Flange connection for quartz tubes
First Claim
1. Flange connection for a tubular element (1) which comprises quartz material, comprisingan essentially circumferential recess or ring groove (2) formed in the tubular element;
- a spring ring (3) retained in the recess or ring groove having a minor portion of its cross section located in the groove and a remaining and major portion projecting therefrom;
a flange ring (4) surrounding the tubular element, with clearance, and having an essentially conical surface (8) in engagement with part of said remaining and major projecting portion of the spring ring at one side thereof;
a counter ring (5) surrounding the tubular element, with clearance, and having an essentially conical surface (8) in engagement with part of said remaining and major projecting portion, and located opposite said one side of the projecting portion of the spring ring;
and clamping means (6) located beyond said projecting portion and clamping said flange ring and said counter ring onto the spring ring, with the remaining and major portion of the spring ring positioned between the flange ring and the counter ring, while securely holding the spring ring in said circumferential recess or ring groove (2) in the tubular element (1) and compressing the spring ring (3) radially inwardly.

Abstract
To connect together tubular elements, such as pipes and the like, made of materials which are difficult to machine and handle, and which are expensive, such as quartz glass, or quartz materials or quartz-ceramic goods used, for example, in laboratory or chemical processing apparatus, the end portions of the tubular elements are formed with a circumferential groove or recess in which a spring ring made of metal, fiber-reinforced plastic, or the like, is snapped, the spring ring (3) being clamped at its external, projecting surface by a conical surface (8) on a flange ring (4) and a similar conical surface (8) on a counter ring, the flange ring and the counter ring being clamped by connecting bolts (6); two such elements can be connected together by passing connecting bolts (10) through aligned openings (7) in the flange rings; preferably, the connecting bolts are spring-loaded (11). The engagement angles of the conical surfaces (8) on the rings are, for example, about 38° each with respect to a plane passing transversely through the axis of the tubular quartz goods.
