| Procurement Item | Details |
|---|---|
| Applicable Standard | EN 10255 / S195T（1.0026） |
| Product Category | Steel Pipes & Tubes / Galvanized 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
- H-series wall thickness is listed for each nominal size to support weight, connection and clearance calculations.
- Distinguish procurement by wall series within the same steel grade; M/H do not describe material strength classes.
- Review grooving and threading before quotation to reduce connection rework after arrival.
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 Range | DN10–DN150; detailed OD and M/H walls below | Standard dimensional references; confirm available OD / wall combinations before quotation. |
| Series | H Series (heavy wall) | Do not assume equivalence to American Sch 40 / Sch 80. |
| Length / m | 6 or project fixed lengths | Plain-end length and total length including sockets have different measurement bases. |
| Ends / Connections | Plain, grooved or EN 10226-1 threaded ends by enquiry | Confirm thread form, socket material and sealing method. |
| Coating Requirements | Hot dip galvanized; specific EN 10240 quality class by service agreement | For drinking water, check destination-country contact-material / hygiene requirements separately. |
| Acceptance Documents | Base-pipe grade, dimensions, inspection and coating records as ordered | Inspect coating thickness, internal surfaces and ends separately. |
| Nominal Thread Size / in | DN | Actual OD / mm | M Wall Thickness / mm | H Wall Thickness / mm |
|---|---|---|---|---|
| 1/4 | 10 | 17.2 | 2.3 | 2.9 |
| 1/2 | 15 | 21.3 | 2.6 | 3.2 |

03 / Standard Chemical Composition
EN 10255 / S195T（1.0026）. 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 | ≤0.20 |
| Mn | ≤1.40 |
| P | ≤0.035 |
| S | ≤0.030 |
| Fe | Balance |
Heat analysis, mass %, for the steel base pipe. Agree the specific EN 10240 coating class separately; +Z sheet / coil designations do not replace pipe coating requirements.
04 / Mechanical Properties & Application Limits
| Thickness / Material Condition | Yield Strength Re / Rp0.2 (MPa) | Tensile Strength Rm (MPa) | Elongation After Fracture A (%) |
|---|---|---|---|
| EN 10255 base pipe, room temperature | ≥195 | 320–520 | ≥20 |
Strength in MPa, elongation in %. M and H are dimensional / wall series, not higher steel grades. Confirm medium, temperature, pressure, connection and local approvals in the project specification.
05 / Inspection, Processing & Quality Checks
- Check actual EN 10255 diameters including 26.9, 33.7, 76.1 and 165.1; avoid mixing ASME dimensions.
- After galvanizing, inspect bare areas, zinc runs, end buildup, internal surfaces and connection fit.
- Include white-rust and transport-condensation protection. Galvanized appearance does not guarantee a fixed corrosion life.
- Verify hydrostatic / applicable electrical testing, ends and labels. Service pressure and hygiene approvals follow local project requirements.
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 |
|---|---|---|
| Requirement Review | Review application, standards, material condition, drawings and acceptance items. | A checkable specification list helps reduce language and unit-conversion errors. |
| Order Confirmation | Confirm material, processing, inspection, packaging, delivery milestones and cost responsibilities item by item. | A clear written quotation and mutually agreed purchase requirements. |
| 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.
