25.4×67 mm Opening Pipeline Concrete Reinforcing Mesh

25.4×67 mm Opening Pipeline Concrete Reinforcing 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.

Technical Standards for 25.4×67 mm Opening Pipeline Concrete Reinforcing 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.
