PlantWare engineers pipe supports

• RIGID: for fix-points (lateral and/or axial)
• SPRING: Based on Pipe Flexibility / Stress Calculation
• CONSTANT HANGERS: Based on Pipe Flexibility / Stress Calculations

We produce manufacturing drawings for both the pipe clamps as well as the hanger itselv and pipe supports.

Calculation of flange connections according to EN 1391: Special flange connection like

• I.G. Norm flanges with lens sealing
• High-pressure flanges w. weld neck
• High-pressure flanges with threaded hub and loos flange

 Calculations covers

• Bolting calculation with nessesary assembly forces
• Gasket - all materials and shapes according to EN 1591
• Flange - the flange it self
• Hub - if the flange connection is with loos flange.

PlantWare performs pressure loss calculations for single pipes and whole systems. We are using PIPE-FLO from Engineered Software Inc. for system modeling and pressure loss calculations as well as pump selection.

From the flow model can be used for both static and dynamic calculations of the flow system.

Sizing and selection of Control Valves using CONVAL software tool including the whole control loop.

Control Valve will be selected based on actual measured conrol valve curves.

PlantWare performs stress analysis of pipes based on the ROHR2 software package according to EN 13480 or ASME 31.6:

• Flexibility analysis and support design
• Spring support selection and dimensioning
• Flexible joint selection and dimensioning
• Support load determination
• Stress analysis

GRP Piping for special systems in both FGD-plants as well as industrial plants such as

• Slurry systems
• Acid / Lye system
• Sea water / salt water systems
• Special Waste System
• Sub-tarrain piping

PlantWare does detail engineeing of piping and pipe support for above mentioned systems.

PlantWare offers our services within pipe design:

• Pipe isometrics for fabrication
• Pipe isometrics for erection
• Isometric pipe drawings

Pipes will be engineered and documented according to pipe specification/class from either PlantWare company standard or customer standard.

Pipe supports are engineered with either commercial products like LISEGA or custom application.

We uses AVEVA 3D PDMS softaware package for pipe design.

Example 1:
Blow off pipe from steam system - See Pipe Isometric

Example 2:
Blow off pipe from tank - See Pipe Isometric
