X52 X56 API 5L ASTM A53 DIN 2458 Welded ERW Black Pipe
DIN 2458 WELDED ERW Black Steel Pipe
ERW (Electric Resistance Welded), HFI (High Frequency Induction), HFW (High-Frequency Welding)
Steel is produced when carbon is added to iron, which is quite weak on its own. In modern industry, carbon is the most prominent additive to a ferrous material, but alloying elements of all sorts are common. In fact, alloying elements are common even in piping products still considered to be carbon steel.
Black pipes are formed from low – carbon mild steel on Automatic tube mill by high-frequency induction welding process. ERW pipes are welded longitudinally, manufactured from coil and can be manufactured up to 24” Diameter.
Black Steel Pipes have wide use across many industries due to its strength and ease of workability. Because it contains relatively few alloying elements and in low concentrations, black steel pipe is relatively economical.
