1Structure of Seamless steel tubes for the United States and the United Kingdom standards

 Seamless steel pipe has a hollow section, a large number of pipes used for conveying fluid, such as oil, natural gas, gas, water and some solid materials, etc Seamless pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable.

Q:What type of steel pipe dance is used in general?
According to international competition practice, the standard size of steel tube is 40 mm or 45 mm in diameter, and the 45mm is usually used. The height of the steel pipe is not less than 3.3 meters and not higher than 4 meters.
Q:Outside diameter 60, thickness 3.5 seamless steel tube, how many kilograms per meter?
Steel tube Kg/m (including seamless steel tubes and welded tubes) theoretical formula per meter weight: W=0.02466 * S * (D-S)Of which: S - wall thickness (mm), D - steel tube diameter (mm), W - kg / M
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:Heating system DN40 and DN32 welded steel pipe how to connect?
Welding: AC arc welding machine welding. Mode 1: apply to the medium of non demanding piping, DN40 steel pipe necking and DN32 steel pipe butt welding, or directly DN32 steel pipe into the DN40 internal welding. 2: the pipeline requirements apply to the inner wall of smooth transition, reducing short circuit welding for DN40x32 suppression of this mechanism are used for connection pipe seamless steel pipe high pressure pipeline connection, no special requirements, not commonly used welded steel pipe. Connection of mechanism fittings is not only costly, but not necessary unless special requirements are required!
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?
Carbon steel is relatively alloy steel. Its carbon content is higher than alloy steel, and 20# steel is one kind of carbon steel.
Q:What's the difference between straight steel pipe and seamless steel pipe?
Seamless steel pipe and welded pipe are separated because of different production process. Seamless steel tubes include hot rolling, cold rolling, cold drawing, and other rare, such as cold extrusion.
Q:Stainless steel tube, also known as why tube?
Use can be divided into oil well pipe (casing, tubing and drill pipe etc.), line pipe, boiler tube, mechanical structure, hydraulic prop pipe pipe, cylinder pipe, geological pipe, chemical pipe (high pressure fertilizer pipe, oil cracking tube) and shipbuilding pipe etc.
Q:How to perform nondestructive inspection of steel tubes
Radiographic inspection (RT)One of the earliest nondestructive testing methods is widely used in the inspection of internal defects of metals and non-metallic materials and products, with a history of at least 50 years. It has incomparable unique advantages, that is to test the correctness, reliability and intuition of the defects, and the ray film can be used for the analysis of defects and as a quality certificate archive. But this method also has the disadvantages of more complicated equipment and higher cost, and should pay attention to the protection of radiation.
Q:The outer circle of a seamless steel pipe 50 head into the outer circle of the 40 to close
Cold drawn steel tube and cold rolled steel pipe mill is a complete set of equipment which combines cold rolling, cold drawing, cold rolling and cold drawing to produce pipes. It is a unit for deep processing of hot-rolled pipes or welded pipes.
Q:Steel pipe is particularly long, how to clean the inner wall of the pipe so that it can be thoroughly cleaned
If the pipe is relatively long, you have water, you can buy ultrasonic vibration plate into the water for ultrasonic cleaning, if not too long with an ultrasonic vibration rod, inserted into the pipe cleaning, and then rinse with water by ultrasonic stripping of dirt, give you recommend a factory in Jining Hengda
