Pipeline corrosion is one of the most significant issues that affect the longevity and performance of pipelines worldwide. Whether in industrial applications, municipal water systems, or even in the oil and gas sector, protecting pipes from internal corrosion is crucial for reducing maintenance costs and ensuring operational efficiency. This is where internal pipe sleeves come into play, offering a solution that protects the pipe while maintaining the integrity of the surrounding material.

At Lined Pipe Systems, we specialize in providing cutting-edge pipeline protection technologies, such as our FlexSleeve® and CCB® sleeve systems, designed to combat the challenges of internal corrosion. These systems offer unmatched performance, particularly in the context of pipelines with polymer linings, providing a long-term solution for durability and reliability.

In this blog, we will explore internal pipe sleeves, their role in pipeline protection, and how Lined Pipe Systems’ innovative technologies can provide you with the best solutions for your next project.

What Are Internal Pipe Sleeves?

An internal pipe sleeve serves as a protective insert, typically made from metal, plastic, or other durable materials. Technicians install these sleeves inside pipelines to prevent corrosive substances from directly contacting the pipe’s inner surface, which can degrade the pipe’s performance over time..

Industries that face harsh conditions, such as exposure to water, chemicals, or abrasive slurries, rely on internal pipe sleeves for protection. However, these sleeves act as a barrier, protecting the pipe from corrosion, abrasion, and mechanical damage, ultimately extending the lifespan of the pipeline and reducing maintenance costs.

Why Use Internal Pipe Sleeves?

Internal pipe sleeves serve several critical purposes in pipeline applications:

  • Corrosion Protection: These sleeves protect the interior of the pipe from exposure to corrosive liquids, chemicals, or slurries. This is especially important in industries such as oil and gas, mining, and water treatment, where corrosive substances are commonly transported.

  • Enhancing Pipeline Durability: Over time, pipes can suffer from internal damage due to abrasive materials like slurry, fracking water, or other highly erosive substances. Internal sleeves shield the pipe from such wear and tear, ensuring a longer service life.

  • Improving Flow Efficiency: Internal sleeves can smooth the interior surface of the pipe, reducing friction and improving the flow of materials, thus enhancing the overall efficiency of the pipeline system.

  • Cost-Effective Maintenance: By protecting the pipe from internal damage, these sleeves reduce the need for costly repairs or replacements. Their role in minimizing wear and tear means fewer disruptions and lower maintenance costs in the long run.

The Role of Lined Pipe Systems in Internal Pipe Sleeve Technology

At Lined Pipe Systems, we provide innovative solutions like the FlexSleeve® and CCB® sleeves, which are specifically designed to protect welded joints and pipeline linings from internal corrosion. These technologies have been developed over decades and have proven to be highly effective in numerous applications.

FlexSleeve®: Innovation for Thin Linings

The FlexSleeve® system is one of the most advanced solutions for protecting thin-lined pipelines. Here are some key features of the FlexSleeve® system:

  • Flexibility: The sleeve’s thin-gauge assembly adapts to the shape of the pipe, ensuring an easy insertion process and a consistent seal quality. This flexibility makes it ideal for pipelines that vary in size or shape.

  • Sealing Capability: The FlexSleeve® system features bore seals that accommodate pipe internal diameter (ID) tolerances and can seal at any pipeline pressure. This ensures that the sleeve performs optimally under varying operational conditions.

  • Improved Welding Quality: The sleeve’s flexibility allows for a better fit and smoother welding process, improving root pass quality and ensuring a stronger, more durable seal.

  • Heat Resistance: The design of the FlexSleeve® helps reduce heat impact during welding and does not slow down the process, making it suitable for high-temperature applications.

CCB® Sleeve: Proven Technology for Welded Joints

The CCB® sleeve has been a cornerstone of internal pipe sleeve technology for over 25 years. This patented solution is particularly effective for protecting welded joints in pipelines, especially in diameters 12 inches and smaller. Key advantages of the CCB® sleeve include:

  • 25+ Years of Proven Success: The CCB® sleeve has been successfully used in protecting hundreds of thousands of welded pipe joints, making it a tried-and-tested solution for long-term protection.

  • Tighter Seals: The CCB® sleeve offers a tighter seal than many other systems, ensuring that no corrosive substances penetrate the weld zone, which is often the weakest point in a pipeline.

  • Market Standard for Quality: With its proven performance, the CCB® sleeve has set the market standard for quality in internal pipe sleeve technology.

  • Efficient Design: The CCB® sleeve features a long, sloped profile that allows for pigs to pass through the pipe and reduces head loss, improving the overall flow efficiency.

Applications of Internal Pipe Sleeves in Various Industries

Internal pipe sleeves are used across a wide range of industries where pipelines are exposed to harsh environmental conditions. Some of the key sectors that benefit from these systems include:

Oil and Gas

In the oil and gas industry, highly corrosive substances like produced water, sour oil, and gas expose pipelines to damage.The FlexSleeve® and CCB® sleeve systems provide unparalleled protection against corrosion, ensuring the pipeline remains functional and efficient throughout its life.

Mining and Slurry Transport

In mining operations, pipelines are used to transport abrasive materials such as tailing slurry, coarse ore slurry, and concentrate slurry. Lined Pipe Systems’ SealSleeve™ provides an effective solution for preventing wear and tear in these pipelines, ensuring a longer service life while maintaining efficiency.

Water Treatment and Distribution

Water pipelines, including those used for desalinated water, domestic water, and wastewater, are prone to corrosion from exposure to chemicals and environmental conditions. Internal pipe sleeves protect these pipelines, ensuring that the water transported remains clean and safe. While the pipelines themselves are protected from degradation.

Desalination and Process Water

Desalination projects require pipelines that can withstand harsh conditions, including exposure to seawater and chemicals. Our FlexSleeve® system, along with other advanced internal pipe sleeve technologies, provides superior protection for pipelines in these challenging environments.
