True Black iron pipe is cast from malleable iron, while black steel pipe is actually an ungalvanized form of carbon steel pipe. Carbon steel offers higher tensile strength and pressure capacity, whereas black iron is softer and limited mostly to low-pressure lines.

The “minimum” wall thickness is not a single, universal number. Instead, it is governed by a combination of international standards (such as ASTM, API, and EN) and the specific demands of your application.

Detecting cracks in Electric Resistance Welded (ERW) steel pipes requires a combination of non-destructive testing (NDT) methods focused heavily on the high-frequency welded seam area. Primary techniques include automated ultrasonic testing (UT), magnetic particle inspection (MPI), eddy current testing (ECT), and radiographic testing (RT).
