Dear all, We are doin a calculation in which we have to take the wheel loads of different types of vehicles, viz. pick up truck, a 2t forklift, maintainance vehicle, truck and a 60t crane with outriggers. Can anyone please tell me where I can get these values or if you have any knowledge about...

Dear All, Thank you very much for sharing your ideas, and it certainly has enlightened me. I am extending my sincere gratitude and thanks to all. We have finally arrived in a satisfactory solution. I am sure you guys have heard abt Westergaards equation. We reversed the calculation to find the...

Dear All, 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 some idea about this please help me. kindly Enlightenme

Dear Ron, As far I know the polyethelene sheet is provided inorder to provide a vapour barrier. Rgrds Enlightenme

Dear all Thank you guys for helping me out, now i ve got a direction and thank you all for sharing it with me, And for your info have you seen the drawing i have uploaded among this post. I think that will give you a more clear cut idea abt the pavement details and its thickness. Please feel...

Dear Ron, The problem is that this is an existing facility. The scope is to determine the maximum allowed axial load on the flexible and rigid pavements. Even though we can suggest them modifications to existing facilities, the basic aim of this project is to determine maximum allowable axial...

Hello, This is a refinery area and the main traffic here will be cranes( ranging from 60 to 200 Tonne, maintanence vehicles, forklifts etc doin works inside the process areas). The details of the pavement I am attaching below. According to their refinery Civil specification on the lightduty...

Dear Freinds, I am a mechanical engg. (pipeline) have been asked to calculate the safe loads or maximum bearing loads (for different vehicle axle loads) on the pavements (Rigid pavings and Flexible Pavings) inside the process areas of a refinery. The pavements has been classified into light...

Hii all, We are talking abt interconnecting Mogas( at oper. press 6.4 barg and LPG with oper. press. 19.5 barg.) We had Design Review yesterday and the client have decided to scrap this interconnection because we told them its not feasible. But I just wanted to know if such a connection can be...

Dear all, I am doing a project in which we are inter connecting lines by providing hot tappings. There is a total no of 4 flow lines going parrellel to each other.(in the order- 1 gas line and 1 liquid line then 1 gas line and followed by a liquid line) And we are connecting the liquid line to...

Hii Dhengr, Yes there have been a slight improvement. Our civil guys have managed to determine the bearing load on the paved and unpaved areas. So that we will be able to determine the maximum allowed wheel load on the pavement. We will take this value at a particular depth( min depth) and give...

Dear Dhengr your reply has given me an insight regarding this. Our project deadline is nearing and after a meeting today with the clients they told us to give the following things. 1. The bearing capacities of the paved areas. (Light Duty paving & Heavy duty paving included, 150mm/300mm...

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...
