Cixi Jayu Sealing Materials Co.,Ltd is one of the leading China 316 lens gaskets manufacturers, welcome to wholesale cheap 316 lens gaskets, lens type gasket from our professional factory. Lens
ring gasket, also known as washer with ball face, is mainly used
for the high pressure pipe connections. The primary function of lens ring
gasket is to seal. Metal lens gaskets includes metal flat gasket,
triangular gasket, double cone ring, C-ring and C type gasket, ring gasket,
serrated gasket, wave gasket and hollow o-ring, etc.. Perforated lens ring gasket is used for the flange seal of high
pressure pipe. Blind lens ring gasket is used for the
blind flange seal of high pressure pipe. The materials of lens ring gasket use
the forgings, rolled materials and pipes. Blind lens ring
gaskets use the forgings an It is wide to use the lens ring gaskets to seal in the high pressure pipe
connections. Seal faces of lens ring gaskets are ball surface, in contact with
conical sealing surface of the pipe, the initial state is in a loop. By the
action of the preload force, lens ring gasket has a
plastic deformation at the contact point and the loop is into a belt loop,
which has the better sealing performance. The contact face is naturally formed
by spherical surface and beveled surface, so the gasket is easy for alignment.
Lens ring gasket is the forced seal gasket. Structural Form Features 1.Lens
ring gasket is applicable for the pipe seal that the pressure
isn& acute;t lower than 10MPa. 2.Lens ring gasket is of line seal,
large expansion and contraction, large compensation and easy compact. 3.Due to contact with flange cone
face, it is easy to have the pressing mark. The interchangeability of part is
poor. 4.Lens ring gasket is also pressure
energized, as well as the double-cone gasket. 5.The
hardness of lens
ring gasket must
be15~20HB lower than the mating flange face hardness. Performance Parameters gasket factor m=5.50-6.50 gasket
?using pressure <=32MPa gas
