API 5L Pipe in Seamless Type inlcuding Hot Rolled Seamless and Cold Rold Seamless. Outer Diameter for this type normally under 24 inch. Welded Type inlcuding:ERW:Electric Resistance Welded, for manufacturing pipes OD under 24 inch. SAW/DSAW:Submerged Arc Welded (Double Submerged Arc Weldedd), for manufcturing pipes OD up to 100 inch.
Difference between helical welded pipes and longitudinal Welded pipes seams withstand two stresses, the radial stress Y and axial stress X. The compound stress can be derived from the formula =Y(l/4sin2+cos2)1/2 , refers to the helical angle. Normally, the angle for helical welded pipe is 50° to 70° while for longitudinal pipe is of course 90°, so it can be concluded that the
The biggest difference between seamless elbows and welded elbows are whether there is a weld, but now many of the welded steel pipes will be polished off the welding seam before they leave the factory.The elbow that is made out of this steel pipe is invisible to the welding seam.There are a lot of exporter sell this kind of fake seamless elbow
Differences between ERW Steel Pipe and HFW Steel PipeHigh frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHZ. Through high-frequency current welding resistance, the heat generated in the contact objects, so the objected surface are heated to the plastic state, then with or without forging to achieve a combination of steels.
Electric Welded (ERW) Round Steel Tube Coremark MetalsElectric resistance welded (ERW) round steel tubing is an excellent candidate for most processing. Steel round tubing is available in A500 grade B, A513, and A135 depending on outside dimensions. ERW steel round tubes have a non-coated, semi-smooth dark grey finish, and a welded seam along the inside.

How to grind, blend and finish a weld seam Norton Mar 19, 2019 · The weld seam is neater, smaller and the most common weld use on stainless steel. The difference between finishing Carbon Steel and Stainless Steel The decision over what kind of finish you are looking to achieve is linked strongly to the application of the finished piece and the base material itself.
Metal Pipe - Seamless Pipe - ERW Pipe - Galvanized Pipe Types of Pipes and Tubular Goods There are six types of pipes and tubular goods. Standard Pipe:There are three different types of standard metal pipes - welded (ERW Pipe), seamless pipe, and galvanized pipe. They represent 10% of all tubular products. Line Pipe:Used primarily in Oil and Gas Applications. Line pipe includes ERW, FW, SAW and DSAW Pipe.
The first is longitudinal welding, which welds the long seam of the pipe on both the inside and the outside. The final welding step is circumferential welding. Using the submerged arc welded (SAW) process, we fit the cans together to create the specific length you request for your pipe.

Welded steel pipe distributor in China for international The carbon steel pipe that forms to round or square shape by bending steel strips and plates and through welding process, is called welded steel pipes according to its definition. So simply understanding about welded pipes is the pipe with welding process, and you may find welding seam on the surface of welded steel pipes.
B. Longitudinal Seam welding. The advantage of using a seam welder is that it easily enables the joining of two flat plates of a tubular pipe without any tack welding. Longitudinal seamers provide an automated welding process carried out on smooth plates, sheets, pipes and tank sections to make cylindrical work pieces.Spiral Welded Pipe Manufacturing ProcessSpiral welded pipe (SSAW/SAWH):a low carbon carbon structural steel or low alloy structural steel strip is rolled into a tube blank at a certain spiral angle (forming angle), and then the tube seam is welded together. It can be made with a narrower strip Steel produces large diameter steel pipes. Its specifications are eed by outer diameter * wall thickness, and the welded pipe
