Agree a consistent round pipe specification before assessing the requested gas or oil application.

OD and wall ranges

The detailed OD range is broader than a separate 15–50 mm diameter description. The actual thickness option is 0.5–27 mm, compared with another 2–10 mm wall range, so confirm a compatible actual size.

Route and zinc layer

The title requests seamless pipe, but the detailed processing descriptions do not verify that route. The zinc layer is written as 0.8–4.0 mm; clarify its intended meaning and measurement basis without silently changing the unit.

• Actual grade and manufacturing route
• Compatible OD and wall
• Confirmed zinc layer specification
• Supply length and end details
• Service inspection acceptance

Service evidence

Six and twelve metre lengths are selectable. Define operating conditions and tests separately; application and fast delivery wording does not establish pressure rating, corrosion life or a delivery guarantee.
