high frequency straight seam welded pipe steels
Cut about 100mm welded pipe and place it on a conical top core; place the conical top core under the hydraulic press,start the oil pressure,slowly press the welded pipe down,and when the flaring is 8%,check whether the weld is cracked.If there is no crack,weld the seam; if there is crack,adjust the welding process parameters in time.3.Comparison of Straight Seam Steel Pipe and Spiral Steel PipeThe production process of straight seam steel pipes is relatively simple,and the main content of the production process is high-frequency welded straight seam steel pipes and submerged arc welded straight seam steel pipes .The production efficiency of straight seam steel pipes is high,the cost is low,and the economy develops rapidly.Differenciating between straight seam and electric High-frequency welded pipes are generally straight-slit,but straight-slit welded steel pipes are not necessarily high-frequency welded.The high-frequency straight-slit electric resistance welded steel pipe is formed by the skin effect and the proximity effect of the high-frequency current after the hot-rolled coil plate is formed by the molding machine,and the edge of the tube blank is heated and melted,and
High frequency straight seam welded pipe is a legally registered limited company specializing in the production and sale of metallurgical equipment and high-frequency welded pipe equipment,It is a professional manufacturer of pipe mill and cold roll forming machine Images of High Frequency Straight Seam Welded Pipe Steels
imagesWhich Industries are Straight Seam Steel Pipes Widely Used in?Sep 22,2020·Straight seam high-frequency welded pipe is a welded pipe that is continuously produced on the production line using steel strip (coil) as the raw material and high-frequency welding technology.The material strength is generally below 450MPa,andLSAW Steel Pipe,DSAW Steel Pipe,Welded Steel Pipelongitudinal submerged arc welded steel pipe,high frequency straight seam welded pipe.Grades of LSAW Steel Pipe For pipeline API 5L GR.B,X42,X45,X50,X60,X60,X65,X70,X80.For piles ASTM A252.Sizes of LSAW Steel Pipe OD 16-72.

The high frequency straight seam steel pipe (eg:ERW steel pipe) is based on the principle of electromagnetic induction and the skin effect,proximity effect and eddy current heating effect of the AC charge in the conductor,so that the steel at the edge of the weld is locally heated to a molten state,and the butt weld is realized by the extrusion of the roller Intercrystalline bonding,so as to achieve the purpose of welding seam welding.Production Standard of High Frequency Straight SeamThe high-frequency straight seam welded pipe is generally produced with a small diameter,and the outer diameter is generally less than 660mm or 26 inches.Its characteristics are fast welding speed,for example,for steel pipes with an outer diameter of less than 1 inch,the maximum welding speed can reach 200 meters / minute.
