S195T Galvanized Threaded Steel Pipe | EN 10255
Galvanized round pipe with threaded-end options for compatible conveyance and mechanical installations. This enquiry version focuses on thread form, socket fit, coating class and end protection, so the buyer can specify a connection-ready package rather than only pipe diameter.
| Ordering item | Specification |
|---|---|
| Material / standard | EN 10255 base pipe / EN 10240 galvanized coating |
| Product family | Galvanized Pipe |
| Supply basis | Enquiry-based grade, dimensions, processing and quantity; availability, MOQ and delivery confirmed in the quotation. |
| Inspection documents | Request heat/batch records and EN 10204 3.1 or other documents where required; actual document scope must be confirmed. |
01 / Selection Advantages
- Order thread standard and socket requirements together to avoid incompatible field connections.
- Specify internal and external coating acceptance where the service requires both surfaces.
- Separated size bundles and protected threads support efficient unloading and connection checks.
02 / Specifications & Size Schedule
Use the following options to prepare a complete enquiry. The lists do not imply that every dimension combination is stocked or interchangeable with another standard. State the required tolerances and quantity for each line.
| Parameter | Enquiry requirement |
|---|---|
| Series | M medium or H heavy wall; select one series in the purchase schedule |
| Length / m | 6 or agreed fixed lengths; specify with/without socket measurement basis |
| Threads | ISO 7-1 / EN 10226 R/Rp connection by agreement; ASME NPT is a separate enquiry |
| Ends | Threaded both ends with socket and protector options; confirm actual scope |
| Service approval | Potable-water or fire-system approval is destination/project-specific and must be agreed |
| 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 |
| 3/4 | 20 | 26.9 | 2.6 | 3.2 |
| 1 | 25 | 33.7 | 3.2 | 4.0 |
| 1¼ | 32 | 42.4 | 3.2 | 4.0 |
| 1½ | 40 | 48.3 | 3.2 | 4.5 |
| 2 | 50 | 60.3 | 3.6 | 4.5 |
| 2½ | 65 | 76.1 | 3.6 | 5.0 |
| 3 | 80 | 88.9 | 4.0 | 5.0 |
| 4 | 100 | 114.3 | 4.5 | 5.4 |
| 5 | 125 | 139.7 | 5.0 | 5.4 |
| 6 | 150 | 165.1 | 5.0 | 5.4 |
03 / Chemical Composition
Composition is expressed in weight percent. Maximum and minimum limits refer to the listed grade/product reference; final acceptance follows the agreed standard edition and heat analysis.
| Element | Grade reference / wt.% |
|---|---|
| C | ≤0.20 |
| Mn | ≤1.40 |
| P | ≤0.035 |
| S | ≤0.030 |
| Fe | Balance |
04 / Mechanical Properties & Technical Notes
| Condition | Min yield / MPa | Tensile / MPa | Min elongation |
|---|---|---|---|
| S195T base pipe | 195 | 320–520 | 20% |
DN and thread size are nominal designations; use actual OD and wall for dimensional checks. M/H series are not automatically interchangeable with American schedules. Confirm sealant compatibility, coating quality class and any destination-specific hygiene requirements.
05 / Processing & Inspection
| Control point | What to agree or inspect |
|---|---|
| Thread inspection | Confirm taper/parallel arrangement, thread gauge standard and socket engagement. |
| Base pipe | Review heat identification, wall, OD, length and leak-tightness test requirements. |
| Galvanizing | Agree coating class, internal finish, bare spots and permissible repairs. |
| Final ends | Protect threads and remove harmful zinc build-up where specified. |
Include additional tests, third-party inspection, marking transfer and processing requirements before order confirmation. Qida can coordinate the agreed inspection scope and supporting records; an online product guide is not a delivered-batch test certificate.
06 / Export Packaging & Transport
| Packing item | Practical requirement |
|---|---|
| Thread protection | Fit suitable caps/protectors; isolate loose sockets to prevent transit damage. |
| Dry storage | Keep bundles ventilated and dry to reduce wet-storage staining. |
| Handling | Use suitable slings and separators to limit zinc-surface abrasion. |
| Dispatch marks | Show DN, series, thread type, length, quantity and order/lot reference. |
Agree destination port, Incoterms rule and named place, package mass, unloading equipment and required shipping documents. Container capacity depends on payload limits, route and load distribution. For regulated solid-wood packaging, confirm the applicable ISPM 15 treatment and marking requirements.
07 / Qida Procurement Support
| Order stage | Our coordination | Buyer benefit |
|---|---|---|
| Specification review | Review material, dimensions, units, drawings and destination requirements. | A clear line-by-line enquiry helps reduce omissions and incompatible substitutions. |
| Processing plan | Confirm cutting, finishing, inspection and identification items in writing. | The buyer can assess scope and acceptance before production or sourcing proceeds. |
| Packing & dispatch | Coordinate labels, packing list, suitable protection and shipping-document requirements. | Piece count and heat/lot correspondence can be checked at agreed milestones. |
| After-sales follow-up | Review order references, arrival photos and inspection records for reported issues. | A documented issue description supports a specific response and follow-up. |
08 / Request a Detailed Quotation
Send the standard and edition, grade, size schedule, quantity per size, material condition, finish, processing drawings, tests/documents, packing requirements and destination port. Include maximum piece or package weight and any project approval requirements. Pricing, minimum quantity and lead time will be confirmed against the actual requirement.
