Conquer Corrosion at the Weld Zones with FlexSleeve®
The vast network of pipelines that crisscrosses the globe plays a vital role in our daily lives, transporting essential resources like oil, gas, and water. Ensuring the integrity of these pipelines is paramount, as leaks and ruptures can have devastating consequences for the environment and public safety.
One of the biggest threats to pipeline integrity is corrosion, which can weaken the pipe walls and lead to catastrophic failures. For internally coated carbon steel pipelines, a particularly vulnerable spot exists at the weld zones. These areas, where individual pipe segments are joined together, lack the protective coating applied to the rest of the pipeline.
Traditionally, protecting these bare steel weld zones has been a significant bottleneck in pipeline construction. The two main methods – manual and robotic patching – are slow, labor-intensive, and introduce delays that can stretch into months. This blog post dives deep into the challenges of protecting pipeline weld zones from corrosion, explores the limitations of existing solutions, and introduces FlexSleeve® by Lined Pipe Systems (LPS) – a revolutionary technology that streamlines construction and ensures flawless internal corrosion protection.
Corrosion in Pipelines and Weld Zone
Corrosion is the deterioration of a material due to its interaction with its environment. In pipelines, this interaction primarily involves the steel reacting with elements like oxygen, water, and the substances being transported. Over time, this reaction can eat away at the pipe wall, reducing its thickness and increasing the risk of leaks and ruptures.
The presence of an internal coating significantly slows down the corrosion process for the majority of the pipeline. However, the weld zones remain exposed bare steel, creating a prime target for corrosion to take hold. Left unprotected, these areas can become weak points, jeopardizing the entire pipeline’s integrity.

Traditional Methods for Protecting Weld Zones
There are two primary approaches for protecting the internal weld zone on coated carbon steel pipelines:
Manual Patching
This method involves crews physically entering the pipeline after welding is complete. Once inside, they painstakingly clean, blast, and apply a protective coating to the interior weld zone. This process is slow, labor-intensive, and prone to human error. Additionally, safety concerns arise due to the confined space environment within the pipeline. Realistically, only a few joints can be completed per day using this method, significantly slowing down construction progress.
Robotic Patching
This method utilizes robots specifically designed to clean, coat, and inspect each weld zone. While offering a slight improvement in speed compared to manual patching, robotic systems still lag behind the mainline welding process. This creates a gap between crews, leading to delays as the robotic patching struggles to keep pace.
Both manual and robotic patching methods share a key drawback: they significantly extend the construction timeline. Months of unnecessary delays can be added to projects, impacting budgets and overall project efficiency.

What is FlexSleeve®: A Game-Changer for Pipeline Construction and Weld Zones
Lined Pipe Systems (LPS) recognized the limitations of traditional weld zone protection methods and developed a revolutionary solution: FlexSleeve®. This pre-fabricated, welded joint cladding system eliminates the need for field-applied coatings at the weld zone, offering a faster, safer, and more reliable alternative.
Here’s how FlexSleeve® streamlines the construction process and conquers corrosion challenges:
Faster Installation
FlexSleeve® joints arrive pre-coated and ready for installation. Once welded into place, the joint is ready to go after Non-Destructive Examination (NDE). No further internal cleaning, coating, or inspection is required, significantly reducing construction time. For smaller diameter pipes (under 48 inches), FlexSleeve® can cut construction time in half or even better.
Quality Assurance
Unlike field-applied coatings, which are susceptible to human error and inconsistencies, FlexSleeve® is manufactured in a controlled environment. This ensures consistent internal joint protection, eliminating quality issues and guaranteeing a flawless, corrosion-resistant barrier.
Enhanced Welding Efficiency
FlexSleeve® functions as a backing ring during the welding process. This backing ring provides support for the weld pool, enabling faster and higher-quality root passes for both automatic and manual welding methods. Faster welding translates to faster project completion.
