JStephen, Thanks. Will try. Arto, Thanks. Basically it would take time before I could get the book as part of my additional reference. Can you provide advanced scanned copy at the moment? aobautista@bhpi.com.ph

We have been using swaged tubes for our small capacity bi-drum boilers. Based on experienced by using swaged tubes we can decrease the drum thickness due to increase in ligament efficiency, Take note we need to consider also the other drum holes configurations whichever is the least ligament...

I have been asked to look into designing a circular flat endplte with stiffeners havin a diameter of 3m~5m for storage (water crude oil, chemicals) horizontal tank. ASME Sec. VIII Div. I has discussed it but without stiffeners, so the resulting thickness is too big even atmospheric condition...

I'm new to VBA. I would like to automate in autocad the generation of either close or open polygon then if it is closed polygon it would also calculate the area. The input data should be the angle and length for each line in the polygon. The input data maybe also extracted automatically from a...

Doru, Check UCS-56 if you can weld without mandatory PWHT. AOBJR

SexSeaEngineer, There are two methods to calculate the boiler efficiency. You may refer to ASME PTC 4-1998. AOBJR
