HR D-Pad™
Pipe Anti-Corrosion Protection
Dale Company’s HR D-Pad™ prevents the common pipe corrosion seen from metal-to-metal contact.
What is HR D-Pad™?
The HR D-Pad™ provides a barrier between the pipe and holding structure. Pipe corrosion that results from pipe rack contact can be the byproduct of external factors & varying weather conditions: UV rays, vibration and more. Dale’s HR D-Pad™ is placed between the pipe and the metal structure, giving that added protection from wear and tear on the pipe.
Durable Support for Durable Pipes
What are the Benefits of Anti-Corrosion Pipe Support & Protection Pads?
These support pads are prepped to stand the test of time, regardless of the environment, which reduces the chance for corrosion. We manufacture our anti-corrosion pipe support and protection pads through the process of extrusion rather than molding. This is what makes our HR D-Pad™ more durable over time whereas molded pads tend to crack and become less reliable.
Anti-Corrosion Pipe Support & Protection Pads Benefit Which Industries?
Preventing galvanic corrosion on pipes is a necessity for conducting a successful and productive process for any industry; such as, refineries, chemical plants, mills, offshore rigs and more. We also recommend pairing our HR D-Pad™ with our Pro-Coat U-Bolt™ for additional anti vibration and corrosion prevention. To learn more about the technical properties of our HR D-Pad™ view the HR D-Pad Technical Data Sheet (PDF). Extending the life of your pipes is made easy with simple installation; allowing you to protect all varieties of pipes. Contact us today to learn more.

Ideal Applications
HR D-Pad™ is trusted for anti-corrosion protection in:
- Oil Refineries, Chemical Plants, and Mills – Preserving critical infrastructure from corrosion-related damage.
- Offshore Platforms & Marine Environments – Safeguarding piping in saltwater-exposed areas.
- Structural Piping Supports – Preventing wear in pipelines, racks, and mounted components.
Enhancing Corrosion Resistance
Pairing HR D-Pad™ with Pro-Coat U-Bolts™ provides dual-layer corrosion protection, reducing risks of pitting and galvanic corrosion from uncoated U-bolts. Together, these solutions ensure maximum pipe integrity, longer service life, and reduced maintenance costs.
Reliable, Industry-Tested Performance
Dale Fastener Supply’s commitment to high-performance corrosion solutions guarantees that the HR D-Pad™ delivers proven protection, structural reliability, and ease of use across industries.

HR D-Pad™: Advanced Pipe Protection Against Corrosion & Wear
Dale Fastener Supply’s HR D-Pad™ is an engineered pipe-support solution designed to prevent metal-to-metal contact and significantly reduce corrosion risks in industrial, marine, and offshore environments. Manufactured using a high-performance extrusion process, the HR D-Pad™ provides enhanced durability, vibration resistance, and long-lasting protection for pipeline infrastructure.
How HR D-Pad™ Works
Piping systems are susceptible to corrosion from direct contact with pipe racks, particularly in harsh environments where factors like UV exposure, vibration, and moisture accelerate metal degradation. The HR D-Pad™ acts as a protective barrier, isolating pipes from support structures to prevent wear, surface damage, and crevice corrosion.
What are the benefits of anti-corrosion pipe support & protection pads?
Key Features & Benefits
- Corrosion Prevention – Stops direct metal contact to minimize wear and extend pipe life.
- Extrusion-Molded Durability – Unlike traditional molded pads, our extrusion process ensures crack-resistant, long-term reliability.
- High-Performance Material – Offers chemical resistance, impact toughness, and environmental resilience.
- Vibration Damping – Reduces movement-related stress, lowering the risk of pipe fatigue and failure.
- Easy Installation – Simple, effective, and adaptable for various pipe sizes and configurations.
