| Procurement Item | Details |
|---|---|
| Applicable Standard | ASTM A53/A53M Type E Grade B |
| Product Category | Steel Pipes & Tubes / Welded Pipe |
| Dimensions & Quantity | The sizes below are enquiry references. Available combinations, quantities and delivery times are subject to written quotation. |
| Documentation | Specify heat/batch inspection documents, standard edition, traceability and project certification in your enquiry. Documents are subject to confirmation of actual availability. |
01 / Product Features & Selection
- State Type E and Grade B explicitly; an A53 designation alone does not define the manufacturing route.
- Common Sch 40 / Sch 80 sizes support coordination with fittings, flanges and installation lists.
- Specify black, galvanized or subsequently coated pipe according to the application and connection process.
02 / Specifications, Dimensions & Ordering Options
These dimensions help define your purchase requirement; they do not imply that every combination is in stock. Specify tolerances, quantity, delivery condition and destination port. Submit drawings for special sizes.
| Parameter | Specification / Enquiry Range | Points to Confirm |
|---|---|---|
| Size Designation | NPS + Schedule, or actual OD × wall thickness WT | Specify nominal or minimum wall thickness. |
| Common Outside Diameters / mm | 21.3, 26.7, 33.4, 42.2, 48.3, 60.3, 73.0, 88.9, 114.3, 168.3, 219.1, 273.0, 323.9 | Do not mix EN 10255 diameters of 76.1 / 165.1 with ASME dimensions. |
| Length / m | 6, 12; fixed or random lengths by enquiry | Specify individual length tolerance and end squareness. |
| Pipe Ends | Plain, bevelled or project-specific | Confirm bevel angle, root face and end caps against drawings. |
| Surface | Black, temporary rust-preventive oil or other agreed protection | Temporary surface protection does not replace the final service corrosion design. |
Common NPS / DN and Schedule Dimensions
Common ASME B36.10M reference dimensions, in mm. DN is a nominal designation, not the actual outside diameter. Check the full standard for larger sizes or other schedules.
| NPS / in | DN | Actual Outside Diameter OD | Sch 40 Nominal Wall Thickness | Sch 80 Nominal Wall Thickness |
|---|---|---|---|---|
| 1/2 | 15 | 21.3 | 2.77 | 3.73 |

| 12 | 300 | 323.9 | 10.31 | 17.48 |
03 / Standard Chemical Composition
ASTM A53/A53M Type E Grade B. Values are mass percentages (%). Maximum limits are shown by ≤, minimum limits by ≥; ranges are specification limits and Fe is the balance. These are not measured results for a current delivery heat.
| Element / Indicator | Requirement or Range |
|---|---|
| C | ≤0.30 |
| Mn | ≤1.20 |
| P | ≤0.050 |
| S | ≤0.045 |
| Cu | ≤0.40 |
| Ni | ≤0.40 |
| Cr | ≤0.40 |
| Mo | ≤0.15 |
| V | ≤0.08 |
| Fe | Balance |
Heat analysis, mass %, from Pacific Pipe public A53 Grade B data. Cu+Ni+Cr+Mo+V total ≤1.00%. Confirm carbon-reduction / manganese-increase rules and all limits against the contractual edition.
04 / Mechanical Properties & Application Limits
| Thickness / Material Condition | Yield Strength Re / Rp0.2 (MPa) | Tensile Strength Rm (MPa) | Elongation After Fracture A (%) |
|---|---|---|---|
| Type E Grade B, room temperature | ≥240 | ≥415 | As determined by the standard specimen and formula |
Strength in MPa. Weld heat treatment, flattening / bending, individual hydrostatic or applicable electrical testing must match the manufacturing type and size. Rated pressure requires project design approval.
05 / Inspection, Processing & Quality Checks
- Verify weld treatment, tensile, flattening / bending and individual-pipe inspection. A coil certificate does not replace finished-pipe testing.
- Check OD and wall tolerances against the specified edition, especially minimum wall and weld areas.
- A hydrostatic test record is not a service pressure rating. Confirm actual conditions under the piping design code.
- Ends, threads, bevels and coatings must suit the customer's connection process.
06 / Export Packaging for This Product
| Stage | Recommended Arrangement | Key Considerations |
|---|---|---|
| End Protection | Use end caps, bevel guards or thread protectors appropriate to the pipe ends. | Keep stainless steel surfaces free of carbon-steel particles and chloride contamination. |
| Size-Separated Bundles | Bundle by OD, wall thickness, length and heat/batch, with durable identification. | Use liners or supported crates for small-diameter thin-wall tubes where appropriate. |
| Transport Support | Multiple supports, strap padding, anti-roll chocks and securing arrangements. | Keep long lengths properly supported; verify package weight and length before loading. |
Before shipment, cross-check product, grade, heat number, size, piece count, net weight and gross weight against the packing list. Match labels to inspection documents. For solid-wood pallets, dunnage or crates, check destination-country rules; wood subject to ISPM 15 must be treated and marked by an approved provider. Load dry cargo and arrange supports, blocking and securing according to weight and centre of gravity.
07 / How Qida Supports Your Procurement
| Procurement Stage | Qida Coordination | Information for the Buyer |

| Delivery Coordination | Coordinate production / sourcing progress, labels, packing lists and shipping documents. | Check dimensions, quantities and heat/batch correspondence at agreed milestones. |
| After-Sales Follow-Up | Review issues using order number, heat number, arrival photographs and test records. | A defined issue description and documented resolution communications. |
Qida focuses on clear specifications, material requirement checks and delivery coordination. Include cutting, cut-to-length, surface treatment, third-party inspection and certificate requirements in your enquiry so that the achievable scope can be agreed before order placement.
