Bitumen tape HLD T600


Bitumen tape HLD T600 is a high performance anti-corrosive pipe wrapping tape designed for use on buried pipeline, pipe joints, fittings and tie bars where impact or stress is high.


► Easy to apply
► Excellent adhesion
► High strength
► Flexibility
► Resistance to Acid & Alkali
► Excellent impact resistance


Surface preparation
Remove any dirt, oil, grease, rust by suitable methods. Remove any metal burrs or weld spatter. The minimum requirement for surface preparation of pipe/steel surface is by mechanical/power wire brushing to remove any rust scales. Grit blasting can also be done in heavily contaminated areas.

HLD Primer shall be used for priming the steel surface prior to the application of the wrapping tape. Stir the contents of the primer for 1-2 minutes to remove any sediment. Apply the primer at the rate of 4-6m2/L with a brush or roller evenly to ensure complete sealing of all small undulations and imperfections, particularly around weld beats. Reseal the containers when not in use.

Application instructions are for guideline only and are subjected to alterations for specific project requirements. Wrapping should not commence until the primed surface has become touch dry. Apply strips of tape 100mm wide along the weld beads and press firmly. Peel back 150 to 300 mm of the release film and apply the tape, adhesive side, to the pipe. The angle of the tape must be such as to produce the specified overlap. Apply only sufficient tension to ensure good conformation avoiding air pockets and bridging. Ensure end lap area of at least 150 mm when splicing the tapes. Backfill with care.


Surface preparation, priming or wrapping should not take place when the substrate is wet. Do not carry out work when the surface temperature is less than 5°C. All sources of ignition must be extinguished or removed before
carrying out priming operation. Adequate ventilation must also be ensured. Store the tapes at temperatures not exceeding 30°C and avoid excessive load stacking. During the wrapping application, it is important to maintain an even tension whilst controlling the overlap to prevent air entrapment, which could lead to corrosion at a later stage. The tapes are best applied by machine, either hand powered for small runs or mechanically propelled for longer runs. Bitumen tape HLD T600 range of tapes is normally supplied in 10 m lengths. For machine wrapping these lengths can be increased based on special request, to suit the project and reduce the number of roll changes.


Bitumen tape HLD T600 rolls should be stored under cover, out of direct sunlight and protect from extreme temperatures. storage area should be cool, dry, well – ventilated and regularly monitored for temperature and major sources of heat. shelf life is up to 12 month when stored as per recommended storage conditions.


As with all bitumen products caution should always be exercised. Protective clothing such as gloves and goggles should be worn. Treat any splashes to the skin or eyes with fresh water immediately. Should any of the product be accidentally swallowed, do not induce vomiting, but call for medical assistance immediately.
