Efficiency Comparison
Permalok® Excels in Trenchless Technology Applications
Selecting Permalok® casing pipe over field-welded pipe provides an advantage you can take to the bank. Our proprietary airtight joints seal within minutes, compared to hours reserved for joint welding. The below examples demonstrate real savings in time and money in trenchless installations.
24” Steel Pipe Installation Comparison
Permalok Casing
Using the Permalok T-5 Joint, an install crew can make a watertight connection in 6 minutes. With each connection adding only minutes to the install time, a crew may install up to 10 pieces of 20’ casing pipe in an eight-hour shift.
End Results: 200 linear feet per day.
Welded Steel Casing
A skilled field welder takes an average 90 minutes to fit and butt weld one joint on 24” x .500” casing. The same size crew will only be able to install three to four 20’ long pipe in an eight-hour shift.
End Result: 60 to 80 linear feet per day.
60” Steel Pipe Installation Comparison
Permalok Casing
Unlike welding, the size of the pipe does not affect joint time. Again, the Permalok T-5 Joint is complete in 6 minutes. The install crew may install up to 10 pieces of 20’ casing pipe in an eight-hour shift.
End Results: 200 linear feet per day.
Welded Steel Casing
A skilled field welder takes on average 180 minutes to fit and butt weld one joint on 60” x .750” casing. The same size crew will only be able to install two to three pieces of 20’ long pipe in an eight-hour shift.
End Result: 40 to 60 linear feet per day.
