Pipeline Reinforced Mesh Main Production Parameters

Pipeline Reinforced Mesh Main Production Parameters

(I) Material

1. Base Material: Mild steel is generally used as the base material for the mesh. Mild steel has excellent machinability and can be manufactured into steel wires of varying specifications through a variety of processes to meet production needs. Its relatively low cost effectively controls production costs while ensuring product performance, making it more economical for large-scale pipeline projects. It also possesses sufficient strength and toughness to provide basic support and protection for pipelines.

2. Surface Treatment: Galvanizing is commonly used, including cold-dip galvanizing and hot-dip galvanizing. The galvanizing layer forms a dense protective film on the mild steel surface, effectively isolating it from corrosive media such as air and moisture, significantly improving the mesh's corrosion resistance and rust resistance, and extending its service life. Hot-dip galvanizing provides a relatively thicker layer and better protection, making it suitable for pipeline projects with more severe corrosive environments. Cold-dip galvanizing offers lower costs and provides good protection even in less corrosive environments.

(II) Structural Parameters

1. Wires: These are wavy in shape, first deeply crimped, then evenly spaced, and welded into a wavy structure. This unique wavy structure increases the contact area and friction with the concrete, allowing the mesh to tightly bond with the concrete after wrapping, significantly enhancing the stability and strength of the overall structure. When subjected to external impact or pressure, the wavy structure effectively disperses stress, preventing localized stress concentration and structural damage. Different types of pipeline reinforced mesh have varying wire counts, with 6, 8, and 10 being the most common. For example, the HN-N type contains 6 wires, deeply crimped between the cross wires; the HN-T type has 8 wires.

2. Cross wires: These are straight in shape, with equal spacing between cross wires within the same pipeline reinforcement mesh. Spot welding secures the cross wires to the wavy wires, forming a stable mesh structure. This ensures the mesh possesses strength and stability in all directions, effectively preventing relative displacement between the wires and guaranteeing effective pipeline reinforcement.

(III) Size Parameters

1. Wire Diameter: Depending on the application scenario and project requirements, wire and cross wire diameters vary. Common wire diameters fall within a certain range, such as the 2.0mm wire diameter pipe reinforcement mesh shown in the video. Wire diameter directly affects the mesh's strength and load-bearing capacity. Thicker wire diameters can withstand greater forces and are suitable for large pipelines or harsh working conditions with higher strength requirements. Finer wire diameters are suitable for small pipelines or projects with strict cost control and lower strength requirements.

2. Mesh Size: Mesh size options are also available, and different types of pipeline reinforced mesh have different mesh sizes. For example, the 2-inch mesh size of the HN-N type ensures structural strength while facilitating uniform concrete filling, enhancing bonding with the concrete and ultimately improving pipe protection. A reasonable mesh size ensures sufficient concrete flow while preventing localized voids or loose concrete during pouring due to overly large mesh sizes.
