Requirements to Move Unpressured Pipe

This application is related to maximum movement (deflection) at the end of pipe with no pressure. The greater the deflection requires a larger distance of exposed pipe to minimize the strain on the pipe.

𝑆_𝑚𝑎𝑥 − Maximum Stress Allowed

𝑆𝑀𝑌𝑆 − Specific Minimum Yield Strength

𝑆_𝑀 − Section Modulus

𝐷 − Nominal Outside Diameter(in)

𝑡 − Nomnal Wall Thickness(in)

𝐼 − Moment of Inertial

𝐷 − Nominal Outside Diameter(in)

𝑡 − Nomnal Wall Thickness(in)

𝐿_𝑑 − Maximum Deflection at Pipe End(in)

𝑌 − Young′s Modulus of Elasticity(psia)

𝐿_𝑝 − Total Exposed Pipe Requirement(ft)

𝐿_𝑚𝑎𝑥 − Maximum Load at the Pipe End(lbs)
