Import Tips
• Provide detailed grade certificates (e.g
• K-55 PSL-1) and hydrostatic test reports to demonstrate fitness for oil/gas use
• Measure wall thickness precisely post-manufacture, as variations can trigger reclassification
• Avoid delays by pre-submitting isometry drawings showing seamless structure and thread type
