Title (EN) METAL SEAL WITH CORROSION RESISTANT ALLOY OVERLAY
(FR) JOINT METALLIQUE COMPRENANT UN REVETEMENT EN ALLIAGE ANTI-CORROSION
Abstract: front page image
(EN)A composite metal sealing ring and method are provided for sealing between tubular members. First (12) and second (14) tubular members have first (22) and second (24) conical inner sealing surfaces. A metal sealing ring (20) has corrosion-resistant inlays (16 and 18) defining opposing outer sealing surfaces for sealing with the first and second conical inner sealing surfaces. The resulting composite sealing ring has the corrosion-resistant benefits of stainless steel at the sealing surfaces, along with the desired expansion ratio of a conventional carbon steel.
(FR)L'invention concerne un joint d'étanchéité métallique composite et un procédé permettant de conférer une étanchéité entre des éléments tubulaires. Des premier et second éléments tubulaires comprennent des première et seconde surfaces d'étanchéité coniques internes. Un joint d'étanchéité métallique comprend des incrustations anti-corrosion définissant des surfaces d'étanchéité coniques externes opposées et destinées à être scellées aux première et seconde surfaces d'étanchéité coniques internes. Le joint d'étanchéité composite obtenu présente les avantages de l'acier inoxydable concernant la résistance à la corrosion au niveau des surfaces d'étanchéité, conjointement avec le taux d'expansion souhaité d'un acier ordinaire classique.
