Abstract: A sleeve shaft includes an inlay. A fluid can flow through the sleeve shaft along an axial direction which is parallel to a main extension of the sleeve shaft. The inlay includes a first wall section and the inlay is inserted at least in part into the sleeve shaft such that the inlay together with a first area of an inner surface of the sleeve shaft encloses a volume domain, which volume domain is limited in the axial direction by a limiting element comprised by the inlay. The first area of the inner surface of the sleeve shaft is an inner surface of a first section of the sleeve shaft, the first section having an inner diameter which is larger than an inner diameter of a further section of the sleeve shaft that follows the first section in a direction antiparallel to the axial direction.

Abstract: An apparatus for forming glass tubes is provided. The apparatus includes a Danner-pipe, a heating device, and a heating chamber having the Danner-pipe and the heating device arranged therein. The Danner-pipe is inclined with respect to a horizontal plane by a Danner-angle. The heating device is inclined with respect to the horizontal plane by a heating-angle. The Danner-angle and/or the heating angle are in a range of 1° to 45°.

Abstract: An inlay for a sleeve shaft for collecting particles originating from a material of the sleeve shaft at least in part, at least one fluid being flowable through the sleeve shaft along an axial direction which is parallel to a main extension of the sleeve shaft, the inlay includes at least one first wall section and the inlay is inserted or insertable at least in part into the sleeve shaft such that at least one part of the first wall section has a radial distance from at least one first area of an inner surface of the sleeve shaft, and, hence, that the inlay together with the first area of the inner surface of the sleeve shaft encloses at least one volume domain, which volume domain is limited in the axial direction by a limiting element.

Abstract: A glass tube element having a hollow cylindrical section with a shell having an outer diameter is provided. A first ratio is a difference value to a mean value. The difference value is a difference of a minimal and maximal value of the outer diameter. The mean value is a mean of the minimal and maximal values. A sub-section having a start, an end, and a distance of 1 meter measured along a straight line from the start to the end and intersecting with a center axis of the sub-section at the start and the end. The sub-section having, for every point of the center axis, a shortest distance to the straight line. A second ratio of a specific distance to 1 meter, the specific distance being defined as a largest of all shortest distances. A product of the first and second ratio is smaller than 4×10−6.

Abstract: A method for producing a glass product is provided. The method includes providing a glass melt; hot forming the glass melt to obtain a glass product; and transferring the glass melt from a first region to a second region through a tube. The tube has a part that protrudes with a length into the glass melt in the first region. The part being at a distance from an inner base lying directly thereunder. The length and the distance are configured so that little defective glass gets into the tube and is transferred to the second region.
