VM 95 SS-D

VM 95SSD.png

VM 95 SS-D is a high H2S grade 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 90% SMYS threshold level of resistance, no further check is needed. It is in accordance with API 5CT Grade T95 Type 1 PSL 2 with a K1SSC performance higher than those of API T95.

​APPLICATIONS

VM 95 SS-D can be used as tubing or casing with effluent containing H2S from room to high temperatures. VM 95 SS-D is available up to 16" and with heavy wall up to 1" and more. Recommended use is with pCO2 below 2psi / 0.14bar.

​PERFORMANCES

VM 95 SS-D is a 95 ksi grade H2S resistant guaranteed at 90% SMYS NACE A test and controlled for K1ssc in NACE A tes​t medium.​
