Patent WO-02101265-A1 (WO)
Title: Dichtungselement und dichtungsanordnung mit geringer leckrate
Inventor: HALBROCK BERND
IPC: F16J15/3236
Filed: 2002-06-12
Abstract: Zum Aufbau einer verbesserten Dichtungsanordnung (1) ist ein Dichtungselement (19) vorgesehen, das wenigstens einen Fussabschnitt (34) aufweist. Dieser ist von einem Stegabschnitt (31) in Axialrichtung federnd mit einem Grundkörperabschnitt (24) verbunden, der ähnlich einem O-Ring aufgebaut sein kann. Die axiale Federwirkung des Stegabschnitts (31) verhindert, dass der Fussabschnitt (34) von dem abzudichtenden Ringspalt abgehoben wird. Auf diese Weise bietet das Dichtungselement (19) dem abzudichtenden Fluid nur eine äusserst geringe Fläche dar, die der Querschnittsfläche des Ringspalts entspricht. Somit können sich nur geringste Fluidmengen in dem Elastomer des einstückig ausgebildeten Dichtungselements (19) lösen und dieses durchwandern. Das erfindungsgemässe Dichtungselement ermöglicht darüber hinaus die Unterstützung der Dichtwirkung durch eine so genannte aktive Dichtung. Bei dieser wird jedoch kein Teil des Dichtungselements von dem abzudichtenden Ringspalt wegbewegt. Vielmehr wird ein vorhandener Hohlraum (48) durch das Fluid druckbeaufschlagt und dichtet somit sowohl den zum Aufnahmeraum (18) hinführenden Ringspalt als auch den wegführenden Ringspalt ab.

Title: Electrostatic spray coating of large pipes - produces highly fluid coat giving firm bond and long life
Inventor: DOMALSKI WILLI
IPC: B05D7/14
Filed: 1973-09-06
Abstract: A method of producing a plastics coating on a metal object, by pre-heating of the metal and applying the plastics in powder form and electrostatically charges, is carried out in such a way that the quantity of powdered plastics applied per unit area of metal surface and the degree of heating are so related to each other that the resultant melted coating is sufficiently fluid to entirely wet the surface before it commences to thicken and set. The preferred method esp. for coating large diameter metal pipes, consists of moving the powder-spraying unit and pipe raltive to each other, and so adjusting the feed speed to the degree of heating and the powder application rate that the desired fluid spread of the plastics is obtained. Pref. epoxy resin powder is used, at an application rate such as to produce a coating thickness of approx. 100 micron. The process is used esp. for coating large dia. metal pipes. It has been found that the effectiveness of the coating against long term corrosion is a function not of its thickness but of the effectiveness of the bond between coating and metal. A prerequisite for this satisfactory bond is complete wetting of the metal surface by the plastics. This is achieved by having the plastics in a highly fluid state.
