A connector and tubing combination includes a tubing segment with an end piece, such as a tubing flange. The tubing flange can be secured within the connector by an outer sleeve and an inner sleeve of the connector. Both of the inner sleeve and the outer sleeve are located outside of the tubing flange and the tubing segment. In addition, the inner sleeve, outer sleeve and the tubing flange are mechanically connected.

The present invention relates to a subsea fluid flow tubular connection system with an inboard hub in fluid connection with piping of a sub sea hydrocarbon exploration or production system and an outboard hub. The sub sea fluid flow tubular connection system comprise a tubular saver sub with an inboard hub connecting portion in sealing contact with the inboard hub at a first end and an outboard hub connecting portion in sealing contact with the outboard hub at a second end. A method of installing and exchanging such a tubular saver sub is also disclosed.

A clamping system to connect a first and a second tube whose facing ends have protruding clamping surfaces is provided. The system comprises a collar comprising a belt able to be clamped around the clamping surfaces. The belt has a first and a second flank between which an internal recess able to receive the clamping surfaces is delimited. The collar carries an outer retaining clip comprising a retaining segment located on the side of the first flank and a first and a second link return linking respectively the retaining segment to a first and a second retaining member located on the side of the second flank. The collar is retained axially between the retaining segment and the first and second retaining members. The retaining segment is able to be elastically deformed to allow the insertion of the end of the tube and to retain it pre-mounted in the collar.

A fluid conduit connector system includes a first body having a neck extending from a first side, an opening in the neck, and a bore extending from the opening. The fluid conduit connector system further includes a second body having second and third sides, an opening in the second side, a bore extending from the opening, and an array of holes positioned around the bore and extending from the second side to the third side. Upon assembly, the bore of the first body is aligned with the bore of the second body, the second side of the second body is disposed adjacent to the neck, a tension flange is disposed around the neck, and a plurality of connection rods is coupled to the tension flange, each connection rod disposed in a corresponding hole of the array of holes and extending out of the third side of the second body.

A fluid conduit connector includes a monolithic body having a first opening at a first side and a second opening at a second side. A throughbore extends from the first opening to the second opening. A first array of holes in the first side is positioned around the first opening, each hole of the first array of holes terminating within the body. A second array of holes in the first side is positioned around the first array of holes, each hole of the second array of holes extending through the body to the second side.

An automated nursing robot is disclosed, including a main body unit, a wastewater bucket, a clean water bucket, a water injection and wastewater discharge unit for discharging and flushing the wastewater bucket and adding water into the clean water bucket, a mobile base disposed under the wastewater bucket and clean water bucket for carrying both to move between the main body unit and the water injection and wastewater discharge unit, and a connecting side plate arranged on one side of the mobile base. The main body unit and the water injection and wastewater discharge unit are each equipped with a positioning and fixing plate. Each positioning and fixing plate is provided with a pipe joint A, and the connecting side plate is correspondingly provided with a pipe joint B, and the pipe joint A and the pipe joint B are mutually attracted and connected by a magnetic attraction assembly.

Apparatus for hydrostatic testing of items having a flanged opening, such as flanged pipe sections, which apparatus contains a actuator having a actuator shaft attached to a blind flange, which actuator can be powered from a power source on a remotely operated vehicle, which items include those items located on land as well as subsea. Also provided is a remotely operated vehicle having a power source such as a hydraulic system that is used to operate the actuator on the hydrostatic testing apparatus.

A pipe flange is leveled for welding by using stainless steel using ball bearings attached to a U-shaped spring-loaded wire so a fitter is able to level a flange for welding while the wire supports a level. The ball bearings are part of a first leveling unit and a second leveling unit which comprise a flange leveling system. The spring acts to bias a first leg and a second leg of the leveling units such that the distal ends of both legs are biased toward each other. The ball bearings are axially co-linear with each other and are sized to be seated in bolt holes defined in the first and second sides of the pipe flange. A related process is also disclosed wherein the flange is adjusted until the associated flange holes on the first and second sides of the pipe flange are level with each other.

A pipe coupling assembly (200) for use with a seal (16) for sealing end portions of pipe elements (34), including: first and second coupling segments (10), each including a curved portion (12) having an inner surface (14) shaped to define an annular channel and shaped and sized to receive the seal therein. A fastening lug member (18) extends from the curved portion, the fastening lugs of the first and second coupling segments at least partially overlap when the fastening lug members are drawn towards each other. At least one restrainer (30) extending from an end (58) of the fastening lug member and in continuation with the inner surface of the curved portion of at least one of the coupling segments, inhibits trapping of the seal between the fastening lug members when the fastening lug members are drawn toward each other. Other embodiments are also described.

The embodiments of the present disclosure provide a detachable anti-vibration sealing protection device for a pipe flange. The protection device includes a casing, wherein left and right end surfaces of the casing have through holes for the pipeline to pass through, and the casing has an accommodation cavity for placing the flange; a first shock absorption assembly for radial shock absorption of the flange; and a second shock absorption assembly which is installed in a one-to-one correspondence with the flange and is configured for axial shock absorption of the corresponding flange. The first shock absorption assembly and the second shock absorption assembly are installed in the accommodation cavity.
