API 5L pipe: choose grade, PSL and manufacturing route
Product option	Application	Order details
Grade and PSL	API 5L line pipe is specified by grade and product specification level.	Write PSL1 or PSL2 explicitly and identify delivery condition. Do not infer project suitability from the grade alone.
Seamless or welded	The project specification determines which manufacturing routes are permitted.	State the route with OD, wall thickness, length, ends and coating. Compare quotations on the same basis.
Inspection and service	Mechanical, chemical and nondestructive test requirements depend on the ordered specification.	Define the applicable edition, service restrictions and any additional inspection requirements in the purchase order.

Inspection and shipment documents

Link pipe markings, heat identity and the mill certificate. Confirm the ordered PSL, dimensional inspection, hydrostatic and NDT requirements before accepting the inspection plan.

Overview

Specify API 5L line pipe by edition, exact grade, PSL1 or PSL2, delivery condition and permitted manufacturing route. Use the project specification to select seamless or welded pipe; a matching grade and size does not approve substitution.

Give outside diameter, nominal wall thickness, length and tolerances. For NPS and schedule, identify the dimensional reference. Define end preparation, coating or lining, cutbacks and coating acceptance where applicable.

State service conditions and supplementary toughness or sour-service requirements. PSL2 alone does not establish suitability for sour service. Define applicable tests, sampling, acceptance criteria and inspection documents with heat and pipe identification.

Send quantity by line item, destination port, delivery date and unloading limits. Agree end protection, bundle or piece weight and storage protection. Confirm availability, document scope, packing and delivery terms in the quotation.

FAQ

What must an API 5L line-pipe enquiry specify?

State the API 5L edition, exact grade, PSL1 or PSL2, delivery condition and permitted manufacturing route. Add outside diameter, nominal wall thickness, length and tolerances. If using NPS and schedule, identify the dimensional reference. Include quantity, end preparation, coating, inspection documents and destination port.

Can seamless and welded API 5L pipe be substituted?

Use the route permitted by the project specification. State seamless or the required welded route explicitly. Matching grade, outside diameter and wall thickness does not approve a change of route. Any proposed substitution requires the buyer’s technical approval before the order is changed.

Does PSL2 alone establish sour-service suitability?

PSL2 is a product specification level. It does not, by itself, approve pipe for the project’s sour-service conditions. Provide the service specification and any additional chemistry, hardness, toughness, HIC or SSC testing requirements for technical review. Define test methods, sampling and acceptance criteria where required.

Which inspection and shipment documents should I request?

Specify the required inspection certificate, heat and pipe identification, dimensional results, mechanical tests and applicable hydrostatic and nondestructive examination records. Include coating records and witness or hold points when required. Confirm document availability, inspection scope and any third-party involvement in the quotation and purchase order.

Seamless Steel Pipe

Specify seamless steel pipe by standard, grade, outside diameter, wall thickness and delivery condition. Define the service and inspection requirements before comparing pressure, process or mechanical pipe quotations.
