Q:What is the difference between hot dip galvanized steel pipe and galvanized steel pipe?
1, the process is different, one is chemical treatment, one is physical treatment; hot-dip galvanized coating is reliable, not easy to fall off2, hot-dip galvanized coating thickness, so strong corrosion resistance. And zinc plating (electroplating) coating evenly, surface quality is better, coating thickness is generally between a few microns to more than ten microns.3 hot galvanizing is a chemical process, which belongs to electrochemical reaction. Zinc plating is a physical treatment, just brush a layer of zinc on the surface, there is no galvanizing inside, so the zinc layer is easy to fall off. Hot-dip galvanizing is used in building construction.4 、 hot galvanized pipe is to make molten metal and iron matrix reaction and produce alloy layer, so that the substrate and coating two combination.
Q:Will the steel tube dance?
In a single pole dance performance, the dancer moves more naturally, herself, moves and techniques, and does what she wants to do, while the style of dance is determined by herself, no one intervenes, and quite free.
Q:How can the immersed pipe pile put steel cage into the steel pipe? Which expert to answer?
The pile reinforcement cage construction characteristics: in general application of the reinforcement cage can be used when not required manual assembling reinforcement cage, such as deep or large pile diameter should be used for solid and solid mechanism of reinforcement cage better (by reinforcing cage seam welder production) to meet Zhuang Jishi high technology requirements, enhance the stability of pile foundation.
Q:How can galvanized steel tubes be painted on the surface?
Suitable for galvanized base material (antirust primer), epoxy zinc yellow primer (double component), epoxy ester zinc yellow primer.Pretreatment of galvanized sheet when brushing:1, conditional, you can zinc plating phosphating treatment, or first spray a layer of phosphating primer.2, or smooth zinc plating surface sweeping treatment.3, the galvanized workpiece, galvanized pipe surface with solvent (that is, epoxy zinc yellow primer, thinner) wipe, in order to remove the workpiece crude oil protective layer, and increase cleanliness.4, two-component epoxy zinc yellow primer: in strict accordance with the proportion of paint and curing agent paint, and aging 30 minutes later, modulation suitable construction viscosity, you can spray.One component epoxy ester primer: zinc yellow construction viscosity suitable to construction of modulation, the correct construction method.
Q:How to perform nondestructive inspection of steel tubes
The detection principle is based on the ferromagnetic material is magnetized in a magnetic field, discontinuity materials and products (defects) produce leakage magnetic field, magnetic powder adsorption (or detecting) and appear (or on the instrument display). Therefore, this method can only be used for the inspection of the surface or near surface defects of ferromagnetic materials or products.
Q:Which is more load-bearing, the same thickness of steel pipe and steel bar?
The same length, the same pipe diameter, the same material strength is hollow, the ratio of area of steel (solid), and the cyclical and slender radius smaller than the larger, so the longitudinal stability coefficient is smaller, three factors, two factors are weak in steel reinforced, another factor: strength, they are the same, no doubt, steel reinforced bearing less than.
Q:What's the difference between the fastener type steel pipe scaffold, the floor type steel pipe scaffold and the overhanging type steel pipe scaffold?
Classification is not the only way, fastener type steel pipe scaffolding is divided by force, and the latter 2 are classified according to the structure.
Q:What are the main types of steel pipe ah? How to judge which kind of steel pipe performance is better?
Welded steel pipe for different welding process and divided into the furnace pipe welding (ERW) pipe and automatic arc welding, because of the different forms of welding seam welded pipe and spiral welded pipe is divided into two kinds, end its shape is divided into circular welded and shaped (square, flat) pipe.The welded pipe is rolled into the steel tubular to sew or spiral seam welded in the manufacturing method, and is divided into low pressure fluid delivery with welded steel pipe, spiral welded steel pipe, welded steel pipe, welded pipe roll etc.. Seamless steel pipe can be used in various industries, such as liquid, pneumatic, pipeline and gas pipeline. Welding pipes can be used in water pipelines, gas pipelines, heating pipes, electrical appliances, pipelines and so on.Press materialSteel pipe according to the pipe material (ie steel) can be divided into: carbon tube and alloy tube, stainless steel tube.Carbon tube can be divided into ordinary carbon steel tube and high quality carbon structure tube.The alloy tube can be divided into: low alloy pipe, alloy pipe structure, high alloy tube, high strength tube. Bearing tube, heat resistant acid resistant stainless pipe, precision alloy (such as cutting alloy) pipe, high temperature alloy tube, etc..
Q:Seamless steel tube DN15 specification phi 18*3 what do you mean?
Seamless steel pipe having a hollow cross section, used as a conduit for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials. Compared with solid steel such as round steel, steel tube is lighter in strength and equal in resistance to bending and torsion. It is an economical cross section steel and is widely used in the manufacture of structural and mechanical parts.
Q:20# seamless steel pipe and seamless steel pipe 20G what is the difference?
20G seamless steel tube is a high-pressure boiler tube. In addition to carbon content, 20G seamless steel tubes also have some trace elements that are more suitable for use as boiler pressure vessels. In addition, 20G also focuses on its physical performance. Such as bending, impact and tensile properties. 0G seamless steel tube is a kind of steel strip with hollow section and without seams. A steel pipe having a hollow cross section, used as a conduit for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials.
After more than a decade’s construction and development, we have taken a leading position in seamless steel tube industry in China. In the year 2007, it awarded Famous-brand product Certificate. Besides, we have been named as excellent supplier of Qualified Products by our customers for several times.
