Question:
When analyzing a model in AutoPIPE Vessel the following warning number was reported.
1011 Allowable compressive stress [EN 13445-3 16.14.8] : Using fabrication tolerance quality class C and taking factor ψ = 0.75 is a conservative assumption for vessels that satisfy the manufacturing tolerance requirements of EN 13445-4, Clause 6.
Why and how to avoid it?
Answer:
This warning message indicates that AutoPIPE Vessel considers the fabrication tolerance quality class C and taking factor ψ = 0.75.
See below code reference,
Note:
1. This is conservative assumption for vessels that satisfy the manufacturing tolerance requirements of EN 13445-4, Clause 6.
2. This fabrication tolerance quality class can not be changed.
