Import Tips
• Verify seamless construction via mill test certificate; welded tubes classify under 7305/7306
• Provide material composition analysis to confirm 'other alloy steel' (e.g
• >1.65% Mn or specific alloying elements)
• Measure OD precisely (190.5-285.8 mm range) and wall thickness (<12.7 mm) to match statistical suffix
