VM 110 13CRSS

VM11013CRSS.png

VM 110 13CRSS is a super martensitic OCTG steel (also called Super 13%Cr steel) for sweet wet CO2 corrosive environments. It is manufactured in accordance with latest edition of API 5CRA and ISO 13680 – PSL 1. VM 110  13CRSS offers corrosion and SSC resistance on a greater usage domain than API L80-13CR in terms of temperature, H2S and chloride contents. VM 110 13CRSS is also available with High Collapse performance (VM 110 13CRSSHC).

​APPLICATIONS

  • Deep and/or HP/HT production tubing ​and liners exposed to flowing effluents contai​ning CO2
  • For temperatures up to ~180°C (356°F)
  • ​For limited amount of H2S

Finer grade selection shall take into account other parameters such as Chloride content and in-situ pH.​​


PERFORMANCES

OCTG carbon steels are known to corrode when exposed to wet CO2 containing environments: they will suffer from various forms of corrosion such as general metal loss corrosion or localized corrosion (pitting, crevice, Mesa attack). Marte​nsitic and Super martensitic steels have proved to be the most cost effective solution to protect against wet CO2 corrosion in oil & gas wells.
