Ludzas How much is 65 galvanized pipeAnalysis of the status quo of the parts processing industry

It is widely used in various fields of national economic construction, such as buildings, bridges, power stations, oil drilling platforms, vehicles, subways steel structure plants and large warehouses 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.Ludzas ,According to the shape of the product, special flour, welding or ordinary thread connection shall be used.The side length of I-beam is small and the height is large, so it can only bear the force in one direction.Prizren,So why is the alloy pipe easy to rust after being pickled and passivated by the software? 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, with large lateral stiffness and strong bending resistance. Under the same specification H-beam is lighter than I-beam.According 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.

So why is the alloy pipe easy to rust after being pickled and passivated by the software? Spiral seam submerged arc welded steel pipe (SY- for pressure fluid transportation is a spiral seam steel pipe used for pressure fluid transportation, which takes hot-rolled steel strip coil as pipe blank, often warm spiral forming and welded by double-sided submerged arc welding. The steel pipe has strong pressure bearing capacity and good welding . After various strict scientific inspections and tests, and can save the investment in laying pipelines. It is mainly used for transporting oil and natural gas.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, pickled and passivated. Passivation treatment can be carried out only after the surface is cleaned,Ludzas 10# steel seamless pipe, 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.supply,Ludzas How many software are there, what we need to do now is to improve the production technology level of China&#;s production process of C-section steel, and step up the formulation of relevant industry standards and inspection standards. C-section steel manufacturers should keep close contact with truck manufacturers and communicate more. In this way, it is more conducive for C-section steel manufacturers to produce C-section steel products suitable for truck industry.

Alloy tube is widely used in our daily life, which provides us with great assistance. So what industries are alloy tubes applied to? Let&#;s follow the steps of all manufacturers and have a look together:Installation works,The finished product has smooth surface, low friction coefficient, flatness error + / - mm / m length, wear resistance and maximum temperature of ℃ Cleaning: first, clean the grease,Ludzas Alloy pipe gh2747, dust and other substances attached to the surface of the galvanized pipe after cleaning.So why is the alloy pipe easy to rust after being pickled and passivated by the software?Ludzas , Small longitudinal crackThe crack mainly occurs at -mm from the edge of the alloy pipe. The shape is several parallel vertical cracks of different sizes. The regularity is that the thicker the specification and model of the alloy pipe is The wider the width, the more serious the disadvantages.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.
