GF Piping Systems introduces HEAT-FIT: The Pioneer Fire Retardant Solution for Thermoplastic Piping Systems in the Shipbuilding Industry

HEAT-FIT Jacket System, composed of pipes, fittings, and valves being fire tested
With HEAT-FIT, GF Piping Systems launches the first fire-retardant pipe jacket solution, an innovation to bring lightweight, corrosion-free thermoplastic piping systems for essential applications onboard.

HEAT-FIT will be presented at Seatrade Cruise Global in Miami between 25 and 28 April 2022.

The demand for thermoplastic piping systems has grown considerably over the last few years. The extensive use of plastic piping can make ships more efficient while reducing costs. The newly developed HEAT-FIT Jacket System, allows thermoplastic piping systems to be used for essential applications (L3) onboard cruise ships, merchant vessels, and offshore platforms. These applications have especially high safety standards, including fire resistance.

HEAT-FIT is designed to be compatible with the ecoFIT product family by GF Piping Systems, a range of polyethylene pipes and fittings for use in industrial applications and water and wastewater treatment. The new lightweight pipe jacket system consists of two layers of TPU. Between the TPU layers, HEAT-FIT features a high-temperature fiberglass fabric that protects the pipe beneath, as well as an intumescent coating that is non-toxic and water-based, an environmentally safe material. In the event of a fire, this graphite char coating expands and creates a protective barrier. As a result, HEAT-FIT is capable of withstanding temperatures of up to 1000°C for 30 minutes at a pressure of 3 bar. The system can easily be installed and retrofitted without additional training and features a scratch and stain-resistant coating specially developed for the demands of the harsh marine environment.

As part of its more than six years development phase, the HEAT-FIT fire-retardant system was subjected to a wide range of tests. These included fire resistance in accordance with the IMO Res. A753 fire endurance L3 Code, and surface flammability as well as smoke and toxicity in accordance with IMO Res. A653 2010, FTP Code Part 5 and Part 2. In addition, GF Piping Systems conducted waterproof testing in seawater, saltwater spray, and water contaminated with diesel fuel. The approval process for these tests is currently being overseen by the relevant governing bodies DNV, LR, RINA, ABS, and Bureau Veritas. Roberto Chiesa, Head of Business Development Marine at GF Piping Systems, comments on the launch of the new piping system: ” In the past, we have already shown that plastic piping systems can make ships more efficient. HEAT-FIT is the ideal solution to increase the efficiency of vessels. Another fantastic innovation our team created on our journey to a more sustainable world, improving energy efficiency for life.”

HEAT-FIT will be first presented to the public at Seatrade Cruise Global in Miami (USA), taking place on April 25 – 28, 2022. Visit us at booth #4233.
