I-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.Plan scheme : Martensitic chromium alloy pipe and chromium alloy pipe with Cr composition exceeding %,WilwardHow much is 304 seamless pipe per ton, without high carbon steel and high chromium alloy pipe. The aqueous solution contains % sodium cyanide % ~ % (volume ratio), the solution temperature is ~ ℃, and the solution time is min.Wilward,Wilward60 seamless pipe price, The rapid popularization and application of cold drawn ribbed bars and hot rolled grade III bars in China provides a good material basis for the development of welded mesh. The formal implementation of welding net product standards and application procedures has played a positive role in product quality and accelerating popularization and application.I-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.Wete,When we carry out different projects, we must use different raw materials, which can ensure the quality of the project. In many kinds of data, alloy pipe is widely used. In many projects we will apply it, so it is very popular in the field. When people carry out the construction of alloy pipe project, there are many things that must be paid special attention to. Let&#;s take you to know: Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time, and the waist is parallel to the roll axis.H-shaped steel groove is deep and thick, and can withstand forces in two directions.

I-beam features: the content of chromium carbon alloy is -%,WilwardWelded pipe, the hardness of chromium carbide alloy is V and the macro hardness is - HRCGalvanized pipe is a kind of light thin-walled steel pipe with hollow square section, also known as steel cold-formed profile. It is a section steel with square section shape and size, which is made of Q hot-rolled or cold-rolled strip or coil as the base material, cold bending and high-frequency welding. In addition to wall thickness thickening, the corner size and edge flatness of hot rolled extra thick wall galvanized pipe reach or even exceed the level of resistance welding cold formed galvanized pipe. Good comprehensive mechanical properties, weldability, cold and hot workability and corrosion resistance, and good low temperature toughness.Plan scheme : high carbon steel with carbon content exceeding .% and alloy pipe with chromium content not less than %How many?,Application characteristics of I-beamC - section steel is reliable and stable in stress, and is resistant to impact and vibration Moreover, and has a variety of C-section steel and size selection to ensure its flexibilityH-section steel

Direct rolling pass system. The direct rolling pass system refers to the pass system in which the two open legs of the I-beam pass are on the same side of the roll axis at the same time, and the waist is parallel to the roll axis.Discount, The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge. When the mesh reinforcement on both sides of the beam is different, the reinforcement on both sides extends into the beam, and the reinforcement anchorage length is required.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, 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.WilwardKey technical characteristics of alloy pipe:Dry processing technology: after passivation treatment, parts shall be dried with air compression or hot gas, or drying treatment or air drying can be selected.I-beam, also known as steel beam
