ABS Certified LSAW Steel Pipe for Marine and Offshore Projects
Jiangyin, Jiangsu, China – September 16, 2026
Premium ABS Certified LSAW Steel Pipe
Our ABS certified LSAW steel pipe is manufactured for demanding marine, offshore and heavy structural applications where reliable welding quality, mechanical performance and material traceability are essential. Manufactured using EQ47R steel grade, this large-size, heavy-wall pipe is produced in accordance with the applicable requirements of ABS Rules 2019 and AWS D1.1:2015 specifications.
Longitudinal Submerged Arc Welding (LSAW) technology is well suited to the production of large-diameter and heavy-wall Steel Pipes. The manufacturing process provides a longitudinal welded structure designed for applications requiring substantial pipe dimensions and dependable fabrication quality.
EQ47R Steel Grade for Marine Applications
The use of EQ47R steel grade makes this LSAW steel pipe suitable for projects where the selected material specification requires defined mechanical properties and controlled manufacturing requirements.
For marine and offshore projects, material selection is particularly important because steel components may be exposed to demanding service and fabrication conditions. Our EQ47R Lsaw Pipes are supplied according to the specified project requirements, with attention to material identification and production traceability.
Large-Diameter and Heavy-Wall LSAW Pipe
This product is available as a large-size, heavy-wall LSAW steel pipe, making it suitable for applications where larger dimensions and substantial wall thickness are required.
The pipe can be considered for a variety of industrial and structural applications, including:
- · Marine engineering projects
- · Offshore construction
- · Heavy structural projects
- · Marine structures
- · Offshore infrastructure
- · Large-scale pipeline applications
- · Industrial construction projects
The appropriate pipe outside diameter, wall thickness, steel grade and other specifications can be selected according to the engineering requirements of each project.
Complete Heat and Pipe Number Traceability
Material traceability is an important consideration when purchasing steel pipe for engineering and construction projects. Our ABS certified LSAW steel pipes can be supplied with heat and pipe number identification to support material tracking throughout production and inspection.
Heat number and pipe number traceability helps connect individual pipes with their relevant manufacturing and inspection records. This provides project teams with clearer material identification during quality control, inspection and project documentation.
Welding Quality and Mechanical Properties
LSAW steel pipe is manufactured using a longitudinal submerged arc welding process. For heavy-wall and large-diameter pipe applications, welding quality is an important part of the overall product specification.
Our ABS LSAW steel pipe is produced according to the applicable requirements specified for the project, with the relevant welding and material requirements considered during manufacturing and quality control.
This makes the pipe a suitable option for buyers looking for a heavy-duty steel pipe for marine, offshore and structural engineering applications.
Applications of ABS Certified LSAW Steel Pipe
With its large-size construction, heavy-wall design, EQ47R steel grade and traceability requirements, this LSAW pipe can be used for projects involving:
- · Marine and offshore engineering
- · Heavy structural applications
- · Offshore infrastructure
- · Marine construction
- · Industrial engineering
- · Large-scale steel structures
- · Pipeline and tubular engineering
