Twice the productivity
of welded pipe

A fitter/helper team can routinely field erect, fit-up, and install 50-60 LOKRING fittings in a single shift. This productivity more than doubles the rate at which welded piping systems are typically shop fabricated and field erected.

In addition to a reduction of labor hours of 50% or more, the labor-hour rate is reduced by reconfiguring welder/fitter crews to fitter/helper crews, lowering the composite crew rate by 10-20%.

This combination of greater productivity and lower man-hour rates translates into labor cost savings of 60% or more.

Total installed cost comparison

Without the welding overhead

By eliminating welding in the unit, many overhead costs relating to safety, personnel, equipment and supplies, inspection, rework, and monitoring can be eliminated or substantially reduced.

Some examples are:

Obtain fire permit for hot work
Erect scaffolding and provide ventilation
"Sniff" area, gas free and weather protect
Blank flanges and nozzles
Establish fire watch
Build fire box or tarps
Drain, flush and dry lines
Place equipment, electric cables, and purge line
Cranes, welders, grinders and small tools
Weld consumables (purge gas and filler rod)
Workers' compensation, insurance and benefits
Weld X-ray or other NDT
Rework of damaged or misaligned spools
System soak, flush, or passivation;
HAZMAT disposal
Maintain and monitor flanges for leakage

In addition, scarce ASME-certified welders are freed up for large bore pipe or pressure vessel welding.
