Our know-how

Design office

Support and compliance

Our engineering department relies on experienced teams to support customers from the tender phase onward, balancing technical requirements, quality, costs and delivery schedules.

SPM also performs conformity assessments in accordance with PED 2014/68/EU and ESPN requirements, either as manufacturer or in support of its customers.

Project management

Responsiveness and coordination


The versatility of our project managers and SPM’s integrated organization ensure responsive project management capable of adapting to our customers’ technical, documentation and scheduling requirements.


Supported by shared monitoring across departments, our organization strengthens activity coordination, resource control and the conformity of documentation fully produced in-house.

Flow measurement calculations

Accuracy and sizing


SPM develops its own in-house calculation tools for the sizing of process equipment and the definition of their operating characteristics.


We notably design flow measurement equipment compliant with ISO and ASME standards, as well as single- or multi-orifice flow restrictors developed using SPM’s proprietary methodology, including cavitation control and stage optimization.


Depending on the required level of accuracy, performance can be validated on certified test benches in order to refine characteristic coefficients and consolidate sizing data.

Pressure strength calculations

Validation and reliability


SPM verifies the pressure integrity of its equipment using in-house calculation tools to validate geometry, thickness, and material selection for each component.


Calculations are performed in accordance with major design codes (RCC-M, NF EN 13480, ASME B31.1 / B31.3, CODAP, CODETI).


SPM also verifies the pressure resistance of test tooling, ensuring safe and reliable pressure testing.

Finite-element analysis

Insight and control


SPM provides static and dynamic finite element analysis to validate pressure integrity and assess equipment behavior.


These analyses help refine design parameters and secure technical choices, particularly for complex geometries or demanding operating conditions.

CAD

Precision and continuity


Each equipment is modeled in 3D CAD and then used by the methods department for CAM programming and assembly phases.


Drawings are developed to cover the full lifecycle: manufacturing (detail drawings), assembly (assembly drawings), testing (tooling and instrumentation layouts), and on-site installation (general arrangement and interface drawings).
