Calculation of the length of the short arm of the Z-shaped compensator
Z-shaped compensators are called sections of the pipeline with two branches in the same plane. They are used for self-compensation of thermal elongations in pipelines for any laying methods, regardless of diameter.
Calculation of the Z-shaped pipe compensator is performed to determine the dimensions of the Overall length (H) and the arm (L, P), at which the bending stress from the thermal deformation of the pipeline will not exceed the permissible value of 80 MPa.
This online program will calculate the bending stress at critical sections of the pipeline, with a Z-shaped compensator of specified dimensions.
The algorithm is taken from the methodology for calculating the Z-shaped compensator shown — Designer's handbook 'Designing heat networks' edited by A. A. Nikolaev.
