Materials descote has an extensive know-how in working with a wide range of materials, from low temperature carbon steels to special alloys, to match specific process conditions. Materials are selected according to the actual service conditions (fluid, temperature, pressure, etc.) and environmental circumstances (tropical location) to ensure optimal life of the valve. We are used to facing the complexity of working with highly corrosive environments, tensile stress and thermal variations. Microstructure low temperature alloy Microstructure of steel alloy Microstructure of duplex SS Welding is performed by ASME IX, EN 287-1, HP-0 qualified welders.

Halogens' Characteristics Liquid or gas Chlorine (Cl2), Fluorine (F2), Hydrogen Chloride (A-HCl), Phosgene (COCl2), hydrofluoric acid (A-HF), and chloro-fluorinated compounds all display similar hazards: - Lethal: Emissions are not tolerated - ZERO leakage allowed. - Corrosive: Presence of scale and deposits challenges reliability and performance of equipment. - Liquefied Gas under pressure: Changes from liquid to gas state induces flashing, cavitation and thermal shocks in the valve. - Hygroscopic: Media highly reactive with moisture and humidity triggers the spread of corrosion. - Other critical and hazardous applications: Pyrophoric / Explosive / Noxious / Erosive / Abrasive / High Pressure descote specializes in developping high integrity products for hazardous and critical applications only. << Core business Requirements >> Home Company Applications Product scope Inquiry Contact us Applications Characteristics Requirements Quicklinks HF Alkylation & LAB process News © 2013 descote s.a.s. - All rights reserved - Terms & Conditions
