Proper pipe sealing is crucial in industrial and construction projects. Oily raw material tape, known for its excellent sealing performance and ease of use, is a top choice for various applications. This article explores the preloading technology of oily raw material tape, offering a step-by-step guide, sealing performance tests, and practical solutions to common problems, ensuring leak-proof results for diverse scenarios.
1. What is Oily Raw Material Tape?
Oily raw material tape is a sealing tape coated with a unique oil-based material, enhancing adhesion and durability in demanding environments. This makes it superior to standard raw material tapes.
Key Features and Benefits
- Exceptional Sealing Performance: The oil coating fills micro gaps, ensuring no leaks.
- Corrosion and Temperature Resistance: Suitable for high-pressure and high-temperature environments.
- Ease of Installation: Flexible material adapts to complex joints and irregular surfaces.
Common Applications:
- Building plumbing systems: Hot and cold water pipes, drainage systems.
- Gas pipe connections: High-pressure and secure sealing for gas pipelines.
- Industrial equipment: High-pressure or chemically exposed pipes in industrial plants.
By addressing critical sealing challenges, oily raw material tape has become indispensable in both industrial and household applications.
2. Why is Preloading Technology Important?
Preloading technology refers to applying controlled tension to the tape during installation. This ensures a tighter seal, reduces the risk of leaks, and enhances durability.
Key Benefits of Preloading Technology
- Enhanced Sealing Strength: Ensures a stronger bond between the tape and the pipe surface.
- Minimized Loosening: Prevents failures caused by thermal expansion, contraction, or vibration.
- Optimized Installation Quality: Reduces errors and ensures consistency in sealing.
By integrating preloading during installation, the tape delivers reliable performance even in high-stress environments.
3. Preparation and Installation Process
3.1 Cutting and Splicing Techniques
Proper cutting and splicing ensure seamless application and optimal sealing performance:
- Cutting Dimensions: Cut the tape slightly larger than the design requirements (add 2–5 mm to each side) to prevent slippage.
- Extra Length Allowance: Leave an additional 20–40 mm at both ends to allow for tension adjustments during wrapping.
- Splicing Methods:
- Flat Joint: For basic sealing needs.
- V-Shaped or Beveled Joint: Distributes stress more evenly, improving sealing reliability.
- Layered Splicing: Ideal for scenarios requiring enhanced sealing with multiple layers.
3.2 Step-by-Step Installation
- Clean the Pipe Surface: Remove dust and grease to ensure strong adhesion.
- Wrap the Tape: Wind the tape evenly along the pipe thread direction, ensuring no gaps or overlaps.
- Apply Tension: Gently pull the tape during wrapping to ensure it adheres tightly to the pipe surface.
- Tighten the Connection: Secure the pipe joint with tools, avoiding excessive force that could damage the tape.
These steps, when performed correctly, maximize the tape’s sealing efficiency and longevity.
4. Testing the Sealing Performance
Key Testing Methods
- Tissue Paper Test: Place dry tissue around the joint and check after a few minutes for moisture. If the tissue remains dry, the seal is effective.
- Pressure Testing: Apply water or air pressure to detect leaks.
- Visual Inspection: Look for water droplets or oil seepage around the connection point.
If any issues are detected, reapply or adjust the tape for optimal performance.
5. Common Issues and Solutions
Properly addressing common problems with oily raw material tape ensures long-term sealing performance:
5.1 Why is the Seal Ineffective?
- Cause: Uneven wrapping or insufficient tension during application.
- Solution: Reapply the tape with even tension and ensure full coverage of the pipe threads.
5.2 What Causes Leaks at Splice Points?
- Cause: Improper splicing or gaps between tape sections.
- Solution: Use V-shaped or beveled splicing techniques to create a seamless connection.
5.3 How to Prevent Failure in High-Temperature Conditions?
- Cause: Standard tape degrades under high heat.
- Solution: Use high-temperature-resistant oily raw material tape for such environments.
5.4 How to Verify Tape Quality?
- Inspection Tips: Check for a smooth, undamaged surface and consistent oil coating. Stretch the tape lightly to test its flexibility and tensile strength.
By addressing these issues proactively, you can maintain a secure and durable seal for any application.
