To protect pipelines in high temperatures, Denso offers the Hotline Tape system.
Pipelines always require long-term protection from corrosion. Denso North America specializes in products that stop pipes from corroding, even in extreme temperatures. For high temperatures, the company offers the Denso Hotline Tape system – featuring a special Hotline petrolatum tape, with assistance from Denso Paste HT and Densyl Mastic. This system is perfect for pipework that is above or below ground, under pipe insulation, or lain in concrete.
Easy application in all temperatures
Denso Hotline Tape is composed of a synthetic fabric impregnated with a mix of high-temp petrolatum, mineral fillers, and thermal extenders. It is also backed with a thin, high-density polyethylene film for added protection. Hotline Tape can provide corrosion protection for pipes, flanges, valves, and related surfaces, with a surface temperature of up to 110 degrees Celsius for applications above ground, or up to 83 degrees Celsius below ground.
Other major features of Denso Hotline Tape:
The first step in applying this Denso tape system is to prepare surfaces by removing all loose scale, rust, and other foreign matter. A high-pressure water wash from 3,000 to 7,000 pounds per square inch or wire brushing to an SP2 surface are acceptable methods. Secondly, apply a thin layer of Denso Paste HT to the prepared surface. Next, begin to spirally wrap the tape with a minimum overlap of 25 millimetres or with a 55 per cent overlap in extremely corrosive conditions.
During the tape-wrapping phase, press all air pockets out and smooth all the lap seams, while ensuring that the overlap between tape rolls is enough to provide constant protection wherever rolls must be joined. It is wise to use an approved outerwrap in below-ground applications. For irregular surfaces like valves and flanges, Densyl Mastic or Denso Profiling Mastic may be necessary.
With the unique Denso Hotline Tape system, pipelines stay protected in high temperatures for years.
