These references explain product selection. Availability, dimensions, minimum order quantity and delivery time depend on the requested specification and are confirmed in the quotation and purchase order.

Compare ERW, LSAW and SSAW manufacturing routes
Selection reference	Typical use or scope	What to check
ERW	A longitudinal seam formed by electric-resistance welding, commonly from strip or coil.	Review weld heat treatment where required, seam inspection and the permitted product standard.
LSAW	Plate formed into pipe with a longitudinal submerged-arc-welded seam.	Review plate traceability, forming route, seam inspection and end geometry against the project requirements.
SSAW / HSAW	Strip or coil formed helically with a spiral submerged-arc-welded seam.	Check whether the project permits a helical seam and define seam inspection and dimensional acceptance.
Shared quotation basis	Compare proposals using the same grade, OD, wall, length, service and inspection scope.	For API 5L orders include PSL and delivery condition. Keep structural and pressure-service requirements separate.

Inspection and shipment documents

Compare the inspection plans alongside price: base-material identity, seam test method and coverage, dimensional acceptance, hydrostatic testing where required, coating inspection and final document pack. Obtain project approval before changing the manufacturing route.

Overview

ERW, LSAW, and SSAW welded pipe routes are selected around diameter, wall, service, project standard, mill capability, and the accepted weld inspection plan. The manufacturing abbreviations do not establish interchangeability. Pipeline buyers should state API 5L PSL level and coating requirements, while structural buyers should state the structural standard, grade, section duty, and dimensional tolerances. Send the complete order designation, dimensions, quantity, inspection requirements, packing method, and destination port. The quotation can then address availability, production timing, EN 10204 3.1 documentation, inspection options, export packing, and delivery terms for the requested specification. ERW / LSAW / SSAW Steel Pipe is selected for purchasing programs that need a clearly defined Pipe, material identity, and order specification. For an actionable quotation, state quantity, destination port, application, packing, inspection, and document requirements. Add forming, welding, corrosion exposure, load, service temperature, or fabrication details when they affect product selection.

Product scope

Grade and standard are selected from the project specification; cross-standard equivalence is not assumed.
Pipe dimensions, surface, processing, inspection, and documents are confirmed from the RFQ.

Applications

Onshore pipeline and utility transmission packages
Large-diameter water and piling projects
Structural pipework where a welded route is permitted

Surface options

Bare or shop-coated
FBE, 3LPE, 3LPP, or other external coating by specification
Internal lining or flow coat by project requirement

Processing & form

Plain or beveled ends
Fixed-length cutting
External coating and internal lining
Hydrostatic testing and weld NDT by PO

RFQ documents & delivery

Packing, MTC, and inspection path — include them in your RFQ for an actionable quote.

Packing & delivery

Export packing options

Pipe and hollow-section lots are bundled by size and heat or lot where traceability is required. Export packing can include steel straps, waterproof wrapping, lifting points, bevel or thread protectors, end caps, and durable shipping marks. Bundle weight, loose-loading restrictions, container limits, discharge method, destination port, and any break-bulk lashing plan are confirmed before loading.

Quality assurance

Quality documents

Inspection is agreed against the purchase order, governing product standard, and any approved inspection and test plan. The review can cover grade and heat identity, dimensions, wall thickness, end preparation, visual condition, coating, hydrostatic testing, and NDT records where applicable. EN 10204 3.1 documentation and third-party witness points must be requested before production is released.

Export packing & loading evidence

Representative export packing and loading evidence. Final packing follows the approved order.

Supply confidence

Stock, inspection, and product uses

Review warehousing, inspection, and product uses, then add quantity, port, and inspection needs to your RFQ.

Steel bundles staged by lot in the warehouse

Warehouse & staged stock

Strapped coils and plates staged by lot so grade, thickness, and destination port can be matched quickly for shipment.
