1Theoretical Collapse pressure based on max OD, minimum wall thickness, and minimum yield strength. |
2Theoretical Burst pressure based on max OD, minimum wall thickness, and minimum tensile strength. |
3Theoretical working pressure utilizes a 1.33 S.F. from theoretical Yield Point |
Working Temperature: 350°F |
Test pressures above 25ksi are available upon request. |
E - "Enhanced" properties increased yield strengths, coils without orbital welds at final size. |
Features
