Simple and Reliable Design, Analyses and Testing
Excellent Safety for Long-Term Use

Our high-pressure testing equipment employs various pressure media with a highly safe and secure structure consisting of a cylindrical pressure vessel, top/bottom closures, and a press frame to hold the axial force. This structure allows for simple and highly reliable fatigue-resistant design, stress analyses, and nondestructive testing, assuring a high level of safety for long-term use.
