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
