摘要： The present invention relates to a pipeline assembly and a manufacturing method therefore. The pipeline assembly (10, 20, 30, 40) comprises one or more tubular bodies (11, 21, 31, 41, 42) formed of one or more arc-shaped profile members (12, 22, 32, 33, 43, 44). Each arc-shaped profile member (12, 22, 32, 33, 43, 44) includes a tongue (12a, 22a, 32a, 33a) at one first edge and a groove (12b, 22b, 32b, 33b) at another first edge, wherein the first edges are opposite to one another.

摘要： Electric resistance welded steel pipe securing the high strength and high toughness demanded from oil well pipe in recent years. The metal structure in a region having a width of 0.5 mm in both the thickness directions from a reference point, when using a point defined as a point ¼ of the thickness in the thickness direction from the surface in the base material part of the steel pipe as the reference point, consists of polygonal ferrite: 10 area % or less and a balance: bainitic ferrite. The thickness is 15 mm or more.

摘要： A chemical conversion-treated steel pipe has a chemical conversion treatment film on a plated layer on a steel sheet. The plated layer is configured from a zinc alloy comprising 0.05-60 mass % aluminum and 0.1-10.0 mass % magnesium. The chemical conversion treatment film contains a fluorine resin, a base resin, metal flakes and a chemical conversion treatment component. The base resin is one or more selected from a group consisting of polyurethane, polyester, acrylic resins, epoxy resins and polyolefin. The content of fluorine resin with respect to the total amount of fluorine resin and base resin is at least 3.0 mass % calculated as fluorine atoms. The content of the base resin with respect to 100 parts by mass of the fluorine resin is at least 10 parts by mass. The content of metal flakes in the chemical conversion treatment film is greater than 20 mass % up to and including 60 mass %.

摘要： A method for producing a tubular member from a metal sheet may include applying an adhesive layer to at least one joining section of at least two associated joining sections of the metal sheet, forming the metal sheet into a tubular member such that the at least two associated joining sections may be arranged on one another, and heating the adhesive layer by rolling a first roll over the metal sheet.

摘要： A flanged duct blank has a male part defined by lead notches formed at each side of a leading end and has a female part defined by trail notches formed at each side of a trailing end. The male part includes a lock tab. The female part includes a leg part and a Z-bend. The Z-bend includes a leg part and a gap. The duct blank is repeatedly clamped and bent by a pivoting wiper to form a duct portion. The pivoting wiper includes a clench tool that has a retractable rib and a retractable roller. With the lock tab inserted into the Z-bend and the retractable rib engaged with the Z-bend, the retractable roller clenches the leg part over the lock tab to lock the male and female parts together in a duct seam.

摘要： An expandable tube portion including slots arranged in a staggered fashion is expanded. When the expandable tube portion is expanded, the individual slots open to a cut end portion of the expandable tube portion are transformed to open in V-shape while the whole body of the expandable tube portion is transformed to a lattice configuration. Hence, the tube expansion only need to apply a working force required to bend intersections of the lattice configuration, resulting in the reduction of the working force for tube expansion. As a result, the working force for tube expansion does not open a butt connection portion of a subject matter, negating the need for previously weld bonding the butt connection portion of the subject matter.
摘要翻译： 包括以交错方式布置的狭缝的可扩张管部分被扩大。 当可膨胀管部分膨胀时，向可扩张管部分的切割端部开口的各个槽变形为V形开口，而可扩张管部分的整个体转变为格子状。 因此，管膨胀仅需要施加弯曲格子结构的交点所需的加工力，导致管膨胀的作用力的降低。 结果，用于管膨胀的工作力不会打开主体的对接连接部分，从而不需要预先焊接接合主体的对接连接部分。

摘要： A multi-walled pipe and a method for its manufacture involves a steel sheet forming a steel source layer to which a nickel source layer is applied on at least one or both sides. A solder source layer is applied to the one nickel source layer, or one of the two, or both, nickel source layers. The multi-walled pipe is formed from a strip of the coated metal sheet, by means of rolling. The walls of the pipe are soldered by means of heating. In one form, the heating takes place by radiation. In another, it takes place by induction.
