2022-07-24 13:17:09I-beam, also known as steel beam, is a long strip of steel with I-shaped section. I-beam is divided into ordinary I-beam and light I-beam. It is a section steel with I-type section shape.C - section steel is reliable and stable in stress, and is resistant to impact and vibration Moreover, it has good versatility and combination, and has a variety of C-section steel and size selection to ensure its flexibilityCardenas, Quality requirementsAll the cracks occur at -mm away from the edge below the alloy pipe, and the macroeconomic orientation is vertical to the cold rolling orientation, showing a 'high mountain' shape.Surany,The general alloy pipe with improved performance is variable and has high application value. The alloy pipe contains more Cr and is heat resistant Low temperature resistance Corrosion resistance. There is no aluminum alloy in plain carbon seamless steel pipe, not very little aluminum alloy, and the alloy pipe is used in crude oil Aerospace Chemical plant Power engineering heating furnace. Because the physical properties of alloy tubes are easy to change and adjust.→ wide flange and large lateral stiffness. Strong bending resistance.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.
Alloy pipe is a spiral seam seamless steel pipe, which is made of hot-rolled strip steel coil, often processed by warm extrusion and welded by automatic double wire double side arc welding process. The alloy pipe sends the hot-rolled strip steel to the welded pipe unit,CardenasHow much is a meter of 2-inch galvanized pipe, and the hot-rolled strip steel is extruded through multiple passes. The hot-rolled strip steel is rolled slowly to produce annular pipe material with open mouth gap. Adjust the reduction amount of the extrusion roll to control the welding gap at ~ mm and make both sides of the weld flush.Galvanized pipe: the zinc layer of cold galvanized pipe is an electroplating layer and the zinc layer is separated from the steel pipe substrate. The zinc layer is very thin. The zinc layer is simply attached to the steel pipe substrate and is easy to fall off. Therefore, its corrosion resistance is poor. In new homes, it is forbidden to use cold galvanized pipes as water supply pipes.Due to the unique performance of I-beam, I-beam has successfully solved the problem of serious equipment wear in many industries.agent,Cardenas20# seamless pipe factory,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.Performance parameters and application scope of I-beam Peak crack
The system is mainly composed of control box, finishing roller, pre leveling unit, finishing unit and straightening unit.Click to view,The sodium cyanide passivation treatment of alloy pipe can be divided into four categories. Before passivation treatment, the surface of alloy pipe shall be clear of oil stains, pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned, which determines that the color of the surface layer has no change before and after passivation treatment, and the reproducibility of the solution is good.Steel pipes can be classified by their models:C-section steel has uniform zinc layer, smooth surface, strong adhesion, no zinc scar, no zinc leakage and high dimensional accuracy. All surfaces are wrapped by zinc layer, and the zinc content on the surface is usually -g /? It has long service life, corrosion resistance and durability. It is a kind of stronger protection.Cardenas,Key technical characteristics of alloy pipe: Hot stamping. Fix the plan product workpiece or preformed vacancy on the rotating journal, with the wheel working pressure vacancy, radial wheel. After one or several solutions there can also be a variety of methods for the whole process of hollow thick wall rotating body products. Products manufactured by high-precision processing method have excellent physical properties, mold shell and software requirements specification scope, which are very simple, very easy to be replaced, and relatively low product cost. The processing time is not long enough, the processing capacity is not high, the total length of processing pipeline is limited
