Flanged with ring gasket
Ring Joint flanges
Flanges are matching disks of metal bolted together and compressing a metal gasket between their faces.
Made of a special metal alloy.
Placed between all flanged connections.
The ring gasket fits into specially machined groove in the upper and lower flanges.
It serves to contain pressures in the wellhead.
Each ring gasket is designed to withstand maximum pressure that the tubulars will be exposed to.
