    摘要: Le procédé est destiné au calibrage des extrémités d'éléments métalliques tubulaires (4, 5) destinés à être soudés bout à bout.
    On engage à force ces extrémités sur une forme de calibrage (9) adaptée pour réaliser sur ces extrémités, un évasement dont le diamètre intérieur maximal est au meins égal à celui correspondant à la tolérance maximale admise en fabrication, augmentée éventuellement de la tolérance sur l'ovalisation et celle due au retrait de refroidissement et de soudage.
    Utilisation notamment pour calibrer des tubes en acier.

    摘要: Provided are a magnetic rotating arc joining method that can suppress occurrence of joint defects with a simple configuration and a joint unit in which joint defects are suppressed. A joint unit (10) includes a first metal pipe (21), a second metal pipe (22), and a joint portion (a region including a joint interface (11)) at which the end faces of the first and second metal pipes are joined to each other. At the joint portion, an outer circumferential bead portion protruding toward the outer circumference side and an inner circumferential bead portion (13) protruding toward the inner circumference side are formed. The difference between the width of the outer circumferential bead portion (the width L1 of a grinding portion (12)) and the width L2 of the inner circumferential bead portion (13) in a direction from the first metal pipe (21) toward the second metal pipe (22) is equal to or smaller than 40% with respect to the average value of the width L1 of the outer circumferential bead portion and the width L2 of the inner circumferential bead portion (13).

    摘要: A temperature-adjustable plastic water pipe connecting structure includes two vertical pipes (1) and a horizontal pipe (2). The vertical pipe (1) has a first threaded portion (101) formed on a top portion of the vertical pipe, a second threaded portion (102) formed on a bottom portion of the vertical pipe (1), and a bump (103) formed on a peripheral wall of the pipe and having an outlet (104). The horizontal pipe (2) has two ends and a connecting seat (202; 203; 204) mounted on the horizontal pipe (2). The two ends are respectively mounted into the outlets (104) of the two vertical pipes (1). The present invention has the advantages of a simplified connecting structure facilitating assembly of the temperature-adjustable plastic water pipe, significantly reducing the parts of the temperature-adjustable plastic water pipe and cost in production, and simplifying the manufacture.
