Thank you all for your response. As some of you suggested, we're going to follow the common-sense approach. It's not our spool fabrication. But we're going to own it after it leaves our shop. The end owner has an army of engineers that will be able to bog us down with questions and requests...
Good day;
This question has come up a few times in my world, and I'm hoping someone can point me in the right direction. I'm sure we've all seen pipe spools where someone has cheated while installing a slip on flange. The flange is "kicked" a bit to change the direction of a pipe. I've seen...
Good points. I have a similar concern. We are currently developing a procedure to blow from every high point vent and opening each low point drain. We are anticipating this will take two to three days to accomplish.
Yes it is initial hydro. I don't think the AI would have a problem with...
The client specification is for a dewpoint of -40C. We are considering a trailer mounted unit. However, I thought it was coming with a desiccant dryer.... I will contact the vendor again to confirm.
I will have to investigate the turbine option. I'm not sure if our client will allow it or...
Good day;
We are in the process of preparing for hydrotesting some OTSG units. The client will not be using them for quite some time after hydrotesting. The AI wants to see a procedure for drying the waterside of the tubes before we button everything up. Our intention is to use an oil free...
Hi everybody, thanks very much for all your input. I think I have it sorted out now.
racookpe1978: we are required by contract to heat the vessels for the refractory subcontractor. We are anticipating outdoor ambient temperature anywhere from -15 to +5C. We are required to maintain vessel...
Hello everybody;
I'm hoping you guys can help me with a little problem I'm having. I'm trying to determine the heating requirements for a construction site. The space consists of a temporary scaffold enclosed with insulated construction tarps. We are going to use Herman Nelson industrial...
One other thing I was going to add but hit "submit post" too quick. The way of calculating corroded wall thickness as suggested by my QA inspector is basically the same as what you would do if you were using a piping code such as b31.3. I'm just not sure if this is acceptable for ASME section...
I've been asked to design a compressed air receiver. The tradesmen that will fabricate it want to use threaded half couplings for the nozzles. When I did my calculations, I used the "G" dimension from ASME 16.11, deducted the corrosion allowance, and then deducted the thread allowance to get...
2", CL150, carbon steel slip on flange. Pipe is sched 40. It is for compressed air, and the pipe will be burried. Total length of underground pipe is 120 feet. They've asked us to supply the spools in 40' lengths, flanged ends.
We're still trying to drag a few more details out of the client.
Hello;
A client of ours has specified compressed air piping be galvanized post fabrication. The spec also calls for flanged connections. Any idea what we'll have to do to the flange after galvanizing? We are going to oversize the bolt holes slightly, and are thinking we'll have to machine the...
