Non-woven, stitch-bonded, synthetic fabric carrier, fully saturated and coated with a neutral petrolatum compound blended with inert fillers and corrosion inhibitors.
Products are most widely used for anti-corrosion projects.They are simple to apply, highly flexible and conform easily to irregular and voided surfaces.Petrolatum based products can be applied to all kinds of surfaces - cold, wet or submerged, pitted or corroded. Once applied on a minimally prepared surface, corrosion will stop. They have excellent long term UV stability.
These products are corrosion resistant to water, salts, acids and caustics. Petrolatum based products do not harden with the passage of time and can be removed for inspection, then reapplied. Many installations have service lives of over 20 years.
For long-life corrosion protection, sealing and waterproofing of atmospheric buried and submerged metal surfaces. The high degree of conform-ability allows for application over irregular surface profiles including gas utility, sewer, potable water, mining, and wastewater applications.
CN Petro-Tape is stable in composition and plasticity over a wide temperature range. It is non-hardening and non- cracking, which accommodates vibrations and extreme movement of the substrate. CNPetro-Tape is non-toxic, non-flammable with high dielectric strength and highly resistant to mineral acids, alkalis and salts.
Spirally wrapped using a minimum 55% overlap for all applications, For vertical applications the tape shall begin at the bottom and proceed up – providing a“weatherboard” overlap.
May apply longitudinally (i.e., “cigarette wrapped”) when space is too restricted or confined to apply in the preferred spiral manner, with the overlap on the topside of the pipe –providing a "weatherboard" effect.
At the completion of each roll, smooth the overlaps by hand. Maintain a 100mm overlap when overlapping one roll with the end of a new roll.
