Applications

Ballast Water System

We offer durable plastic pipes (0-40°C) for efficient ballast water management. Resistant to seawater & chemicals, they ensure a long, maintenance-free lifespan (up to 25 years), minimizing downtime and costs. Ideal for marine applications and industrial water piping.

Ballast Water Treatment

Prevent invasive species with proper ballast water treatment (BWT). Traditional piping struggles with seawater & chemicals, leads to leaks & downtime. We offer BWT-ready, corrosion-resistant solutions and prefabricated skids by OEMs for fast on/offshore integration.

Water Engine Cooling

Plastic pipes prevent corrosion & erosion for reliable freshwater & seawater cooling. HEAT-FIT fire retardant jackets enable cooling in critical areas (machinery spaces, A/B pump rooms, accommodation, control & open decks) meeting fire regulations.

Fresh Cold and Hot Water

Our highly efficient water supply systems featuring corrosion-resistant pipes (Instaflex (PB) or iFit) deliver fresh water to cabins, kitchens, restaurants, and bars on all types of ships. Flexible for easy install, saving time & cost for reliable potable water delivery.

Sewage, Black and Grey Water

Our reliable pre-insulated plastic piping system provides highly efficient transport of cooling media and sustains the energy efficiency of the insulation up to 30% more efficient preventing Leaks and refrigeration problems can result in high costs and food waste.

FAQs

What plastic materials are best for use on merchant ships?

The material selection for passenger ships depends on specific operational needs. Below are commonly chosen plastics and their unique advantages:

  • Polyethylene (PE): Valued for its elasticity and corrosion resistance, PE is versatile across various ship systems including ballast water, water treatment, exhaust gas scrubbers, and cooling systems for fresh and seawater. Its flexibility helps absorb torsional and vibrational stresses, enhancing vessel performance.
  • Polybutene (PB): Recognized for its exceptional creep resistance and chemical durability, PB is ideal for applications such as drinking water systems, compressed air lines, and chilled water circuits. It ensures water purity without imparting taste or contaminants, meeting stringent hygiene standards for potable water.
  • Polypropylene (PP): Due to it's high chemical resistance, the two variants of PP systems, Random Copolymer (PP-R) and Homopolymer (PP-H), are favored for drinking water applications and black and grey water applications on board. It offers high flexibility, which is crucial for adapting to torsional and bending stresses in ship structures.
  • PVC Materials: PVC-C (Chlorinated Polyvinyl Chloride) and PVC-U (Unplasticized Polyvinyl Chloride) are also used depending on specific application needs. PVC-C offers enhanced temperature and chemical resistance for demanding marine environments, while PVC-U excels in mechanical strength for rigid piping systems.
  • HEAT-FIT Fire Retardant System The HEAT-FIT fire retardant system is highly insulating and robust, protecting the medium-carrying inner pipe (PE100) from fire. The flame-retardant coating reacts upon exposure to flames, forming a protective layer that shields the pipe from heat and fire. 

In addition, advanced solutions like multilayer pipes and fittings, as well as pre-insulated pipes such as COOL-FIT (pre-insulated PE), deliver added benefits. Multilayer designs optimize performance under varied conditions, while pre-insulated pipes enhance energy efficiency and environmental resilience.

Each plastic material undergoes rigorous testing and certification to meet stringent safety and performance standards essential for marine applications. Their lightweight nature, ease of installation, and resistance to corrosion collectively contribute to enhanced efficiency and durability in maritime operations.

Does any piping comply with FTP Code Part 5 and 2?

Yes, GF Piping Systems offers piping solutions that comply with FTP Code Part 5 and Part 2 requirements. Specifically, SeaCor (PVC-C) meets these standards and is approved by the US Coast Guard (USCG) for non-essential applications in marine environments. This approval ensures that Seacor piping maintains the necessary safety and performance standards outlined in the FTP Code, making it suitable for various marine applications where compliance is crucial.

Are plastic piping systems suitable for chemical transport on board?

Plastic piping systems generally exhibit good corrosion resistance, making them suitable for many chemical transport applications on board ships. However, the suitability depends heavily on specific factors such as the working conditions (e.g., temperature, pressure) and the concentration of the media being transported.

What are the installation advantages of plastic marine pipes?

Due to their lightweight nature, flexibility, easy jointing technologies, and prefabrication options, plastic piping systems offer ease of installation. Faster installation and simplified maintenance can improve project timelines and overall efficiency for shipyards, reducing labor hours and straightforward integration with other systems.

How do thermoplastic piping systems improve operational performance on board ships?

Plastic pipes, fittings and valves resistance to corrosion and long-term durability can contribute to higher construction quality and reliability. The improved operational performance can reduce rework, warranty claims, and post-delivery issues, leading to higher customer satisfaction and the reputation of shipyards.

What makes GF's marine pipes and fittings more reliable and hygienic for marine applications?

Marine pipes and fittings made from thermoplastic or multilayer composites require minimal maintenance and offer long-term durability. They do not require regular painting or coating to prevent corrosion, reducing maintenance costs and downtime. The smooth inner surface of plastic pipes also minimizes the risk of fouling and scaling, further facilitating maintenance procedures.
