Denso Petrolatum, Bitumen & Butyl Tapes & Protal Liquid Coatings
Long-term Corrosion Protection for Buried Steel Pipelines, Fittings & Specials.
1/3
Description
- 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.
Main Advantages of the Denso Tape Coating Systems
- Dry abrasive blast cleaning to a high quality standard is not essential. Densoclad, Densopol and Denso Butyl tape systems as well as Denso Tape petrolatum 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 Petrolatum Systems
- Based on petrolatum, Denso Tape is suited for all types of pipe and is normally used in conjunction with Denso Priming Paste. For profiling flanges, couplings, valves and spigot joints there is a choice of either a standard Densyl Mastic or a light weight, low density Denso Profiling Mastic. To complete the system, Denso Self-Adhesive PVC Tape or a Denso bitumen tape provides an ideal outer protective armouring.
Denso Tape is also available in a low temperature (L.T.) grade and a marine grade for the protection of jetty piles.
Denso Tape Wrapping Machinery
- A comprehensive range of tape wrapping machines are available to enable fast and consistant high quality application. Use of the machines ensures consistant tension and accurate overlap of the tape at all times. Main features are:
Hand powered as well as powered rolling rig versions available
Consistent tape tension always achieved
Accurate tape overlap always achieved
Automatic removal and gathering of tape interleaving
Fast application
Denso Protal Pipeline Coatings
- A range of epoxy coatings designed for application to abrasive blast cleaned steel pipe, welds, tie-ins, fittings etc.
High build achieved in only one coating operation
Very fast curing liquid applied coatings
Designed for the external protection of all line-pipe, fittings, specials and storage vessels
Excellent cathodic disbonding resistance
Standard high quality abrasive blast cleaning surface preparation
Can be applied by either brush, roller or spray methods
Protal Repair Cartridge Kits with a dispensing gun are available in all Protal grades. Economical with minimal wastage - very quick and easy to apply
