No Welds. No Flanges. No Leaks... No Kidding!

·  Permanent metal-to-metal seal

·  Intrinsically safe - No hot work

·  Qualified to ANSI/ASME B31 code

·  Quick and easy installation

·  Save up to 50% in total job costs

·  Over 1,000,000 fittings installed

                  

 

 

 

 

 

Our connector makes field erection and installation of small bore piping systems fast and virtually error-free. Because installation is intrinsically safe, fittings can be used in areas where flammable or explosive conditions may exist, without costly plant downtime. The bottom line? Dramatic reductions in the time and cost to field or repair small bore piping systems.

ANSI B31 QUALIFICATIONS AND TESTING

 

 

Our both stainless and carbon steel fittings are qualified to the requirements of the ANSI/ASME B31 pressure piping codes for pressure and fatigue design, and materials of construction. Extensive mechanical and environmental testing has demonstrated the mechanical and sealing integrity of the LOKRING connection in a wide range of applications and environmental conditions.

lokfig5.jpg

Pressure-torsion testing: Seen in the first picture above, the 1/2" NPS stainless steel test fitting was subjected to torsional loading high enough to twist the pipe in a spiral without leakage of the joint. Afterwards, during hydraulic testing, the pipe ruptured at 22,000 psi (1497 Bar).

 

Flexural testing: The 2" NPS carbon steel (seen in the second picture above) has been deflected to 3x the yield strength of the matching pipe without leakage. The performance of this fitting in severe bending, fatigue, and vibration loads is comparable or superior to a socket weld fitting.

 

Fire testing: The metal to metal LOKRING seal remains intact when subjected to extreme thermal loads, including fire (seen in the third picture above). Both stainless and carbon steel LOKRING fittings have met the requirements of the API-607, and the ASTM-A1387 (U.S. Navy) fire tests, and are widely used on volatile and flammable services.

 

 

 

 

 

 

 

 

 

 

LOWER TOTAL INSTALLED COST

 

Twice the productivity of welded pipe...

A fitter/helper team can routinely field erect, fit-up, and install 50-60 of our 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 in 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 (see Fig. ).

Although the cost of a this fitting is higher than the same configuration of weld fitting, the labor cost savings more than offset the increased material cost, resulting in a total installed cost savings of 20-30% or more.

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:

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