Pipe and machine networks
Piping networks and associated machines are highly stressed mechanical assemblies, subject to pressure loads, thermal variations, pulsating excitations and complex dynamic stresses. In industrial installations incorporating compressors, rotating equipment or pressurized processes, control of these phenomena is essential to guarantee mechanical strength, prevent fatigue failures and ensure continuity of operation.
SIM Engineering is involved in the analysis, modeling and optimization of networks and equipment, with a focus on reliability, standards compliance and sustainable performance.
Integrated expertise in network dynamics, pulsation and flexibility
SIM Engineering’s expertise is based on an in-depth understanding of the interactions between machines, fluids and structures. Pulsation, vibration and thermal expansion can combine to generate critical stresses on lines, supports and connections for sensitive equipment.
The approach developed integrates pulsation analysis, mechanical modeling, flexibility calculations and dynamic studies in compliance with applicable standards (API 618, API 619 and associated calculation codes). The aim of each mission is to objectivize real loads, identify the mechanisms at the origin of disorders and propose technical optimizations adapted to operating constraints.
Our services
Our piping and machinery expertise is built around four complementary services.
- TheAPI 618 Study deals with pulsations and vibrations generated by reciprocating compressors to prevent the risk of network fatigue.
- TheAPI 619 study concerns screw compressors, with analysis of pulsation-acoustic-vibration couplings and optimization of discharge lines.
- Pipe vibration measurements can be used to characterize dynamic operating levels, assess criticality and define targeted corrective actions.
- Finally, ourpipe network flexibility study analyzes thermal expansion and combined loads to guarantee mechanical strength and limit the forces transmitted to equipment. Together, these services form a coherent offering dedicated to securing and optimizing industrial installations under dynamic and thermal constraints.
