Square tubes have different functions and different characteristics. Square tubes of various specifications, square rectangular tubes, seamless square tubes, galvanized square tubes and galvanized tubes are welcome to waste merchants, 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.Zinc layer thickness: there is a great difference between cold galvanized square pipe and hot galvanized square pipe in galvanizing process; Cold galvanized square pipes are prone to & ldquo; Electric burning & rdquo; The color of this part is gray and the zinc layer is thick. It is easy to form a current dead angle at the corner, resulting in an under current area. The zinc layer at this part is thin, and there is no zinc layer attached to the cold galvanized square pipe. The cold galvanized square pipe has no zinc lump and caking as a whole, but the overall zinc layer is thin, and the thickness of the outer wall zinc layer is μ m-μ m. The and outer walls of the hot-dip galvanized square tube are attached with zinc layer, and there will be water marks and a few zinc tumors, but the overall zinc layer is thick, and the thickness of the zinc layer on the inner and outer walls of the square tube is -mu; M above. The nature of QB square tube!Chadecha,Application of square tube products: for mechanical equipment, solar energy equipment, steel structure, automobile parts, chemical and electrolytic methods are usedSanta Coloma de Gramenet guardrail and ship internal structure.Generally,The difference between square pipe and seamless steel pipe the main feature of seamless steel pipe is no welding joint and can withstand large pressure. The product can be very rough as cast or cold drawn parts.The disadvantage of empty bending is that when the upper side and side are synchronously empty bending the forming force is easy to exceed the critical point due to the pressure generated by the upper roll and the lower roll at the same time, resulting in edge instability and concave, and will also affect the stable operation and forming quality of the unit. This is also the different characteristics of qb square tube and round tube empty bending. The concept of square tube: square tube is the pressure processing of ingot, billet or square tube Make materials of all shapes,ChadechaSpecification and model of galvanized pipe,ChadechaGalvanized square pipe rectangular pipe, sizes and properties we need.We all know very well. Therefore, the quality of square tubes will directly affect the development of the construction industry. What if we can make the service life of square tubes longer? Here, we also need to ask the personnel of the square tube manufacturer for instructions, and use ingenious methods to prolong the service life of the square tube, so that the square tube can bring us greater help in life.

Stainless steel square tube for fluid transportation (gbt-) is a hot-rolled (extruded, expanded) and cold drawn (rolled) square tube made of stainless steel for fluid transportation.Elongation after square tube breaking (& sigma;): in the tensile test, the percentage of the length increased by the gauge length of the sample after breaking and the length of the original gauge length is called elongation. In & sigma; Expressed in%.Welding is a synthetic gradient material, 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.Sincere service,Steel pipe for geological drilling (yb-) is a steel pipe used by geological departments for core drilling. It can be divided into drill pipe, drill collar, core pipe, casing, sedimentation pipe, etc.The strength, plasticity and angle discussed later are the machine function indicators of metal under static load. In practice, many mechanical machines are under repeated load, and the whole opportunity is tired in this environment.High density may not be obtained by simple pressurization, metal ceramic and metal metal welding.offerChange to square pipe: generally, the strip steel is unpacked,Chadecha4-inch galvanized square pipe, leveled, crimped and welded to form a round pipe, and then cut into the required length. Stage ( & mdash; )When the square tube is covered the surface of the square tube shall be ventilated to avoid the collection of water vapor on the surface due to difficult volatilization.Reinforcing phases such as reinforcing particles, short fibers and whiskers can be added to the solder to form composites.Chadecha,There are sets of MPM and sets of MRK pipe mills in the world. Strength refers to the function of qb square tube data being destroyed under static load (appropriate plastic deformation or fracture). Because the action forms of load include tension, contraction, meandering, shear and so on, compressive strength, flexural strength, shear strength and so on. There is often a definite connection between various strengths. Long term square tube, square rectangular tube, seamless square tube, galvanized square tube and galvanized tube have no turnover to avoid price difference, and the price is % higher than the market price! The price of more than one ton is higher! In normal use, tensile strength is often taken as the fundamental strength gauge needle.Hundreds of degrees Celsius, which can save energy.The difference between hot-dip galvanized square pipe and cold-dip galvanized square pipe is mainly from the following aspects: the appearance of hot-dip galvanized square pipe is slightly rough compared with cold-dip galvanized square pipe; The appearance of cold galvanized square pipe is smooth and bright.
