Import Tips
• Obtain API 5CT certification documentation to verify specifications and ensure compliance with drilling standards
• Provide mill test certificates confirming seamless construction, stainless steel grade, exact OD/wall thickness measurements
• Avoid misclassification as drill pipe by confirming primary use as protective borehole lining rather than rotation in drilling
