In the stress calculation report ope w＋t1＋p1＋h, what does H represent?
Thread Content
w is gravity, t is temperature. What is t1? It’s also temperature p is pressure. By the way, what is p1? What is h?
OPE stands for operating conditions; it refers to the state in which the system is in use. W represents the weight of the pipe under normal operating conditions, WIND denotes the wind load, D refers to the additional displacement of the pipe, T is the temperature, P is the pressure, and F represents the concentrated force/moment. H should refer to a spring. t1+p1 indicate the temperature and pressure under the first set of operating conditions; if there is a second set of conditions, namely t2+p2, it is possible to calculate the stress values at various points under each set of conditions.
