RANSPIPE-CBT 2MM is an Anti-Corrosive tape based on Coal Tar/ Bitumen and specifically designed to comply with the requirements of IS: 10221-1982. It incorporates a centre core of 45 gsm/sqm of Fibre Glass Tissue and HMHDPE film of which lends mechanical strength, dimensional stability to the product. These centre cores are laminated with 3 layers of coal tar or bitumen mix. The final product has a top and bottom layer of thermo fusible HMHDPE Film. All the seven layers are calendared together to create this revolutionary 2mm thick tape. The material conforms to IS: 15337-2003 and AWWA: C203-2008.
Properties-
Excellent resistance to positive water & vapor pressure. Good heat resistance. Moisture Resistance. Good dimensional stability under tension. High puncture and fatigue resistance. High tensile and tear strengths. Corrosion Prevention.
INSTRUCTIONS FOR USE
The application temperature should be between 5°C to 45°C. Application procedures may vary slightly depending upon site conditions. The general recommended guidelines for the application of the waterproofing system are as follows: SURFACE PREPARATION The surface shall be cleaned thoroughly of all contaminants like dust, traces of curing compound, oil and grease. All surface imperfections and protrusions shall be removed and repaired. PRIMING Apply Solvent based RANSBITU-PRIMER @ 0.3-0.4L /Sqmt as per ASTM D 41 & IS: 3384-1986 and BS 4147- 1980 to a clean smooth and dry surface by brush, roller or spray. Allow the primer to dry prior to the application of the membrane. As the viscosity of the primer is low, it easily creates adhesion between the membrane and the pipe surface. In addition to that the primer also acts as a binder for the dust which gets accumulated on the pipe surface even after cleaning. ALIGNMENT & TORCHING After RANSBITU-PRIMER, next step is followed; RANSPIPE-CBT 2MM Pipe Wrap Coating is then wrapped around the pipe in spiral fashion and bonded to pipe by thermo fusion process using LPG Torch. An overlap of 10mm is to be allowed. The overlaps are to be sealed by thermo fusion process. A second coat of primer is applied over the first layer of RANSPIPE-CBT 2MM and allowed to dry till it becomes tacky. RANSPIPE-CBT 2MM second layer is spirally wound over the first layer in spiral fashion and the overlaps are thermo fused. An area of 250 mm at the end of the Pipes is to be left uncoated to permit installation and welding. This area is to be coated after welding. CAUTION Do not over torch the membrane as this will expose the reinforcement and cause damage to it. SEALING Heat both the overlaps and use round tipped trowel to seal the overlap. Adequate heat is confirmed when a uniform flow of melted bitumen compound flows evenly in a bead that oozes from the applied membrane’s edges. Excess compound should be smoothened and pressed into the seam using a heated trowel. Any un-bonded areas must be lifted and re-torched. Do not attempt to reseal by torching the top surface of the membrane. Up stand.
