PIPE SPREADER BAR DESIGN WITH END CAPS v.02

COMPANY: PROJECT:
ITEM NUMBER:

	kips	Total load, includes the weight of vessel, trays, insulation, piping, rigging, etc
	deg	Angle of the left sling. Use the smallest sling angle if CG is off center
		Number of parts of lift sling at each end of bar, ie, a doubled sling is two parts
	in	Horizontal distance, bearing to bearing on a duplex crane hook
	in	Horizontal distance from the CG to the centerline of the left vertical lift sling
	in	Horizontal distance from the CG to the centerline of the right vertical lift sling

SELECT: Lift sling type, diameter, and SWL. Program will prompt for larger capacity sling if required

SELECT: Pipe diameter and schedule

	lbs/ft	Weight per foot of pipe
	in	Radius of gyration, r
	in^2	Cross-sectional area of metal, A
	in^3	Section Modulus, Sx
	in^4	Moment of inertia, Ix
	ksi	Yield stress (Fy)
		Impact Factor, I.F., Recommend using a minimum of 1.8

Result:

OUTPUT:

in	Length of the left lift sling, centerline of the bar to bearing on the hook
in	Length of the right lift sling, centerline of the bar to bearing on the hook
in	Length of the left support sling, centerline of lug hole to bearing on hook
in	Length of the right support sling, centerline of lug hole to bearing on hook
in	Rigging height, centerline of the bar to bearing on hook
deg	Angle of the right sling
kips	Tension in the left lift sling above the bar
kips	Tension in the right lift sling above the bar
kips	Total lift sling capacity at each end of the bar, ie, number of parts*SWL
kips	Maximum tension in the support slings
kips	Compression in the bar due to the influence of the lift slings
kip-in	Moment due to compression force times the eccentricity, left end of bar
kip-in	Moment due to compression force times the eccentricity, right end of bar
kip-in	Moment due to the deflection of the bar due to self weight
kip-in	Moment due to the self weight of the bar
kip-in	Net bending moment, left end of bar	A minus value indicates the bar
kip-in	Net bending moment, right end of bar	is being bowed up at the center
ksi	Bending stress, actual, fb, left end of bar
ksi	Bending stress, actual, fb, right end of bar
ksi	Bending stress, allowable, Fb
ksi	Axial stress, actual , fa
ksi	Axial stress, allowable, Fa
	Combined stress check, must be less than 1.00. Includes impact factor IF
