Mild steel and carbon-steel pipe requirements vary with service. Select the material standard and manufacturing route for the job, rather than ordering by the term MS alone. Confirm welded or seamless form, dimensions and end preparation.
Pipe selection
Specify the service, grade and compatible fittings together.
| Product / attribute | Common choices to specify | Buyer check |
|---|---|---|
| Welded or seamless | Choose by material standard and engineering requirement. | Request grade, NPS, wall/schedule, length and seam details. |
| Structural pipe | Dimensions, weldability and protection for fabrication. | Confirm coating, straightness and end finish. |
| Process pipe | Pressure/temperature design, material and inspection to project code. | Supply fluid, design code, pressure and test requirements. |
Dimensions and protection
ASME B36.10 describes dimensions of welded and seamless wrought steel pipe; it does not certify the material grade.
| Product / attribute | Common choices to specify | Buyer check |
|---|---|---|
| NPS and schedule | Nominal size and specified wall/schedule. | Check actual OD, wall tolerance and end prep. |
| Finish | Black, primed, galvanized or other coating if requested and available. | Confirm internal/external protection and compatibility. |
What to include in your enquiry
Send the grade and material standard, product form, thickness or NPS, complete dimensions, schedule/class where relevant, finish/coating, quantity, intended application, inspection/certificate needs, destination and delivery timing. Confirm current stock and the quoted material certificate before ordering.
Technical references
Catalogue reference: Carbon-steel pipes
Catalogue examples: ASTM A106 Grade B, API 5L X42–X70, IS 1239 and IS 3589. Seamless pipe range is 1/2–24 in; welded pipe range is 1/2–60 in; schedules 5–XXS. ASTM A179/SA210 Grade A1 boiler tubes and ASTM A333 Grade 6 low-temperature tubing are separate categories.
Ask for the actual material standard, grade, process route, size, schedule and testing requirements; the catalogue ranges do not establish today’s stock.
Metalex catalogue (2022) describes a product range, not real-time stock or a test certificate. Confirm grade, dimensions and documentation for your enquiry.
