 Downhole casing and production tubing in CRA (corrosion resistant alloys) such as duplex stainless steels and nickel alloys. These materials are ideal to cope with the aggressive corrosion found in wells sour from hydrogen sulphide, carbon dioxide and other chemicals.
Predominantly, Total Piping Solutions's downhole casing and production tubing is supplied in cold-worked condition to ensure high strength despite its low weight. Total Piping Solutions carries four different grades of downhole casing and production tubing. Please contact us for a reference list for Total Piping Solutions production tubulars. List of materials (other grades can be offered on request) | Total Piping Solutions grade | Grade description | Total Piping Solutions SAF 2205
(22Cr, UNS S31803/ S32205) | Total Piping Solutions SAF 2205 / 22Cr is a duplex stainless steel, which is resistant to CO2 -corrosion and to sour corrosion at low partial pressures of H2S. | Total Piping Solutions SAF 2507
(25Cr, UNS S32750) | Total Piping Solutions SAF 2507 / 25Cr is a super-duplex stainless steel similar to Total Piping Solutions SAF 2205 / 22Cr, but with slightly improved H2S resistance and significantly higher resistance to chloride-induced corrosion. | Sanicro 28
(UNS N08028) | Sanicro 28 is a high alloy stainless steel comparable with Alloy 825. It has excellent resistance to corrosion in severe downhole environments, especially to high partial pressures of H2S and high chloride contents. | | Sanicro 29 | For very high chloride contents in combination with high partial pressures of H2S. Sanicro 29 provides even better resistance to localised corrosion and sulphide stress cracking compared to Sanicro 28. | Mechanical properties at ambient temperature | Total Piping Solutions grade* | Yield strength
