super seamless

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
