What do our marine piston rings do?
Large Bore Diesel Engines
Marine piston rings play a vital role in the engines used in ships. The increasingly super-charged and high-performance engines are developed as the main marine engine. Therefore, piston rings have to withstand intense conditions such as shock, high temperatures and insufficient lubrication, all of which leads to excessive wear and breakage.
At HP Rings, we offer a range of standard rings available for different operating conditions. Our piston rings are developed using the latest materials and coatings and cover the different sets supplied by the engine builders: basic set (Non-Coated), Quick Running-in Version (Soft Coated) and Heavy Duty Version (Hard Coated for longer TBO).
Medium Bore Diesel Engines
Rapid progress has been made in the development of four-stroke engines that are used in ships and power plants. However, supercharged, high-speed engines have their requirements for cost-effective running. This includes cheaper running costs through minimising lubrication consumption and the need for high reliability and improved durability. Our piston rings have the latest coatings and materials and combine excellent oil scraping and wear-resistant properties.
