Achieve
predictable, reliable, repeatable, measurable and verifiable
joint performance. |
|
|
Seal the joint. |
|
|
Seal the joint at
bolt-up, during testing and during operation. |
|
|
Seal the joint at the pipe ID, not
just at the flange face OD. You only see leaks at the flange
face OD. Even though there are no visible signs of a leak, you
may have medium trapped between each side of the gasket and the
face of opposing flanges. |
|
|
Eliminate areas
in which "bugs" can grow -
| Seal at ID of the flange. |
| Fit the flange both before
and after bolt-up. |
| Create no
"pockets" at pipe ID under normal operating
conditions. |
| Minimize voids in the
gasket material. |
| Minimize gasket exposed
area and compressed (installed) thickness. |
| Provide even stress
distribution on the gasket and flange area. |
|
|
|
Minimize total cost of installed
flange, not just purchase cost of components at the
receiving dock. Installation cost includes purchase cost of
backing flange, gasket, fasteners and mechanical
contractor crew cost (labor, tools, scaffolding and clean room) and
project elapsed time. Costs at the receiving dock are the most
critical costs only if flange components are never installed. |
|
|
Arrive at dock
cleaned and ready to install. |
|
|
Simplify installation procedure. |
|
|
Reduce
installation time. |
|
|
Reduce chances for installation
error, while making allowance for such errors. |
|
|
Seal at pipe
manufacturer's torque values without requiring costly fasteners
(higher grade and/or PTFE-coated), or bolt lubricants. |
|
|
Reduce re-installation costs to fix
"leakers" during purge and testing. |
|
|
Help to
geometrically center the pipe for proper laminar flow. |
|
|
Minimize the hydraulic forces which
the joint must overcome - you do this by sealing at the flange
ID, not the flange OD. |
|
|
Eliminate the
distortion, and subsequent thermal set, of flange adapters
caused by conventional backing flanges and rings. |
|
|
Manufacture gasket from as pure a
material as possible. |
|
|
Mass produce
components. |
