Protective pipeline mesh by Denso offers protection for anti-corrosion coatings

Denso Rock Shield is easy to apply to pipelines.

Denso North America is the perfect source for industrial tools that prevent corrosion, particularly for pipeline builders and maintenance workers. Aside from the company’s renowned selection of high-quality anti-corrosion tapes and liquid coatings, it offers Denso Rock Shield, a special protective pipeline mesh designed to protect anti-corrosion coatings from rocky backfill.

Due to its lightweight material, the Denso Rock Shield solution has the ability to handle challenging weather and environmental conditions.

Compressive strength and flexibility

This protective pipeline mesh is a flexible padding made out of high-density polyethylene, which incorporates a special expansion process that offers compressive strength and flexibility. Environmentally stable and available in a wide variety of sizes, Denso Rock Shield can be cut with a utility knife. This unique product comes in both Standard- and Heavy-Duty versions; the latter one is perfect for pipelines that run through areas with rocky terrain. Both of them are extruded into a diamond mesh pattern.

Rock Shield offers many key advantages and features to users. Among the examples:

• absorption of the impact of uneven backfill;
• cost-efficiency;
• cushioning against concrete weights;
• simple installation;
• flexibility for easy handling, even in very low temperatures;
• high impact and tensile strength;
• minimal abrasion of coating from underground pipe movement;
• porous mesh that enables water flow for cathodic protection and testing, without any inhibition of the cathodic flow;
• protection of coating from protruding rocks in the trench;
• protection of piping during future excavations; and
• resistance to temperature extremes and wet weather.

This protective pipeline mesh can be applied in a simple way. For pipelines with diameters of no more than 450 millimetres (mm), users should unroll the material parallel to the pipe and then wrap it around the pipeline in a longitudinal fashion. The next step is to fasten it with tape, buckles, or cable ties. If the diameter is larger than 450 mm, the user should pre-cut the sheets to match the pipe circumference and then wrap them around the pipe in a spiral fashion before fastening it.

Trust Rock Shield for cost-effective, durable, lightweight, solid protection.
