Frequently Asked Questions
Q
What surfaces can viscoelastic tape be applied to without primer?
Viscoelastic tape can be directly applied to steel, PE, PP, and FBE coated surfaces without requiring any primer, simplifying the surface preparation process significantly.
Q
What is the operating temperature range of the viscoelastic tape?
The viscoelastic tape is designed to perform reliably across a wide temperature range of -30℃ to 95℃, making it suitable for diverse climate conditions and pipeline environments.
Q
What pipeline coating systems is this viscoelastic tape compatible with?
The tape is well-matched with 3LPE/PP coating, FBE coating, CTE coating, and asphalt materials, providing broad compatibility with commonly used pipeline protection systems.
Q
What are the typical applications of viscoelastic tape?
It is primarily used for field joint anticorrosion of pipelines, repair of damaged coatings, and protection of irregular fittings such as elbows, bends, T-joints, and insulated flanges.
Q
What standard dimensions does the viscoelastic tape come in?
The tape is available in thicknesses of 1.8mm or 2.0mm, with a standard width of 100mm and a roll length of 10 meters. Custom dimensions can also be provided based on specific project requirements.
Q
How does the viscoelastic tape protect against corrosion?
The tape provides excellent barrier performance through its viscoelastic compound, which strongly blocks water and oxygen penetration. It also demonstrates outstanding cathodic disbondment resistance (0 mm at both 23°C and 95°C after 28 days) and high electrical insulation resistance (1.0×10¹⁰ Ω·m²), ensuring comprehensive corrosion protection.
