Pipeline Pickling & Passivation Services Services in India

About Our Pipeline Pickling & Passivation Services Service

Welding of stainless steel piping creates heat tint and weld oxide that compromises corrosion resistance. Carbon steel piping develops mill scale and rust. Ram Engineering performs acid pickling to remove these oxides, followed by passivation to form a durable chromium oxide layer, restoring full corrosion resistance.
