Customer Peace of MindFree advice for correct material selection, surface preparation and coatingapplication criteria, is provided by qualified professionals at either Denso ortheir appointed agents.

Main Advantages of the Denso Tape Coating SystemsDry abrasive blast cleaning to a high quality standard is not essential. Densoclad, Densopol and Denso Butyl tape systems as well as Denso Tapepetrolatum systems are surface tolerant and are suitable for application despite a low quality surface preparation standard.

● Minimum controlled coating thickness as all tapes are factory regulated.

● No delays. Immediate mechanical and corrosion protection is obtained

● Excellent cathodic disbonding resistance

● Tapes can all be applied by hand, hand machine or rolling rig methods.

Denso Tape Wrapping Systems

Introduction Denso’s world-wide reputation as a leading manufacturer and supplier of totally effective pipeline protection systems hasbeen earned by more than 80 years of successful case history performance.A range of products is offered for selection to suit specific project needs involving different soil and backfill conditions,varying surface cleaning standards as well as sub-zero and high temperature application and pipe operating temperatures. For all buried pipeline projects steel surface preparation standards are normally divided into two main categories:

Low Quality - Low quality surface preparation by hand power tools that will require surface tolerant coating systems.

High Quality - Dry abrasive blast cleaning to a high quality near white finish standard.

Densoclad andDensopol SystemsThick pvc backed Densoclad andDensopol bitumen tapes are used inconjunction with a primer and can beapplied with a 55% overlap to achievedouble thickness in one operation.Temperate and Tropical grades areavailable to suit all site conditions.

Denso Butyl SystemsThinner polyethylene backedDenso Butyl Tapes are also used inconjunction with a primer and areparticularly suited for long-lineprojects for very fast automaticmachine application alongside orover the ditch. A separate outerwrapis normally applied at the same time.Standard temperature and hightemperature grades are also available.

Optimum Surface Tolerant Systems

Denso TapePetrolatum SystemsBased on petrolatum, Denso Tapeis suited for all types of pipe and isnormally used in conjunction withDenso Priming Paste. For profilingflanges, couplings, valves and spigotjoints there is a choice of either astandard Densyl Mastic or a lightweight, low density Denso ProfilingMastic. To complete the system, DensoSelf-Adhesive PVC Tape or a Densobitumen tape provides an ideal outerprotective armouring. Denso Tape is also available in a lowtemperature (L.T.) grade and a marinegrade for the protection of jetty piles.
