Advanced Rotolining Solutions

Rotolining, also known as rotational lining, is a specialized process used to apply a seamless, corrosion-resistant lining to the interior of pipes and fittings. This method ensures complete and uniform coverage, making it ideal for protecting components exposed to harsh chemicals, abrasion, and extreme operating conditions.

How Rotolining Works

The rotolining process involves placing a thermoplastic material inside a pipe or component, which is then heated and rotated on multiple axes. As the material melts, it evenly coats the interior surface, forming a consistent, pinhole-free lining.

This process results in:

Uniform wall thickness
Seamless interior coating
Strong adhesion to the substrate
Long-lasting protection

Benefits of Rotolining

Rotolining delivers measurable advantages over spray-applied or sheet-based lining methods, particularly in the high-wear, high-corrosion, and high-erosion environments common to oil and gas operations:

Excellent corrosion resistance
Superior chemical resistance
Increased service life of piping systems
Reduced maintenance and downtime
Smooth internal surface for improved flow efficiency

Materials Used

We utilize a variety of high-performance thermoplastics depending on the application, including:

Applications

Rotolining is widely used in industries where internal pipe protection is critical, including:

Rotolining vs. Other Internal Pipe Protection Methods

Rotolining differs from spray-applied internal pipe coating in how the lining is built up. Because the thermoplastic material is heated and rotated as a single continuous application, rotolining produces a uniform wall thickness with no seams, weld lines, or overlap points, an advantage on fittings, elbows, and other components with complex internal geometry where spray or sheet-lining methods can leave thin spots or require multiple passes to achieve full coverage.

For straight-run pipe and larger-diameter components, internal pipe coating may be the more practical or cost-effective option. Our team can help determine which method fits a given project’s geometry, chemical exposure, and budget.

Frequently Asked Questions

What is rotolining and how does it protect pipe?

Rotolining, also called rotational lining, is a process that applies a seamless thermoplastic lining to the interior of a pipe or fitting. The lining material is heated and rotated on multiple axes inside the component until it melts and coats the interior surface evenly, creating a uniform, pinhole-free barrier against chemical attack, abrasion, erosion, and corrosion.

What materials can be used for a rotolined pipe interior?

We work with a range of high-performance thermoplastics, including PTFE, ETFE, ECTFE, FEP, PVDF, and other fluoropolymers. Material selection depends on the chemicals, temperatures, and pressures the pipe or fitting will see in service.

How is rotolining different from spray-applied internal pipe coating?

Spray-applied coatings build up a lining in multiple passes and can leave thin spots on components with complex shapes. Rotolining applies the lining in a single continuous, rotating application, which produces a more uniform wall thickness and is often better suited to fittings, elbows, and other irregular geometries.

Which industries use rotolining?

Rotolining is common in oil and gas, chemical processing, petrochemical, water and wastewater treatment, and general industrial manufacturing, wherever internal pipe protection against corrosive or abrasive media is critical.

How long does the rotolining process take?

Timelines depend on the size, diameter, and material of the components involved, along with current shop volume. Contact us with your project specs for a turnaround estimate along with your quote.
