Q:How much is the tube?
The first prerequisite we need to determine is: what are the specifications of the steel pipe mentioned? Such as the commonly used steel pipe specifications: diameter 108*4.5, diameter 219*6, diameter 377*10, diameter and wall thickness of steel pipe with different specifications, different weight, so the steel price per meter is different.
Q:Seamed steel pipe seamless steel pipe, carbon steel pipe, galvanized pipe, four how to distinguish between
Major use differentiation:1, seamed tube can withstand the maximum operating pressure is generally less than 20 kg, which is the most secure use. It is generally used in water, gas, compressed air and other low-pressure fluid;2 seamless tube can withstand ultra-high pressure, of course, its wall thickness will also increase, which needs to be designed according to pressure requirements. It is generally used in high-pressure oil pipes, boiler tubes and other high temperature and high pressure equipment. There are also seamless tubes for structural purposes, depending on the design requirements.3, there are some seamed steel pipe seamless treatment tube, it is the weld annealing treatment, eliminate the residual stress of the weld, the weld and base material, the pressure range of basic and seamless pipe is. May also consider the use of.4, of course, the market also has some use overall heating after drawing steel pipe joints or mandrel rolling seamless steel pipe, mainly in small size, only in the shape of this kind of pipe belongs to the seamless tube, it is not very good
Q:What kind of argon arc welding wire is used for 16Mn steel pipe?
JB/T4709 recommends H10MnSi, but H10MnSi allows a lower value of strength of 430MPa, which does not match the parent material. I think American Standard is selected according to the selection of welding wire ER70S-6 GB ER50-6 wire can guarantee the equivalent strength of parent materials, and Si, Mn content can also guarantee the deoxidation effect, the weld joint is not easy to produce pores.
Q:Which is cheaper, angle iron or steel pipe?
Steel tube (Steel pipe) production technology development began in the bicycle manufacturing industry, the rise of the early nineteenth Century during the oil development, the two world war ships, boilers, aircraft manufacturing, manufacturing of power boiler after the Second World War, the development of chemical industry of petroleum and natural gas drilling and transportation, will effectively promote the the yield and quality of varieties, the development of steel tube industry.Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. Using steel pipe to manufacture road bridge can not only save steel, simplify construction, but also greatly reduce the area of coating protective layer, save investment and maintenance cost.
Q:20# seamless steel pipe and seamless steel pipe 20G what is the difference?
The difference is: 20# ordinary steel seamless steel pipe. 20G is the type of steel for high pressure boiler tubes.
Q:Hot galvanized steel pipe for use?
1, galvanized layer uniformity: steel pipe sample in copper sulfate solution immersion 5 times continuously, must not turn red (copper plated)2, surface quality: galvanized steel pipe surface should be complete galvanized layer, must not have plating on the black spots and bubbles exist, allow little rough surface and local zinc tumor exists.3, galvanized layer weight: according to the requirements of the buyer, galvanized steel pipe can be used for zinc layer weight determination, its average value should be not less than 500g/ square meters, and any sample shall not be less than 480g/ square meters.
Q:Seamless steel pipe 8162 and 8163 what is the difference?
GB 8162 is the structure of the tube, there is no need for flaw detection, the use of mechanical processing, stents;
Q:What does "1.5" steel tube mean?
This is neither an outer diameter nor an inner diameter; it should be related to an English unit at the beginning of the pipeline development; it is usually used to describe galvanized steel pipes; it corresponds to the English units as follows:4, in charge of: 4/8 inches: DN15;• 6 in charge: 6/8 inches: DN20;• 1 inch tube: 1 inches: DN25;• inch two tubes: 1 and 1/4 inches: DN32;• inch half tube: 1 and 1/2 inches: DN40;- inch tube: 2 inches: DN50;• three inch tube: 3 inches: DN80• four inch tube: 4 inches: DN100;
Q:What materials are used in scaffolding pipes?
Using 48.3 * 3.6mm steel pipe, the maximum thickness of the steel pipe shall not be less than 3.24mm (there should be no serious corrosion, bending, flattening or crack); the corrosion depth of the old steel pipe shall be in accordance with the construction fastener typeProvisions on the safety technical specification for steel pipe scaffold JGJ130-2011. Take three of the corroded steel tubes, and cut the samples at the most severe parts of the rust. The corrosion depth shall not exceed the prescribed valueUse。 In addition, the approach of the steel pipe should also be sampling retest, qualified before use.
Q:DN150 welded steel tubes one meter multiple
DN150 welded steel pipe according to the thickness of two specifications: outer diameter 165mm, wall thickness 4.5mm, 17.81Kg per meter weight, wall thickness of 5.5mm, 21.63Kg. per meter weight
