Abstract

An elbow junction is made up in two halves (3) and (4) split longitudinally and jointed by lapping and seaming the edges, (5a), (5b), (6a), (6b), inside on the straight ends of the elbow, outside on the elbow curve itself. The elbow is assembled into the pipework by sliding straight ends inside adjacent pipes up to the shoulders (9) pressed into the elbow. Junctions may be made from steel sheet and light alloys and surfaces may be protected against corrosion by pretreatment by galvanising or lacquering. Strong and smooth gas tight joints are formed and the construction method is suitable for complicated junctions.
