Special Grades & Premium Connections
The VA-Series of products are designed for special applications. They may or may not be addressed by the API-Specifications. When the service application is addressed by an API grade, the VA-Series will exceed the API requirements. The practices available to achieve the stated goals include but are not limited to:
• Steel with a special chemical composition
• Special steel-making practices
• Use of SPC during rolling and heat treatment
• Reduced tolerances
• Mechanical properties restricted to a more stringent range
• Additional testing
Depending on the final use, appropriate processes are taken.
