Product Specification

2.8MM Welded Galvanized Wire Pipeline Reinforced Mesh For Oil And Gas

Welded Galvanized Wire Pipeline Reinforced Mesh  Description:

Welded Galvanized Wire Pipeline Reinforced Mesh is choose high quality hot dipped galvanized wire as material wire. The surface most are choose hot dipped, also special product need cold or electric. Then through our machine professional welded and make in export standard hole size, roll width and length. With strong anti-corrosion and anti-rust properties, so it is durable and has a long service life. It is widely used as reinforcement on concrete weight coating pipelines for oil and gas.Pipeline reinforced mesh is available in three sizes: traditional 10-wire, 8-wire, or 6-wire mesh systems. Pipeline reinforced mesh is primarily used for concrete-coated submarine pipelines. In addition to standard sizes, we also offer other sizes that can be customized to meet customer requirements

Welded Galvanized Wire Pipeline reinforced Mesh Specifications:

Welded Galvanized Wire Pipeline Reinforced Mesh Four Types:

Technical Standards for Welded 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.

Pipeline Reinforced Mesh Applications:

This mesh is first hot-dip galvanized before processing and is mainly used for cement counterweight layers in submarine oil and gas pipelines. Wrapped on the oil pipeline, it plays a role in anti-collision and anti-corrosion protection. It is the preferred product for protecting oil pipelines.
