    摘要： A multi-layered heat resistant metal tube is disclosed. This tube has excellent anti-coking characteristics and is suitable for use under the conditions where carbon tends to deposit and accumulate thereon due to contacting with hydrocarbons at a high temperature. The tube is made by forming weld-mounted overlaid layer of a Cr-Ni-Mo alloy by building-up welding over the inner surface and/or the outer surface of a substrate tube made of a heat resistant metal. The Cr-Ni-Mo alloy consists essentially of, by weight %, Cr: 36-49 wt%, Ni: 35-63 wt% and Mo: 0.5-5 wt%. Building-up welding is preferably carried out by PPW (Plasma Powder Welding) in which the filler metal is supplied in the form of powder.

    摘要： A metal pipe inner surface weld-mounting apparatus is constituted by an arm (3), a horizontal torch (4), a mirror (21; 80), and a camera (24). The arm (3) has a supported base end portion, which is horizontally extended. The horizontal torch (4) is attached to a leading end portion of the arm. The weld-mounting is performed on an inner surface portion of a metal pipe (w) supported rotatably around a horizontally extending axis (14) while at least one of the metal pipe (w) and the horizontal torch (4) is moved in a direction of the axis. The mirror (21; 80) is attached to the leading end portion of the arm. The camera (24), is disposed in a position separated from the mirror for picking up an image (25), of weld-mounting beads (23), in a neighbourhood of arc light (22), of the horizontal torch (4) through the mirror (21; 80). Preferably, a monitoring device (26; 70) monitors a condition of the weld-mounting.

    摘要： A metal pipe inner surface weld-mounting apparatus is constituted by an arm (3), a horizontal torch (4), a mirror (21;80), and a camera (24). The arm (3) has a supported base end portion, which is horizontally extended. The horizontal torch (4) is attached to a leading end portion of the arm. The weld-mounting is performed on an inner surface portion of a metal pipe (w) supported rotatably around a horizontally extending axis (14) while at least one of the metal pipe (w) and the horizontal torch (4) is moved in a direction of the axis. The mirror (21;80) is attached to the leading end portion of the arm. The camera (24), is disposed in a position separated from the mirror for picking up an image (25), of weld-mounting beads (23), in a neighbourhood of arc light (22), of the horizontal torch (4) through the mirror (21;80). Preferably, a monitoring device (26;70) monitors a condition of the weld-mounting.
