H-section steelAccording to the theory of steel structure, the I-beam flange should be stressed, that is, the I-beam should be standing rather than lying down.Wave ordinary,Precautions for galvanized pipe storageApplication characteristics of I-beam:Menongue, H-section steel is an economic section steel with better mechanical properties than I-section steel. It is named because its section shape is the same as the English letter 'H'. The flange of hot rolled H-beam is wider than that of I-beam, H-beam is lighter than I-beam.Generally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation. Hot stamping. Fix the plan product workpiece or preformed vacancy on the rotating journal, with the wheel working pressure vacancy, 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, specification scope, mold shell and software requirements, 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,Wave ordinary12CR2MOG alloy pipe, and the size of machinery and equipment is generally short.

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,Wave ordinaryHow much is 16# I-beam per meter, pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned, and the workpiece of alloy pipe products can be infiltrated into aqueous solution. The passivation treatment of the alloy tube in sodium cyanide transforms the surface layer into a very thin passivation treatment film, 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.The allowable deviation of vertical installation of galvanized pipe is mm per meter, and the allowable deviation above m is no more than mm. The allowable deviation of horizontally installed pipes is mm per meter.Stages needing attention in the production and manufacture of alloy tubesWork courses, 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,Wave ordinaryHow much is the steel bar binding wire per kilogram, and the waist is parallel to the roll axis.Pass designKey technical characteristics of alloy pipe:

Alloy pipes are widely used in building materials and the test standards of alloy pipes are also different. Alloy pipe has high hardness and can be used at many levels, most of which is prestressed reinforcement. Where plastic deformation is not specified but compressive strength is specified, such stainless steel plate can be applied.Workshop cost,H-section steel 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'. There is no slope on the inner side of the two outer edges of H-section steel, which is straight. This makes the welding and splicing of H-section steel simpler than I-section steel, better mechanical properties per unit weight, which is usually called thermal embrittlement Small longitudinal crackWave ordinary,Heating surface pipes economizers, superheaters, reheaters, pipes for petrochemical industry, etc. for high-pressure boilers (working pressure is generally above MPa and working temperature is between ℃ ~ ℃)I-beam: national standard * what is the wall thickness of I-beamThe utility model has the advantages that the axial force of the roll is small, the axial movement is small, the working inclined plane is not required, the pass occupies a small length of the roll body, and more passes can be matched under the condition of a certain length of the roll body.
