ERW (Electric Resistance Welded), HFI (High Frequency Induction), HFW (High-Frequency Welding)

The oil and petroleum industries use black steel pipe for moving large quantities of oil through remote areas. Black steel pipe’s strength makes it ideal for transferring water and gas in rural and urban areas and for conduits that protect electrical wiring and for delivering high-pressure steam and air. Additional uses for black steel pipes include gas supply inside and outside homes, water wells high-frequency and sewage systems. This is advantageous since black steel pipe needs very little maintenance. Black steel pipes are never used for transferring drinking water.

ERW steel pipes and tubes are available in various merits, wall thicknesses, finished and diameter, which are majorly used in various industrial purposes, fencing, scaffolding, etc.

The biggest difference between ERW pipe and seamless steel pipe is that ERW pipe has welding line, which is the same as welded steel pipe, but seamless black steel pipe doesn’t have, either does the welded steel pipe. Furthermore, the welding line of ERW pipe is the key to the quality of ERW steel pipe. The more unrecognizable the welding line of ERW pipe is, the higher quality ERW pipe has.
