ERW Pipe
Welded Pipe Is Formed By High-Frequency Resistance Welding Of Steel Coils.
The Weld Seam Material Is The Same As The Base Material, Which Ensures The Overall Performance Of The Welded Pipe.
The Maximum Diameter Of The Welded Pipe Is 24 Inches, And Its Main Material Is ASTM A53 And API Series Material.
Welded Pipe Is A Cost-Effective Product For Oil Transportation And Is Often Used In Conjunction With 3LPE Corrosion Protection.

ERW Pipe VS EFW Pipe
Balingsteel Can Produce High-Quality ERW and EFW Steel Pipes.
ERW Steel Pipe
Electric Resistance Welding Pipe
ERW Pipes Are Pressure Welded Without Filler Metal.
- The Weld Has No Other Components
- The Properties of the Weld Are Identical to the Base Metal
EFW Steel Pipe
Electric Fusion Welding Pipe
EFW Tubes Are Welded with Added Metal
- No Welding with Metal Filler
- Welding with Inert Gas Protection

Manufacturing Process of ERW Pipe
- Unwinding: Unwind the Steel Coil into the Strip.
- Slitting: Cutting the Strip Coil to Size to Ensure the Quality and Shape of the Strip.
- Loading Inspection: Check Whether the Steel Number or Grade and Specification of the Narrow Strip Steel Meet the Requirements of the Contract.
- Shear Butt Welding: Ensure That the Burrs of the Narrow Strip Steel Are in the Right Direction and That Proper Weld Openings Are Left When Butt Welding.
- Live Jacket Storage: Use the Pinch Roller or Storage Disk to Rotate and Roll the Strip into the Disk.
- Extrusion Molding: Adjust the Amount of W-Roll Under Pressure to Ensure the Quality of Molding and the Symmetry of the Weld.
- High-Frequency Welding: Use High-Frequency Welding Technology to Connect the Strips to Ensure the Stability of Weld Quality.
- Deburring: Remove Internal and External Burrs to Ensure Smooth and Clean Weld Seam.
- Cooling: Cooling Treatment for the Pipe Billet After Welding.
- Flaw Detection: Carry out Internal and External Non-destructive Flaw Detection to Ensure the Quality of Welding.
- Sizing and Straightening: Adjust the Size and Shape of the Billet to Make Sure It Meets the Standard.
- Final Inspection: Conduct Final Inspection on the Length, Appearance, and Performance of the Steel Pipe.
- Packing: Pack the Finished Products to Prevent Damage.
- Storage: Store the Qualified Steel Pipes for Sale or Further Processing.
Chemical Composition & Mechanical Properties
The Main Difference Between Welded Pipe and Seamless Pipe Is That the Molding Method Is Different, Welded Pipe Is Formed by Coil Welding, Seamless Pipe Is Formed by Perforating and Hot Rolling of Steel Rods, And There Is No Weld Seam in Seamless Pipe.
ERW Steel Pipe Is Used in Various Industries, Such as Housing Support, Scaffolding Construction, Fire-Fighting Pipelines, Liquid Pipelines, Oil and Gas Pipelines and so On.
The Meter Weight of ERW Is Calculated in the Same Way as for Seamless Tubes:[Outer Diameter – Wall Thickness] X Wall Thickness X 0.02466 = Weight per Meter (Kg). If You Need to Know the Detailed ERW Pipe Weight Chart, Please Contact Us.
