    • A preferred embodiment of the present invention comprises a vitreous quartz pipe or container having a connector including a flange formed from at least one strip or rod-shaped piece of transparent quartz glass which is wound circumferentially around either an inner or outer surface of a portion of the pipe or container and secured to the pipe or container to thereby form a closed-ring flange. The portion of the pipe or container having the attached flange may be an open end of the pipe or container or may be a wall portion where a connector for mounting to fixtures or other fittings may be desired. This type of strip or rod-shaped piece of quartz glass can be made via a conventional pulling technique such that a strip or rod having the appropriate uniform cross-sectional shape is obtained. The prepared strips or rod-shaped pieces are then easily cut with a saw device to appropriate lengths. According to a preferred method of the present invention, a small portion of a strip or rod-shaped piece of transparent quartz glass is made pliable with the direct application of heat. As the portion of the strip or rod-shaped piece of quartz glass becomes pliable, the strip or rod-shaped piece of quartz glass is made to conform to the curvature of the underlying inner or outer pipe or container surface.

    • The invention relates to a known method for drawing a quartz glass cylinder from a melt crucible comprising an inner crucible chamber extending in the direction of a center crucible axis and bounded by a side wall and a floor, wherein SiO2 granulate is fed into the melt crucible and therein softened into a quartz glass mass, and said mass is drawn vertically downward as a cylindrical quartz glass strand by means of a first draw-off device through a first draw nozzle provided in the floor of the melt crucible, and the quartz glass cylinder is cut off therefrom. In order to disclose a method starting herefrom and allowing the production of homogenous quartz glass cylinder at simultaneously high levels of productivity, the invention proposes that at least one second quartz glass strand is drawn off through at least one further second draw nozzle provided in the floor of the melt crucible, wherein the first draw nozzle and the second draw nozzle are disposed eccentrically to the center crucible axis and at a distance from each other.

    • In a known melting crucible for use in a crucible drawing method, it is provided that the interior face of the crucible wall facing a crucible interior space is covered at least partially with a protective layer made of a noble metal. The known melting crucible does have good corrosion resistance with respect to the quartz glass melt, but the material costs are high because of the expensive coating metals. In order to provide a melting crucible for use in a crucible drawing method for quartz glass that exhibits good corrosion resistance at low material costs, it is proposed that the protective layer (2) be composed of a gas-tight, oxidic material that is not subject to a phase transition in the temperature range of 20° C. to 1800° C., and that the crucible interior space (17) have a gas space (17) above the quartz glass mass (27) to be held, and that the protective layer (2) be provided exclusively on the surface of the melting crucible interior face adjacent to the gas space (17).

    • In a known method for drawing a tubular quartz glass strand, a crucible is fed with SiO2-containing start material, the start material is softened in the crucible and, as a softened quartz glass mass, is drawn vertically downwards as a tubular quartz glass strand along a drawing axis through an annular gap between an outer member and an inner member, which is arranged in a through hole of the outer member, of a drawing nozzle provided in the bottom area of the crucible. To improve the known method with respect to less inhomogeneity in the drawn-off tubular strand and thereby to permit the manufacture of homogeneous, defect-free hollow cylinders of quartz glass by drawing from the melt, it is suggested according to the invention that the inner member of the drawing nozzle, viewed in the direction of the drawing axis, is held suspended and radially movable inside the through hole of the outer member, and that the annular gap of the drawing nozzle has a longitudinal section “L” in which its cross-sectional nozzle area is reduced in size from the top to the bottom.
