4 THREADED CONNECTORS QUIKTHREAD CONNECTORS QuikThread Connectors offer fast makeup, reliable sealing and versatility to excel in a variety of drilling applications. Their rugged thread form and automatic selfaligning profiles allow for quick and easy installation in the field. QuikThread Connectors can be outfitted with antirotation keys for added security in harsh drilling environments. Recommended Applications For casing run from any floating rig where rig movement and deepwater current may be encountered For casing run from a dualactivity floating rig For lost circulation hole sections For riser casing strings in mudline suspension system wells QuikThread Connectors make up in twoandahalf turns and cannot be crossthreaded Only 2 1 /2 turns to fully make up FEATURES: QuikThread and MultiThread Easy stabbing Self aligning No crossthreading Fast makeup Low torque Visual indication of makeup High strength Highpressure sealing Driveable Antirotation devices available Reusable Fully tested Fieldproven technology Easily weldable The QuikThread Connector provides a fast and reliable means of running large diameter tubulars in any application. 2

5 MULTITHREAD CONNECTORS The MultiThread Connector is a member of the QuikThread line of connectors. It maintains the fieldproven performance of the QuikThread design with the advantage of making up in only 5/8 of a turn. Recommended Applications Shallow water applications All bottom supported drilling vessels or moored floating drilling vessels Applications where casing will be run directly into the hole MultiThread Connectors make up in less than one turn and cannot be crossthreaded Only 5 /8 turn to fully make up MultiThread Connectors and protectors have an identifying groove that easily distinguishes them from QuikThread Connectors Multiple thread start The MultiThread Connector provides a definite advantage for quick makeup of large diameter tubulars. 3

6 BENEFITS OF THREADED CONNECTORS EXCEPTIONAL STRENGTH Dr i lqu i p threaded connectors are manufactured from high quality ringrolled alloy forgings. The unique geometry of the connectors, combined with high quality materials, provide for optimum bending, tension and pressure capacities. RUGGED THREAD FORM The rugged thread forms of the Quik Thread and MultiThread Connectors are designed with a negative 5 angle on the load flank of the thread. This feature provides an interlocking force, ensuring a positive radial mechanical lock between the box and pin that prevents thread jumpout. The pitch of the thread provides for higher loadcarrying capacity while reducing stress concentration. The noninterference thread design reduces radial stresses in the connection. The steep thread taper provides thicker wall sections at the higher loadcarrying first threads of the pin and box. EASY STAB Can be stabbed even when pin and box are not perfectly aligned QUICK MAKEUP, LOW TORQUE Low final makeup torque simplifies installation SELFALIGNING Aligning profiles align connector prior to thread makeup; crossthreading is not possible RELIABLE SEALING CAPACITY A resilient seal located in the box provides reliable high pressuresealing capacity. The seal is located below the threads to prevent pressure migration through the threaded area for increased pressuresealing capacity. Dual metaltometal sealing is available as an option. POSITIVE ALIGNMENT Alignment profiles above and below the threaded section provide alignment before thread contact occurs. This unique design assures perfect alignment every time and prevents crossthreading. Rugged thread form 4

7 OPTIONAL CONNECTORS FOR FATIGUE APPLICATIONS FAST MAKEUP AND EASY HANDLING Dr i lqu i p QuikThread Connectors can be used in deepwater conductor pipe and production platform riser applications where longterm fatigue life is crucial. For these riser applications, Dr i lqu i p offers a thread form with a full root radius that dramatically decreases the Stress Amplification Factor and increases fatigue life. Connectors best suited for longterm fatigue applications are the Htype with drive shoulder on the pin and the HCtype. CONNECTORS WITH METALTOMETAL SEALS Dr i lqu i p offers a metaltometal sealing option on its QuikThread Connectors. Two metaltometal areas straddle the Oring groove in the box connector with a corresponding metal seal area on the connector pin nose. By adding the metal seal, the connectors become suitable for gas service Pick up the pipe according to normal rig operations; no special handling is required. Check pin connector for contamination or damage. If needed, reapply to the box connection a light coat of lubricant. Stab the pin into the box and slack off full joint weight on the connection. Rotate the joint to the right with power tongs or rig tongs. QuikThread: Rotate approximately 2 1 /2 turns to fully make up. MultiThread: Rotate approximately 5 /8 of a turn to fully make up. Perform final makeup torque according to table below. Confirm connector makeup by examining the visual indicator.

8 ANTIROTATION DEVICES Threaded connectors are often used in applications that require the use of antirotation devices. These devices prevent connection backout or overtorque that may occur as a result of torsional forces or impact loads. Torsional forces, for example, could be applied to the connectors during makeup/release of mudline suspension running and tieback tools and high current conditions. Also, impact loads generated during driving applications can result in connector backoff or overtorque. Antirotation keys are available to prevent these types of rotation. Driving applications frequently require antirotation keys Dr i lqu i p offers two types of antirotation devices: Horizontal Cam Key Vertical Slot Key The connector selected for a given application determines which key is used. HORIZONTAL CAM KEY Connectors designed with a secondary drive shoulder are designated Dtype connectors. These connectors are equipped with horizontal camtype antirotation keys. Horizontal Cam Key Camstyle antirotation keys are installed into a mating camshaped slot on the OD of the pin. Di a metric ally opposed keys are installed in opposite directions to prevent right or lefthand rotation. The hardened keys have serrations that bite into the top shoulder of the box. Any attempt to rotate the pin is immediately stopped by the camming action of the keys. The keys are retained in their slots by an Allenhead bolt and can be easily removed, if necessary. VERTICAL SLOT KEY Vertical Slot Key Connectors that do not have a secondary drive shoulder require vertical slot keys. When the key is installed into a slot in the pin, the serrations bite into the ID of the box, preventing rotation of the pin relative to the box. The key is captured in the slot to prevent disengagement during driving operations. The key does not protrude past the OD of the box and can be easily removed, if necessary. 6

18 DESIGN Dr i lqu i p specialty connectors are designed to offer superior operational and strength characteristics. The first step in the design process is the conceptual development of a connector that provides a fast, safe and efficient means of connecting casing joints under worstcase field conditions. Special attention is given to durability to avoid handling damage while in transport and/or running into the hole. Having met these requirements, the design is then refined utilizing computeraided finite element analyses to optimize the connector geometry regarding both static and cyclic fatiguetype loadings. Connector capacities are based on the maximum shear stress theory of failure. This theory, in generalized form, states that a material subjected to any combination of loads will fail (by yielding or fracturing) whenever the maximum shear stress exceeds the shear strength (yield or ultimate) of the material. Dr i lqu i p connector ratings are based on the following conservative design criteria: Engineering analysis of connector performed by Dr i lqu i p engineering department 1) the maximum membrane stress intensity should not exceed 2 /3 of the material yield strength; and 2) the maximum membrane plus bending stress intensity should not exceed the material yield strength. Stress intensity at a point is defined as twice the maximum shear stress at that point and is the maximum algebraic difference between the three principal stresses at the point. Membrane stress intensity is the stress intensity based on average principal stresses for the particular section. Membrane plus bending stress intensities at the inside and outside of a section are simply the stress intensities at these respective locations, but referred to as membrane plus bending stress intensities since both the section s resultant force and locally induced bending contribute to the stress. All specialty connectors are designed to be field compatible with the casing weight and grade to which they are attached. Dr i lqu i p s specialty connectors have been designed and modeled using the most advanced computer techniques 16

19 TESTING Prototypes of each Dr i lqu i p specialty connector type undergo extensive function and load testing. This testing verifies design, structural and operational specifications. FUNCTIONAL TESTING Repeated functional tests under simulated worstcase field conditions are conducted to: 1) Verify connector operational characteristics meet or exceed the design criteria 2) Verify repeatability and accuracy of connector stab, makeup and release 3) Verify connector ruggedness for handling Four Point Fatigue Test Facility 4) Perform drive testing where applicable 5) Monitor any unusual wear LOAD TESTING, bending and pressure testing are performed to: 1) Verify finite element analyses 2) Monitor connector performance under tensile, bending and combined tensile and bending loading conditions 3) Establish rated and ultimate capacities based on test data 4) Verify connector pressure ratings and seal performance Performing 22" Pin and Box Connector Test 17
