Twisted Woven Hexagonal Hole Wire Mesh Low Carbon Steel

Twisted Woven Hexagonal Wire Mesh

Twisted Woven Hexagonal Wire Mesh Description:

Type TW Twisted Hexagonal Wire Mesh (for Pipeline Coating/Counterweight Coating)This wire mesh is primarily used in concrete weight coatings (CWC) for marine pipelines, serving to reinforce and prevent cracking.

Type TW Twisted Hexagonal Wire Mesh is a metal wire mesh manufactured using a special weaving process, specifically designed for concrete coatings in oil, gas, and water pipelines. Its unique hexagonal hole structure effectively enhances the tensile strength of the concrete layer, preventing the coating from cracking or peeling off due to stress or impact during transportation, hoisting, and subsea laying.

Type TW Twisted Hexagonal Mesh Specifications:

According to international standards (such as the ASTM system), the typical specifications of Type TW are shown in the table below:

Parameter Item : Typical Range  Remarks

Material : Low Carbon Steel  Complies with ASTM A641 or equivalent

Hole Shape : Hexagonal  Braided (twice-twisted/triple-twisted)

Hole Size : 38mm Most common size  Other options 20mm,25mm

Wire Diameter : 1.0 mm to 1.6 mm  Customizable according to customer coating thickness

Width:190 mm, 210 mm, or 241 mm  Larger diameter pipes are available in wider specifications, such as 300 mm.

Length: Commonly 100m- 500m.

Tensile strength: 350-550 MPa, ensuring excellent ductility.

Surface treatment: bright or galvanized, depending on corrosion protection requirements.

Type TW Twisted Hexagonal Mesh Advantages:

1.High Flexibility: The Type TW structure allows the wire mesh to fit tightly to steel pipes of various diameters.

2.Excellent Grip: Hexagonal pores allow for full concrete penetration, forming a strong mechanical anchor and preventing "shell-meat separation."

3.Edge Reinforcement: Typically includes reinforcing edge wires to prevent tearing during high-speed winding.

4.Construction Compatibility: Suitable for horizontal spraying or compression coating processes.

Type TW Twisted Hexagonal Mesh Applications:

1.CWC (Contains Weighted Marine Pipeline): Provides negative buoyancy and mechanical protection for subsea pipelines.

2.Corrosion Protection Layer Reinforcement: Provides physical support over asphalt or epoxy coatings.

3.Rock Shield: Additional protection for buried pipelines in rocky areas.

 Packaging and Storage:

Packaging: Typically supplied in large rolls (500m-1000m in length) to minimize roll changeover time during construction.

Storage: Store in a dry, well-ventilated place, avoiding direct contact with the ground. For non-galvanized (smooth) wire mesh, it is recommended to use within 3 months to prevent severe corrosion affecting adhesion.
