The Physical Properties for Drill Pipe body

Grade	Yield Strength				Tensile Strength		Elongation 2 in. (50.8mm)
	Min.		Max.		Min.		%
	PSI	MPa	PSI	MPa	PSI	MPA
E-75	75000	517	105000	724	100000	689	See Note Below
X-95	95000	655	125000	862	105000	724
G-105	105000	724	135000	931	115000	793
S-135	135000	931	165000	1138	145000	1000

Note: The minimum elogation is calculated with the formula below? e=625000A0.2/U0.9
Where: e-minimum elongation(%) when standard distance is 2 in. (50.8mm)
A-cross-sectional area of tensile strength (Unit: Sq.in.)
U-specified tensile strength (Unit: psi)
