Octal Pipe

Octal Pipe CWC Pipe refers to line pipe supplied with concrete weight coating (CWC) to add negative buoyancy and improve stability for offshore and near-shore pipelines. Typically applied over an anti-corrosion layer (such as 3LPE/3PE or FBE), CWC helps the pipeline resist uplift, currents and wave action, while also providing mechanical protection during handling and seabed installation. Octal Pipe can supply CWC pipes as a coordinated package—base pipe + anti-corrosion coating + concrete weight coating—matched to your project’s required coating thickness, density and installation method.
