  By Actual Weight

Hot-dip galvanized seamless steel pipe is identified for a selected tube-supply requirement.

Define the pipe geometry

State the actual steel grade, outside diameter, wall thickness and length. A general pipe name does not establish an inspected section or an available size range.

• Steel-pipe identity.
• Seamless route requirement.
• Hot-dip galvanized finish.
• Diameter and wall to specify.
• Length and tolerance to agree.

Provide the service brief

Include the component drawing, end condition and applicable acceptance criteria for the intended installation.

Request tube records

Obtain material, manufacturing, dimensional and coating inspection before use. Steel-coil descriptions do not define the finished pipe. No pressure rating, structural load, certified compliance or universal corrosion life is established without evidence for the selected tube configuration and actual service conditions.
