Outer diameter of pipeline, mm Wall thickness of pipe, mm Isolation thickness of ACC¹, mm Water density including impurities, kg/m³ Concrete density, kg/  m³ Concrete coating thickness, mm Polyurethane coating thickness, mm Pipeline section type flood land channel dam pond offshore

Weight of 1 linear meter of concrete coated pipe, kg Diameter of CWC²pipe, mm Negative buoyancy coefficient³

1. “ACC” – Anticorrosion coating
2. “CWC” – Concrete weight coating.
3. Calculation is done without considering sections having no CWC

Calculation is done according to the following reference documents: Code of Practice 36.13330.2012 Main Pipelines. Revised edition SNiP 2.05.06-85*, Code of Practice 107-34-96 Ballasting, Stabilization of Gas Pipeline Positioning at Design Reference Marks, TU 1394-001-22390022-2015 Pipes with External Concrete Weight Coating.
