Welded steel pipe (steel pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding. |
|
Produce an extensive selection of welded steel pipe including ERW, HFI, EFW, LSAW, DSAW and UOE type carbon steel pipe along with their respective flanges and fittings. |

Welded Tube and Pipe Manufacturing Processes |
|
Steel pipes are made by two different processes. The overall production method for both processes involves three steps. |
|
First, raw steel is converted into a more workable form. Next, the pipe is formed on a continuous or semicontinuous production line. Finally, the pipe is cut and modified to meet the customer’s needs. |
|
Ends of Pipes For the ends of pipes are 3 standard versions available. Plain Ends (PE) Threaded Ends (TE) Beveled Ends (BE) |
|
The PE pipes will generally be used for the smaller diameters pipe systems and in combination with Slip On flanges and Socket Weld fittings and flanges. |
|
The TE implementation speaks for itself, this performance will generally used for small diameters pipe systems, and the connections will be made with threaded flanges and threaded fittings. |
|
The BE implementation is applied to all diameters of buttweld flanges or buttweld fittings, and will be directly welded (with a small gap 3-4 mm) to each other or to the pipe. |
|
Ends are mostly be beveled to angle 30° (+ 5° / -0°) with a root face of 1.6 mm (± 0.8 mm). |
