China China Suppliers Factory Heat Shrinkable Fiberglass Reinforced Sleeve for HDD Corrosion Protection Manufacturer, Suppliers

Introducing FRDK, a high-performance fiberglass reinforced heat shrinkable sleeve specifically engineered for girth weld corrosion protection in pipes utilized for directional drilling applications. Manufactured in China, our FRDP 60C heat shrinkable sleeve (HSS) comes with a separate closure patch and is tailored to provide effective corrosion protection for pipelines operating at temperatures up to 60℃. Once installed, this heat shrink sleeve securely bonds to steel substrates and commonly used mainline pipe coatings such as FBE, polyethylene, and thermal insulated pipelines.

FRDP heat shrinkable sleeve HSS excels at bonding with steel substrates, FBE primer, and plant-applied polyethylene coatings to create a continuous, durable corrosion protection system for pipelines. As a trusted supplier and factory, we are committed to delivering quality products that exceed industry standards, ensuring the longevity and reliability of your pipeline systems.

Product Description

Product Introduction

Construction: three-layer system.
First layer: liquid epoxy, solvent-free, two-component.
Second layer: high shear strength hot-melt adhesive.
Third layer: radiation cross-linked, high density polyethylene, fiber reinforced composite structure.
Additional component: Wear Cone as extra protection against pull-through forces, of the same construction as the main sleeve.

The FRDK heat shrinkable fiberglass reinforced sleeves provides effective protection against abrasion and wear forces that occur during the pull-through operation. The system is fully compatible with cathodic protection systems, resists cathodic disbandment and is designed for a wide range of operating temperatures.

Frequently Asked Questions

What is the FRDK heat shrinkable fiberglass reinforced sleeve used for?

The FRDK sleeve is designed to provide effective protection against abrasion and wear forces during horizontal directional drilling (HDD) operations for oil & gas pipelines, water pipelines, and other underground installations.

What are the main layers of the FRDK sleeve construction?

The FRDK sleeve features a three-layer system: a liquid epoxy first layer (solvent-free, two-component), a high shear strength hot-melt adhesive second layer, and a radiation cross-linked high-density polyethylene fiber reinforced composite structure as the third layer.

Is the FRDK sleeve compatible with cathodic protection systems?

Yes, the FRDK sleeve is fully compatible with cathodic protection systems and demonstrates superior cathodic disbondment resistance, making it ideal for long-term pipeline protection.

What types of pipeline coatings are compatible with FRDK sleeves?

FRDK sleeves are compatible with PE (Polyethylene), FBE (Fusion Bonded Epoxy), and Coal Tar pipeline coatings, providing versatile application options for various pipeline protection systems.

What is the purpose of the Wear Cone component?

The Wear Cone serves as an additional protective component against pull-through forces during HDD operations. It has the same construction as the main sleeve and provides extra protection at critical stress points.

What are the temperature requirements for FRDK sleeve installation?

The FRDK sleeve requires preheating for proper installation. It is designed to operate across a wide range of temperatures and demonstrates excellent performance at both ambient (23°C) and elevated temperatures (65°C) as shown in the technical data.
