Factory and industrial management . , but instead, will push out the sup-ports and strain connections. There are sometimes situations inwhich no other expansion joint can readily be used. The one then STEAM PIPING POR IXDUSTRIAL PLANTS. 75 used should be provided with safety tie-rods, so that should theanchorages fail the line cannot blow apart, and the packing had bestbe metallic. The anchorages must be figured strong enough not only to over-come the friction in stuffing box and pipe hangers, but also for astress equal to the steam pressure multiplied by the unbalanced areaof the joint. The steam line must be supported close to the slipjoint, as a very slight sag in the pipe will cause it to bind. The loca-tion of the expansion joint must be determined by the profile of thesurface over which the steam line is carried, the amount of expan-sion, and the type of joint used. Long lines may require severaljoints, since every sharp change in direction will require provisionfor expansion. I-EYE BOLT Z^^^ELAT CORE TO SU/TNAIL-.
