corrosion resistant valves
5 in-depth engineering guides on corrosion resistant valves — specification, selection, testing and procurement.
Everything on corrosion resistant valves
Vajra's engineering team has published 5 technical guides covering corrosion resistant valves for industrial valve selection, specification, testing and procurement. Browse the full set below.
Valve Selection for Chlorine and Caustic Soda Service: Materials Guide
Chlorine (Cl2), hydrochloric acid (HCl), and caustic soda (NaOH) are among the most corrosive industrial chemicals - and among the most commonly misspecified for valve material. This guide covers the correct material selection, valve types, and design standards for chlor-alkali and chlorine-chemistry service.
Valves for Seawater and Offshore Service: Material Selection Guide
Seawater is one of the most corrosive natural fluids encountered in industry - high chloride concentration, dissolved oxygen, biofouling, and galvanic potential create an extremely aggressive environment that disqualifies carbon steel and standard 316 stainless from use without coating. This guide covers correct material selection, valve types, and standards for seawater and offshore service.
Valve Selection for Chlorine (Cl₂) Service - Materials, Safety & Standards
Chlorine is one of the most hazardous industrial chemicals. Valve material selection is counterintuitive - dry Cl₂ is less corrosive than wet Cl₂, and water is the most dangerous contaminant.
Duplex Stainless Steel Valves: Grade 2205 and 2507 for Corrosive and Offshore Service
Duplex and super-duplex stainless steels offer superior corrosion resistance to chloride pitting and stress corrosion cracking (SCC) compared to standard 316L SS - at roughly half the nickel content. This guide covers grades 2205 and 2507, PREN calculations, NACE compliance, and selection for offshore, subsea, and corrosive chemical applications.
How to Specify Industrial Valves for Chemical Service: A Complete Guide
Chemical plants handle some of the most aggressive fluids in any industry - strong acids, chlorinated solvents, caustic solutions, oxidising agents, and toxic gases. Specifying the wrong valve body material, seat, or seal material can lead to catastrophic corrosion, product contamination, or unsafe failure. This guide covers every variable in chemical valve specification.
