Q:Welded and seamless steel pipe how to distinguish?
Different processing technology:Seamless tubes are made of quality carbon steel or alloy steel. Processing technology of seamless pipe hot rolling and cold drawing is divided into two ways, and the tube is generally based on welded.
Q:Fastener type steel pipe scaffold steel pipe wall thickness
According to the "construction of fastener type steel pipe scaffold safety technical specifications JGJ130-2011" stipulates that the specification of steel pipe should be Phi 48.3 * 3.6, that is, wall thickness is 3.6mm. The standards in Shanghai are in line with national standards and 3.25mm can be used.Shelf tubes commonly used specifications, sizes are generally 48.3x3.0, 48.3x3.25, 48.3x3.5.
Q:Difference between seamless steel pipe and welded pipe
Seamless steel tubes are made of high quality carbon or alloy steel. They are hot-rolled and cold-rolled (drawn).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..
Q:Is there any difference between thermal expansion seamless steel pipe and seamless steel pipe?
Differ,Thermal expansion seamless steel tube is what we often call "thermal expansion tube", the density is relatively low, but a strong contraction of the steel pipe, (seamless steel pipe) can be referred to as "heat expansion.". A finishing rolling process for pipe rolling by using oblique rolling or drawing method to enlarge pipe diameter. In a relatively short period of time, the outer diameter of the steel pipe becomes larger, and the seamless tube with nonstandard and special type can be produced, and the cost is lower and the production efficiency is high, which is the development trend of the international rolling tube field at present.
Q:What connections are there for concrete filled steel tubular column foundations?
In the connection work, strengthening ring joint stiffness, high bearing capacity and no parts through the tube, it is especially suitable for the small diameter steel tube concrete column structure, complex engineering projects, especially those in the pump sending pouring construction method, which is more important, it has a basic guarantee strictly for the quality of concrete construction. When concrete columns with larger diameter, ring type joint construction steel is large strengthened, so as to make the project construction become more complex, and the connection between the longitudinal rebars becomes cumbersome.
Q:Why should the weak electricity be pre buried with galvanized steel pipe?
Galvanized steel is widely used in construction, machinery, coal, chemical industry, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries.
Q:Is hot dipped plastic pipe steel?
The characteristics of hot dipped plastic pipe are:1., hot dipped plastic pipe superior anti-static performance: through the formula to add antistatic agent, so that its internal and external surface resistance value reached and exceeded the national industry standards.2., such as the use of plastic raw materials, add flame retardants. The flame retardant performance index conforms to the national standard, and the steel plastic composite structure has better flame retardance than the pure plastic pipe material, and is suitable for underground inflammable, explosive and other places.3. hot dip coating steel strong adhesion: steel surface after special treatment, curing, coating adhesion is greater than or equal to 30N/10mm.4., dense internal and external resin layer: coating thickness of more than 0.5 mm, no pinholes, with excellent corrosion resistance.The mechanical properties of plastic steel pipe superior 5. hot dip: can withstand the harsh conditions of use: coating steel has good toughness, high mechanical strength, impact bending and other foreign influence, has a strong bearing capacity, has better performance than other mine plastic pipes.6. hot dip steel corrosion and fouling, the fluid resistance is small: corrosion and fouling, especially suitable for the underground conveying high sulfur water and transport of calcium and magnesium plasma water, save the maintenance cost, service life is much higher than that of the other pipe, high economic benefit.7. self lubrication: smooth wall, no fouling, small transmission resistance, under the same conditions, can improve the transport capacity of 30%.8. convenient and reliable connectionThe utility model completely overcomes the defects of the difficult connection of the pure plastic mining materials, and can be connected with the underground steel pipe and the valve by using flanges, fast couplings, etc., and has strong interchangeability.
Q:What's the material of Q325 steel pipe?
Q235 refers to the material yield stress of 235MPa carbon steel, because of its low price, good machining and welding performance, it is generally used for welding structural parts. Of course, the unimportant parts can be used for it.
Q:Is it good to buy a simple wardrobe or a steel pipe?
If the home place is big, buy Wooden, good-looking durable, if the place is small, buy cloth, easy to receive, mobile, tidy and cheap.
Q:Who knows what is the difference between double submerged arc welded pipe and longitudinal submerged arc welding?
The straight seam welding is relative to the spiral welding and the T-shaped welding, and so on.
