About U Bolt Coating

Heat Shrink Polyolefin Tube for U-Bolt Coating is suitable for corrosion and mechanical protection between U-Bolts & Pipes.

Pipes running through refineries, chemical plants and offshore platforms are rested on, or secured to, a structural beam support member using U-bolts. Over time the contact area between the un-coated U-bolts and pipe erodes and starts deteriorating the material in the presence of moisture. This excessive corrosion at the pipe support point is the leading cause of process pipe failure and it eventually develops into pinhole leaks.

Features & benefits :

High resistance to impact & abrasion.
Smooth, durable and shrunk over the shank of the U-bolt without any wrinkles, thereby helps reduce the risk of cracking the paint film around the pipe as the bolt is torqued down.
The polyolefin material provides the right combination of hardness and durability to protect the pipe paint but avoids setting up a capillary crevice around the circumference of the pipe.
Has superior jacket tear resistance & elastomeric characteristics allowing better conformance over irregular contours without splitting.
Provides mechanical protection and better abrasion resistance in harsh environments, e.g. tube rubbing against sharp objects or in constant friction
Provides good strain relief.
High shrink ratio (3:1) can help rationalize the stock requirements and also provides a greater application range.
After recovery, it provides an excellent outer cover for protection.
Highly reliable as it is unaffected by heat, ultra-violet rays, vibration, sandblasting or other conditions pertaining to an industrial and marine environment

Market Segment: Electrical, Offshore, Marine, Industrial Oil and Gas Utilities

Exceptional Corrosion Protection

Engineered for harsh environments, our U Bolt coatings provide outstanding protection against rust and corrosion. With up to 500 hours of salt spray resistance, these coatings are perfect for safeguarding U-Bolts used in automobiles, construction, and industrial support. The anti-corrosive layers prolong bolt lifespan, reducing the need for frequent maintenance.

Customizable for Varied Applications

Our U Bolt coatings are highly customizable in terms of size, color, and coating material. Clients can specify dimensions, finishes, and special requirements to ensure products meet unique project demands. This flexibility makes them suitable for securing pipes, beams, rods, and fixtures across a range of industries.

Rigorous Process and Quality Assurance

Each U Bolt undergoes thorough shot blasting and degreasing before coating, ensuring maximum adhesion and durability. We utilize spray, dip, or electrostatic techniques based on end-use requirements, and all coatings comply with RoHS standards. Packaging and storage options further ensure product integrity until installation.

FAQs of U Bolt Coating:

Q: How is the U Bolt coating applied to ensure durability and even coverage?

A: The U Bolt coating process starts with shot blasting and degreasing the surface to enhance adhesion. Coating materials such as epoxy or polyurethane are then applied by spray, dip, or electrostatic methods, resulting in a smooth, even layer with a typical thickness of 60120 microns.

Q: What are the benefits of choosing a smooth, glossy, or matte finish for U Bolt coatings?

A: Choosing among smooth, glossy, or matte finishes allows clients to balance aesthetics with function. Smooth and glossy finishes offer enhanced washability and appearance, while matte provides reduced glare and a subtle look. All finishes retain the coatings protective and anti-corrosive qualities.

Q: When should I opt for a U Bolt with this coating for my application?

A: These coated U Bolts are ideal whenever corrosion resistance and durability are prioritized, especially in outdoor, pipeline, construction, or industrial environments that encounter moisture or harsh weather. The robust coatings effectively extend the U Bolts operational life.

Q: Where are these U Bolt coatings typically used?

A: Our U Bolt coatings are employed in settings such as automotive assembly, construction, industrial support frameworks, and pipeline clamping. They are suitable for a range of environments, from machinery rooms to outdoor infrastructure, thanks to their weather-resistant and anti-corrosive properties.

Q: What customization options are available for U Bolt coatings?

A: Clients can request custom sizes, colors (such as green, black, blue, or more), coating materials, and packaging styles. This adaptability ensures the product meets specific technical and aesthetic requirements for different projects or branding needs.

Q: How do I know if these U Bolt coatings are compatible with my bolts?

A: Our coatings are designed for both mild steel and stainless steel U Bolts, available in standard sizes like M6, M8, M10, M12, or fully customized dimensions. They support manual or machine installation and are suitable for bolts needing anti-corrosive and weather-resistant properties.
