Oil & Gas
Contributing to the expansion of natural gas
Valves & Fittings for oil, gas and downstream operations
ALSYMEX produces valves & hydraulic power-driven connection systems for transfer installations and loading arms for liquefied natural gas (LNG). ALSYMEX supplies those equipments to system integrator clients operating in the oil and gas and petrochemical sectors on projects that are international in scope.
In partnership with its clients, ALSYMEX has developed its expertise as a designer of systems for cryogenics. ALSYMEX has a human-scale Design & Engineering Department that is both flexible and responsive. We develop skills for verifying the behavior of materials by finite element analysis. Our design efforts focus on reliability, safety, ease of maintenance and the competitive costs of manufacture and operation.
ALSYMEX expertise
Safety Control Solutions
ALSYMEX also has a Control Systems Department mainly dedicated to Oil & Gas, but with extensive in ATEX (explosive atmospheres). Based on straightforward functional specifications, ALSYMEX has all the necessary skills and resources to design, program, build and commission complete control systems with supervision mode. These systems control both onshore and offshore installations.
