Octal Pipes completed a line pipe delivery project to Port Harcourt, Nigeria, covering API 5L X52M concrete weight coating pipe and API 5L X52 seamless pipe with 3LPE coating. The order included multiple pipe sizes, including 28 inch, 2 inch, 4 inch, 6 inch and 8 inch, with wall thickness requirements covering SCH40, XS and 80.
For offshore, coastal or buried pipeline projects, the delivery control is not only about pipe grade. Coating type, pipe marking, wall thickness, package identity, inspection records and shipment documents all need to match the order before cargo release.

Line Pipe Products Supplied
The shipment covered two main product groups for pipeline construction and project delivery:

- API 5L X52M Concrete Weight Coating Pipe (CWC)
- API 5L X52 Seamless Pipe with 3LPE coating
- Wall thickness schedules: SCH40, XS and 80
- Export shipment arranged to Port Harcourt, Nigeria
- Multiple pipe sizes: 28 inch, 2 inch, 4 inch, 6 and 8 inch
The 28 inch CWC pipe was the key heavy-coated line pipe item in this delivery. Smaller seamless pipe sizes such as 2 inch, 4 inch, 6 inch and 8 inch were included to support project piping needs under the same shipment arrangement.
API 5L X52M Concrete Weight Coating Pipe
API 5L X52M CWC pipe is used where line pipe needs extra weight, external protection and better stability during handling, laying and service, especially for offshore, coastal or water-crossing pipeline sections.
For CWC pipe orders, Octal Pipe can support API 5L X52M pipe supply, concrete weight coating coordination, coating appearance check, OD and wall thickness verification, pipe end protection, marking review, packing-list matching and export document preparation.
Before shipment, Octal Pipe checks that the pipe, coating condition, marking, packing list and inspection records match the order requirements. MTC, coating inspection records, dimensional reports, packing list, shipment documents and third-party inspection coordination can be provided when required.

API 5L X52 Seamless Pipe with 3LPE
API 5L X52 seamless pipe with 3LPE coating was also included in this Nigeria delivery. 3LPE coating is commonly selected for buried or corrosion-sensitive pipeline service, where external anti-corrosion protection is required.
For coated seamless pipe, Octal Pipe supports review of pipe body marking, coating appearance, end cutback condition, size identification, packing list consistency and document matching. These checks help reduce receiving disputes and make site handover easier after arrival.
Shipment Checking and Export Service
Before shipment, Octal Pipe arranged product identification review, size checking, coating condition review, packing-list matching and export document preparation. For mixed line pipe shipments, this step is important because CWC pipe and 3LPE coated seamless pipe have different handling and inspection points.


Octal Pipe can support the shipment with MTC, packing list, inspection records, coating-related records, marking photos and shipment documents. When the project requires it, third-party inspection coordination and pre-shipment visual records can also be arranged before cargo release.
Delivery Support for Nigeria Pipeline Projects
This delivery to Port Harcourt shows Octal Pipe’s ability to supply coated line pipe packages for international pipeline projects. The order combined API 5L X52M CWC pipe and API 5L X52 seamless pipe with 3LPE, covering both large-diameter and smaller-size pipe requirements.
For similar projects, buyers should confirm pipe grade, OD, wall thickness schedule, coating standard, coating type, end protection, marking requirement, inspection scope, packing method and document package before shipment release.
