Our 316 Stainless Steel C-Series line Chemical and Corrosive Pumps satisfactorily handles many chemical and corrosive applications. However, sometimes a different type of stainless steel such as Duplex Steel is required. These include applications with fluids containing chlorides, hydroxides, or H2S. Such applications are frequently found in Oil & Gas processing.
For more details on these applications see “Corrosive Engineering” Additionally duplex is specified instead of 316 SS in applications which are both corrosive and abrasive because duplex is tougher and harder than 316 Stainless Steel.
LobePro stocks duplex steel parts for fast delivery of our D-Series duplex steel wet end pumps in a broad range of sizes. All LobePro Duplex parts are solution annealed and passivated. This is very important to obtaining the best resistance to chloride corrosion, pitting and cracking.
LobePro can provide pumps with wetends made in most types of super duplex, hastelloy, austenitic or martensitic stainless steels with approximately 4 months lead time. Applications requiring these special metals include those where Hydrogen Embrittlement, Caustic Chemical Corrosion, and Chemicals Oxidation are worries to name a few.
