respectively fig2 b and 2d are plots of pipe stress versus longitudinal position of the tubular 90 along the slips 20 in a prior art spider and the spider 5 respectively fig2 a shows that an inclination angle 95 is the same for both the slips and the bowl fig2 b shows the resulting stress distribution along the length of the pipe in contact with the slips engineering calculations and finite element analysis show that the stress is concentrated on the lower section of the slips that are engaged with the tubular this stress concentration is caused by the combination of radial stress that is generated by the slips engaging the tubular with axial stresses produced by the weight of the string thus the stress distribution is non uniform and the stress increases towards a lower end of the tubular 90 fig2 c shows a design that more evenly distributes the stress distribution along the length of the tubular 90 in contact with the dies 20 c of the slips 20 each slip 20 has an inclination angle 95 s that is greater than an inclination angle 95 b of the bowl preferably the difference between slip angle 95 s and bowl angle 95 b is less than 1 degree more preferably less than one quarter of a degree and most preferably less than or equal to about one eighth of a degree this difference results in an upper portion of each of the dies 20 c contacting the tubular 90 before the rest of each of the dies as the weight of the tubular 90 is transferred to the spider 5 the.
