Hi @SHDW, welcome to the forum! 
Please check out How to get help on the Dynamo forums
It’s taken awhile to look at your question as it is not a simple request
When looking at a complex problem we can break it down into component tasks, something like this:
- Open excel file and extract data
- Get data and elements from Revit document to assist with task
- Format / manipulate data to be used in Dynamo / Revit
- Process data to create new elements, in this case pipes
- Manipulate new elements in the document, if required
The format of the Excel file is going to be important - here is an example
Here is a work in progress - unfortunately the Orchid node does not appear to be working
I have had to build python nodes to get pipe types and levels by name
