Subsea & Risers

Subsea Pipelines

 Taper-Lok Connectors with a male/female self-aligning flange  configuration installs up to 75% faster and easier than ANSI or API  flanges.  CNOOC PL 19-3 Phase II project was installed 20 days early and  saved the client $3 million due to the ease of installation.  Taper-Lok  swivel and weld neck flanges can come with a spherical nose  configuration on the male flange which allows for 2-3 degrees of  misalignment. 

Subsea Risers

 Taper-Lok and CofferLok Compact Engineered Connectors are able to 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.  Applications include pipelines, flowlines, risers,  spools, tapered stress joints and flex joints.  Weld neck and swivel  flange configurations are available. 

Ball Misalignment Flange

 Taper-Lok MAF Connectors (Ball Misalignment Flange).  The  standard misalignment assembly (shown) allows up to 10-degrees of both  axial and angular misalignment of piping. When 10-degrees of  misalignment is not enough, then this assembly can be modified to  include a second ball joint that would allow for up to 20-degrees of  misalignment of piping.  This product is typically used in subsea  applications between the flowline and riser piping or for subsea  pipeline repair. 

Swivel Flange Misalignment Capability

 The Taper-Lok 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. 

Subsea Pipeline/Riser/Hull Piping Spools

 Taper-Lok Connectors with a male/female self-aligning flange  configuration installs up to 75% faster and easier than ANSI or API  flanges.  CNOOC PL 19-3 Phase II project was installed 20 days early and  saved the client $3 million due to the ease of installation.  Taper-Lok  swivel and weld neck flanges can come with a spherical nose  configuration on the male flange which allows for 2-3 degrees of  misalignment
