Could any one tell me the pressure rating of 4" SCH 5 Stainless steel pipe? Or give me a link to a chart, I haven't been able to find it on the Internet. I plan on building a large steam rocket and I'm hoping that 4" SCH 5 stainless steel can hold at least 500 PSI at around 400 degrees fahrenheit. I want to use SCH 5 because it is relatively light and less expensive than SCH 40.

Any help would be appreciated.

I don't think SCH 5 would be a good idea..

But that's just my thinking.... It seems to me like it wouldnt be a good idea.

Only thing I could find was that 3'' SCH 10 stainless steel pipe can hold 2,100 PSI and its max temp rating is 800F. Also, wouldnt 4'' pipe be to heavy for a rocket?

unless its a large rocket, give some more detail as to what you are exactly trying to accomplish.

Well first I am going to make some small prototype engines out of 3/4" copper pipe. After finding the best design I am going to make a larger one out of 2" SCH 5 stainless steel about 4' long and see what kind of height I get from that, if it is pretty good my ultimate goal is to build a rocket with a 4" diameter motor but I don't know what would be a good pressure vessel. I am just considering 4" SCH 5 Stainless steel, the project may never even get to this part since it depends on the steps leading up to it but I was just wondering about the pipe.

Sorry i could only find up to a 2" chart
