Title: A Nimal Liyanage: Innovator in Pressure Regulation and Corrosion Resistance
Introduction
A Nimal Liyanage, located in Chiyoda, Japan, is a notable inventor with a focus on advancements in pressure regulation and welding technologies. With a total of two patents to his name, Liyanage's work addresses critical issues in gas distribution systems and enhances the durability of welding applications.
Latest Patents
Liyanage's latest innovations include:
1. **Method and system for assessing the operating condition of a pressure** - This method involves detecting malfunctions in a pressure regulator during its operation in corrosive or reactive gas environments. By continuously measuring the output pressure of the regulator, both with and without gas flow, it allows for predicting potential failures based on fluctuations in differential output pressure. When these fluctuations exceed a certain experimentally determined value, it indicates a failure in the pressure regulator or the overall system.
2. **Corrosion resistant welding of stainless steel** - This process focuses on welding stainless steel tubing using an inert gas that includes a silicon base gas, particularly silane (SiH₄). During the welding process, silicon is deposited at the weld joint through chemical vapor deposition, significantly improving the corrosion resistance of the weld.
