发明名称 Latch-type tubing protector having C-shaped clamping members, a minimized running profile and a large holding force
摘要 Apparatus for protecting tool joints and injection or control tubing of production tubing strings employed in the production of oil and gas is disclosed, where the protector has a minimized running profile and includes two C-shaped clamping members designed to be forced onto a pipe string above and below a joint with sufficient holding force to allow protector assembly without the need to hold the ends in place during the assembly process. The protector also includes beveled leading and trailing edges to further minimize the likelihood that the protector will hang up during production string insertion and withdrawal.
