Pipe Guard Wave Mesh Pipeline Reinforced Mesh

Product Specification

Pipe Guard Wave Mesh Pipeline Reinforced Mesh 

Pipeline Reinforced Mesh Description:

Offshore pipeline counterweight welded wire mesh, also known as concrete weight coated mesh, is a specialized welded wire mesh made from low carbon steel wires. The line wires are deeply crimped and then welded into a corrugated structure, allowing for easy application of concrete coating, after which the mesh can be embedded underwater or underground. This product is primarily used for reinforcing, weighting, and protecting subsea oil and gas pipelines. It effectively resists corrosion and pressure in marine environments, thereby extending pipeline lifespan.

Pipeline Reinforced Mesh Specifications:

Pipeline Reinforced Mesh Good Advances:

1.     High tensile strength: Manufactured from high-strength steel wires, it withstands the stress and pressure during pipeline construction, ensuring pipeline stability and durability.

2.     Corrosion and rust prevention: Following galvanization, the welded wire mesh exhibits excellent corrosion and rust prevention properties, effectively mitigating corrosion and damage to subsea pipelines.

3.     Significant structural reinforcement effect: The corrugated structure provides superior concrete adhesion enhancing the pipeline’s structural integrity and preventing issues such as cracks or leaks caused by external forces.

4.     Easy to install:  This welded wire mesh features a simple design and is easy to install, quicky providing reinforcement and protection for pipelines, thereby saving construction time and costs.

5.     High cost-effectiveness. Compared to traditional pipeline reinforcement methods (such as concrete or rebar reinforcement), offshore pipeline counterweight welded wire mesh offers a more cost-effective solution suitable for long-term use.

6.     Strong weatherability. The product can withstand harsh marine environments, including extreme temperatures and severe weather, ensuring the long-term stable operation of pipelines.

7.     Neat appearance: The welded wire mesh has a neat and regular appearance with secure weld points, facilitating  transportation and stacking, and maintaining a god appearance after installation.

Pipeline Reinforced Mesh Application:

1.Water and wastewater pipelines

2.Chemical processing pipelines

3.River bottom gas & oil pipelines

4.Everglades gas pipelines

5.Subsea gas & oil pipelines

Technical Standards for Galvanized Wire Pipeline Reinforced Mesh :

1. Wire Mesh Structural Requirements

The wire mesh should be RSFM type or similar. The wire mesh is made of longitudinal and transverse wires welded together using resistance welding.

2. Reference Standards

Welding of the wire mesh must comply with ASTM A185 and the wire mesh must meet ASTM A82.

3. General Requirements for Wire Mesh

The wire should be made of low-carbon steel wire rod, and the surface of the wire mesh should be galvanized for corrosion protection.

4. Wire Diameter Requirements

The wire mesh diameter must be no less than 2.55 mm x 2.0 mm (longitudinal wire x transverse wire), and 25.4 mm x 67 mm (longitudinal wire x transverse wire).

(Note: The wire mesh manufacturer guarantees that the wire mesh provided will withstand pipes with a diameter of 813 mm, a minimum 4.2 mm 3LPE anti-corrosion coating, and a 110 mm thick concrete weight coating. Using three layers of wire mesh, the minimum ratio of the average circumferential cross-sectional area of the reinforcement to the concrete layer cross-sectional area is 0.5%. The minimum ratio of the longitudinal cross-sectional area of the reinforcement to the concrete layer cross-sectional area is 0.08%.)

5. Mechanical Properties of Steel Wire

The mechanical properties of steel wire must comply with the requirements of GB/T 343. Tensile strength of wire ≥ 485 N/mm², elongation ≥ 12%, testing method GB/T 228. Shear strength of wire mesh welds ≥ 241 N/mm², testing method GB/T 1499.3. 180° bends ≥ 4 times, testing method GB/T 238.
