Define both square side dimensions before selecting this hollow tube for a service requirement.

Section and wall

The description gives square shape and a0.4–16 mm wall scope without actual side dimensions. Provide a complete section drawing and a physically compatible wall rather than treating that range as a finished tube size.

Grade and manufacture

The material field says carbon steel with a general ASTM reference. Agree an actual designation and manufacturing route with material and weld inspection rather than inferring a pressure or structural grade.

• Actual standard and designation
• Both side dimensions
• Compatible wall thickness
• Supply length and cut ends
• Manufacturing and service tests

Acceptance requirements

Several lengths and fabrication services are described. Define actual operating and forming needs separately; oil and certificate wording does not establish pressure capacity, weld quality, structural load or approval of a finished pipeline.
