Import Tips
• Include NACE MR0175 certification for sour gas service to confirm pipeline end-use and alloy suitability
• Document weld seam inspection (e.g
• ultrasonic testing) as proof of construction meeting 7305 line pipe standards
• Avoid bulk packaging that suggests casing use, which could shift to 7304 or 7306
