UDT Leopard
Connector

High-Strength, Rapid-Make-Up Connector for Demanding Drilling Environments – Engineered for Performance, Precision, and Pressure Integrity.

UDT LEOPARD

UDT-Leopard is the most popular high strength connector which has been used in many different applications environment and drilling programmes for land, platform, jack up, subsea/deep water including highly deviated deep well.Fitment in less than 1 turn rotation with inbuilt anti rotation feature and high pressure sealing.

UDT-Leopard combines the advantages of a preloaded thread-type connector and the rapid make-up in 5/8th turn desired for offshore operations. It has mechanical strength characteristics higher than those of the casing pipe.

Key features of all UDT Leopard Connector

Self-aligned & no cross threading

Strength characteristics higher than casing pipe.

Make-up in 4 turn from stab to full make up

4 turn rotation make-up prevents connector back-off

Suitable for piling/jetting.

Visual indication of make-up

Low torque make-up with rig tongs.

Preloaded for fatigues.

High-pressure sealing.

Reversible and reusable

UDT Swift

UDT-Swift is a heavy -duty threaded connector for use in exploration and platform casing strings where high strength and pressure integrity are important.

UDT Lynx

UDT-Lynx is a robust connector for conductor. It is the simplest type of connector to run, requiring no special tools or personnel. The connector is designed to meet.

UDT Puma

The Puma is a flush-threaded connector for use on exploration and platform drilling operations where size restrictions preclude the use of conventional upset connectors.
