Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different so it can only be directly used for members bent in the plane of their web or form lattice stressed members.I-beam can only be used for beam,Seamless pipe is made of steel block or solid pipe blank while H-beam can be used for load-bearing column of structure.Santiago, and then made by hot rolling, cold rolling or cold dial. Seamless pipe plays an important role in Chinas steel pipe industry. Seamless pipe production processes are relatively rich, generally according to the corresponding steps of processing and production.The specification of pass design I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is. The types of I-beam include hot-rolled ordinary I-beam, light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~, expressed as No. ~ No., and the inclination of inner wall of leg is : The pass system of rolled I-beam includes direct pass system, cross pass system and mixed pass system. In addition, I-beam can also adopt special rolling method.Santa-Lucia-Milpas-Altas,I-beam has the dual properties of high hardness and toughness materials. Compared with other engineering wear-resistant materials in China, such as various alloy steel plates, cast wear-resistant plates, rubber, polyurethane, etc., it has irreplaceable comprehensive excellent properties.Function of I-beam: where is I-beam mainly used?→ compared with the concrete structure, the I-steel structure can increase the service area by %,SantiagoHigh pressure alloy pipe, reduce the self weight of the structure by % - %, and reduce the structural design internal force.
Aiming at the connective tissue and texture produced in stainless steel plate Position and other crystal defects are generally removed by heat treatment processes such as quenching or quenching. The effect of quenching is to optimize the crystal, eliminate structural defects, reduce strength, improve plastic deformation, and also conducive to cold drawing. In the production and manufacture of cold drawn alloy pipe, quenching machinery and equipment cannot be lacked. Therefore, the formulation of appropriate annealing process is a necessary condition to ensure that the alloy pipe mechanism meets the standard and the commodity does not crack. If the manufacturer in order to better one sidedness, reduce the product cost and reduce the quenching process, it will eventually lead to bad harm to the product quality.In view of the current market environment, especially in terms of construction or equipment manufacturing technology, the position of galvanized pipe is still relatively large. It is precisely because of this strong position that we can see this kind of building material in all walks of life, even in a field that seems to have little contact. It will be applied in many construction projects. At the same time, even in the depressed environment of the steel industry, the application situation and utilization rate of this kind of pipe are very high.Advantages of using I-beam: reduce maintenance cost, reduce downtime, improve equipment operation rate, reduce wear, reduce equipment capacity and increase power consumptionmarket price, Judged as failing.I-beam is an economic section high-efficiency profile with more optimized section area distribution and more reasonable strength weight ratio. It is named because its section is the same as the English letter 'H'.Generally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.
Judged as failing.Honesty and mutual benefit, Small longitudinal crack Quality requirementsAccording to the national standard of hot rolled H-section steel in China (GB / t-, H-section steel is divided into narrow flange wide flange and steel pile, whose codes are Hz, while wide flange H-section steel and H-section steel piles are suitable for axial compression members or compression bending members. Compared with H-section steel, W, IX and iy are not as good as H-section steel under the premise of equal weight.Santiago, dead end welding of strip steel and circumferential seam. For the spiral welding of steel for the transportation of flammable general liquids, yibai%sx ray or ultrasonic testing shall be carried out. For the spiral welding of alloy pipes for the transportation of water,Santiago15CrMoG seamless alloy pipe,SantiagoSpiral welded pipe wholesale, wastewater, gas, heating steam and other general liquids, X-ray or ultrasonic testing sampling inspection (%) shall be carried out.The import and export order of I-beam is generally based on the specifications required in use after determining the corresponding carbon structure steel (or low alloy steel) steel grade. Except for the specification number
