Q1. I am doing the live load calcs of pipes for an entire refinery, coz a GRE pipe ruptured when crane passed above it. The problem is they now want to find the maximum allowed live load on all the pipe(includes CS pipes n CS sleeves ranging from OD 4" To 100"). I am proceeding as per API 1102, but it only considers HS 20-44 vehicle and its axle loads. How can I calculate Loads for cranes (200 T crawler crane included.)? And how can I generalise a safe load for a particular pipe since the surface area of cantact(wheel) varies with vehicle types. Can anyone pls help? Can anyone suggest a methodology?
Q2. The graphs in API 1102 only provides line size upto 42" OD? How do I get the values of Pipes of above 42"? It is clearly written in the specification Extrapolation is not recommended. If anyone has knowledge about this please help me!
