Abstract: Process for producing steel submarine pipes (1) intended for conveying corrosive fluids and especially water, comprising the steps in which: 1) the respective ends of at least two unitary pipe elements (2a-2d) are joined together, in a workshop on shore, by first welds (41) made of carbon steel, in order to form pipe strings (3a-3b), said first welds being protected by first liners (61); and 2) the respective ends of said strings (3a-3b) are joined together, offshore on a laying vessel (20), by corrosion-resistant second welds (42) made of stainless steel or a corrosion-resistant alloy, in order to form a said pipe, the ends (31, 32) of said strings each having a corrosion-resistant coating (5) made of said stainless steel or corrosion-resistant alloy, extending over the internal carbon steel surface of each said terminal unitary pipe element over a first length (l1) of at least 4 times, preferably 4 to 20 times, the wall thickness of the pipe.

Abstract: A flexible metal tube comprising parallel-corrugated metal corrugated tubing (1) and a metal weave (2) arranged thereabove receiving traction forces, in addition to at least one connection piece (3) for connection to at least one of the ends of the flexible tube and which engages with the end of the flexible tube by means of a bushing piece (4), being connected thereto by means of welding. Said flexible metal tube can be connected to the connection piece (3) in a tight and mechanically stable manner in a simple automated process such that a radial weld (9) which is closed on the peripheral surface thereof is formed at the level of an corrugated crest (6) of the corrugated tubing (1), preferably starting from the bushing piece (4) via the metal weave (2) leading to the corrugated tubing (1), and extends from the bushing piece (4) through the metal weave (2) into the corrugated crest (6) of the corrugated tubing (1).

Abstract: The invention relates to a method for producing an element (1) comprising coaxial pipes, including an inner pipe (1a), an outer pipe (1b) and a forged connector (2a, 2b) at each of the ends thereof, each connector consisting of at least a first inner arm (32) which is recessed (L1) in relation to a first outer arm (31). According to the invention, all of the circular welds between the inner pipe and the outer pipe and the connectors are made from the exterior of the pipes. The invention also relates to the coaxial pipe element (1) thus produced, which is characterised in that the inner pipe (1b) is subjected to a tensile stress.

Abstract: Die vorliegende Erfindung betrifft ein mehrschichtiges Kunststoffrohr (10) umfassend mindestens eine Kernschicht (11) und mindestens eine Deckschicht (12, 13), welche dazu bestimmt ist, bei Bedarf in einem Schälvorgang von der mindestens einen Kernschicht entfernt zu werden. Um das Entfernen der Deckschicht (12, 13) vor einem Schwcißvorgang zu erleichtern, ist erfindungsgemäß vorgesehen, dass mindestens eine Deckschicht wenigstens einen achsparallel ausgerichteten oder spiralförmig um die Rohrachse in Umfangsrichtung verlaufenden Sollbruchbereich (15) aufweist, der ein Abschälen der mindestens einen Deckschicht ermöglicht. Dieser Sollbruchbereich kann zum Beispiel durch eine Perforation oder Schwächung gebildet sein. Um den Beginn des Schälvorgangs zu vereinfachen, ist optional ein Trennelement (14) vorhanden, an dem angegriffen werden kann, um die Deckschicht (12, 13) einzureißen.

Abstract: A method for joining tubular elements made of stainless steel, an alloy thereof, aluminum or other equivalent metallic materials, particularly for providing coolant gas piping for refrigeration systems, comprising the steps of:
- deforming a first head portion (11a) of a first tubular element (11) so as to reduce its outside diameter to a size which allows its insertion in a second head portion (12a) of a second tubular element (12) to be joined to the first tubular element (11),
- inserting the first head portion (11a) in the second head portion (12a), so that a welding channel (15) is formed between the end (13) of the second head portion (12a) and the facing connecting portion (14) between the tubular body (11b) and the first head portion (11a) of the first tubular element (11a),
- performing a welding operation with the addition of material between the first element (11) and the second element (12) inside the welding channel (15).

Abstract: A conduit (100) comprising a plurality of conduit segments (112A-112C) each having a body (120A-120C) and a segment lining (136A-136C) made of a lining material. Each body includes a joint face (132A-132C) having secured thereto a portion (140A-140C) of the corresponding segment lining. A monolithic lining (108) is formed from the segment linings by abutting the conduit segments with one another so that the joint faces face one another and the portions of the segment linings contact one another. The portions of the lining on the joint faces are heated to a temperature above the melting point of the lining material so that they fuse with one another so as to form a fusion (148A, 148B) located between the joint faces.
