Q:Where is the difference between seamless steel pipe and welded pipe
Seamless pipe pressure is higher, welded pipe is generally in 10 or so MPa, now welded pipe to do seamless processing.
Q:How much is 4 inches steel tube MM?
The nominal diameter of the 4 inch steel pipe is DN100, that is to say, the diameter of the center of the pipe wall is 100mm.
Q:What does the diameter of a steel pipe project mean?
Nominal surface meaning can be understood as a public address. It's as if everyone agreed to call something as a "devil", and he was the devil.Don't be confused by the numbers behind the nominal diameter. For example, DN50, this 50 is really close to the outer diameter or inside diameter of the steel tube, but DN50 is only a general model of the caliber of the national standard.
Q:What is DN50 for welded pipe?
Refers to the use of welded steel pipe made of DN50 steel pipe, refers to the inside diameter is 50mm, the market of common DN50 pipe also refers to the 2 inch pipe, standard pipe: 3.5mm thickness, pipe diameter 60mm, the weight of 4.88kg/m theory.
Q:What connections are there for concrete filled steel tubular column foundations?
Application of double beam connection node usually uses "I" shape columns and steel bracket which is around the construction technology of a modern steel concrete column girder casting formed in the steel pipe outside through the two structures, the bearing pin four axis and four angles on the common components of stress transfer. The construction technology in the application is usually used at both ends of the stress transfer construction mode, through the four steel bracket to the corresponding shear stress, avoid crack width because the node contact produces clear, delayed cracks, improve anti cracking ability of regional nodes.This node model in the connection when the longitudinal reinforcement without through the tube, without bending the construction can be carried out directly, with easy construction technology, construction control difficulty, the economic benefits of construction at the same time, the advantage of low reinforcement to save. In this joint engineering technology, the key pride is to control the stress transfer of steel bracket.
Q:Is the same specification seamless steel pipe more expensive than welded pipe?
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.
Q:What's wrong with the 3PP anticorrosive steel tube?
At present, mainly foreign related products come out, for some countries with relatively high ambient temperature, and PP than PE to hard, so as to avoid scratching coating.
Q:What does GALV mean in a steel tube?
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:What's the difference between round and round tubes?
Round steel is generally refers to steel, the surface is not threaded, different from round steel pipe, round tube is round tube.
Q:Are there specifications for scaffold steel pipe with 48mm * 3.2mm?
Previously used steel pipe GB 51*3.0mm, the latest national standard JGJ130-2001 stipulates that the use of steel pipe for construction projects need to be 48*3.5mm specifications, the wall thickness should be 3.5mm square for qualified products.
