API R/Rx/Bx/IX Metal Ring Gasket/Octagonal/Oval Ring Joint Gasket

Product Description

METAL RING GASKET

RX/SRX TYPE METAL RING GASKET The metal ring pad is made of metal material by forging and heat treatment and machining into cross section shape is the entity of RX type metal gasket,have radial since the tight sealing effect,is a kind of special metal octagonal ring gasket,its action principle is cushion for leaning on and flange type laddergroove (mainly the lateral)out of contact,and through the pressure sealing function to form.RX metal ring gasket installed inside a ladder type ring grooveon the surface of the flange,when screw down the connecting bolt,the axial compression and up and down the ladder type slot 1,produce plasticdeformation,forming a ring seal belt,establish the initial seal After booster,under the action of medium pressure,make the ring gasket radial expansion.Gasket with trapezoidal groove cant post more tightly,self-tightening efetc.Medium pressure increases,however,also can make the flange and theconnecting bolt deformation,caused by a relative separation between the sealing surface,gasket seal than relative decline,RX type metal ring gasketbelongs to pressure from the ring gasket.Some size of the RX type ring gasket should be well versed in ring cross section pressure hole.
ETAL LENS GASKET High pressure pipe connection,thewidely used lens gasket sealing structure.Lens gasket seal face were spherical,contactwiththepipelineconesealing faces,the initial state for a loop.Underthe pre-tightening force,lens pad in contact produce plastic deformation,the looD into a ring,good sealing performance. Due to the contact surtace is made up ofspherical and cant naturally formed,in agasket is easy. Lens gasket seal belorgs to forced sealing,sealing surface for spherical surface and conical surface contact.easy appear indentation,poor interchangeability of parts,In addition,the gasket manufacturing cost is higher,processing also more difficult.
