<p>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 spaceretaining 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. It is shown as having a full body or thickness throughout along its extent, including its joints, and is resilient throughout and fully reusable. Its two arm parts are shown as of a balanced substantially equal extent and through-extending latch pins serve at one joint to pivotally swingable connect its two arm parts and, at the other joint, serve as connecting latching means for opening and closing the arm parts about a pipe member.</p> |
