Hydraulic Hoses for the Shipbuilding Industry

High-Performance Hydraulic Hoses

We supply high-performance hydraulic hoses, specifically designed to meet the needs of the shipbuilding industry, especially for the most demanding applications such as offshore vessels, CSOVs, SOVs, OSVs, as well as offshore wind farms and subsea installations.

Our hoses are made from top-grade pipes such as T211 (2SN), T221 (2SC), T911 and T912 (4SP and 4SH), with diameters ranging from 5 to 51 mm, and are designed to withstand hydraulic oil temperatures from -40°C to +100°C.

BV Type Approval Certification

Tecalemit Flexibles holds type approval certificates issued by Bureau Veritas for its crimped hydraulic hoses.
These certificates confirm our products' compliance with the strict requirements of Bureau Veritas Marine & Offshore, ensuring their suitability for installation on steel ships, offshore platforms, warships, and pleasure yachts.

We also manufacture metallic-reinforced hoses certified "BV Marine", as well as stainless steel corrugated metal hoses approved by Bureau Veritas.
These products are designed for maritime and offshore applications, including cruise ships, ferries, RoPax vessels, tugboats, as well as for critical missions such as heavy lifting, mud pumping, marine towing, and cargo transport.

Expertise

The tests conducted as part of these certifications, including fire resistance tests, ensure not only maximum reliability but also enhanced durability and safety.
Our hydraulic hoses are designed to operate in harsh conditions, ensuring easy maintenance and maximum availability — essential criteria for offshore operations or strategic military missions.

As an "open source" manufacturer, we offer customized solutions tailored to the specific needs of each project. We also offer retrofitting and new construction options, while complying with environmental regulations and optimizing both CAPEX and OPEX.

With over a century of experience and recognized technical expertise, Tecalemit Flexibles is your trusted partner for the supply of certified hydraulic hoses.
Whether it's for hybrid propulsion, submarine cable installation, or emergency interventions at sea, our products deliver the performance and reliability you need to successfully execute your complex and demanding projects.

Hydraulic Hoses for the Railway Industry

Safe Hydraulic Hoses

Safety is a top priority in the railway sector, especially for equipment exposed to fire hazards. All components used in rolling stock must meet strict requirements to ensure the protection of passengers and staff in the event of an emergency.

Tecalemit Flexibles meets these requirements by offering a range of high-performance hydraulic and pneumatic hoses specifically designed for the railway industry and compliant with the EN 45545-2 standard. This unified standard, adopted by all EU countries, ensures optimal hose performance in case of fire by limiting flammability and smoke emission.

Our hoses are perfectly suited for fluid transport systems (oils, fuels, water…), hydraulic and pneumatic braking systems, as well as suction and discharge applications for hydraulic circuits. They provide excellent thermal and chemical resistance, along with high flexibility, essential for complex railway installations.

MANURAIL®: Pneumatic Tubes

As part of our commitment to sustainable and high-performance solutions, Tecalemit Flexibles has developed the MANURAIL® range, consisting of pneumatic tubes made of PA 11 HFFR RILSAN B polyamide.
- Full compliance with EN 45545-2 for maximum fire safety
- Excellent cold impact resistance, ensuring increased reliability in extreme conditions
- 89% bio-based, made from 100% renewable raw materials
- French manufacturing: extruded in Brittany (Pont-l’Abbé) with raw materials sourced from Normandy
Thanks to its thermal, chemical, and mechanical resistance, the MANURAIL® range is ideal for fuel lines, hydraulic and pneumatic circuits, and braking systems of railway vehicles.

Quality Commitment and French Manufacturing

With its expertise and industrial know-how, Tecalemit Flexibles is a trusted partner for railway industry players.
