PIPELINER 16P
AWS: E7016 H4 Low Hydrogen Stick (SMAW) Electrode
We designed this quality electrode
for optimum performance for verti-
cal up welding of pipe up to API 5L-
X65 – especially where a low hydro-
gen deposit is desired. Obtain
Charpy V-Notch impact values down
to temperatures of -20°F (-29°C).
ADVANTAGE LINCOLN
• Excellent low temperature impact
properties.
• Square burnoff makes welding
easier, especially in critical pipe
welding applications.
• Manufactured under a quality
system certified to ISO 9001
requirements.
• Manufactured to actual lot control.
Actual certificates of conformance
are available upon request.
TYPICAL APPLICATIONS
• Primarily designed for vertical up
root and fill pass welding of high
strength pipe up to and including
API 5L-X65.
• Open gap root pass welding with
2.5mm (3/32”) and 3.2mm (1/8”)
diameters using DC± polarity.
