General Design Notes and Considerations

The following design features should be applied to the discharge piping and header for approximately 90 m downstream from the PR valve in question. 

Use pipe with a minimum wall thickness of 13 mm to increase flexural stiffness. 

Use completely welded full wrap-around reinforcement pads at branch connections with pad thickness equal to header wall thickness. 

Use wrap-around reinforcement at welded support shoes and anchors. Alternatively, all welding of these fittings to the pipe wall may be eliminated by the use of bolted shoes and anchors. 

Eliminate all vents, drains and small diameter connections.
