Differences Between SAW and ERW Pipe Winsteel Group
ERW Welded Steel Pipe Manufacturing MethodWhen the ERW steel pipe welding process, two electrodes, usually made from copper, are used to apply pressure and current. The electrodes are disc-shaped and rotate as the material passes between them. This allows the electrodes to stay in constant contact with the material to make long continuous welds.

Difference between erw and saw steel pipe, Sunny Steel
As ERW steel pipe and SAW steel pipe in the pipe during forming, welding and process is different, so that two kinds of steel pipe in the performance there are some differences. (1) ERW steel pipe surface quality is superior to spiral submerged arc welded pipe, ERW steel pipe surface is smooth, smooth, beautiful, SAW steel pipe internal and external weld reinforcement.
The difference between ERW, SSAW, LSAW(UOE) Steel pipe
When the spiral submerged arc welded pipe (SSAW) is a coiled steel pipe, its advancing direction has a forming angle (adjustable) with the centerline of the forming pipe, and the edge is welded while forming. The welding seam is a spiral line.
Spiral Welded Steel Pipe, Sell Water Pipe, Youfa Gas Tube
The spiral welded steel pipe is manufactured using hot rolled steel strip which is spiraled at room temperature to be welded. Automatic submerged arc welding is the most commonly used method in the spiral tube production, and the end products come with welding seam both inside and outside.
Spiralweld pipe is manufactured from steel coil. The coil is unwound and then welded while it is being turned into the shape of the pipe. Changing the angle of the spiral and the thickness of the coil is all that is needed to change from one pipe size to another.
Welded Steel Pipes for Sales from leading Welded Steel
Welded steel pipe are common pipe type with technology and craft of welding. Normally welded steel pipe may divide into two categories such as electric resistance welded steel tube (ERW) and Spiral welded steel pipe. According to different welding methods, it can be divided into arc welded pipe, high frequency or low frequency electric resistance welded pipe, gas welded pipe, furnace welded
API 5L Spiral welded pipe for line pipe - steel pipe, ERW
Spiral welded pipe with spiral welded seam by double submerged arc welding to form the steel plates/coils into one pipe. Compare to API 5L ERW/LSAW/seamless pipes the advantage is the low products cost and high Material yield, with the large diameter and longer extent.
Electric Resistance Welded ERW Pipe ERW Pipes are manufactured by rolling the raw plate into a cylinder and then passing a current through to fuse the two ends. They are typically used for fencing, scaffolding and line pipes for fluid and gases.
Welded pipe can be divided into ERW, SSAW, LSAW, EFWERWElectric resistance welding pipe EFWElectric fusion welding pipe SSAWSpiral submerged arc welding pipe LSAWLongitudinal submerged arc welding pipe Among them, SSAW and LSAW are both called DSAWDouble side
ERW pipe is a type of Resistance pipe stands apart from welded pipe and DC welded pipe in two different manners as listed below. Based on the welding frequency, the IF welding for low frequency and the ultra-IF welding for high frequency.
In a spiral saw pipe, steel plate from the de-coiler is formed in a spiral loop. This spiral loop is then welded from inside and outside of the pipe. Because of the method of manufacture, a wide variety of diameters can be produced. Spiral saw pipes are used for low-pressure services.
Differences between ERW Steel Pipe and HFW Steel Pipe
The differences between ERW and HFW steel pipe, is EFW is a type of ERW process for ordinary and thin-wall thickness steel pipes. ERW pipeElectric Resistance Welded Pipe HFW pipeHigh Frequency Welding pipe. What is ERW steel pipe? ERW steel pipe is manufactured through low or high frequency resistances Electric Resistance.
