- Structure
The metal wound gadket is made of "V"-shaped or
"W"-shaped metal ribbon and non-metal ribbon
by continuously overlapping and winding.Both ends of metal ribbon
are spot welded.
- Features
(1) It is xuitable to wide application,high temperature
resistance,high pressure resistance
as cryogenic and vacuum condition.The combination of gasket
material can be modulated to meet
chemical corrosion resistance requirement.
(2) High stress compensation capability.Constant and reliable
sealing even at working position
under a fluctuated pressure and temperature.
(3) Perfect sealing performance.
(4) No overstrict requirement on the surface of flanges.
(5) Easy installation and low pre-tightening specific pressure.
- Gasket Types:
(1) There are four types:Hy-6035 Basic type gasket for motched
joint flange;Hy-6036 gasket with
inner ring for raised face flange;Hy-6037 gasket with outer ring
for smoothing flat welded flange
and ;Hy-6038 gasket with inner and outer rings for smoothing butt
welded gasket.
(2) The material:
(A) steel ribbon:304,1Cr18Ni9T(321),316 and 316L,etc.
(B) Ring:mild steel,oCr13,oCr18Ni9,304,316 and 316L,etc.
(C) Non-metal ribbon:flexible graphite,special-purpose
asbestos,Teflon and non-asbestos sheet.
- Application
(1) Working temperature: -196℃
to 700℃
( not higher than 600'C in oxidative medium )
(2) Working pressure: ≤ 25MPa
(3) Gasket coefficient: m=2.5 to 4
(4) Minimum pre-tightening specific pressure: y=68MPa
