Pipe static and - dynamic

Pipe static analysis

• Static analysis according to I. and II. order theory with linear and nonlinear boundary conditions,
  as well as special fields of pipe static analysis like
  - continuous elastic foundation for soil restraint pipes
  - nonlinear bedding
  - hanger displacement and friction,
  - jacket piping
  - Plastic piping with stress analysis (PE, GRP)

Pipe dynamic analysis

• dynamic analysis acc. to modal response or direct integration method with linear and nonlinear boundary conditions
• eigen frequencies, mode shapes, earthquake, fluid hammer
• any time dependent loads

Stress analyses

• ANSI/ASME B31.1, B31.3, B31.4, B31.5, B31.8
• EN 13480, FDBR, AGFW, KTA3211.2, KTA3201.2
• ASME-Code Section III NB/NC/ND, Stoomweezen D1101
• Plastic pipes acc. to ISO14692, BS7159, KRV

Calculation of steel structural sections

• Supports and pipe racks according to DIN 18800

Pressure loss and Temperature loss calculations

• Calculation of pressure and temperature loss in intermeshed pipe systems with compressible and incompressible media
• Calculation of insulation thickness of pipes
• Pressure and temperature loss calculation of district heat networks
• Dimensioning and analysis of sprinkler systems

Finite Element Analysis

Components, e.g. branches under internal pressure and additional loads
