NOTE
Information and date contained in these charts as taken from ASTM Specifications No. B88. Federal Specification WW-T-799, and various Copper Tube Mill chart standards.
T Based upon 150 F. with an allowable stress of 9000 p.s.l.
* Bursting pressures.ard calculated from the following Formula for thin, hollow, cylinders under tension :
|
Where P = 2ts/D |
P = Bursting pressure, lb. Per sq. in |
* Based upon 150 F, with as allowable stress of 5100 p.s.l.
o Rate internal pressures for copper water tube based on the strength of the tube alone and applicable to systems using suitable mechanical. Joints. (pounds per sq. inch)
