Provide a complete square section drawing before specifying hollow pipe for a service application.

Side dimensions and wall

The description identifies square tubing and a 0.4–16 mm wall range. No side dimensions are supplied, so specify both sides and a compatible actual wall rather than treating the range as a complete tube size.

Grade and route

The grade field says carbon steel with a general ASTM reference. Agree the exact designation, manufacturing route and inspection requirements instead of inferring a pressure or structural grade.

• Actual standard and designation
• Both square side dimensions
• Compatible wall thickness
• Length and end preparation
• Manufacturing and service inspection

Service acceptance

Several lengths from 6 to 12 m and fabrication services are described. Define intended operating conditions and tests separately; oil and gas wording and certificate names do not establish pressure capacity, weld quality or approval for a completed pipeline.
