Lens
Ring Joint Gasket
Item No.:ZD-G1840
Description:ZD-G1840
lens ring joints' highest pressure used is 3000atm,they have been used
on pipe flanges in synthesizing line of ammonia and methand at high
pressure and high temperature,in high pressure polymerizing line of
polyethylene at 3000 atm.
Application:
ZD-G1840 is
suitable
to sealing of flanges at high temperature and pressure pipings It is
widely applied in petroleum processing,oil refining ,electricity
generated by firepower,textile and other light industries,pharmacy
,pipeline of nature gas,valve etc.
Standard：ANSI
B16.5-1973、JPI-75-15-70、GB 699、GB1220、JB755、HG20633-9
Note：The
material of the oval ring jont gasket must be 15~20HB
lower than the hardness of flange,and this kind of
gaskets is non-recyclable.

It is important to use proper packaging, handling and storage methods as
any bruise, gouge (dent, ding, etc.) or groove across the seal contact
area may prevent uniform coining and continuous intimate contact,
resulting in leakage in the area of damage. Any rough handling or
impact contact against hard surfaces or objects may cause damage to a
ring gasket that renders it unusable. Soft iron and carbon steel ring
gaskets must be kept dry to prevent rust and pitting.
The plating on these ring gaskets will provide some rust protection for
a short time but any extended storage in a damp atmosphere or wetness
may destroy the usefulness of these gaskets. Stainless steel ring joint
gaskets are more tolerant to wet and damp conditions.
