Full-Length Internal Tube Protection for Maximum Service Life
The plastocor® Tube-Lining System provides comprehensive internal protection along the entire length of heat exchanger tubes. This system is engineered to combat corrosion and erosion from within the tube, offering a long-term solution to one of the most persistent problems in power plants and process industries.
As an Approved Applicator of plastocor® Technology, Arudra has successfully implemented this system across numerous critical installations throughout India and Asia since 2003, helping customers extend equipment life while avoiding costly tube replacements.








of Experience
Why Internal Tube Lining?
Heat exchanger tubes degrade over time due to corrosion, MIC, and erosion. Traditional repairs like sleeving or re-tubing are costly and temporary. The plastocor® Tube-Lining System offers a durable, cost-effective solution that protects tube integrity while preserving thermal performance.
Key Benefits
It coats the full internal tube surface with minimal wall loss, maintaining efficiency. The lining bonds to copper, brass, and stainless steel, resists harsh chemicals, seals micro-cracks, and prevents leaks—without altering tube geometry or requiring invasive procedures.
Where It's Applied
The plastocor® Tube-Lining System is ideal for:
Condensers in thermal and
nuclear power stations
Surface condensers in
refineries and chemical plants
Intercoolers, feedwater heaters,
and process coolers
Any application where
tube degradation threatens reliability
It is especially valuable for aging heat exchanger or condenser units where internal corrosion has developed over time,
but full tube replacement is not practical due to budget limitations, extended downtime risks,
or constraints in system design and accessibility.
Our Expertise in Application
Arudra’s technicians are extensively trained and certified by plastocor International SA, ensuring expert application every time.
We use advanced surface preparation and precision spraying techniques to achieve uniform coating thickness and consistent protection
across the entire tube bundle.
Strict quality control is built into every stage of the process, including adhesion testing, holiday detection, and detailed post-application inspection.
This guarantees that every application meets international standards for performance, durability, and reliability.

Let Arudra and plastocor® bring international-grade reliability and protection to your heat exchanger tubes — from the inside out.
Why Protect Tube Inlets?
The inlet section of heat exchanger tubes is subject to the most aggressive flow patterns and mechanical wear. Common issues include:
The plastocor® Tube-Inlet System addresses these challenges through a reinforced, high-performance coating that forms a seamless bond with the base metal, reducing further damage and eliminating the need for frequent re-tubing.
System Features & Advantages
- Targeted Protection: Coats 1″–2″ of the inlet section where erosion is most intense
- Reduced Maintenance: Extends tube life and reduces frequency of re-tubing operations
- High Bond Strength: Exceptional adhesion to ferrous and non-ferrous substrates
- Superior Durability: Designed to withstand abrasive flows and corrosive water chemistry
- Maintains Thermal Efficiency: Minimal impact on heat transfer rates
- Quick Application & Cure Times: Reduces downtime and enables rapid return to service

Industry We Serve
The plastocor® Tube-Inlet System is widely used across:

Power plants (coastal, thermal, and nuclear)

Refineries and petrochemical facilities

Fertilizer plants and desalination units

Pulp & paper mills and other industrial utilities
Whether it’s planned maintenance or an urgent repair, plastocor® high-performance coating systems provide a trusted and efficient solution. Instead of costly and time-consuming tube replacement, these advanced systems restore the integrity of heat exchanger tubes, ensuring long-term reliability, corrosion resistance, and sustained thermal efficiency across operations.
