Source API 5L X80 Pipe to specification
Build a supplier-comparable enquiry by defining outside diameter / NPS, schedule or wall thickness, seamless or welded route, end preparation, length and testing, material designation, governing standard and edition, quantity, destination, acceptance criteria and required certification.
RFQ definition: outside diameter / NPS, schedule or wall thickness, seamless or welded route, end preparation, length and testing.
Typical family applications: oil and gas, pressure equipment, automotive, machinery, shafts, gears, structural and general engineering applications. Suitability remains the buyer's engineering decision.
API 5L X80 Pipe sizes and dimensions to specify
Useful enquiry selectors—not an inventory or universal availability claim. Exact manufacturability is confirmed against grade, standard, route, tolerance and quantity.
Common RFQs reference ASME B36.10M or ASME B36.19M where applicable; the purchase order must identify the exact product and material standard.
Range guide: Common enquiry selectors: NPS 1/8 to NPS 24, with larger sizes treated as project-specific capability checks.
| Wall / schedule | 5S, 10S, 40S, 80S, 160 or XXS where the selected standard and manufacturing route permit |
|---|---|
| Manufacturing route | Seamless / welded / fabricated as specified |
| Length and ends | Single / double random or fixed length; plain, bevelled or threaded ends as required |

API 5L X80 pipe RFQ checks
State the applicable API 5L edition, PSL where applicable, outside diameter, wall thickness, length, required manufacturing route, end finish, coating and destination.
If impact testing, NDT, hydrostatic testing, sour-service controls or other project-specific requirements apply, put them in the RFQ. Supplier comparison must use the same approved technical basis rather than the grade name alone.

How we compare API 5L X80 Pipe manufacturers
Grade designation, heat traceability and required certification are matched to the RFQ.
Route, size range, tolerances, heat treatment and form-specific capability are checked.
Dimensional, visual, PMI / chemistry, mechanical or NDT controls are defined where applicable.
MTC, inspection records, packing and export documents are aligned before dispatch.
No material grade, route, standard or dimension substitution without written buyer approval.
Supplier offers are compared on the same technical basis before commercial selection.
API 5L X80 Pipe sourcing questions
How do I source API 5L X80 Pipe from India?
Send the exact material designation, product standard, outside diameter / NPS, schedule or wall thickness, seamless or welded route, end preparation, length and testing, quantity, destination and required inspection. India Supply Solutions then identifies and compares suitable Indian manufacturers or suppliers.
How do I compare the qualified API 5L X80 Pipe manufacturers in India?
Compare actual capability for the named grade and form, applicable standard, traceability, test documentation, delivery record, inspection readiness and commercial transparency—not only the lowest quoted price.
Can you quote API 5L X80 Pipe price in India?
Yes, after grade, standard, dimensions, quantity, packing and delivery basis are defined. We do not publish a fabricated fixed price for specification-sensitive metal products.
What documents should be requested for API 5L X80 Pipe?
Depending on the requirement, buyers may request MTC / heat traceability, inspection records, PMI or chemistry verification, mechanical tests, NDT and packing / export documents.
