(54) Title: ARRANGEMENT FOR THE CLEANING OF A PIPE SEPARATOR a) During pigging -2 \ /5 - 4 14 14 14 14 b) During operation (57) Abstract: Device or arrangement for cleaning a pipe separator (1) where the separator body (2) consists of an extended, tubular body with an inlet (4) and an outlet (5) having essentially the same diameter as the separator body. At the outlet, there's a bend or a loop (3) designed to maintain a fluid level in the separator. Just before the bend, there's an outlet (6) with an outlet pipe (9) for fluid, e.g. water, from the separator. Sand or other particulate materials introduced into the outlet (6) are returned, using a pump (7) arranged on the outlet pipe (9) , together with fluid from the outlet, to the separator after the bend (3) by means of reversal with a valve (8) via a return pipe (11) ; in connection with the outlet (6), there's a flushing device comprising a pipe loop (12) connected to the outlet pipe (9) for the return of fluid from the outlet to the nozzles (14) arranged in the outlet, designed to flush in direction downstream of the outlet, any particles having accumulated in the outlet chamber.
