Empty bending empty bending is the bending moment formed in one direction between the outer roll and the outer wall of the tube blank to bend the strip. Empty bending will compress the bending line, the compression effect will lengthen the bending line longitudinally, and the metal at the bending will accumulate and thicken, which is the compression thickening effect of empty bending.

Hot dip galvanized square pipe is widely used, mainly in curtain wall,MenAnGalvanized square tube rectangular,MenAnThin wall galvanized pipe, solar power generation support, construction, machinery and steel structure engineering, especially in curtain wall, machinery and construction. The effect of cold galvanized square tube is far from that of hot galvanized square tube; How to distinguish hot galvanized square pipe from cold galvanized square pipe?Latest quotation,Structural stainless steel square pipe (gbt-) is a hot-rolled (extruded, expanded) and cold drawn (rolled) square pipe made of stainless steel for corrosion-resistant pipes, structural parts and parts widely used in chemical, petroleum, light textile, food, machinery and other industries.Square tube with complex section: flower shaped square tube, open square tube, corrugated square tube and special-shaped square tube.According to smelting classification and furnace type, A. open hearth steel: (a) acid open hearth steel; (b) Alkaline open hearth steel.MenAn,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.It should be noted that the position of the disc from the calibration line can be adjusted according to the reinforcement diameter, and R and R can be equal or different.Square tube nonferrous metals also known as non-ferrous metals, refer to metals and alloys other than ferrous metals, such as copper, tin, 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, etc. are mostly used to produce cemented carbide for tools. The above non-ferrous metals are called industrial metals. In addition, gold, silver and rare metals, including radioactive square tubes.
