V & M Riser grades 

Choose the right grade for your application

Reference projects chose API and V & M proprietary grades in high strength from 80 ksi up to 125 ksi, also in HC and SS.

Why V & M Riser grades ?

We offer V & M Riser grades to meet the known needs of our customers.

Requirements are individually defined in their specifications and derived from lessons learnt. The summary of these different needs is the basic idea behind launching the V & M Riser grades series.
In addition we want to contribute to the ongoing process of the Offshore Industry to establish new standards.
Seamless High strength grades are selected in all three Riser applications:

Production outer / inner / tubing riser
SBOP Drilling riser
Workover - early production riser
