Welded ID Wall Seal Type
For Secondary Fluid Containment
This completes the In-Plant Lock Ring Manufacturing Process.
The following demonstration will take us through the process used for manufacturing a pair of Joint Lock Rings for Secondary Fluid Containment.
The face O-Ring restricts the internal fluid from reaching or affecting the weld zone.
A pair of rings are machined from carbon steel to specific tolerances based on the mainline pipe size/wall thickness in which they will be inserted.
Grooves are machined when fitted with Viton O-Rings.
The internal surfaces of the rings that will contact service fluid are coated with a wear resistant, non conductive ceramic or molded Viton rubber lining.
A Heat resistant Viton fluorocarbon rubber O-Ring is then fitted in the machined groove.
