Width 190.5 MM Concrete Weight Coating Mesh In Rolls Hot Dip Galvanized Wire

Width 190.5 MM Galvanized Offshore Pipeline Counterweight Welded Wire Mesh

Galvanized Offshore Pipeline Counterweight Welded Wire Mesh Description:

Pipeline Counterweight Welded Wire Mesh also known as pipeline reinforcement mesh, pipeline mesh, marine reinforcement mesh, etc., is a welded mesh commonly used for the reinforcement of concrete counterweight coated pipelines. Marine reinforcement mesh is a popular product in the world industry and is used for concrete counterweight coating of offshore oil and gas pipelines. Marine reinforcement mesh is suitable for compression and impact coating processes. The diameter wires are deeply curled to facilitate the application of concrete coating. The material used is galvanized mild steel. It can be cold-dip galvanized iron wire or hot-dip galvanized wire deeply curled to facilitate application in concrete. Three specifications of marine reinforcement mesh are available with traditional 10 wire, 8 wire or 6 wire mesh systems. Pipeline reinforcement mesh is mainly used for concrete counterweight coating of submarine pipelines. In addition to conventional specifications, we also supply other specifications that can be customized according to customer requirements

Technical Standards for Galvanized Offshore Pipeline Counterweight Welded Wire 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.
