With the improvement of production quality, the quality of square tubes is getting better and better. The quality of square tubes will affect our lives. Because the functions of square tubes are different, their characteristics and uses are different. I will introduce the characteristics and uses of square tubes in detail.Brinell hardness (HB), Rockwell hardness (HRC) and Vickers hardness (HV) are commonly used.Komapa,With the development of economy, there are a lot of demands for project construction, which leads to the continuous increase of square pipe. The of square pipe is more complex. Great efforts should be made in the selection of raw materials, structured treatment and so on.Hot dip galvanized square pipe is widely used, mainly in curtain wall, construction, machinery and steel structure engineering, 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?Newham,After chemical pickling, the square tube can be well protected by electrolysis. These are simple ways to prolong the service life of the square tube, We only need to treat according to these, so that the square tube can bring us great help in the use process. The cold galvanized square tube is the principle of cold galvanizing on the square tube used to make the square tube have corrosion performance. Different from hot-dip galvanizing cold galvanizing coating is mainly carried out according to the electrochemical principle. Therefore, it is necessary to ensure the sufficient of zinc powder and steel, resulting in electrode potential difference, so the steel surface treatment requirements are very high., 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,KomapaNational standard galvanized square pipe, the heated pipe blank is placed in a closed cylinder, 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,KomapaConnection mode of galvanized square pipe, 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, due to the of steel pipe and other raw materials, the storage of steel pipe needs specific conditions.C. special performance steel: (a) stainless and acid resistant steel; (b) Heat resistant steel; (c) Electric heating alloy steel; (d) Electrical steel; (e) High manganese wear resistant steel.

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.Mechanical property is an important index to ensure the end use performance (mechanical property) of square pipe, which depends on the chemical composition and heat treatment of steel. In the steel pipe standard, according to different service requirements, the tensile properties (tensile strength, yield strength or yield point, elongation), hardness and toughness indexes, as well as the high and low temperature properties required by users are specified.Functional index analysis of qb square tube - mechanical function of plastic square tube. Solid bending, as the name suggests, the inner and outer rollers and the inner and outer walls of the pipe blank are compacted in both directions.Quality documents,For gas transmission: gas, steam and liquefied petroleum gas.. 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.The strength, plasticity and angle discussed later are the machine function indicators of metal under static load. In practice,Komapa6-point galvanized square pipe, many mechanical machines are under repeated load, and the whole opportunity is tired in this environment.

Impact toughness the load acting on the machine part at a great speed by QB is called impact load, and the ability of metal under impact load is called impact toughness.Click to view,The square tube for fluid transportation (gbt-) is a general square tube for transporting water, oil, gas and other fluids.Shot blasting is a high-speed rotating impeller that throws small steel shot or small iron shot out and hits the surface of the square tube at high speed, so the oxide layer on the surface of the square tube can be removed. At the same time, the steel shot or iron shot impacts the surface of the square tube at high speed, resulting in lattice distortion and deformation on the surface of the square tube, increasing the surface hardness, which is the main reason for the surface deformation of the square tubeSquare tubes for low and medium pressure boilers (gb-) are high-quality carbon structural steel hot-rolled and cold drawn (rolled) square tubes for superheated steam tubes, boiling water tubes for low and medium pressure boilers of various structures and superheated steam tubes, large smoke tubes, small smoke tubes and arch brick tubes for locomotive boilers. Square tubes for high-pressure boilers (gb- is a high-quality carbon steel, alloy steel and stainless heat-resistant steel square tube for the heating surface of water tube boilers with high pressure and above. High pressure square tube for chemical fertilizer equipment (GB - is a high-quality carbon structural steel and alloy steel square tube suitable for chemical equipment and pipelines with working temperature of - ~ ℃ and working pressure of ~ mA.Komapa,Ferroalloy is an alloy composed of iron and silicon, manganese, titanium and other elements. Ferroalloy is the raw material for steelmaking. It is used as deoxidizer and alloy element additive for steel in square tube steelmaking.Impact toughness the load acting on the machine part at a great speed by QB is called impact load, and the ability of metal under impact load is called impact toughness.Square tubes have different functions and different characteristics. Square tubes of various specifications square rectangular tubes, seamless square tubes, industries, enterprises and power departments to visit and negotiate! Oxidation will also occur on the surface of square tubes after long-term use. What should we do if oxidation occurs? Let me give you a detailed introduction on how to remove square tubes Oxide scale.
