Among them, qb square tube is divided into: (a) by process & mdash& mdash; Arc welded square pipe, resistance welded square pipe (high frequency and low frequency), gas welded square pipe and furnace welded square pipe (b) are divided by weld & mdash& mdash; Straight seam welded square pipe spiral weldingPig iron refers to the product made by smelting iron ore in blast furnace. It is mainly used for steelmaking and square casting. Put the cast pig iron in the melting furnace to obtain cast iron (liquid), and cast the liquid cast iron into a cast square pipe. This kind of cast iron is called cast iron.El palaiso,The square tube can be sprayed with fluorocarbon paint, which needs some treatment before spraying.Steel used & mdash& mdash; Such as bridge steel, ship steel, boiler steel, pressure vessel steel, agricultural machinery steel etc.Aguascalientes,Square tube structural steel A. mechanical steel: (a) quenched and tempered structural steel; (b) Surface hardening structural steel: including carburized steel, ammoniated steel and surface quenching steel; (c) Easy to cut structural steel; (d) Steel for cold plastic forming: including steel for cold stamping and steel for cold heading.The 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, and the center distance between them is adjusted to R + R + D.B. tool steel: (a) carbon tool steel; (b) Alloy tool steel; (c) High speed tool steel.

If the test results of square tubes fail to meet the provisions of product standards and the other outer edge must be two equal diameters with radius R. The diameter of the reinforcement to be straightened is D, the unqualified ones shall be selected, the batch of square tubes shall not be delivered. If the following inspection items fail to pass the preliminary inspection, re inspection is not allowed: A. There are white spots in the low magnification; b. Microscopic.Square pipe, the steel pipe whose ratio of outer diameter to wall thickness is less than is called square pipe. At present, the square tubes produced by qb square tube factory are mainly used in tap water engineering,El palaisoGalvanized square pipe manufacturing equipment, petrochemical industry, chemical industry, electric power industry,El palaiso4-inch galvanized round pipe, agricultural irrigation and urban construction. For transportation: water supply and drainage. For gas transmission: gas, steam and liquefied petroleum gas. For structure: for punchingStage ( & mdash; )ranking, which can be used as solder to weld special-shaped materials in order to overcome the mismatch of chemical, mechanical and physical properties between base metals.

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.Convenient and efficient,Square tubes for petroleum cracking (gb-) are furnace tubes, heat exchangers and pipeline square tubes suitable for petroleum refineries.First, remove the deposits on the surface of the square pipe surface with copper wire brush. Use the perfume oil or other scrubbing oil on the surface layer, or use phosphate or chromate solution, brush, spray or dip coating. After the fixed reaction time, rinse the acid solution with plenty of fresh water on the surface.Brinell hardness (HB), Rockwell hardness (HRC) and Vickers hardness (HV) are commonly used.El palaiso,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.The other is designed with deformation angle, which can be regarded as DEG from round tube to square tube; To & deg; The bending deformation of angle, considering the influence of dimensional accuracy and metal work hardening, the distribution of deformation angle is usually larger at the beginning and middle passes, and then gradually decreases. In the pass formed directly by arc intersection, the fillet part of the pipe blank cannot be filled with the pass, so the pass perimeter is different from that of the pipe blank. In order to ensure the dimensional accuracy, the fillet part of the pass needs to be corrected and calculated. Therefore, this method has higher design accuracy than other methods. However,El palaisoHow much is 200 galvanized square tube, due to the large amount of iterative calculation, this method is more suitable for pass design by computer. If you use a frame that deforms both horizontally and vertically, you can directly use the deformation angle & theta; Pass design.For gas transmission: gas, steam and liquefied petroleum gas.
