ASTM A810-01 ASTM A810-01 Pipeline Reinforced Mesh – Pipe-line Reinforced Welded Wire Mesh

Pipeline reinforced mesh is also called concrete weight coating mesh (CWC mesh). The material of the mesh is low carbon steel with galvanized coating. It can either be cold galvanized wire or hot dipped galvanized wire meeting to ASTM and the line wires are deeply crimped and then welded to form a wave structure, making it easy to be coated with concrete and then submerged in water or earth. It has excellent corrosion and rust resistant performance, preventing concrete weight coated pipeline from being damaged during installation and after it is in place.

Structures

Pipeline reinforced mesh is made of line wires and cross wires.

• Line Wire. They are deeply crimped and then spaced at equal distances to be welded into a wavy structure. Pipeline reinforced mesh is available in various types, with 6/8/10 cross wires per pipeline reinforced mesh. For a pipeline reinforced mesh with 6 cross wires, the middle 4 cross wires are equally spaced and the two cross wires at the edge are farther away from the adjacent cross wires. The wavy structure makes it easy for the pipeline reinforced mesh to be coated with concrete and then immersed in water or soil.
• Cross Wire. They are straight in shape, and the cross wires on the same pipeline reinforced mesh are spaced at the same distance. After spot welding technology, they are well fixed with the wavy line wires
• Exposed Wire Edge: ≤ 2.5 mm
  The pipeline reinforced meshes have excellent corrosion and rust resistant performance to prevent damage to the pipeline.

Specifications of pipeline reinforced mesh

4 types pipeline reinforced mesh: HN-N, HN-T, HN-L and HN-W.

HN-N
It is a low carbon steel wire for the reinforcement of concrete weight coated pipelines. The mesh includes 6 line wires that are deeply crimped between the cross wires. The 2-inch mesh with both sides between the line wires is intended for coating with an overlap of 1 inch.
