Purpose of square tube the purpose of square tube includes construction, machinery, steel construction and other projects, shipbuilding solar power generation support, steel structure engineering, electric products ( pieces)The disadvantage of solid bending is that it has tensile thinning effect. The actual bending will produce tension at the bending point, and the tensile effect will shorten the longitudinal length of the bending line; The metal at the real bend will become thinner due to stretching.Asenuogler,The surface compressive stress characteristics of the square tube will be obtained after isothermal quenching.Tool derusting mainly uses tools such as steel wire brush to polish the surface of square pipe, which can remove loose or oxidized scale, rust, welding slag, etc. The derusting of manual tools can reach grade SA and that of power tools can reach grade SA. If the square pipe surface is firmly attached with iron oxide scale, the derusting effect of tools is not ideal and can not reach the anchor depth required by construction.Banjo Gore,Square tube is made of different materials. It needs qualified inspection by relevant staff before leaving the factory. Square tube has a wide range of uses. Its main field is not only the construction industry, but also can be seen everywhere in our daily life. The service life of square tubes is mainly affected by surface treatment. I will explain the specific operations of surface treatment of square tubes. special shaped square pipe is the general name of square pipes with other cross-section shapes except circular pipe. According to the different cross-section shape and size of steel pipe, it can be divided into special-shaped square pipe with equal wall thickness (code D), special-shaped square pipe with unequal wall thickness (code BD) and special-shaped seamless steel pipe with variable diameter (code D) These special-shaped large-diameter qb square tubes are widely used in various structural parts,Asenuogler10mm square tube, tools and mechanical parts. Compared with circular tubes, and have large bending and torsion resistance, which can greatly reduce the structural weight and save steel. Square tubes are an indispensable part of construction workPrinciple of cold drawing strengthening: the lattice defects of steel increase during plastic deformation, and the serious distortion of defect lattice will hinder the progress and slip of lattice so the yield point of steel increases and the plasticity and toughness decrease. Due to the internal stress in plastic deformation, 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.Stainless steel qb square pipe for fluid transportation, Standard No.: gbt-. The representative materials are Cr crni crni cr crninb, crnimo, etc., which are mainly used to transport low-pressure corrosive media.Hundreds of degrees Celsius,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, because the strength is also divided into tensile strength, 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.Comprehensive classification ordinary steel A. carbon structural steel: (a) Q (b) Q (b); (c) Q( C); (d) Q( B); (e) Q.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,AsenuoglerSquare pipe with galvanized strip, and there are cracks after rolling.

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,AsenuoglerGalvanized pipe, 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!plan,The strength, plasticity and hardness discussed above in fatigue QB are the indicators of the mechanical properties of metals under static load. In fact, many machine parts work under cyclic load, under which fatigue will occur.There are some defects in qb square tube during stretching, which are caused by the following reasons. The common main reasons are as follows: select the appropriate qb square tube material, and the commonly used materials in austenitic qb square tube are CrNiTi and CrNiTi. During deep drawing, CrNiTi is more stable than CrNiTi and has better crack resistance. Therefore, CrNiTi material should be selected as much as possible.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.Asenuogler,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.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, because the strength is also divided into tensile strength 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, 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.: it refers to the processing of square tube, which places metal in a closed Jane and applies pressure at the end to extrude the metal from the specified die hole to obtain finished products with the same shape and size. It is mostly used to produce non-ferrous metal materials. Square tube ferrous metal, steel and non-ferrous metal. Before introducing the classification of steel, briefly introduce the basic concepts of ferrous metal, square tube steel and non-ferrous metal.
