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 flexibilityThe specification of I-beam is expressed in cm of waist width. For example, the waist width of No. I-beam is cm. The types of I-beam include hot-rolled ordinary I-beam Light I-beam and wide parallel leg I-beam (H-beam). The waist width of hot-rolled ordinary I-beam in China is ~ mm, expressed as No. ~ No. and the inclination of inner side wall of leg is : The pass system of rolled I-beam includes direct rolling pass system, cross rolling pass system and mixed pass system. In addition,niclol 2205 duplex steel welded pipe, I-beam can also adopt special rolling method.niclol , the zinc coating forms white,niclol How much is the price of I-beam per meter, colorful and military green, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.Iguazu,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 ℃ ~ ℃)Alloy pipes can be used for heating (cooling) projects.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.

Using alloy pipe to produce ring parts can improve the utilization rate of raw materials, simplify the production and manufacturing process, and save raw materials and production and processing construction time such as roller bearing ring throwing Nowadays, seamless steel pipe has been widely used to produce hydraulic jack sleeve.Filling: welded pipe is welded by electric welding of hot-rolled strip steel, so its influence was not as high as that of seamless steel pipe.Xhy- series high hardness alloy I-beam; Undertake drawings and process wear-resistant pipes( Φ ≥mm); Undertake the processing and production of vulnerable parts of cement machinery; Welding technology consultation and service; The wear-resistant layer of alloy wear-resistant plate of high chromium heap welding flux cored wire series is mainly high chromium, as well as manganese, molybdenum, niobium, francium and other components. The alloy carbide formed has strong stability at high temperature.Online consultation,It is widely used in various fields of national economic construction, such as buildings, bridges, power stations, oil drilling platforms, vehicles, highways, subways, steel structure plants and large warehousesAfter the passivation treatment of alloy pipe, it is clearly proposed that water cleaning shall be carried out immediately after the aqueous solution, ~ times of water cleaning, and then chromic acid closed solution shall be carried out. Chromic acid solution must be carried out h after the subsequent water cleaning of metallographic structure and austenitic alloy pipe. Chromic acid aqueous solution (mass ratio) is % ~ %, the solution temperature is ~ ℃, and the solution time is min. Then dry.Difference and application description between H-beam and I-beam

Key technical characteristics of alloy pipeMeticulous workmanship,→ the two surfaces of the flange are parallel to each other, making it easy to connect, process and install.There are many types of galvanized pipes, mainly including cold plated seamless pipes and hot-plated seamless pipes. But now the previous one is no longer used. The hot-dip seamless tube is still in use. Hot dip galvanized pipe is mainly used for steel pipes with low pressure fluid such as water and gas. When in use, if in normal working environment, and it has been used safely for about years. It can be seen that its service life is very long. Of course, when purchasing, we should also find regular manufacturers to order. Only in this way can we achieve this service life. As long as the galvanized pipe is cleaned after pickling, it is basically cleaned in ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank. In order to ensure the quality, electro galvanizing will not be used. There are also some small enterprises in the market. They will use electro galvanizing in production. In this way, although it is much cheaper in price. However, the quality is very good when used and it is also easy to have problems.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, water supply equipment, or pipeline, heat and national defense industrial pipeline system software of petrochemical pipeline system, alloy steel pipe stimulates important effects.niclol ,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, and their metal properties are controlled by changing the metallographic structure on the surface or inside of the material. During the heating and cooling process of structural welded steel pipe workpiece due to the inconsistency of cooling speed and time between the surface and the core, the temperature difference will be formed, that is, thermal stress.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 flexibilityI-beam is a long strip steel with groove section, which belongs to carbon structural steel for construction and machinery. It is a section steel with complex section,niclol Large diameter 15CrMoG alloy pipe, and its section shape is groove shape. China&#;s imports of I-beams are greater than its exports. The main producing areas are Tangshan Iron and steel, Shangang, huangte, Maanshan Iron and steel, Xuanhua Iron and steel, Japan iron and steel, etc.
