VM 80 IRP

VM 80 IRP.png​​ 

VM 80 IRP is a high H2S corrosion resistant grade low alloy steel. Based on API 5CT L80 Type 1 PSL 2 with restrictions on aimed chemistry, it is specially designed to respond to IRP standard requirements. The sour service resistance is checked with NACE A (uniaxial) and NACE D (double cantilever test) quality control test.

​APPLICATIONS

VM 80 IRP can be used as tubing or c​asing with effluent containing H2S from room to high temperatures. VM 80 IRP 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 ​80 IRP is a combination of best practice and high level of quality control.
