What is Gandy's new Super Seamless?

OCTG manufactured from Super Duplex and nickel-based Corrosion Resistant
Alloys

Economically manufactured in OD sizes 7” through 9-5/8”

110 KSI minimum yield strength

Manufactured in typical OCTG wall and weight

Lengths up to 45-feet

Manufactured from Super Duplex, Alloy 28, Alloy 825, G3, and C276 Alloys

Superior uniformity in dimensional tolerances, ovality, wall, yield, tensile, and
length compared to OCTG manufactured from traditional seamless extruded
hollow

Hollows from defect-free plate roll formed with re-crystallized weldment by
shielded gas arc process using filler metal perfectly matched to the base metal

Cold-worked from hollows superior to traditional extruded seamless hollows

Advantages of Super Seamless - Super Duplex and
Nickel-Based OCTG

Substantially tighter dimensional and mechanical tolerances

More uniform ovality, wall, yield and tensile

More uniform length ( typical length variance is 4” per joint)

Longer lengths (presently available up to 45-feet) Longer is possible

Rig cost savings (fewer connections to make up)

Connections cost savings (fewer connections to purchase)

Reduced leak risk (less connections to leak)

Flexibility in choice of specialty connection from any manufacturer

Alternative source for large OD super duplex and nickel-based alloy OCTG

Immediately Increases overall worldwide manufacturing capacity for super
duplex and nickel-based alloy OCTG
