H-beam is a widely used profile in steel structure buildings. It is different from I-beam. The first is the flange, and the second is that the inner surface of the flange has no inclination, and the upper and lower surfaces are parallel. The section characteristics of H-beam are obviously better than those of traditional I-beam, channel steel and angle steel.What is the stainless steel passivation of alloy pipe?Mandali, Whether the mesh size and wire diameter of electric welding mesh meet the standardsPlan scheme : high carbon steel with carbon content exceeding .% and alloy pipe with chromium content not less than %Brunei,Classification introductionAlloy pipe is a kind of seamless steel pipe. Alloy pipe is divided into structural seamless pipe and high-pressure heat-resistant alloy pipe. It is mainly different from the production standard and industry of alloy pipe. Annealing and tempering of alloy pipe changes its mechanical properties. Meet the required processing conditions. Its performance is higher than that of ordinary seamless steel pipe, its utilization value is higher,Mandali20# steel seamless pipe, the chemical composition of alloy pipe contains more Cr, and its performance of high temperature resistance, low temperature resistance and corrosion resistance. Ordinary carbon seamless tubes do not contain alloy components or have few alloy components. Alloy tubes are widely used in petroleum, aerospace, chemical industry, electric power boiler and other industries because the mechanical properties of alloy tubes change and are easy to adjust.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'.

When selecting I-beam in structural design, reasonable I-beam shall be selected according to its mechanical properties, chemical properties, weldability and structural size. I-beam is mainly divided into ordinary I-beam, light I-beam and wide flange I-beam. According to the height ratio of flange to web, medium and narrow flange I-beams.Square; Round; Fillet.Because all parts of I-beam are arranged at right angles I-beam has the advantages of strong bending resistance, simple construction, and has been widely used. The inner and outer sides of the flange of the I-beam are parallel or close to parallel, and the end of the flange is at a right angle, and the flange width is larger than that of ordinary I-beam with the same height of web, so it is also named wide edge I-beam.Inspection standard,Classification introduction 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.→ I-beam can be processed into T-beam, and honeycomb beam can be combined to form various section forms, which greatly meets the needs of engineering design and manufacturing.

Requirements of alloy tubes for low and medium pressure boilersEncyclopedic knowledge,Alloy steel pipe is a new type of seamless steel pipe connection pipeline. The selection of pipeline connection pipeline, whether it is fire water system software,Mandali20# seamless pipe manufacturer, water supply equipment,MandaliWhich is a good welded pipe manufacturer, or pipeline, heat and national defense industrial pipeline system software of petrochemical pipeline system, alloy steel pipe stimulates important effects.Keep the combustion supporting gas and use it reasonably to avoid fracture of the welding interface. Problems in the welding of steel wire mesh skeleton composite pipe are common, which should be prevented or solved.I-beam, also known as universal 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.Mandali Special rolling method. When it is difficult to roll the required I-beam by the usual rolling method for some reason, the special rolling method can be used to make full use of the skills of uneven deformation and pass design. For example, when the billet section is narrow and wide I-beam is required to be rolled, the wave rolling method can be used; for example, when the billet is wide and small I-beam is required to be rolled, the negative rolling method can be used Spread rolling, etc.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 ℃ ~ ℃) Judged as failing.
