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, it is divided into wide medium and narrow flange I-beams. The specifications of the first two are -, that is, the corresponding height is -. At the same height, the light I-beam has narrow flange, also known as H-beam, is characterized by two parallel legs and no inclination on the inner side of the legs. It belongs to economic section steel and is rolled on four high universal mill, so it is also called 'universal I-beam'. Ordinary I-beam and light I-beam have formed national standards.Because alloy pipe is a very unique pipe fitting, we must use appropriate methods to carry out installation in the case of installation, so as to ensure the performance index of the data. Generally,IpatingaI-beam price quotation, when installing alloy pipes we will use some flanges and elbows to fix them, so as to ensure that the raw materials can be fixed very well. Therefore, when we carry out use, we must ensure the quality of flanges and elbows, so as to ensure the actual effect of alloy pipe assembly. If there are instrument panel components that must be assembled on the pipeline, they must be installed together.Ipatinga,Steel pipes can be classified by their models:What are the uses of I-beam?Esmeralda,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.Welded steel pipes need to be processed through various processes before application. The heat treatment of welded steel pipes is a very important link in the processing of welded steel pipes. Hot working is a metal hot working process in which metal materials are heated, insulated and cooled in a certain medium, due to the inconsistency of cooling speed and time between the surface and the core, the temperature difference will be formed, which will lead to uneven volume expansion and contraction and produce stress, that is thermal stress.Plan scheme : Martensitic chromium alloy pipe and chromium alloy pipe with Cr composition exceeding %, 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.
Alloy pipe is a very important way and type of seamless steel pipe. Its use is relatively common. It is widely used in various engineering projects, house construction and building decoration. Its fracture will always be found in the production,IpatingaHow much is the I-beam now,IpatingaHow much is a ton of No. 16 I-beam, manufacturing and key marketing of alloy pipe, That is, many stages of production and processing are not done well. Another is that the seasoning is not enough and the proportion of chemical molecules is wrong. There are all reasons. Pickling stainless steel pipe. When removing grease, rust prevention, spot welding, oxide layer, free iron and other dirt, the surface shall be treated with silver to evenly slow down the pickling surface, prevent metal corrosion and hydrogen embrittlement and inhibit fog production.The shape of small longitudinal crack on the surface of alloy pipe is less than mm The overall width is less than mm The depth is lower than .mm.quality,Dehydrogenation solution: the alloy pipe shall be dehydrogenated after passivation treatment to avoid alkali embrittlementAs shown in the name, I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination, generally :, which makes the outer flange thin and the inner flange thick. Therefore, the section characteristics of I-beam in the two main planes are very different, the structure of the I-beam has determined its torsional performance.Passivation treatment operation of alloy pipe
Requirements of alloy tubes for low and medium pressure boilersranking,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.The third is the welding machine, which must ensure reliable performance and meet the process needs; The welding machine must have qualified ammeter and voltmeter to ensure the correct implementation of welding process. The welding cable shall not be too long, and the welding parameters shall be adjusted when it is too long.The delivery length of I-beam is divided into fixed length and double length, and the allowable difference is specified in the corresponding standards. The length selection range of domestic I-beam is divided into -, - and - according to different specification numbers. The length selection range of imported I-beam is generally -.Ipatinga,C - section steel is reliable and stable in stress, can be accurately positioned, 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 flexibilityAs shown in the name, I-beam is an I-shaped section steel. The inner surface of the upper and lower flanges has an inclination generally :, the section characteristics of I-beam in the two main planes are very different, and it is difficult to give full play to the strength characteristics in application. Although the thickened I-beam has also appeared in the I-beam market, the structure of the I-beam has determined its torsional performance.The finished product has smooth surface, low friction coefficient, flatness error + / - mm / m length, wear resistance and maximum temperature of ℃
