The square tube for fluid transportation (gbt-) is a general square tube for transporting water, oil, gas and other fluids.Generally, chemical and electrolytic methods are usedAjax,AjaxHow much is a galvanized square tube,Now in many construction projects, we can see the shadow of qb square tube, because qb square tube is quite hard in hardness, and the performance and quality of deformation, stamping, cutting and other processing are based on hardness, which is also the guarantee of mechanical properties. Based on the above, it is very important to test the hardness of qb square tube., cold drawn tubes, tubes, etc. Hot rolled seamless tubes are produced on the automatic precision tube precision tube rolling mill. The solid tube blank is cut into the required length by removing surface defects, centering on the end face of the perforated end of the tube blank, and then sent to the heating furnace for heating. It is perforated on the piercing machine. At the same time, it rotates and advances continuously under the action of roll and plug, A cavity is gradually formed inside the pipe blank which is called the rough pipe, and then sent to the automatic pipe mill for continuous rolling. After the wall thickness is adjusted by the whole machine, and the diameter is determined by the sizing machine to meet the specification requirements. The continuous pipe mill is more advanced in producing hot-rolled seamless steel pipe. If you want to obtain seamless pipe with smaller size and better quality Cold rolling and cold drawing must be adopted, or the combination of cold rolling and cold drawing is usually carried out on the roll mill. The seamless pipe is rolled in the annular pass composed of variable section circular hole groove and fixed conical plug. Cold drawing is usually carried out on the single chain or double chain cold drawing machine, that is, and the perforated rod and rod move, This method can produce steel pipe with small diameter. In the building materials industry, the development of various pipes is different. Because of their different characteristics, there is a certain distance between pipes. Square pipe is one of many pipes in the building materials industry. It is formed after strip steel treatment. We need to understand the various characteristics of steel pipes. However, in the building materials industry, the development of various pipes is different. Because of their different characteristics, there is a certain distance between pipes. Square pipe is one of many pipes in the building materials industry. It is formed after strip steel treatment. The various characteristics of steel pipe need to be understood by everyone. However,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.Main uses of square tube: square tube is mainly used in tap water engineering the storage of steel pipe needs specific conditions.Bukhara, petrochemical industry chemical industry, electric power industry, agricultural irrigation and urban construction. It is one of the key products developed.Superior square tubular steel (both P and s ≤ .%)

Due to the increase of square tube production, there are more and more fake and shoddy square tubes in the market. How to distinguish the fake and shoddy square tubes? Let me teach you some points to distinguish the fake and shoddy square tubes.After aluminum deoxidation in molten steel,AjaxGalvanized steel square pipe, & omega; When (ALS) is .% ~ .%, calcium treatment can achieve better effect on the denaturation of Al.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.Application process,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.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, so the deformation angle & theta; It can accurately reflect the deformation degree of corners and edges. In the design process, considering the influence of dimensional accuracy and metal work hardening, the distribution of deformation angle is usually larger at the beginning and middle passes, 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, 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.Generally, chemical and electrolytic pickling are used for pickling treatment. Only chemical pickling is used for pipelines, which can remove oxide scale, rust and old coatings. Professional square tubes, rectangular tubes, seamless square tubes, environmentally friendly and economical! The products are exported to foreign countries and are deeply trusted. Sometimes they can be used as reprocessing after sand blasting and rust removal. Although chemical cleaning can make the surface reach a certain cleanliness and roughness, its anchor lines are shallow and easy to pollute the environment.

Square pipe is one of many pipes in the building materials industry. It is formed after strip steel treatment. The various characteristics of steel pipe need to be understood by everyone. However, due to the of steel pipe and other raw materials, the storage of steel pipe needs specific conditions.Highly recommended,Reinforcing phases such as reinforcing particles, short fibers and whiskers can be added to the solder to form composites.Tensile strength: - yield strength: & Ge; elongation: & Ge; mechanical properties of seamless pipe: tensile strength: - yield strength: ≥ elongation: & Ge; mechanical properties of seamless pipe: tensile strength: - yield strength: ≥ elongation: & Ge; mechanical properties of seamless pipe: tensile strength: - yield strength: ≥ elongation: & Ge; mechanical properties of seamless pipe: tensile strength: - yield strength: ≥ elongation: & Ge; square tube belongs to low alloy series. It is one of the materials of seamless steel pipe. In low alloy materials, ethylene phenolic and other coatings commonly used for square pipes, the surface of square pipes is generally required to reach near white grade (SA). Practice has proved that almost all oxide scale, rust and other dirt can be removed by using this derusting grade, and the depth of anchor grain can reach ~ & mu; m, which fully meets the requirements of adhesion between layer and square pipe The shot derusting process can meet the technical conditions of near white level (SA) with low operation cost and stable and reliable quality.Ajax,Cleaning solvent and emulsion can clean the surface of square tube to remove oil, grease, dust, agent and similar organic matter, but it can not remove rust, scale, welding, etc. on the surface of square tube, so it is only used as an auxiliary means in production.Viewing color: the color of the cold galvanized square tube is yellowish green
