ABSTRACT:
A two-part, ring-like, hook-on protector device provides a secure but easily removable mounting at spaced locations along heavy pipe or casing members that are normally stacked in a horizontal lengthwise extending relation for storage and shipment to oil and gas well drilling and operating locations. The device, of two-part, pivoted together construction and circular shape, is formed of tough elastomer material whose parts are of complementary interfitting construction devised to assure a substantially equally spaced, stacked relation between adjacent pipe members to both protect the members along their lengths as well as any threaded ends and collars. It has a maximum unitized strength and a space-retaining resistance to deformation with respect to radially applied forces thereon when several devices are mounted in a lengthwise spaced relation along a pipe member that is in a stacked relation with adjacent members. It employs two solid, stress-absorbing pivoted-together, semicircular pairs, halves or arms. At least one pair of adjacent ends of its arm parts are pivotally connected together and the other pair of adjacent ends have a separable connection to permit the parts to be opened as well as closed for easy latching-on mounting and unlatched removal from pipe members that are being stacked for storage and those that are being removed for usage.
