Small longitudinal crackThe 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, 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.Nibai, Spiral seam high-frequency welded steel pipe (sy- for pressure fluid transportation is a spiral seam high-frequency welded steel pipe used for pressure fluid transportation, which takes hot-rolled steel strip as pipe blank often warm spiral forming and high-frequency lap welding method. The steel pipe has strong pressure bearing capacity and good plasticity, which is convenient for welding and processing; After various strict and scientific inspections and tests, the application is safe and reliable, the diameter of steel pipe is large, the transportation efficiency is high, and the investment in laying pipeline can be saved. It is mainly used for laying pipelines for transporting oil, natural gas, etc.Mixed Scabs are distributed periodically, and the situation after casting and rolling is significant through edge flame peeling crack inspection or billet scratch flame removal.Silang,Nibai15CrMo seamless alloy pipe,What are the requirements for alloy pipe construction accessoriesWhen it is used for ground heating and hot spring transportation, it can meet the requirements of refrigeration and achieve the practical effect of less damage. It is applicable to water conservancy engineering, mining and other industries to meet the provisions of cold, cold and corrosion prevention. In addition, which can not only save resources, but also reduce consumption, not occupy the natural environment, but also purify the environment. The transportation of gas can meet the requirements of long-distance transportation, prevent actual operation and maintenance, meet the requirements of thermal insulation and cold protection, reduce heating equipment unique and convenient installation, and reduce the construction cycle time of the project. On the whole, it is more convenient to use. It can also be used for the transportation of floor heating and hot springs.

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.Classification by end shapeI-beam is widely used in buildings or other metal structures.Total quality assurance, The small length of repair welding is mm; The raw material shall not exceed mm after grinding by welding edge.The shape of I-beam is similar to that of H-beam. What is the difference between them?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.

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.Pursuit of excellence,Because all parts of I-beam are arranged at right angles, I-beam has the advantages of strong bending resistance, simple construction, cost saving and light structural weight in all directions, 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, so it is named parallel flange I-beam. The web thickness of I-beam is smaller than that of ordinary I-beam with the same height of web, 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.Wire sleeve: it is also a general carbon steel welded steel pipe. It is used in concrete and various structural power distribution projects. The commonly used nominal diameter is from -mm. The wall of wire sleeve is thin,Nibai16Mn seamless pipe manufacturer, which is mostly used after coating or galvanizing,I-beam is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.Difference and application description between H-beam and I-beamAfter the passivation treatment of alloy pipe, ~ 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.

I finally waited until I bought it NibaiHigh strength plastic alloy pipe. At first, I was still wondering whether to buy it. I liked it a little bit. I was a little scared to read the comments. I was afraid that the quality was not good. It was not a genuine product. It was a bit different from the picture. However, everything is wrong, the things are good, authentic, the boss is good, and the logistics are good.
