metallic ring gasket (oval gasket, octagon gasket and the lenspad),
Include the full range of R, RX, BX, the(product is mainly used for
flat plate gate valve, the Christmas tree, pipe fittings,flange,
pipeline gas field, wellhead equipment, petrochemical, oil
production machinery parts and other machinery and equipment.I We
can supply 30 kinds of material, such as iron, carbon steel, SS304,
SS321, SS316, SS347, Inconel 600, Monel 400, HastelfoyC276, Inconel
625, Incoloy825 etc., Can meet customer needs according to the
specific size requirements of customers or drawingproduction, the
maximum production of 2000mm products.At the same time, we also
produce metal winding pads, wave tooth composite pad, ladle pad and
non metal (asbestos gasket,non asbestos gasket, PTFE gasket PTFE
gasket and etc.). Through the introduction of CNC lathe, advanced
German spectrometer,Brinell hardness tester, coating thickness
gauge, laser marking machine series equipment, provides the high
quality product andservice to the customers. This seal will as in
the past to follow "grasp the quality of survival, to the
credibility of development, aconsistent policy of continued
improvement as the goal", the company with scientific management

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 lhought of as a half since the tight
closure. The Ring Type Joint was initially developed forhigh
pressure/temperature applications found in the petroleum industry
and is primarily used inthe oil field on drilling and completion
equipment. However,today this product rangecan also be found on
valvesand pipework assemblies, along with some high
integritypressure vessel joints.Standard Style R Ring Type Joints
aremanufactured in accordance with both API 6A and ASME B16.20
size/ratings. Available inboth oval and octagonalconfigurations,
both types are interchangeable on the modernoctagonal type grooved
flanges. Abide by the Lean quality, is the
sea always adhere to the faith. As long as it helps the
reali-zation of quality, ls willing to invest heavily in, The
purchase of advanced production and testing equipment, high-quality
team. The industry of new technology, new material, new technology,
