Import Tips
• Document schedule/wall thickness precisely, as it affects pressure ratings but not HTS diameter classification
• Ensure end-finishing details (plain, beveled) match pipeline specs to avoid field preparation costs
• Comply with DOT PHMSA import requirements for pipeline safety standards
