VM 110 SS-D

VM 110SS D.png

VM 110 SS-D is a high H2S corrosion resistant grade low alloy steel. It is specially designed for sour service resistance and is checked with NACE D (double cantilever test) quality control test. Its sour service resistance with uniaxial NACE A has been tested and verified at 85% SMYS threshold level of resistance, no further check is needed. It is in accordance with API 5CT Grade C110 PSL 1 with K1SSC performance higher than those of C110.

​APPLICATIONS​

VM 110 SS-D can be used as tubing or casing with effluent containing H2S from room to high temperatures. VM 110 SS-D is available up to 14" and with heavy wall up to 1" and more. Recommended use is with pCO2 below 2psi / 0.14bar.

​PERFORMANCES

VM 110 SS-D is an optimized 110ksi grade with restricted yield strength range grade H2S resistant guaranteed at 85% SMYS and controlled for K1ssc in NACE A test conditions.​
