FLAME COATING MACHINE AND METHOD
A flame coating machine for coating field joints of a pipeline has a flame spray system having two flame spray units configured for heating and/or coating with a thermoplastic polymer an annular junction portion and two annular end portions of an existing coating delimiting the annular junction portion; a control system having two temperature sensors configured for acquiring temperature values along the surface collectively defined by the annular junction portion and the annular end portions, and a control unit configured for actuating the flame spray unit in a polymer flame spraying mode or in a flame heating mode as a function of the detected temperature values and at least one threshold value.
Tape Winding Apparatus and Method
A tape winding apparatus (1) for winding a tape around a cutback between two factory coated, welded pipes to form a field joint coating, the apparatus comprising a housing (2) having first and second ends and adapted to be mounted over or around the cutback, a tape cassette (62) rotatably mounted within the housing and means (120, 44, 80) for linearly driving the cassette through the housing from a first position adjacent a first end of the housing to a second position adjacent the second end of the housing, a heat source (70) mounted on the cassette for directing heat towards one end of the cutback and the tape as it is wound onto the pipe, and further comprising an additional heat source (150) mounted within the housing adjacent the second end of the housing for directing heat towards the other end of the cutback.
CONNECTOR FOR PIPELINES AND METHOD TO CONNECT THE CONNECTOR TO A PIPELINE
A connector for a pipeline, in particular for conveying hydrocarbons, extends along a longitudinal axis and has a gripping portion configured to be fitted around and clamped to the outer face; a sleeve portion, which is mounted in sliding manner to the gripping portion; a metal front gasket configured to be placed between the front end face and a face of the sleeve portion; and linear actuators connected with the gripping portion and the sleeve portion to axially compress the metal front gasket between the front end face of the pipeline and the face of the sleeve portion.
Method for coating a pipeline field joint
The present invention relates to a method of coating a pipeline field joint comprising the steps of (a) applying a layer of a coating material composition comprising (i) a propylene polymer and (ii) a substantially linear ethylene copolymer, a linear ethylene copolymer, or mixtures thereof, to the uncoated region of the field joint, preferably the coating is applied by injection molding.
Joint restraint device
A gland assembly includes a gland including an annular ring defining a fastener hole; and a joint restraint assembly comprising a restraint base, the restraint base attached to the annular ring; and a cover including a cover portion removably attached to the restraint base; and a bolt stop portion covering the fastener hole, the bolt stop portion extending laterally outward from the cover portion.
DETACHABLE ANTI-VIBRATION SEALING PROTECTION DEVICE FOR PIPE FLANGE
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.
Tubing connector for decreased contamination
A protective guard for a medical tubing connector includes a ring, at least one flexible member attached at a first end to the ring and having a second end, and a base attached to the second end of the at least one flexible member. The ring is configured to fit over a first connection member of the medical tubing connector, while the base is configured to fit over a second connection member of the medical tubing connector. When coupled with the medical tubing connector, the protective guard helps prevent a user from touching the medical tubing connector.
Coupling assembly and protective ring therefor
A coupling assembly includes a coupling, a protective ring and two tubulars, the coupling of generally cylindrical shape with a channel therethrough, the coupling having at least one internal thread and two coupling ends and a pin end of at least one of the two tubulars having an external thread for threaded mating therewith so that the coupling assembly provides a connection between the two tubulars, the protective ring including a ring body for positioning adjacent an interior wall of the coupling between the two ends thereof, the ring body being generally cylindrical and having a ring channel therethrough, the protective ring includes one of a tongue and groove and at least one of the ends of at least one of the two tubulars having the other of a tongue and groove.
Prefabricated part with a concrete body
A prefabricated part comprises a concrete body that has the form of a pipe section with two pipe ends and a pipe inner side. The pipe inner side is lined at least in some areas by a lining made of plastic material connected to the concrete body, and at least one of the pipe ends is covered at least in some areas by a molded part made of plastic material connected to the concrete body. At least the pipe end, which is covered at least in some areas, has a connecting joint in order to connect the pipe end to a pipe end of a further prefabricated part. The lining consists of a thermoplastic material and the molded part consists of a thermosetting plastic. The lining and the molded part are connected to each other in a sealed manner.
Reducing the risk of corrosion in pipelines
A tubular includes a carbon steel main body defining a first flow passage. The carbon steel main body includes a first end and a second end. The carbon steel main body includes a beveled edge at the first end of the carbon steel main body. A corrosion resistant pup defines a second flow passage in-line with the first flow passage. The corrosion resistant pup includes a substantially same inner diameter and outer diameter as the carbon steel main body. The corrosion resistant pup includes a first end and a second end. The corrosion resistant pup includes a first beveled edge at the first end. The corrosion resistant pup is connected to the carbon steel main body by a weld along the beveled edge of the carbon steel main body and the beveled edge of the corrosion resistant pup.
