Octal Pipe completed the delivery of 42-inch API 5L X56 PSL2 welded pipes to Batam Port, Indonesia. The pipes were supplied for a large-diameter pipeline project requiring heavy-wall construction, controlled dimensions and stable pipe geometry.
Each pipe has an outside diameter of 42 inches, equivalent to 1,066.8 mm, and a wall thickness of 2 inches, equivalent to 50.8 mm. For pipe of this size and wall thickness, dimensional consistency is important during transportation, site handling, alignment and field welding.

API 5L X56 PSL2 Welded Pipe Specifications
The main specifications of the supplied pipes include:
- Product: Welded line pipe
- Standard and grade: API 5L X56 PSL2
- Outside diameter: 42 inches (1,066.8 mm)
- Wall thickness: 2 inches (50.8 mm)
- Destination: Batam Port, Indonesia
- Key dimensional requirement: Pipe ovality controlled within 4 mm
Large-diameter heavy-wall welded pipes for pipeline applications.
Stable pipe-end geometry supports alignment and field welding.
API 5L X56 PSL2 welded pipe is used in pipeline transmission systems where material strength, dimensional control and project traceability must meet the specified technical requirements.
The 42-inch outside diameter provides the flow capacity required by large pipeline systems, while the 2-inch wall thickness supports the mechanical demands defined by the project design.
Ovality Control for 42-Inch Welded Pipe
Pipe ovality describes the difference between the largest and smallest outside diameters measured across the same pipe section. Excessive ovality can create problems when two large-diameter pipes are aligned for field welding.
For this order, pipe ovality was controlled within 4 mm. Compared with the nominal outside diameter of 1,066.8 mm, this was a particularly important dimensional requirement for maintaining a consistent circular profile.
Controlled ovality helps the installation team:
- Align adjoining pipe ends.
- Control internal and external mismatch.
- Position field-welding equipment correctly.
- Maintain a more consistent joint gap.
- Reduce adjustment work during pipeline installation.
The requirement becomes increasingly important as pipe diameter and wall thickness increase. Heavy-wall pipe is more difficult to correct or reshape at the construction site, so dimensional control must be addressed before shipment.
Dimensional Control for Heavy-Wall Welded Pipe
The combination of a 42-inch outside diameter and a 2-inch wall thickness requires close control of the pipe-forming process. Variations in forming can affect outside diameter, roundness, pipe-end geometry and the alignment of adjoining pipe sections.
For this project, dimensional attention was therefore focused on the pipe diameter, wall thickness and ovality requirement specified for the order. Stable geometry helps ensure that the pipes can be handled, positioned and connected according to the pipeline installation plan after arrival in Indonesia.
The pipe grade, size and project identification also need to remain traceable throughout preparation and delivery so that the receiving team can match each pipe with the relevant order information.
Delivery to Batam Port, Indonesia
Large-diameter heavy-wall pipes require careful planning during storage, lifting and transportation. Their weight and dimensions make loading arrangements different from those used for conventional small-diameter pipe.
The API 5L X56 PSL2 welded pipes were prepared for delivery to Batam Port with attention to pipe support and handling. Suitable lifting positions and supports help avoid concentrated loads that could damage pipe ends or affect the pipe geometry during transportation.
This shipment demonstrates Octal Pipe's ability to coordinate large-diameter welded line pipe orders with demanding dimensional requirements. Octal Pipe supplies API 5L welded pipe in multiple grades, diameters and wall thicknesses for oil, gas, water and other pipeline transmission projects.
