would contact conduit 40 at two points 180 degrees from each other the two point contact occurs only if the angular bend exceeds the selected limited once the two point contact is made the stiffness of housing 39 will be added to the stiffness of the conduit 40 between lower standoff plate 53 and upper standoff plate 41 for any additional bending to occur housing 39 must also bend this creates additional stiffness to avoid exceeding the yield strength of conduit 40 in that area gaps 59 are sized so that the acceptable limit of bending is safely before the yield strength of the conduit 40 is reached preferably about 2 3 of the yield strength this yield strength is the same as the yield strength of production tubing 25 a similar event occurs in the intermediate segment 33 and lower segment 35 excessive angular bending of conduit 40 will cause it to be contacted on two points 180 degrees apart from each other at the holes 67 89 and 95 this applies a bending force to intermediate housing 53 and to lower housing 91 to provide additional stiffness to withstand excessive bending no bending forces will be applied to housings 39 63 and 91 unless the acceptable limits.
