At Anvis, we don't just supply parts: we co-develop your solutions of tomorrow.
Our added value is based on supporting our clients at each stage of their projects.
Defense application
High acoustic & vibration performance for naval defense.
A Historic and Strategic Partnership. For many decades, Anvis has established itself as the long-standing partner of major players in military shipbuilding. We design and develop tailor-made elastomer anti-vibration solutions essential to the success of missions at sea. Whether surface vessels or submarines, our technologies guarantee acoustic discretion, the protection of critical equipment and the comfort of crews in the most extreme conditions.
Beyond the component: A true engineering partner
Excellent advice & design
Thanks to the expertise of our engineers, we work to design vibration isolation systems perfectly suited to your space and operating constraints.
Advanced testing facilities
The validation of our solutions is based on qualifications according to strict specifications. We have our own testing facilities to simulate the real constraints of the marine environment: Dynamic and static test benches. Elastomer characterization tests. Accelerated aging and resistance to “Marine” environments tests.
The guarantee of a qualified supplier
Trust is earned by complying with the strictest requirements of the Defense sector. Anvis is proud to be a Qualified Supplier to the largest naval contractors.
Sustainability: Commitment to maintaining operational condition (MCO) over the long term.
Our expansion joints and special joints for marine applications have proven their quality and durability between two operations under the French Navy's operational conditions.

FREQUENTLY ASKED QUESTIONS
Frequently Asked Questions
An expansion joint is a flexible element inserted into the pipes of warships (frigates, submarines, aircraft carriers). It is designed to absorb movements, thermal expansion, and isolate vibrations between the different equipment (motors, pumps) and the ship's hull.
The Dilatoflex® expansion joints installed on military vessels have been subject to qualification by the technical services of major prime contractors, who validate that the design complies with military specifications and safety standards at sea.
For Defense, the expansion joints installed in critical areas (engine rooms, combat compartments) must comply with strict fire resistance standards (e.g. ISO 15540 / ISO 15541), guaranteeing that they remain waterproof even after direct exposure to flames for at least 30 minutes at more than 800°C. The use of fire-resistant covers makes it possible to comply with this requirement.
Based on the client's technical specifications, our engineers design specific anti-vibration solutions with the associated qualification program carried out by us (aging studies, cycling tests, etc.) in true partnership with the client throughout the project and respecting the confidentiality inherent in these programs.
The defence sector requires full traceability (Grade A / Level 1). Each expansion joint is supplied with a manufacturer's file including, as applicable:
- Material certificates (3.1 according to EN 10204) for elastomers, fabrics and straps.
- Hydrostatic test reports (unit or statistical test pressure).
- Dimensional control reports.
- Certificates of conformity to specified military standards.
