Abstract

See full text

A scale-dampening or scale-inhibiting device is at a radial restriction in a pipeline. A helical flow guide is arranged in a pipeline portion upstream of the restriction. The flow guide projects radially inwards from a pipe wall and has a longitudinal direction slanted relative to the center axis of the pipeline. A method is for dampening or inhibiting scaling in a dead zone of a fluid flow downstream of a restriction in a pipeline.
