What Are H2S CORROSION-RESISTANT ESP SYSTEMS
H2S corrosion-resistant ESP systems protect against harmful H2S to reduce premature system failure and lost production. Corrosion-resistant ESPs reduce sulfide stress corrosion cracking, deliver long runlife, and offer reliable performance in highly corrosive wells.

Austenitic cast iron (Ni-Resist)
Sulfide stress corrosion cracking occurs when high levels of H2S and water cause hydrogen embrittlement in metal subjected to critical or prolonged tensile stress. One of the most common ways to combat the corrosive effects of sour well environments on production equipment is to manufacture components from austenitic cast iron. Commonly referred to as “Ni-Resist” iron, this material is a heavily alloyed type of cast iron containing graphite and non-ferrous alloy.
AISI 316L stainless steel
AISI 316L steel contains molybdenum to increase corrosion resistance in chloride containing environments and its low carbon content stands up to welding. Our H2S corrosion-resistant ESP systems use H2S corrosion-resistant materials in the housing, cable armor, fasteners, protectors, clamps, and other various ESP components as a barrier to corrosive fluids. We incorporate corrosion-resistant powder-coated stages in the pump that deliver exceptional runtime in sour wells. Like many of our other ESP systems, the corrosion-resistant ESP saves electricity over comparable systems and offers better gas handling capabilities.
