Whether you’re designing a new high-pressure system or troubleshooting an existing one, WHA ensures your system meets codes, performs reliably, and operates safely.
WHA has over 90 years of combined engineering experience in a wide range of pressure systems, from complex rocket engine test facilities to low-pressure calibration systems. We ensure your systems are code-compliant, safe, and optimized for performance, including systems handling oxygen, hydrogen, or other hazardous fluids.
Pressure System Design Review
WHA reviews preliminary designs for code compliance, safety, and operational performance. Our advanced fluid system modeling can help confirm that the desired flow, pressure, and temperature are delivered by each system.
We also assess existing systems to resolve operational issues, address safety concerns, and enhance functionality.
Systems with Hazardous Fluids
Our in-depth experience covers the unique requirements of many operating fluids like oxidizers (oxygen, nitrous oxide) and fuels (hydrogen, methane), hypergolic (hydrazine family and mixed oxides of nitrogen), pyrophoric, and many more.
