Products / LSAW Steel Pipe
Longitudinal seams. Defined requirements.
PRODUCT OVERVIEW
LSAW pipe is made by forming steel plate and welding a longitudinal seam using a submerged arc process. It can be considered where project specifications call for plate-based welded pipe and defined dimensional or inspection requirements.
Confirm plate grade, seam requirements, dimensional tolerances and any toughness requirements with the project engineer.

Supplied company footage illustrates steel pipe and production. Exact product images and order scope are confirmed with the quotation.
TECHNICAL REQUIREMENTS
Size range, materials and applicable standards must be confirmed for the order. No unverified manufacturing limits are presented below.
| Outside diameter | To be confirmed against your project specification |
|---|---|
| Wall thickness | To be confirmed against your project specification |
| Length & tolerance | To be confirmed against your project specification |
| Material / steel grade | To be confirmed against your project specification |
| Product standard & edition | To be confirmed against your project specification |
| Coating / lining | To be confirmed against your project specification |
Send the specified grade, chemical composition requirements, mechanical properties and delivery condition. Availability will be confirmed in the written quotation.
Specify the applicable product standard, edition and any project additions. Standard names are procurement requirements, not a statement of certification or universal compliance.
Include units, tolerances and the standard edition. If your schedule contains several sizes, send the complete list by email after opening the enquiry.
MANUFACTURING & WELDING
Plate preparation → forming → longitudinal seam welding
The manufacturing route, delivery condition and any subcontracted scope are to be confirmed in writing. Align production stages with the project inspection and test plan.
Confirm grade, condition and traceability requirements.
Select the forming route for the agreed pipe specification.
Define the welding procedure and inspection requirements.
Agree the inspection and test plan before production.
Specify surface preparation, coating and acceptance criteria.
Coordinate end protection, lifting and identification.
Confirm destination, shipping terms and required documents.
PROJECT USES
Energy projects · Pressure pipelines · Structures
Confirm plate grade, seam requirements, dimensional tolerances and any toughness requirements with the project engineer.
EXPLORE APPLICATIONSINSPECTION & DOCUMENTATION
Select the applicable checks with the project engineer. Testing methods, coverage and acceptance criteria are subject to the agreed product standard and contract.
Review identification, material certificates and the specified chemistry and mechanical properties.
Define process controls, weld examination and acceptance criteria for the chosen product route.
Specify method, coverage, acceptance level and reporting requirements in the inspection plan.
Confirm test applicability, pressure, hold time and witnessing requirements against the product specification.
Check the agreed diameter, wall thickness, length, straightness, ovality and end preparation.
Agree surface preparation, thickness, adhesion and holiday testing where the coating system requires them.
Review appearance, quantities, marking, protection and release documentation before dispatch.
Define the material records, test reports, inspection release and packing list required with the order.
COATING & PACKING
Coating, lining and field joint details should form a coordinated system. Specify service environment, design temperature, surface preparation, thickness and inspection requirements. For bare pipe, agree storage and temporary protection requirements.
Confirm pipe marking, end protection, lifting methods, bundling or loose loading, and coating contact protection. Packing lists and shipping documents should match the agreed delivery scope. Destination, unloading constraints and the requested trade terms are useful inputs for your enquiry.
DISCUSS YOUR PIPE PACKAGEFAQ
Send the required outside diameter, wall thickness, length, material grade and quantity. We will confirm availability and the applicable supply scope in a written quotation. Published size limits will be added only after verification.
Specify the required standard and edition, along with any certification or inspection documents needed. These requirements must be checked for the particular order. This page does not imply API, ISO or other certification.
Include internal lining, external coating, end cutback, bevel or plain-end requirements in the enquiry. Compatibility, availability and acceptance criteria will be reviewed before confirmation.
Price and schedule depend on the verified specification, quantities, inspection scope, finishing and destination. They are confirmed in a formal quotation; the website does not publish an assumed stock level or lead time.
