silencers with the u-stamp certification

U-Stamp Certified In-line Silencers: Innovation and Safety for Industrial Compressors

As part of a growing commitment to excellence and internationalization, the first project entirely carried out under U-Stamp ASME certification has recently been completed. This involved a strategic supply of in-line silencers designed for the U.S. market, developed to meet specific acoustic and performance requirements. The result represents a significant milestone in the ability to deliver solutions that comply with the highest global standards.

A Leading Client in the Rotating Machinery Sector

The project involved the supply of in-line silencers for dual-stage compressors, intended for a well-known U.S. manufacturer of rotating machinery, a key player in the global industrial sector.

Custom Engineering Based on Client Specifications

Each silencer was designed to meet precise acoustic, fluid-dynamic, and mechanical requirements, tailored to the operating characteristics of the compressors. The design was optimized to ensure high performance in terms of noise reduction and structural reliability.

Performance and Safety, a Comprehensive Engineering Approach

Effective Noise Control Across All Operating Conditions

The silencers were engineered with appropriate safety margins to ensure effective noise attenuation, even under the most demanding working conditions. Acoustic analyses played a key role in validating the expected performance.

Prevention of Acoustic and Mechanical Resonance

Frequency analyses were conducted to prevent resonance phenomena, taking into account the rotational
speeds of the compressors and the natural frequencies of the proposed assemblies. By optimizing geometry, stiffness, and mass distribution, the design eliminated vibration issues throughout the entire operating range.

Certified Internal Cleanliness

As with all products directly connected to compressors, advanced manufacturing techniques were used to ensure the absence of particles larger than 100 microns. Internal cleanliness was certified through flushing tests carried out during final inspections.

U-Stamp Certification: A Guarantee of Quality and Global Compliance

What is the U-Stamp Certification?

The U-Stamp certification is an official recognition issued by the American Society of Mechanical Engineers (ASME) for pressure equipment built in accordance with ASME Section VIII. It is a mandatory requirement for marketing such equipment in the U.S. market.

Technical and Operational Advantages

With this certification, every phase of the manufacturing process, from design to production and testing, follows strict, traceable procedures. Choices regarding materials, welds, and inspections are made according to the most rigorous international standards, minimizing the risk of failure or malfunction.

Traceability and Registration with the National Board

A major advantage of U-Stamp certification is the possibility of registering the products with the U.S. National Board, an essential step for legal installation of pressure equipment within the United States.

Conclusion

The success of this first U-Stamp certified project demonstrates the ability to deliver advanced, safe, and internationally compliant acoustic solutions. It marks an important achievement that opens new opportunities in the global industrial noise reduction market.
