| Field | Order reference |
|---|---|
| Standard | Applicable equipment specification, such as A249 for welded austenitic tubing |
| Product or route | Straight tubes with expansion or welded tube-sheet joints as specified |
| Critical dimensions and fit | Provide actual OD, wall basis, tube length and tube-sheet drawing |
| Supply enquiry | Confirm sizes, lengths, route, documentation and lead time for your order |
Illustrative drawing sizes. The bore and mass are calculated from the nominal dimensions. Use the project tolerance and confirm the size and route in the quote.
| Tube OD (mm) | Wall (mm) | Nominal bore (mm) | Estimated kg/m at 8,000 kg/m³ |
|---|---|---|---|
| 15.88 | 0.89 | 14.10 | 0.34 |
| 19.05 | 1.24 | 16.57 | 0.56 |
| 25.4 | 1.65 | 22.10 | 0.98 |
Use the approved design code and service conditions. The applicable rating depends on material, temperature, minimum effective wall, joint details and the limits of the connected assembly. A schedule or a hydrostatic test result alone cannot establish an operating pressure.

The grade on the purchase line controls chemistry. Specify the grade with the finished product standard or drawing.

|---|---|
| Grade and specification | TP or UNS on the quotation and material report |
| Heat analysis | Full limits and any stabilising or alloy additions under the ordered edition |
Reference ASTM steel standards
Use the ordered grade, delivery condition and product standard to review the actual tensile, yield, elongation or hardness results required by the order.
| Check | What to verify |
|---|---|
| Condition | Heat treatment or cold-work condition stated for the offered form |
| Acceptance | Project-specified dimensions and relevant test records |
Reference ASTM steel standards
State the required eddy-current method, acceptance and tube-end protection.
| When | What to check |
|---|---|
| Before ordering | Document the required test method, edition and any witness points |
| At delivery | Match the material report and heat or lot identification to the shipment |
A179/SA-179 identifies a low-carbon steel option for a separately specified duty.
For the enquiry, provide actual OD, wall basis, tube length and tube-sheet drawing.
Applicable equipment specification, such as A249 for welded austenitic tubing · 15.88 × 0.89 mm. Add quantity, lengths, delivery city and the required reports.
Ordering guidance
For retubing, provide the existing tube drawing, tube OD, specified wall basis, cut length and quantity. If the ends have separate dimensional or finish requirements, identify them on the RFQ.
Specify the nominated grade and tube standard and state whether the order requires a particular route or additional tests. If the original documentation is missing, provide the equipment reference and measured dimensions for review rather than ordering from measurements alone.

Buyer’s guide
Provide actual tube OD, required wall and finished length, then identify whether the tube ends are expanded, welded or joined by another specified method. For a retube, supply the tube-sheet drawing and the original material schedule. The end fit and installation method matter just as much as the total number of tubes.
If previous tubes showed corrosion, deposits or erosion, send the original material records and the operating team’s assessment to the material reviewer. Water chemistry, temperature and flow can influence selection. Keep any proposed alternate alloy or tube route separate from the specified grade when collecting offers.
State the requested examination scope, tube marking, bundle size, end protection and required shipping lengths. If the inspection plan calls for an eddy-current report or another test, include the method and acceptance requirements. Document whether a straight sample or a trial fit is needed before the production lot.
A retube order can list each bank by tube count, actual OD, wall basis, finished length and tube-sheet joint. Attach the material specification and identify any tubes to be supplied first for fit-up.
Add piece count and lengths so the supplier can quote the replacement bundle and the installation crew can match the tube layout.
