Define actual service and certification requirements before selecting galvanized pipe for fluid or structural use.

Material and evidence

Q235B is the grade field while other carbon materials and several certificates are listed. Confirm actual material and applicable API, GB or SABS evidence rather than presenting the title's certified wording as a verified approval.

Geometry and coating

The actual wall option and detailed wall range differ, with separate outside diameter scopes. Select compatible OD, wall and 12 m length, then clarify the zinc layer field written in millimeters and confirm the actual hot dip and slightly oiled condition.

• Actual Q235B material
• Compatible outside diameter and wall
• Finished 12m length and tolerance
• Zinc layer measurement basis
• Service and certification evidence

Application acceptance

Oil, water, gas and construction are application labels. Request actual material and design tests; no pressure rating, potable water approval or structural capacity is established.
