9. ATTACH INFLATION HOSE TO ENABLE PLUG INFLATION
AND DEFLATION FROM OUTSIDE THE DANGER ZONE.
SELECT AN INFLATION HOSE AND OTHER ACCESSORIES. Cherne
sells ination extension hoses and lifting/ination hoses (Poly-Lift Lines).
Many of Cherne’s larger pneumatic plugs are supplied with a second
access port into the plug ination area (contact Cherne toll free at 1-800-
843-7584 for a list of plugs equipped with read back ports). This additional
port allows attachment of a calibrated pressure gauge which provides
continuous and accurate measurement of ination pressure. The length and
type of ination hose needed will vary depending upon job site conditions
but it must be of sufcient length to allow plug operation from outside the
Danger Zone. When using a larger pneumatic plug, always secure a line to
the plug’s eyebolt(s) or other attachment point(s) before use. This will assist
safe plug placement and plug removal. It also helps prevent inadvertent
loss of the plug in a pipeline. A Poly-Lift Line with rope and anchor hooks is
designed for this purpose. Ensure that any other ination hose selected has
sufcient strength to safely support the weight of the plug and accessories.
Extension hoses and Poly-Lift Lines can be interchanged between various
sizes and styles of pneumatic pipe plugs or linked together to allow
operation from greater distances. Additional optional accessories allow
plugs to be optimized for specic job requirements. Call Cherne toll free at
1-800-843-7584 for recommendations.
