Subsea pipelines
Concrete-coated pipelines in offshore oil and gas transportation systems.
WENNIAN · PIPELINE REINFORCEMENT
Galvanized low-carbon steel wire, crimped and welded for reinforcement within pipeline concrete weight coating.
01 / THE PRODUCT
Pipeline reinforcement mesh combines crimped line wires with straight cross wires. The welded structure sits within the concrete weight coating, also known as CWC.

A repeating wave profile forms the longitudinal structure of the mesh.
Straight cross wires are resistance welded to the line wires, holding the mesh geometry together.
Low-carbon steel wire with a galvanized finish. Specify the wire and coating requirements for your project.

Final coating and reinforcement selection follows the project's engineering specification.
BEFORE YOUR INQUIRY
Please share the wire diameter, mesh width and spacing, roll length, required quantity, destination and inspection requirements. A drawing is helpful when your specification differs from the reference configuration.
The concrete coating provides the weight. The wire mesh is embedded as reinforcement within that coating. The complete coating arrangement is determined by the project design.
Yes. Select “Drawing-based requirement” in the inquiry form and describe your requirements. Email your drawing to info@wennexa.com and include your inquiry reference if available.
Include the required tests, applicable specification, marking and packing instructions in your inquiry. These details should be agreed as part of the supply specification before an order is placed.
