PIPELINER NR-207XPAWS: E71T8-K6 Self-Shielded Flux-Cored (FCAW-S) Wire Electrode

For consistently high impact values, choose 207XP. Optimum perfor- mance on vertical down, hot, fill and cap passes on standard cross-country pipelines and arctic grade pipe. Recommended for API Pipe Grades X42 through X70.

ADVANTAGE LINCOLN

Consistently high CVN properties, even down to -40˚F (-40˚C).

Virtually eliminates CVN values below 42 ft•lbf (56 joules).

Self-shielded, flux-cored. No need for external gas or flux.

Produces quality welds in moderate wind conditions with no tenting.

Our quality driven manufacturing system – certified to ISO 9001 – and our exceptionally high grade raw materials mean every coil of Innershield delivers great arc characteristics and superior feedability.

Manufactured to actual lot control. Actual certificates of conformance are available upon request.

TYPICAL APPLICATIONS

Suggested for use on applications demanding consistently high tough- ness.

Standard cross country pipelines.

Arctic grade pipe.

NOTE: Pipeliner elec- trodes are manufactured under lot control. A Certificate of Test showing actual deposit chemistry and mechanical properties per AWS A5.29 is avail- able on request from the factory for every lot of electrode.

(Fax 216-383-8386).

(1)The strength and elongation properties reported were obtained from a .505" tensile specimen artificially aged at 220°F (104°C) for 48 hours, as permitted by AWS A5.29-98. A naturally aged tensile specimen may take months to achieve the specified properties. The time required for the natural aging of weld deposits is dependent upon ambient conditions, weld- ment geometry, the metallurgical structure of the weld deposit and other factors.

(2)Standard testing completed to AWS test plate specifications.
