High Frequency ERW Pipe Mill Production Line What is the ERW steel pipe? ERW tube or pipes are straight seams electric resistance welded pipe.in brief the ERW pipe,which is a round pipe welded by steel plates.It uses to transport vapor and liquid objects such as oil and natural gas.High-frequency welding on the quality of steel pipe1) Weld seam weld control of steel into the welded pipe unit by the forming roll,the guide roller orientation,the formation of a circular gap with a hollow tube,adjust the amount of kneading the kneading roll,making the weld gap control in 1 -3mm,and keep the two ends of the weld flush.Introduction to Welded Pipe Manufacturing - The ProcessJul 26,2018·The SSAW pipe diameter range is from 20 inch (406 mm) to 100 inch (2540 mm).The advantage part is we can get the different diameter of SSAW pipes with the same size of the steel strip,there is a wide application for the raw material steel strip,and welding seam should avoid the primary stress,good performances to bear the stress.
LSAW steel pipe,hot-rolled or cold-rolled steel sheet or steel coil made of steel pipe welding equipment in the straight seam welding are called the straight seam welded pipe.It is cut into strips by a steel strip,and then wrapped into a tubular cold mold.Then a special welder and then a seam welded.Outer weld brightly polished.LSAW Steel Pipe,DSAW Steel Pipe,Welded Steel PipeStraight seam welded steel pipe(lsaw steel pipe),Double-sided submerged arc welding steel pipe(dsaw steel pipe),longitudinal submerged arc welded steel pipe,high frequency straight seam welded pipe Grades For pipeline API 5L GR.B,X42,X45,X50,X60,X60,X65,X70,X80 For pilesProduction 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.

However,compared with the same length of the straight seam,the weld length to add 30 to 100%,and students have lower production rate.Therefore,most of the smaller diameter of the welded pipe to accept straight seam welding,large diameter welded pipe is mostly accepted spiral welding.Straight seam high frequency welded roll forming machineThe production process is simple but the production efficiency is high efficient.The Straight seam high frequency welded pipe roll forming machine can produce variety specification in sizes from 10 to 127mm,in shapes,it could be square,round,oval and uncommon shapes.The Difference Between High Frequency Welded Pipe and Dec 31,2020·1.High-frequency welded pipe High-frequency resistance welded steel pipe has a different welding process from ordinary welded pipe.The weld is formed by melting the base material of the steel strip body,and its mechanical strength is better than that of general welded pipe
Dec 15,2020·The Pipe Making Principle of ERW High Frequency Welded Steel Pipe.ERW straight seam steel pipe is made by using the skin effect of high-frequency current to quickly heat the edge of the formed tube to the welding temperature and then perform extrusion welding.According to different power feeding methods,ERW welded pipe can be divided into high frequency contact welding and high frequency induction welding.Two ways of welding high frequency straight seam welded Contact welding is a pair of steel electrodes in contact with both sides of the welded steel pipe,the induction current penetration is good,the two effects of high-frequency current are maximized by the direct contact between the steel electrode and the steel plate,so the welding efficiency of the contact welding Higher and lower power consumption,it is widely used in high-speed and low User rating 5/5Images of High Frequency straight seam Welded Steel Pipe imagesDifferenciating between straight seam and electric Dec 31,2020·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 pressure welding is performed under the action of the pressing roller to realize the production.
