Non-woven Petrolatum tape
Description
Non-woven petrolatum tape is made of stitch-bonded synthetic fabric carrier,
and coated with a neutral petrolatum compound blended with inert fillers and corrosion inhibitors.
This petrolatum tape designed for corrosion protection of buried or exposed or marine pipes rods, cables, valves and metal fittings, tanks.
it also be called grease tape, samilar to PETRO tape.
| Designed for | marine pipes rods, cables, valves and metal fittings, tanks. |
| samilar to | dens tape. |
| Materials | Non-woven, stitch-bonded, synthetic fabric carrier |
Uses
Application over irregular surface profiles including gas utility, sewer, potable water, mining,
For long-life corrosion protection
Sealing and waterproofing of buried and submerged metal surfaces
Use for wastewater applications.
Characteristics
The high degree of conformability
Non-toxic, non-flammable with high dielectric strength
Highly resistant to mineral acids, alkalis and salts.
Application
Spirally wrapped 55% overlap for all applications,
For vertical applications the tape shall 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.
