PLE optimizes your piping and pipeline design

PLE is the piping and pipeline software for advanced material behaviour and complex failure mechanisms for standard and non-standard verifications and indepth stress-strain assessments. PLE enables you to model above ground piping systems and underground pipelines and networks together in 1 model.

Piping and Pipeline Stress-Strain Assessments

PLE - The Software

A general applied mechanics-oriented software program with pipeline, soil and water oriented structural elements

PLE combines advanced engineering logic with user-friendly functionality to deliver precise and powerful analysis of underground pipelines. The following key features form the foundation of the software’s value proposition:

Comprehensive 3D Geometric Modeling
Detailed Definition of Pipe, Soil, Loadings & Boundary Conditions
Advanced Analysis Methods
Dual-Stage Result Reporting

Key Benefits

1. Comprehensive 3D Geometric Modeling

PLE represents the pipeline using a sequence of straight pipe segments, elastically curved bends, supports, joints, and (T-) connections. It supports complex layouts including branches, loops, and pipe-in-pipe configurations, enabling highly realistic and versatile modeling for even the most intricate pipeline systems.

2. Detailed Definition of Pipe, Soil, Loadings & Boundary Conditions

Each element of the pipeline system—material properties, soil interaction, external and internal loadings, and boundary conditions—can be defined in detail and independently, with full flexibility to vary these characteristics along the pipeline axis. This granular control ensures that the model reflects real-world conditions with high fidelity.

3. Advanced Analysis Methods

PLE supports a wide range of analysis techniques, including linear elastic (an)isotropic and elasto-plastic isotropic pipe materials. Non-linear soil behavior is always taken into account. Users can select between geometric linear and non-linear behavior, define loads with or without design factors, and apply sequential loading scenarios.

4. Dual-Stage Result Reporting

Results are generated using a hybrid Finite Element Method (FEM) in two stages. The first provides longitudinal (beam) behavior such as pipe displacements, internal forces, and soil/external support reactions. The second evaluates cross-sectional behavior, including longitudinal and circumferential stresses and strains, and Hoop stress. This layered approach offers both macro and micro-level insights essential for sound engineering decisions.

Work fields

The Software that is successfully in all piping and pipeline projects.

Medium – (natural)gas

Due to the serious consequences of potential gas pipe leakage, ensuring the integrity of joints and connections is critical. In PLE, the exact position and type of each joint or connection can be modeled along with the expected loads, allowing detailed analysis and definition of the necessary data for each component.

Medium – green gas

Any specific requirements or pipe materials for green gas pipelines can be modeled and analyzed in PLE.

Medium – water

Water pipelines sometimes involve a variety of pipe materials and installation techniques within a single project. These can be easily combined and analyzed in PLE. When connecting a new section to an existing pipeline, evaluating the loads on the connection and ensuring watertightness are critical. PLE provides the necessary tools to assess all of these factors.

Technical Specials

The Software that enables you to optimize even the most complex technical situations.

Steel pipelines

Steel pipelines are the core of the program, the first type that was implemented, and the one with the most possibilities. Straight pipes, elastic bended pipes, hot-bended prefabricated bends, everything is possible and can be analysed using general best practice methods or using methods described in several codes and norms.

Concrete pipelines (general)

Concrete pipelines are usually laid using prefabricated segments connected by Socket-spigot connections. These articulated pipelines can be modelled in Ple4Win, the program in these situations will also check the movements and rotations in the joints and warn if leakages or freeze-up’s occur at any connection.

Cast iron pipelines

Cast irons pipeline are usually old pipelines, these can be modelled in Ple4Win as articulated pipelines. Ovalisation of the pipelines are calculated, as are stresses in the pipe, both results can be used to check whether the pipe will crack or implode. Furthermore, Ple4Win will check the movements and rotations in the joints and warn if leakages or freeze-up’s (danger of fragments splintering off at the rim) occur at any connection.
