Simple Product Description
Visco-Elastic Tape is a wraparound corrosion protective coating consisting of a modified and reinforced visco-elastic adhesive applied onto a polyethylene carrier film.
Visco-elastic can be used for the coating of pipes, coating of risers, coating of flanges, coating of manholes, coating of valves, coating of offshore risers and pillars, underwater coating of risers, coating of welded sockets, repair of all type of coatings, sealing of pipe and cable conduits, sealing of tank chimes, sealing of pipe casings.
Product Features
Saves time, surface preparation no need blasting and preheating, without applying epoxy primer
Super bonding to Steel, and any coating material include PE, PP, FBE and AE
Superior cathodic disbondment offers the optimum barrier long term protection against corrosion.
Self-healing ability when slightly damaged due to plastic-elastic properties
No flowing and dripping on maximum operation temperature
Impermeable to water and oxygen
Long shelf-life

1. Surface treatment The surface rust of pipe body is removed by mechanical rust removal equipment (electric angle mill), and the derusting grade reaches ST2. After rust removal, the surface of the pipe body is dried by a heat blower. 2. Pipe body wrapped with viscoelastic anti-corrosion tape Wrap a layer of viscoelastic anti-corrosion tape around the pipe section which has finished surface treatment, and the lap length between the end and the original coating shall not be less than 50mm. The minimum lap length of the joint of anti-corrosion tape is 10 mm. When wrapping the viscoelastic anti-corrosion tape, it is unnecessary to maintain a large tension, and press the edge and overlapping part of the tape by hand. 3. Flange and other special-shaped parts wrapped with viscoelastic anti-corrosion tape For the anti-corrosion operation at the connection of valve flange, the connecting bolt can be filled with anti-corrosion paste and coated with viscoelastic anti-corrosion tape. 4. Wrapping outer protective tape The basic operation method is the same as that of viscoelastic anti-corrosion tape, but the tension shall be maintained when wrapping the outer protective tape. The overlapping amount of joint part is 50%. The two ends of the anticorrosive pipe section shall be exposed 1-2mm respectively, and the outer protective tape shall not be wrapped. 5. Quality inspection The quality requirements for installation of viscoelastic anti-corrosion tape and outer protective tape: the surface is flat, overlapping is even, and there is no bubble, wrinkle and damage. |
