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.
BX/SBX Type Metal Ring Gasket
The metal ring pad is made of metal materlal by forging and heat treatment and machining into cross section shape is the entily of BX type metal gasket,have radial since the tight sealing efect, is a kind of specal metal octaganal ring gasket. its action principle is cushion for leaning on and flange type ladde groove (mainly the lateral) out of contact,and through the pressure sealing function to form.
The BX ring gasket differs from the standard oval or octagonal shape since it is square in cross section and tapers in each comer, All BX ring type joints inencorporale a prossure passage hole to allow for pressure equalization each side of the sealing faces ,On assembly, metal to contact of the flange faces is achieved. They can only be used in API 68X flanges. BX is used at pressures up to 20,000 psi.
R SERIES METAL RING PAD
The metal ring pad is made of metal material by forging and heat treatment and machining into cross section shape is the entity of octagon metallic gasket,have radial since the tight sealing effect,is a standard type R a kind of metal ring gasket,its action principle is cushion for leaning on is with flange typeladder groove (mainly the lateral)out of contact,and through the pressure sealing function to form.
Type R metal ring gasket installed inside a ladder type ring groove on the surface of the flange,when screw down the connecting bolt,the axialcompression and up and down the ladder type slot 1,produce plastic deformation,forming a ring seal belt,establish the initial seal.After booster,under theaction of medium pressure,make the ring gasket radial expansion.Gasket with trapezoidal groove cant post more tightly,self-tightening effect.Mediumpressure increases,however,also can make the flange and the connecting bolt deformation,caused by a relative separation between the sealing surface,gasket seal than relative decline,thus,ring gasket can be thought of as a half since the tight closure.
