Connector Benefits

Leak-Free Reliability

 Taper-Lok and CofferLok Connectors metal-to-metal seal ring technology  offers leak-free reliability over traditional ANSI and API gaskets. Our  seal rings offer the equivalency of welded joint integrity and can be  used in critical and chronic leak areas. 

Weight and Space Savings

 Our Engineered Connectors save weight and space. With weight savings of  up to 80% in comparison to ANSI flanges, our engineered connection  systems can typically save up to one million lbs. on offshore floating  platform topsides. These connectors also offer space savings of up to  82% with smaller outside diameter and length dimensions compared to  ANSI/API flanges. Pipe runs can be designed closer together to create  more room for process equipment and future tie-backs. Our connectors are  ideal for small O.D. pull-in-head requirements.

Withstands High External Loading

 Taper-Lok and CofferLok Compact Engineered Connectors can handle high  fatigue and high bending moments. We can optimize the design of the  connector as needed to meet project requirements. The design usually has  less weight and a smaller outside diameter than ANSI or API flanges. In  addition, our connectors typically use smaller bolt sizes and less  bolts that allow for easier handling and quicker make up times. Even  faster make-up times can be realized when using our Taper-Lok spherical  nose feature that allows for 2-3 degrees of misalignment on weldneck and  swivel designs. Applications include pipelines, flowlines, risers,  spools, tapered stress joints and flex joints. 

Quick Assembly

 Engineered Connector systems typically use fewer and smaller bolts in  comparison to ANSI or API flanges. Our catalog of connectors includes  clamps that only require four bolts and flange connectors that are  self-aligning and allow for misalignment. 

Less Cost, Less Size and More Reliable

 

Taper-Lok and CofferLok Connectors have many advantages over ANSI B16.5 flanges.

Weight Savings –Cost savings of $7 -$10 of capital  cost for each 1 lb. (.45 kg) reduction in offshore weight. Less pipe  weight to support.  Less freight costs.  Less weight for skids and  cranes (Smaller lifting barges).  Less support needed for heavy  installation.  Easier handling during fabrication and fit up.

Space Savings –Pipe runs are closer together.  More room for process equipment.  More room for future tie-backs.

Maintenance Savings –No leaks (how much does a leak  cost?).  No “hot work”, faster “through put” and reduces shutdowns.  No  corrosion/erosion problems.  Flange equipment and valves with “weld  integrity”.

Inventory Savings –Seal rings are designed to be reused

Misalignment Capability

 Our Engineered Connector systems have designs that are self-aligning and  offer up to 20º of misalignment capability.  The Taper-Lok weldneck and  swivel flange design with a spherical nose offers up to 3 degrees of  misalignment and can stay in the misaligned configuration while in  service.  During assembly, if the bolts can be installed through the  bolt holes, the connector can be made-up.  The picture shown is a  Taper-Lok swivel flange that has been in subsea service for over 10  years in the misaligned configuration. 

High Pressure and/or High Temperature Applications

 Our Engineered Connector systems have applications in high pressure  and/or high temperature where they outperform ANSI and API flanges in  terms of reliability and leak free service.  Pressures up to 20K psi and  temperatures up to 1,500 Deg F.
