Q:What does "SC50" steel pipe mean in civil engineering?
In the production of T-shape welded steel pipe, the wrong edges happen frequently, and the influence factors are many. In production practice, steel pipe degradation is often caused by dry, wrong and side errors. Therefore, it is necessary to analyze the causes and preventive measures of spiral steel tubes.
Q:What is the difference between the stainless steel pipe welded pipe and seamless pipe?
Grain size: usually, the grain size of the metal is related to the heat treatment temperature and the time at which the metal is kept at the same temperature. Therefore, the welded pipe and seamless tube annealing of the same grain size. If the minimum tube cold treatment, the grain size of the weld metal is smaller than the grain size, welding or grain size is the same.Strength: the strength of the pipeline in the composition of the alloy and alloy containing the same and the same heat treatment of seamless tube and seamed tube essentially consistent strength. After the tensile test and three-dimensional vibration test, tube tearing almost all occurred in the welding point or away from the heated area where. This is because there is little impurity in the weld and the nitrogen content is slightly higher, so the strength of the welded joint is better than that of other parts. However, the ASME Boiler and Pressure Vessel Association believes that the seamed tube can withstand 85% of the allowable pressure, which is mainly due to improved welding equipment data collection prior to today. The provisions of ASME 100% completely under license by ultrasonic testing pressure tube. Similarly, Europe and Asia also stipulates that can ensure the quality of welding performance by eddy current test tube, the eddy current testing is subject to legal procedures and licensed institutions. Trent's eddy current test was approved by the Swedish power division. ASME believes the current loss is relatively small, high-quality performance based on the seamed tube.
Q:What is the weight of hot galvanized steel tubes? DN150 4mm wall thickness
GB/T3091-2008: DN150 welded steel pipe, wall thickness of 6mm, the theory of the weight of welded steel pipe 24.02kg/m, galvanized steel pipe should be multiplied by the weight coefficient after galvanizing, C, DN150, wall thickness of 6mm, C=1.02, DN150, theoretical weight and wall thickness of 6mm galvanized steel 1.02*24.02= 24.5kg/m.
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 does carbon seamless steel pipe mean? What is the difference between a seamless 20# and an ordinary one? What is it used in detail?
In general, steel is divided into two groups according to their chemical composition: carbon steel and alloy steel;(1): carbon steel low carbon steel (C = 0.25%); carbon steel (0.25% < C < 0.60%); high carbon steel (C = 0.60%)(2): alloy steel, low alloy steel (alloy is less than or equal to 5%); in steel (5% < < 10% alloy; high alloy steel (alloy) = 10%)Carbon seamless steel tubes are mostly pipes for mechanical engineering structures and pipes for conveying fluids.
Q:Does seamless steel tube have a bend of 135 degrees?
In engineering, it is usually marked as "45 elbow" and has no "135" mark. The angle of the elbow is acute, so there will be no more than 90 degrees elbow.
Q:How to calculate the maximum bending stress of steel pipe? Is there a list of the maximum flexural normal stresses for steel pipes of different materials and diameters?
Strength design of steel pipe by this formula to calculate the maximum normal stress in the steel pipe should be less than the value (based on your choice of different grades of steel, steel strength design value is not the same, this value can also be found through the design manual of steel structure), meet the requirements, it can meet the requirements of steel pipe under the action of bending moment strength.
Q:How to make the magnetic steel, can be like a magnet?
Of course, not all materials can be magnetized, austenitic stainless steel will not do.
Q:DN150 welded steel tubes one meter multiple
Calculated theoretical weight (Kg) per inch of welded steel pipe = (outside diameter wall thickness) * wall thickness * 0.02466DN150 welded pipe, "150" means nominal diameter of 150mm. Its outer diameter is 165mm.
Q:Are there specifications for scaffold steel pipe with 48mm * 3.2mm?
However, there are a variety of non GB steel tubes on the market, mainly in the wall thickness, and are thinner than the national standard requirements, you said that thickness may have, but the thinnest only about 2.6mm-2.7mm.
