VM 80 S

VM 80 S.png 

VM 80 S is a H2S corrosion resistant grade low alloy steel. Its sour service resistance has been tested and verified. No further check is needed that allows shorter lead time. It is manufactured in accordance with API 5CT grade L80 type 1 PSL 2 and NACE MR0175 but have a better threshold level of resistance to sour environment.​

​APPLICATIONS

VM 80 S can be used as tubing or casing with effluent containing H2S from room to high temperatures. Recommended use is with pCO2 below 2psi / 0.14bar.​

PERFORMANCES

VM 80 S is a 80 ksi grade guaranteed ​H2S resistant at 85% SMYS in NACE A test conditions​.​​
