Import Tips
• Hydrostatic test certificates required to prove pressure rating meets API 5CT P110 specifications
• Clearly mark 'OIL WELL CASING' on packaging and documentation to distinguish from line pipe
• Verify chrome/moly content in alloy analysis to confirm classification as alloy steel vs carbon steel
