Requirements of alloy tubes for low and medium pressure boilersDry processing technology: after passivation treatment, parts shall be dried with air compression or hot gas, or drying treatment or air drying can be selected.Sandbey,Cold.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, 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.Casoria,Plan scheme : for high carbon steel with carbon content of more than .% and high chromium alloy pipe with chromium content of no less than %,SandbeyAlloy20 alloy pipe,SandbeyHow much is a meter of welded pipe, the interval is min.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.H-section steel belongs to high-efficiency and economic cutting profile (other cold-formed thin-wall section steel, profiled steel plate, etc.). Due to the reasonable section shape, they can make the steel give more play to its performance and improve the cutting capacity. Different from ordinary I-type, the flange of H-section steel is widened, and the inner and outer surfaces are usually parallel,SandbeyHow many tons of reinforcement per square meter, so it is convenient to connect with other components with high-strength bolts. Its size composition is reasonable, series and models are complete, which is convenient for setting

Its size composition is reasonable, series and models are complete, which is convenient for settingGalvanized pipes shall be stored in dustproof to keep clean and new . As a professional manufacturer of galvanized pipe, we have produced galvanized pipe products for many years. Welcome friends who need to buy.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.install,It is a potential rolled strip steel with rectangular section for general purpose. It is very common on construction sites. Its specifications are expressed in thickness and width. At present, most of the flat steel on the market are finished steel, which can be used ready-made for components, ladders, and the relevant limit accuracy or appearance change is not easy to change.The flange of H-beam is of equal thickness including rolling section and combined section composed of three plates welded. All I-beams are rolled sections. Due to poor production technology, the inner edge of the flange has a slope of : The rolling of H-beam is different from that of ordinary I-beam. Only one set of horizontal rolls is used. Because its flange is wide and has no inclination (or the inclination is very small), a group of vertical rolls must be added for rolling at the same time. Therefore, its rolling process and equipment are more complex than ordinary rolling mills. The maximum height of rolled H-section steel that can be produced in China is mm, which exceeds the welded composite section.

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, That is,What are the uses of I-beam? Application of galvanized pipeI-beam is a kind of economical section steel with better section mechanical properties. Its characteristics are as follows:Sandbey,Generally, there are many passivation methods for alloy tubes the common ones are high temperature passivation or sodium cyanide passivation.Defects of alloy pipe and solutions: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.
