Start with the project specification
State the standard and edition, grade, application and required PSL 1 or PSL 2 for API 5L line pipe.
LEKE PIPING / STEEL PIPE SUPPLY
Steel Pipe Supply
API 5L line pipe supplied through partner mills, plus carbon, stainless and alloy steel pipe options.
PRIMARY SUPPLY FOCUS
API 5L Line Pipe
Specify the API 5L edition, grade and Product Specification Level (PSL 1 or PSL 2).
Include pipe type, outside diameter, wall thickness, length, delivery condition and end preparation. State any project testing, marking or inspection document requirements.
LeKe Piping acts as the supplier, not the API-licensed pipe mill. Where API licensing is required, confirm the producing mill, licence scope and order documentation before purchase. Supply to API 5L alone does not establish certification.
| Parameter | Details to confirm |
|---|---|
| Specification | API 5L; state the required edition |
| Grade and PSL | Provide the specified grade and PSL 1 or PSL 2 requirement |
| Pipe type | State seamless or the required welded pipe type |
| Dimensions | Outside diameter / nominal size, wall thickness and length |
| Delivery | End preparation, delivery condition, coating, quantity and required delivery date |
| Documents | Mill test certificate, heat traceability, testing and third-party inspection requirements |
BEFORE QUOTATION
A complete steel pipe enquiry.
Define the pipe
Specify outside diameter, wall thickness, length range or fixed length, and seamless or welded pipe type.
Confirm supply conditions
List quantity, ends, delivery condition, coating, destination, delivery date and required inspection documents.
Custom requirements. Custom outside diameters, wall thicknesses, lengths and end preparations can be reviewed against your specification. Send your grade, PSL and dimensional requirements with your RFQ. Primary reference: API 5L for the line-pipe supply focus; confirm grade, PSL and edition.
MATERIAL OPTIONS
Carbon Steel Pipe
For carbon steel pipe requirements outside the API 5L focus above, provide the exact standard and grade. Material and specification are different dimensions; confirm the required pipe type and supply conditions.

COMMON QUESTIONS
Prepare a clearer steel pipe RFQ.
What should I send for a steel pipe enquiry?
Include material grade, standard, pipe type, diameter, wall thickness, length, quantity and inspection documents. For line pipe, include the specified PSL where applicable.
Do you supply other steel pipe?
Yes. This page also covers other carbon steel, stainless steel and alloy steel pipe requirements. The actual grade and supply scope are confirmed against your enquiry.
Do all pipe materials follow the same standard?
Use the actual governing standard and grade for each pipe item. Do not assume all pipe materials on this page follow the same specification.
Can one enquiry include carbon, stainless and alloy steel pipe?
Yes. Separate the items in the material list and state the actual specification, grade and dimensions for each. Do not apply a line-pipe designation to every material group.
What length and quantity information should I provide?
State the required length per piece, number of pieces or total length, and any acceptable length tolerance. Identify fixed-length or variable-length requirements explicitly.
What information is needed for a coating or end-protection request?
Provide the coating system, surface preparation and inspection requirements, plus the required end protection and packaging. Availability and scope must be confirmed against the enquiry.
Does the weight calculator give the final shipping weight?
No. It estimates pipe material weight from dimensions and density. Coatings, packing, dimensional variation and other shipment items can change the actual shipping weight.
PIPE WEIGHT TOOL
Estimate weight from your dimensions.
Use actual outside diameter, wall thickness, length and density for a preliminary theoretical weight.

Match the material to the service.
| Parameter | Details to confirm |
|---|---|
| Carbon steel pipe | Confirm the service, grade, product standard, manufacturing form, diameter and wall thickness. API 5L line pipe requirements are reviewed in the section above. |
| Stainless steel pipe | State the exact grade, corrosion or cleanliness requirements, surface finish, ends and documentation. Do not specify by stainless appearance alone. |
| Alloy steel pipe | State the alloy grade, service temperature, delivery condition, product standard and any heat-treatment or testing requirements. |
| Special material requirements | Send the grade, governing specification and approved drawing. Supply availability and manufacturing scope require confirmation. |
