A garden hose has an inner tube for conveying water at domestic water pressure from a first coupler disposed at a first end of the inner tube to a second coupler disposed at a second end of the inner tube, the inner tube being waterproof and flexible, the first coupler adapted to threadedly connect to a conventional water faucet and the second coupler adapted to threadedly connect to a conventional garden appliance. The hose has a metal sheath disposed over the inner tube and extending from the first coupler to the second coupler, the flexible metal sheath having a first shoulder near the first coupler and a second shoulder near the second coupler, the metal sheath being flexible, and a fabric sheath disposed over the metal sheath and fixed to the metal sheath by a first constricting band disposed at the first shoulder and a second constricting band disposed at the second shoulder.

A machine for a drilling plant includes a base, an arm, and a tool which is carried by the arm. The tool has a receiver for a protective cap. The machine is operable to engage the protective cap and to remove or to install the protective cap from or on an end of a drilling tubular.

A system and a protector for protecting pipes is proposed, wherein the protector comprises a bumper portion made out of an elastomer and an engaging portion made out of a polymeric material.

A thread protector that has an external sleeve having threads disposed on an inner side to engage with pin threads disposed on a pin end of a tubular member. The thread protector also has a flange disposed on a first end of the external sleeve to engage with the pin end of the tubular member, the threads on the inner side of the external sleeve are disposed axially adjacent to the flange and radially adjacent to the end of the pin end of the tubular member. A method of protecting the pin threads of the pin ends of the tubular members. The method includes screwing the thread protector on the pin threads of the pin end of the tubular member.

On example provides a containment sleeve for a pressurized piping system including a main body comprising a pliable fabric extending in longitudinal and transverse directions. The main body includes an exterior major surface and an opposing interior major surface, first and second opposed transverse edges, first and second opposed longitudinal edges, and a number of pleats extending from the interior major surface, each pleat having opposing sides of the longitudinal pleat being sewn together with breakaway stitching at a base of the pleat at the interior major surface. A number of transversely extending straps disposed on the exterior major surface between the first and second longitudinal edges, the straps to secure the main body about a portion of the piping system with the interior major surface facing the piping system.

A robotic vehicle for moving above ground while fabricating a subsurface polymer layer to protect an underground structure is provided. The robotic vehicle includes: a body; a rotational member that contacts the ground and moves the body over the ground; a ripper assembly having a proximal end that moves with the body, and a distal end that moves underground at a fabrication depth in response to the movement of the proximal end while fabricating the polymer layer; a ground penetrating radar (GPR) that locates and measures a depth of the underground structure below the ground; and a computerized control system that controls the rotational member, the distal end of the ripper assembly, and the GPR to move the body over the located underground structure while tracking the location of the underground structure and fabricating the polymer layer at the fabrication depth and above the measured depth of the underground structure.

A pipe coupler having a function of covering a pipe. The pipe coupler includes a coupler main body having a hollow, a grip ring provided in the hollow and configured to fix the pipe so as to allow the pipe to be inserted thereinto and prevent the inserted pipe from coming out, and a packing member provided in the hollow, and configured to seal a gap between the coupler main body and the pipe when the pipe is inserted into the packing member. The packing member includes a pipe locking protrusion protruding inward from an inner surface of a lower end portion thereof so that a front end portion of the pipe inserted into the packing member is surrounded and covered. The pipe coupler can prevent a coating layer of a pipe from being peeled from a tip of the pipe.

Disclosed is a reinforced hose comprising a pressure sleeve concentrically installed over an outer surface of the hose tubing, either above or below the ferrule. An inner diameter of the pressure sleeve is larger than an outer diameter of the hose tubing and the first terminal end of the pressure sleeve is longitudinally aligned with the first open end of the hose tubing. The longitudinal length of the pressure sleeve is greater than that of the ferrule and extends beyond a proximal end of the ferrule. A first interference joint couples the outer surface of the hose tubing to an inner surface of the pressure sleeve, the first interference joint comprising a contact patch located between the second terminal end of the pressure sleeve and the proximal end of the ferrule.
