  Package

  Seaworthy Standard Package

Seamless stainless steel round pipe is described with custom-length requirements. The single actual Thickness option is a combined list, not separate stock variants for every wall size.

Define the tube geometry

The option lists 0.5,0.6,0.8,1.0,1.2,1.5 and2.0mm, etc. Family wall thickness0.5–50mm and OD6–2500mm require an actual OD/wall pairing.

• Round section.
• Seamless construction reference.
• 304/316L alloy choices.
• Multiple surface finishes described.
• Cutting and moulding services listed.

Verify mechanical requirements

Reference tensile strength is515–750MPa, yield205–450MPa and hardness≤HRB95. Confirm alloy, condition and test scope rather than applying all values universally.

Specify service acceptance

Chemical-processing and water-treatment contexts do not establish pressure or corrosion limits. Agree length, surface and applicable JIS/schedule criteria with actual material and dimensional records.
