Defines acceptable forces and moments on pump nozzles to avoid casing distortion, shaft misalignment and excessive vibration. Widely used in refineries and chemical plants.

Provides allowable nozzle loads and connection limits for compressor casings. Ensures pipe-induced forces do not impact rotor alignment or dynamic behaviour.

Covers air-cooled heat exchangers inlet/outlet load limits. Ensures pipe-induced forces and moments do not cause any damage to heat exchangers.

Defines mechanical requirements and connection limitations for fired heaters. Evaluates whether piping loads remain within heater manufacturer limits.

Defines acceptable forces and moments on pump nozzles to avoid casing distortion, shaft misalignment and excessive vibration. Widely used in refineries and chemical plants.

Specifies maximum nozzle forces, moments and allowable deflections for steam turbines. Used to prevent casing distortion and coupling misalignment.

Provides procedures to calculate local stresses at vessel nozzles due to external piping loads. Frequently used for pressure vessels, tanks and heat-exchanger shell connections.

Provides procedures to calculate local flexibility components such as nozzle stiffness according to WRC 297, API 650 and PD 5500 based on shell and nozzle geometry.

Many manufacturers specify allowable loads for their equipment nozzles, which can be input as user allowable loads in CAEPIPE. CAEPIPE compares computed piping loads against these limits.
