Steel designation

The title requests S275JR and an ASTM reference, while the detailed grade is Q235B with other carbon steel materials listed. Agree the exact standard and designation and obtain evidence rather than assuming grade equivalence.

Diameter and wall

The OD description spans 3–700 mm, while the actual thickness option is 0.5–27 mm with 6 or 12 m lengths. Confirm the requested 15, 20 or 25 mm diameter and a physically compatible wall.

Service acceptance

Fluid and structural uses are described. State the intended service conditions and coating criteria; general certificate names and middle pressure wording do not establish a pressure rating, certified standard compliance or suitability for a complete pipeline.
